Description: Pharmaceutically active aromatic Guanylhydrazones Specification The present invention relates to aromatic guanylhydrazone comunds and their use as pharmaceutically active agents, especially for prophylaxis and treatment of virally caused diseases and infections, including opportunistic infections. The inventive guanylhydrazone compounds are also useful as inhibitors of deoxyhypusine synthase and as inhibitors for nuclear export in infectious diseases and may be used to regulate the bactenally induced TNF-α production. Furthermore, the aromatic guanylhydrazones exhibit antibacterial activity against Gram positive and Gram negative bacteria and can be regarded as a novel class of antibiotics. In addition, methods for treating virally or bacterially induced infections and diseases are disclosed together with pharmaceutical compositions useful within said methods. HIV and AIDS: History Deaths from what has since been recognized as HIV infection with immune failure have been seen clinically, without being understood, for at least 35 years, and probably much longer. An HIV-infected British sailor, who had traveled widely, is thought to have died with severe immune deficiency and HIV infection in 1959, the earliest proven case of modern AIDS. The genetic material of the most common HIV-1 strain is most similar to that of a virus known to naturally infect chimpanzees, and it may be that HIV's ancestors have been present in Africa, perhaps even in humans, for a very long time, perhaps thousands of years. In West Africa, a close cousin of the HIV-1 , called HIV-2, is almost identical to several indigenous African monkey viruses, and almost certainly has been derived from them quite recently in virus evolutionary time (less than several centuries). First, the term "AIDS" stands for Acquired Immune Deficiency Syndrome, but it has always been understood that the amount of immune deficiency we are interested in, is not a trivial one. AIDS is the name historically chosen for a new medical syndrome which is essentially 100% fatal, and thus in defining "AIDS" we are looking for people with an immune deficiency in the range which is life- threatening, and which will continue to grow relentlessly worse until life is impossible. One way to define immune deficiency is to define it by so-called "opportunistic infections", diseases rarely seen in people whose immune system is fully functional. In the early days of AIDS, before HIV was discovered, the syndrome was indeed defined using such opportunistic diseases. Early in the history of AIDS, it was found that the immune defect in this disease is peculiar, and that it most visibly involves a particular kind of cells in blood and lymphatic tissues (lymph nodes), called "T-lymphocytes". In the syndrome of AIDS, certain T-lymphocytes gradually disappear from both blood and lymph tissues, and a simple T-lymphocyte count in the blood can tell how serious the reduction has been in both places (since blood lymphocytes come from the lymphatic organs). The arm of the immune system which is controlled most directly by T-lymphocytes (the body's defense against viruses and fungi) is most defective in AIDS, and viral and fungal infections are the main opportunistic infections which appear and cause death in AIDS. After HIV was identified, statistical studies quickly picked it as the most likely answer yet proposed for the cause of AIDS. HIV has the typical lentivirus structure, identical to that of FIV and SIV. People infected with HIV were found to develop antibodies to it in the blood usually a month or two after infection, and keep them for life. The presence of antibodies in the blood for years did not seem to keep people with HIV from eventually becoming very ill, however. Today, it is known that lentiviruses are able to mutate to escape host antibodies, so that antibodies found in the same blood with these viruses often do not neutralize them, especially late in the course of disease [J. Acquir. Immune. Defic. Syndr. 7:211-219, 1994]. The HIV preferably infects CD4+ cells which get lost in AIDS patients. Most people, however, apparently recovered completely after initial HIV infection, and felt well. As with other lentiviruses, the long latency period of HIV before secondary disease was striking. In a person with AIDS, up to 13% of lymphocytes and monocytes in the blood were found infected [N Engl J Med 326:1385-1391 , 1992]. From 93% to 100% of the time, infectious virus and viral DNA could be recovered from the blood of asymptomatic people who were HIV- positive, and 100% of the time from people with AIDS [N. Engl. J. Med. 321 :1621 - 5, 1989; AIDS 6:373-377, 1992; AIDS 8:895-900, 1994]. Higher levels of virus could be cultured from the lymphatic tissues of such people, where it was multiplying actively, even in people who appeared healthy [Clin Res 40:333, 1992; Proc Natl Acad Sci USA 88:9838-9842, 1991 ; J Infect Dis. 164:1051 -1057, 1991 ; J Acquir Immune Defic Syndr 6:655-662, 1993]. Like SIV-infected monkeys and FIV-infected cats doomed to future immune failure, HIV-positive people were still infected, and most were still slowly losing immune cells in lymphatic tissues. Opportunistic infections often also appeared, such as Candida yeast infection in the throat (often the first infection), or the unusual fungal pneumonia caused by Pneumocystis caήnii (this organism is particularly suppressed by CD4+ lymphocytes, and so is one of the first infections to arrive when their numbers fall). With the appearance of these markers of secondary disease, now the infected person was said to have "full-blown AIDS," or simply, AIDS. Lentiviruses The spread of lentiviruses in nature involves a complex bio-ecologic system in which host, parasite, and a range of social and environmental problems interact. The viruses are disseminated exclusively by exchange of body fluids. All factors that facilitate such exchange on a large scale may potentiate epidemics and epizootics. Similar criteria of viral genomic organization, morphology, and biological properies let to the inclusion of human immunodeficiency virus (HIV) into the lentivirus family. Originally called lymphadenopathy-associated virus (LAV), human T-cell lymphotropic virus III (HTLV-3), or AlDS-associated retrovirus (ARV) by the respective pioneers in the field, the name HIV was substituted by the Virus Nomenclature Committee. Subsequent new inductees into the lentivirus family, based on similar criteria, were the simian, feline, and bovine viruses. All these agents were called immunodeficency viruses (following the precedent of HIV) irrespective of whether they caused immunodeficency or, for that matter, any disease at all. The following table 1 gives an overview of the members of the lentivirus family known by now. Table 1 : Lentiviruses SIV and FIV were discovered several years after HIV and the lesson that remains from the SIV and FIV studies is that lentiviruses alone in some circumstances are quite capable of causing slow immunosuppressive death. FIV is called "Cat AIDS". The feline immunodeficiency virus (FIV) is a lentivirus discovered in Petaluma, California in 1986, where it was first obtained from the blood of two domestic cats living in a household in which there had been a number of deaths of cats from a strange immune deficiency disorder. With respect to the numbers of HIV-infected individuals, each day about 16,000 people worldwide are infected with the virus, with 95% of new cases ocurring in developing countries (mostly Africa). More than 2.6 milion people died of AIDS in 1999 alone, the highest reported number since data gathering about the disease began in the early 1980s. According to the American Medical Association, about 45 million people worldwide are infected with HIV. Of the more than 2.6 million people died of AlDS-associated diseases in 1999, an estimated 550,000 were children under 15 years of age. Although life expectancy increased very significantly by introduction of new treatments, at the present time no cure exists for AIDS. Hepatitis B Virus (HBV) Hepatitis is an inflammation of the liver that is most often caused by infection with one of five viruses, hepatitis A, B, C, D or E. in cases, particularly in those related to hepatitis B and C, "chronic hepatitis" may result. Chronic hepatitis occurs when the body is unable to completely clear the virus even though the symptoms may not persist. Continued presence of the virus over a number of years can lead to cirrhosis (scarring of the liver) or hepatocellular carcinoma (liver cancer). It is estimated that approximately 350 million people worldwide are infected with chronic hepatitis B. HBV is transmitted through sexual contact, vertical transmission (mother to child at birth) or by coming into contact with contaminated blood. It is estimated that over 2 billion people worldwide have been infected with hepatitis B virus. Of these 2 billion, approximately 350 million people have developed chronic HBV infection, putting them at high risk of developing cirrhosis and liver cancer (World Health Organization Fact Sheet on Hepatitis B, Nov. 1998). INCIDENCE: 140,000-320,000 infections/year in United States PREVALENCE: Estimated 1 -1 .25 million chronically infected Americans COSTS: Estimated $700 million (1991 dollars )/year (medical and work loss) Chronic carriers of the HBV have been defined as those who are HBV surface antigen positive for greater than 6 months. Approximately 5-10% of those people who are infected with the virus will become carriers, an estimated 5-10% of those people infected each year will progress to chronic liver disease, cirrhosis and possibly liver cancer. About 5,000 people die in the United States each year related to HBV, 1 ,000 die of HBV-related liver cancer. The incubation period of HBV usually lasts from 2 to 4 months, although it may be very short (10 days) or extremely long (9 months). Before the outbreak of the acute disease HBs- and HBe-antigen are detectable in the patient's serum. The onset of acute hepatitis is characterized by the occurrence of anti-HBc antibodies which at first exclusively belong to the IgM class. From this time on anti-HBc antibodies will be detectable in the patient's serum for the rest of his life, no matter whether there is an acute hepatitis B, a form of persisting virus infection or some naturally acquired immunity to HBV. The most significant event indicating a chronic course of hepatitis B is the absence of the HBsAg/anti-HBs seroconversion. If this phenomenon has not occurred within 6 months after the onset of the disease, persistence of the HBV infection and the related clinical pictures (asymptomatic HBsAg carrier, chronic hepatitis, cirrhosis, or hepatoma) have to be reckoned with. While monotherapy treatment with either Epivir-HBV (lamivudine, 3TC) or Intron A (interferon-alfa) shows some benefits for chronic hepatitis B, there is a need for additional therapies. Currently, drugs that are in development include Coviracil/FTC, DAPD, L-FMAU (Triangle Pharmaceuticals), adefovir dipivoxil, tenofovir (Gilead Sciences), epavudine, epcitabine (Novirio Pharmaceuticals), as well as lobucavir, Famvir/penciclovir, entecavir/BMS-200475, racivir, DXG, L-ddA prodrug, HDP-P-acyclovir, LM-019c, CS-1091 , PS-019, PS-018, ara-AMP prodrugs, thymosin, (-)-Carbovir, hammerhead hbozymes. and glycosidase inhibitors. Therefore, new antiviral drugs are highly needed.

Transmission of this virus through the air or blood does not normally occur. The incubation period, or the time from infection to appearance of symptoms, ranges from 4 to 6 weeks. Persons with infectious mononucleosis may be able to spread the infection to others for a period of weeks. However, no special precautions or isolation procedures are recommended, since the virus is also found frequently in the saliva of healthy people. In fact, many healthy people can carry and spread the virus intermittently for life. These people are usually the primary reservoir for person-to-person transmission. For this reason, transmission of the virus is almost impossible to prevent. The clinical diagnosis of infectious mononucleosis is suggested on the basis of the symptoms of fever, sore throat, swollen lymph glands, and the age of the patient. Usually, laboratory tests are needed for confirmation. Seroiogic results for persons with infectious mononucleosis include an elevated white blood cell count, an increased percentage of certain atypical white blood cells, and a positive reaction to a "mono spot" test. There is no specific treatment for infectious mononucleosis, other than treating the symptoms. No antiviral drugs or vaccines except Ganciclovir are available. Human herpesvirus 8 (HHV8), or Kaposi's sarcoma-associated herpesvirus (KSHV) KSHV is a virus belonging to the family of herpesviruses. KSHV was discovered in 1994. The virus has two names that are commonly used: KSHV which is its descriptive name and HHV8 which is its formal name. Both names are essentially interchangeable. KSHV causes a blood vessel cancer called Kaposi's sarcoma (KS), a lymphoma (a cancer of the lymphocyte) called body cavity-based lymphoma and some forms of severe lymph node enlargement, called Castleman's disease. The rates of KSHV infection in the general population of Mediterranean countries (Italy, Greece, Israel. Saudi Arabia) are higher than in North America and Northern Europe. Adult populations in some portions of Africa have very infection rates (>50%) In several respects the global patterns of KSHV infection appear to be similar to those of the hepatitis B virus although we are still at an early stage of understanding the epidemiology of KSHV This virus can be transmitted through sexual contact KSHV is also probably transmitted to some extent through nonsexual routes, perhaps from oral contact (kissing), particularly in Mediterranean and African countries Transmission directly from a pregnant mother to her fetus appears to be rare, although very young children can become infected after birth, particularly in Africa This is a common feature for some herpesviruses in that infection with these viruses is general and occurs at an early age in impoverished countries KSHV can be transmitted during organ transplantation although this appears to be uncommon Once exposed to KSHV, infection is probably life-long and the immune system of healthy adults keeps the virus in check at extremely low levels The real problem with KSHV occurs when an infected person becomes immunosuppressed This occurs among transplant patients and patients receiving chemotherapy There is good evidence that if someone is infected with KSHV and becomes immunosuppressed, then their chances of developing clinically detectable disease due to KSHV is higher than for other common viral infections Infection with KSHV is diagnosed by a blood test. It now seems likely that early in the AIDS epidemic there were actually two simultaneous virus epidemics the well-recognized epidemic of HIV and a second 'silent' epidemic of KSHV Only those persons who became immunosuppressed by HIV developed KS KSHV is probably less transmissible than HIV, certainly this is true from blood products and sharing needles, and so only the fraction of persons developing AIDS were infected with KSHV and developed KS KSHV- related disease can also occur in persons without obvious immunodeficiency, but this is rare and primarily occurs among elderly men There has been a major epidemic of KS in some parts of Africa, especially Eastern and Southern Africa, concurrent with the African HIV pandemic KS is now the most common tumor reported in several African cancer registries While most African KS patients are also HIV infected, these areas also have the world's highest rates of this disease for non HIV-infected persons There is no vaccine for KSHV Existing therapy is Ganciclovir Varicella-zoster virus (VZV) Chicken pox is an infection that is caused by the Varicella-zoster virus (VZV) VZV spreads in nasal discharge and in fluid from inside the chicken pox blisters. Chicken pox is very contagious and 90% of people who are not immune will catch it when they are exposed Epidemics are most common in the late winter and early spring, and children between ages 5 and 9 account for half of all cases. Normally, chicken pox is a mild illness, but it can cause serious complications, including pneumonia, encephalitis, and serious bacterial infections of chicken pox blisters. After causing an attack of chicken pox, VZV remains in the body. It lies dormant in nerve cells and may be reactivated later in life to cause shingles. Children (and others) who develop varicella and have weakened immune systems may be treated with Acyclovir Adenoviruses Adenoviruses are a frequent cause of acute upper respiratory tract infections. In addition, they also cause a number of other types of infection. They were first isolated in 1953 by investigators trying to establish cell-lines from adenoidal tissue of children removed during tonsillectomy and from military recruits with febrile illness. Certain types of Adenovirus are commonly associated with particular clinical syndromes- Acute Respiratory Illness, Pharyngitis, Conjunctivitis, Keratoconjunctivitis Most Adenovirus infections involve either the respiratory or gastrointestinal tracts or the eye. Adenovirus infections are very common, most are asymptomatic. Most people have been infected with at least 1 type at age 15 Virus can be isolated from the majority of tonsils/adenoids surgically removed, indicating latent infections It is not known how long the virus can persist in the body, or whether it is capable of reactivation after long periods, causing disease (it is hard to isolate this occult virus as it may be present in only a few cells). It is known that virus is reactivated during immunosuppression, e g in AIDS patients There is no therapy for Adenoviruses Inactivated vaccines have been developed and are routinely used for military recruits in some countries (e g USA) This is because adolescents and others in close daily contact are at risk for epidemic spread of respiratory infections In recent years, there has been considerable interest in developing Adenoviruses as defective vectors to carry and express foreign genes for therapeutic purposes One reason for this is that the Adenovirus genome is relatively easily manipulated in vitro and the genes coupled to the MLP are efficiently expressed in large amounts Respiratory syncytial virus (RSV) Respiratory syncytial virus (RSV) is a major cause of respiratory illness in young children RSV infection produces a variety of signs and symptoms involving different areas of the respiratory tract, from the nose to the lungs In children younger than age three, RSV can cause a lower respiratory tract illness like bronchiolitis or pneumonia and may lead to respiratory failure In this case, symptoms may include high fever, severe cough, wheezing, abnormally rapid breathing, difficulty breathing, and a bluish color of the lips or fingernails caused by lowered levels of oxygen in the blood In infants with severe RSV infection, there may be abnormal retractions of the muscles between the ribs, as the child struggles to draw breath into infected breathing passages RSV infections occur all over the world, most often in epidemics that can last up to five months, from late fall through early spring Since 1990, epidemics have typically begun sometime between late October and mid-December, and peaked during January and February Each year during these epidemic periods, about 90,000 infants and young children are hospitalized with RSV infections - and about 4,500 die The highest rates of RSV illness occur in infants two to six months old, with a peak at age two to three months RSV infection is often carried home by a school- aged child and passed onto a younger one, especially an infant When RSV infects a day-care center, it is not unusual to see 100% of the children come down with an RSV infection RSV commonly spreads through hospitals, too infecting both patients and staff Prevention and treatment RespiGam is a vaccine used to protect infants who are considered to be at high risk for severe illness if they are infected with RSV, such as those with chronic lung diseases This intravenous preventive treatment takes several hours to administer and must be repeated monthly during RSV season A similar vaccine, Synagis, has become available more recently It has replaced RespiGam as the treatment of choice for most high-risk children because it's given as monthly intramuscular injections, making it more convenient and less time- consuming to administer Ribavi n is the only drug available, with only moderate efficacy Antibacterial activity The aromatic guanylhydrazones of the present invention exhibit beside their excellent antiviral activity in addition excellent antibacterial activity Therefore, the present invention relates also to aromatic guanylhydrazones, their use as pharmaceutically active agents which exhibit antibacterial activity against Gram negative and Gram positive bacteria and their use as antibiotics in order to prevent or treat infections and diseases caused by Gram negative or Gram positive bacteria Antibiotics (Greek anti against, bios "life") are chemical compounds used to kill or inhibit the growth of infectious organisms Originally the term antibiotic referred only to organic compounds, produced by bacteria or molds, that are toxic to other microorganisms The term is now used loosely to include synthetic and semisynthetic organic compounds Antibiotic refers generally to antibactenals which comprise, for instance antimalaπais, antivirals, or antiprotozoals All antibiotics share the property of selective toxicity They are more toxic to an invading organism than they are to an animal or human host Penicillin is the most well-known antibiotic and has been used to fight many infectious diseases, including syphilis gonorrhea tetanus, and scarlet fever Another antibiotic streptomycin has been used to combat tuberculosis Although the mechanisms of antibiotic action were not scientifically understood until the late 20th century, the principle of using organic compounds to fight infection has been known since ancient times The first antibiotic to be used successfully in the treatment of human disease was tyrothncin, isolated from certain soil bacteria by American bacteriologist in 1939. Other antibiotics produced by a group of soil bacteria called actinomycetes have proved more successful One of these is streptomycin The drugs typically retard bacterial proliferation by entering the microbes and interfering with the production of components needed to form new bacterial cells For instance, the antibiotic tetracychne binds to πbosomes (internal structures that make new proteins) and, in so doing, impairs protein manufacture; penicillin and vancomycm impede proper synthesis of the bacterial cell wall. Antibiotics can be classified in several ways. The most common method classifies them according to their action against the infecting organism. Some antibiotics attack the ceil wall, some disrupt the cell membrane, and the majority inhibit the synthesis of nucleic acids and proteins, the polymers that make up the bacterial cell. Another method classifies antibiotics according to which bacterial strains they affect: staphylococcus, streptococcus, or Escheπchia coli, for example. Antibiotics are also classified on the basis of chemical structure, as penicillins, cephalosponns, aminoglycosides, tetracyc nes, macrolides, or sulfonamides, among others. Most antibiotics act by selectively interfering with the synthesis of one of the large- molecule constituents of the cell, the cell wall, or proteins or nucleic acids. Some, however, act by disrupting the cell membrane Some clinically useful drugs interfere with the synthesis of peptidoglycan, the most important component of the cell wall These drugs include the lactam antibiotics, which are classified according to chemical structure into penicillins, cephalosponns, and carbapenems. All these antibiotics contain a lactam ring as a critical part of their chemical structure, and they inhibit synthesis of peptidoglycan, an essential part of the cell wall They do not interfere with the synthesis of other intracellular components The continuing buildup of materials inside the cell exerts ever greater pressure on the membrane which is no longer properly supported by peptidoglycan The membrane gives way, the cell contents leak out, and the bacterium dies These antibiotics do not affect human cells because human cells do not have cell walls Many antibiotics operate by inhibiting the synthesis of various intracellular bacterial molecules, including DNA, RNA, ribosomes and proteins The synthetic sulfonamides are among the antibiotics that indirectly interfere with nucleic acid synthesis Nucleic acid synthesis can also be stopped by antibiotics that inhibit the enzymes that assemble these polymers, for example, DNA polymerase or RNA polymerase Examples of such antibiotics are actinomycin nfamicin, and πfampicin the last two being particularly valuable in the treatment of tuberculosis The quinolone antibiotics inhibit synthesis of an enzyme responsible for the coiling and uncoiling of the chromosome, a process necessary for DNA replication and for transcription to messenger RNA Some antibactenals affect the assembly of messenger RNA, thus causing its genetic message to be garbled When these faulty messages are translated, the protein products are nonfunctional There are also other mechanisms The tetracychnes compete with incoming transfer-RNA molecules, the aminoglycosides cause the genetic message to be misread and a defective protein to be produced, chloramphenicol prevents the linking of ammo acids to the growing protein and puromycm causes the protein chain to terminate prematurely releasing an incomplete protein Antibiotics may also be classed as bactericidal (killing bacteria) or bactenostatic (stopping bacterial growth and multiplication) Bactenostatic drugs are nonetheless effective because bacteria that are prevented from growing will die off after a time or be killed by the defense mechanisms of the host The tetracychnes and the sulfonamides are among the bactenostatic antibiotics Antibiotics that damage the cell membrane cause the cell's metabolites to leak out thus killing the organism Such compounds, including penicillins and cephalosponns, are therefore classed as bactericidal Antibiotics like these are wildly used pharmaceutical agents In 1954 two million pounds were produced in the U S A and today the amount exceeds 50 million pounds Human treatment accounts for roughly half the antibiotics consumed every year in the U S A If there are so many methods by which antibiotics may inhibit or kill microorganisms, the microorganisms have developed different strategies to avoid destruction by antibiotics These strategies comprise inactivation of the antibiotics, impermeability of microorganism s cell membrane or changes in the target structures of the antibiotics Bacteria might also eliminate entry ports for the drugs or, more effectively, may manufacture pumps that export antibiotics before the medicines have a chance to find their intracellular targets Inactivation means destruction of the antibiotic before it can reach its target in the microorganism Certain resistance genes ward off destruction by giving rise to enzymes that degrade antibiotics or that chemically modify, and so inactivate, the drugs Thus, microorganism are able to synthesize specific enzymes which can degrade by various biochemical processes different classes of antibiotics (e g , beta-lactamases, aminoglycoside-modifying enzymes, chloramphenicol acetyl transferase) Beta-lactamases are enzymes that destroy penicillins, cephalosponns, and other beta-lactam antibiotics via hydrolysis of the beta-lactam ring Gram-negative bacteria as well as Gram-positive bacteria may export beta- lactamases However, as Gram-negative bacteria have an inner and outer cell membrane the enzymes may also exist in the space between the membranes (the peπplasmic space) Here they may destroy beta-lactam molecules or according to one theory act as a nonhydrolytic barrier which "traps" some beta-lactam antibiotics even though they do not destroy them Impermeability refers to alterations in cell membrane composition or in specific membrane structures whereby the entering of antibiotics is prevented An excellent example are the "poπn" proteins of Gram-negative bacteria These form channels through which nutrients and potentially antibiotics enter the cell Alterations in the ponns may prevent certain antibiotics from penetrating and thus confer resistance on the cell Change in target structures means that microorganisms may also prevent antibiotics from being effective even if they enter the cell by changing the target structures of the antibiotics within the microorganism. Some resistance genes cause bacteria to alter or replace molecules that are normally bound by an antibiotic, changes that essentially eliminate the drug's targets in bacterial cells. Changes in penicillin-binding proteins (altered PBP's) which are a common cause of beta-lactam resistance in both Gram positive and Gram negative bacteria is a good example to explain this resistance strategy. Bacteria can acquire resistance genes through a few routes. Many inherit the genes from their forerunners. Other times, genetic mutations, which occur readily in bacteria, will spontaneously produce a new resistance trait or will strengthen an existing one. And frequently, bacteria will gain a defense against an antibiotic by taking up resistance genes from other bacterial cells in the vicinity. Indeed, the exchange of genes is so pervasive that the entire bacterial world can be thought of as one huge multicellular organism in which the cells interchange their genes with ease. Furthermore, resistance may be promoted by the antibiotics themselves during a selection process of the bacteria. The selection process is fairly straightforward. When an antibiotic attacks a group of bacteria, cells that are highly susceptible to the medicine will die. But cells that have some resistance from the start, or that acquire it later (through mutation or gene exchange), may survive, especially, if too little drug is given to overwhelm the cells that are present. Those cells, facing reduced competition from susceptible bacteria, will then go on to proliferate. When confronted with an antibiotic, the most resistant cells in a group will inevitably outcompete all others. Worldwide, many strains of S. aureus are already resistant to all antibiotics except vancomycin. Emergence of forms lacking sensitivity to vancomycin signifies that variants untreatable by every known antibiotic are on their way. Vancomycin is an antibiotic that interferes with cell wall formation of the microorganisms whereby limitations of cost and toxicity during application must be taken into account. S. aureus, a major cause of hospital-acquired infections, has thus moved one step closer to becoming an unstoppable killer. Moreover, administration of vancomycin over the years has turned E. faecalis into a dangerous reservoir of vancomycin-resistance traits. Recall that some strains of the pathogen S. aureus are multidrug-resistant and are responsive only to vancomycin. Because vancomycin-resistant E. faecalis has become quite common, public health experts fear that it will soon deliver strong vancomycin resistance to those S. aureus strains, making them incurable. The bystander effect has also enabled multidrug-resistant strains of Acinetobacter and Xanthomonas to emerge and become agents of potentially fatal blood-borne infections in hospitalized patients. By now, strains of at least three bacterial species like Enterococcus faecalis, Mycobacterium tuberculosis and Pseudomonas aeruginosa, capable of causing life-threatening illnesses already evade every antibiotic in the clinician's armamentarium, a stockpile of more than 100 drugs. In part because of the rise in resistance to antibiotics, the death rates for some communicable diseases (such as tuberculosis) have started to rise again, after having declined in the industrial nations. Therefore, new antibiotics are highly needed. Thus, object of the present invention is to provide new pharmaceutically active agents which can be used as a novel class of antibiotics. This object is solved by the disclosure of the independent claims. Further advantageous features, aspects and details of the invention are evident from the dependent claims, the description, the examples and the figure of the present application.

The compounds of the general formula (II) exhibit three of the characteristic structural elements as shown in the general formula (I), comprising a benzene core substituted with one or two residues characterized as X and one linker (characterized as Z) represented by an alkyl chain consisting of 1 to 6 methylene units connected to said benzene core via the structural element A as shown in formula (II). A further aspect of the present invention relates to the use of the aromatic guanylhydrazone compounds of the general formula (I) and/or (II) and/or pharmaceutically acceptable salts thereof as an inhibitor of deoxyhypusine synthase. Furthermore, another aspect of the present invention is directed to the use of a compound of the general formula (I) and/or (II) and/or pharmaceutically acceptable salts thereof as an inhibitor of nuclear transport or export in infectious diseases. Surprisingly, it was found that the inventive guanylhydrazone compounds of the general formula (I) and (II) exhibit excellent activity against various viruses and can therefore be used for prophylaxis and treatment of virally induced infections, including opportunistic infections, and also diseases associated with such infections. The compounds of the present invention and/or pharmaceutically active salts thereof can be used for the manufacture of an agent for prophylaxis and/or treatment of diseases and infections, including opportunistic infections, caused by viruses. Examples for such viruses are retroviruses (lentiviruses and oncoretroviruses), adenoviruses, hepadnaviruses, herpesviruses, influenza viruses and paramyxoviruses. Viruses which integrate in the genome of a cell are retroviruses, hepadnaviruses, adenoviruses, herpesviruses and influenza viruses while paramyxoviruses do not integrate in the genome of a cell are. The retroviruses may be selected from the group comprising lentiviruses and oncoretroviruses. Examples for lentiviruses are FIV, SIV, BIV, HIV-1 , HIV-2, visna virus, caprine arthritis-encephalitis virus (CAEV), and equine infectious anemia virus (EIAV). Most preferably, the retrovirus represents the lentivirus HIV-1 or HIV-2. HTLV-I, HTLV-II and BLV belong to the oncoretroviruses. Furthermore, the excellent antiviral activity of the inventive guanylhydrazone compounds can perferably be used to treat retroviruses wherein the retrovirus is a T-cell tropic HIV strain or wherein the retrovirus is a macrophage-tropic HIV strain. Paramyxoviruses comprise respiratory syncytial virus, parainfluenza viruses, mumps virus, and measles virus. More preferably, the paramyxovirus is respiratory syncytial virus. The herpesvirus family comprises the human herpesviruses 1 to 8 and different herpes viruses for various animal species as shown below in table 2: Table 2: Members of the herpesvirus family Subfamily Genus Human Animal α-herpesvirus simplex virus human herpesvirus 1 bovine herpesvirus 2 (herpes simplex virus 1 ) human herpesvirus 2 cercopithecine herpes¬ (herpes simplex virus 2) virus 1 , (herpes B virus) varicella virus human herpesvirus 3 pseudorabiesvirus (Varicella Zoster virus) bovine herpesvirus 1 equine-abortion virus β-herpesvirus cytomegalovirus human herpesvirus 5 (HCMV) muromegalovirus murine herpesvirus 1 roseolovirus human herpesvirus 6, aotine herpesvirus 1 , 3 human herpesvirus 7 γ-herpesvirus lymphocrytovirus human herpesvirus 4 cercopithecine herpes¬ (Epstein-Barr virus) virus 2 pongine herpesvirus 1 rhadinovirus human herpesvirus 8 ateline herpesvirus 2 saimirine herpesvirus 1 More preferably, the herpesvirus is selected from Herpes simplex virus I, Herpes simplex virus II, Varicella Zoster virus, Epstein-Barr virus, HCMV, or HHV8. The hepadnavirus are selected from HBV, Ground-Squirrel-Hepatitis virus (GSHV), or Woodchuck hepatitis virus (WHV). The HIV is according to Gallo and Barre-Sinoussi the causative agent of the acquired immune deficiency syndrome (AIDS) (Barre-Sinoussi et al., 1983; Gallo et al., 1984). In humans, HIV infection leads to development of immune incompetence, opportunistic infections, neurological disorders like cognitive and motor impairment, neoplastic growth, and death. HIV infection is pandemic and HIV associated diseases represent a major, increasing world health problem. Considerable effort is being put into the design of effective therapeutics, but no curative anti-retroviral drugs against AIDS exist. Therefore, design and testing of effective, non-toxic, novel anti-retroviral drugs with novel modes of action are still needed. The excellent antiviral activity of the aromatic guanylhydrazones of formula (I) allow their use for treating viruses resistant against the common antiviral drugs. Especially, the inventive guanylhydrazone compounds represent a new class of anti- retroviral drugs. The HIV is a complex retrovirus encoding in addition to the structural proteins gag, pol, and env several regulatory genes (Cullen 1991 ). Specifically, the trans-acting regulator of viral gene expression, called Rev, is crucially important for HIV replication (Feinberg et al., 1986). The HIV Rev protein is a nuclear phosphoprotein accumulating at steady state in the nucleoli and has the capacity to shuttle between the nuclear and cytoplasmic compartments (Meyer & Malim, 1994). Within the Rev protein distinct biological domains exist that are essential for its biological activity. The cis-acting target for Rev is a highly structured sequence element termed the Rev Response Element (RRE) located on HIV RNA (Malim et al.,1989). Upon binding to the HIV RNA as a monomer, Rev has to multimerize and subsequently interact with cellularly encoded cofactors (Malim et al., 1989) on its way to export the HIV RNA from the nucleus to the cytoplasm where protein translation occurs To date, Rev is the most studied specific RNA export factor containing a leucine-nch nuclear export signal (NES) (Pollard &Malιm, 1998) It was shown that the eukaryotic initiaton factor 5A (elF-5A) directly and specifically binds the HIV Rev NES (Ruhl et al 1993) Distinct elF-5A mutants have been shown to inhibit nuclear export of Rev proteins and, thereby, HIV replication (Bevec et al , 1996, Junker et al 1996) Moreover, anti elF-5A antibodies specifically block the nucleocytoplasmic translocation of Rev (Schatz et al , 1998), indicating that elF-5A is part of a specific nucleocytoplasmic export pathway utilized by HIV (Elfgang et al , 1999) In general the translocation of mRNAs across the nuclear pore requires a protein carrier, which is part of a complex system located in the nuclear envelope In this view, elF-5A would be a part of a transport system which is involved in the translocation of nuclear RNA to the cytoplasm After transit through the nuclear pores and assembly of translation-competent πbosomes, the preferentially translocated mRNAs would be utilized in the process of protein synthesis Therefore, small molecular weight chemical substances that interfere with the biological function of the elF-5A protein at the level of nuclear transport are potential antiviral compounds by interfering with nucleocytoplasmic translocation of viral mRNAs, especially in the field of HIV associated diseases Surprisingly, it was found that the aromatic guanylhydrazone compounds of the present invention act as an inhibitor of elF-5A activation The elF-5A protein has an unique biochemical feature in that it is the only eukaryotic cellular protein known containing the unusual am o acid hypusme Hypusine formation is a modification of the lysine residue at ammo acid position 50 within the 154 am o acids containing elF-5A precursor molecule by a two-step posttranslational enzymatic reaction (Park et al , 1993) In the first step the cellular enzyme deoxyhypusine synthase (DHS) catalyzes the transfer of an aminobutyl- moiety from spermidine to the lysine 50 within elF-5A via an enzyme-substrate intermediate formation at lysine 329 of the DHS to generate the elF-5A deoxyhypusine form (Wolff et al , 1997) This elF-5A deoxyhypusine intermediate is subsequently hydroxylated by the enzyme deoxyhypusine hydroxylase resulting in biologically active hypus e-containing elF-5A Hypusine formation is essential for the biological activity of the elF-5A protein (Park et al., 1993). In addition, biologically active elF-5A protein is essential for nuclear export of Rev proteins and, thereby, HIV replication (Bevec et al., 1996; Junker et al., 1996), as well as for the function of the Human T-cell leukemia virus type I (HTLV-I) Rex protein which is itself crucial for HTLV-I replication (Katahira et al., 1995). Therefore, an in vitro DHS screening assay was established (Bevec et al., 1996) in order to identify small molecular weight chemical substances as inhibitors of hypusine formation on the elF-5A protein with the goal to ultimately interfere with HIV and HTLV-I replication. In addition, such inhibitors may interfere with the replication of influenza viruses (targeting the biological activities of NS1 , NS2, or M1 proteins), with the replication of herpes viruses (targeting the biological activities of the Epstein-Barr Virus SM protein and the Herpes simplex virus ICP27 protein), or with the replication of adenoviruses (targeting the biological activities of E1B and E4orf6 proteins). Surprisingly it was found that the inventive aromatic guanylhydrazones and pharmaceutically acceptable salts thereof are potent inhibitors of elF-5A activation which exhibit their effect at pharmaceutically acceptable concentrations. Further, the aromatic guanylhydrazones are capable of inhibiting nuclear transport of RNA molecules. Without wishing to be bound to a theory, Applicant believes that particularly the RNA polymerase Ill-like export of mRNA molecules (mRNA molecules are usually believed to be exported from the nucleus to the cytoplasma by the RNA polymerase ll-dependent export pathways) from the nucleus to the cytoplasm of a cell may be inhibited. The inhibition of the nuclear transport represents a novel target for prevention or treatment of viral diseases, particularly HIV and opportunistic infections associated therewith. Employing the in vitro DHS screening assay (Bevec et al., 1996) small molecular weight compounds from the class of the inventive aromatic guanylhydrazones like N,N'-bis(3,5-diacetylphenyl)-decane diamide tetrakis(amidinohydrazone) (Compound 4: also known as N,N'-bis[3,5-bis[1-(aminoiminomethyl) hydrazono] ethyl] phenyl decane diamide). compound 1 , compound 5 were discovered as potent inhibitors of the hypusine formation on the elF-5A protein in submicromolar and low micromolar concentration ranges, respectively. Testing of compounds of the general formula (I) in relevant HIV cellular systems revealed that these compounds are potent inhibitors of HIV replication in the submicromolar and low micromolar range. Thus another aspect of the present invention is directed to the use of the compounds of the general formula (I) and/or pharmaceutically active salts as inhibitors of elF-5A activation and HIV replication. Further testing of these inventive compounds in relevant cellular systems revealed that they are also potent inhibitors of TNFα mRNA nuclear export. In addition thereto, it was surprisingly found that the compounds of the general formula (I) and/or (II) and/or pharmaceutically acceptable salts thereof act as inhibitors of nuclear export of TNF-α mRNA in TNF-α mediated diseases induced by bacteria and bacterial infections, respectively. Surprisingly, in relevant HIV cellular systems compound No. 4 was discovered as potent inhibitor of HIV replication in the submicromolar range on an aggressive T- cell-tropic HIV strain, on an aggressive macrophage-tropic HIV strain, on primary HIV isolates from patients, as well as on an aggressive multidrug-resistant HIV strain without apparent cellular toxicities at effective antiviral dosages. Hence, compound No. 4 is a potent nuclear export inhibitor interfering with HIV replication. The present invention therefore provides a genus of guanylhydrazone-substituted compounds that are useful as inhibitors of HIV-1 , HIV-2, HTLV-I as well as for treating diseases associated with those viruses. The compounds of the present invention act as inhibitors of deoxyhypusine synthase and also as inhibitors of elF-5A activation and HIV replication. Thus, a further aspect of the present invention is related to a method for inhibiting deoxyhypusine synthase activity for the prevention or treatment of infectious diseases, particularly viral infections, comprising administering a subject in need thereof a pharmaceutically effective amount of at least one compound of the general formula (I) and/or (II) and/or pharmaceutically active salts thereof. Since elF-5A is involved in the nuclear transport, the compounds of the present invention act as modulators of nuclear transport, particularly nuclear transport of RNA molecules More particularly, the compounds of the inventions may be used for the manufacture of an agent capable of inhibiting the export of RNA molecules from the nucleus to the cytoplasm of a cell, which may be an infected mammalian cell, e g a human, bovine equine, feline, caprine or ovine cell Preferably, the compounds of formula (I) are inhibitors of the export of viral RNA molecules from the nucleus to the cytoplasm More preferably, the compounds inhibit the export of RNA molecules which are derived from viral genetic material integrated in the genome of a host cell Furthermore, it is preferred that the compounds (I) and/or (II) are used as modulators of RNA polymerase III dependent export of RNA molecules Thus, another aspect of the present invention relates to the use of at least one aromatic guanylhydrazone compound of the general formula (I) and/or pharmaceutically active salts thereof for the manufacture of an agent capable of modulating RNA polymerase Ill-like export of RNA molecules from the nucleus to the cytoplasma of a cell Preferably said cell is a human cell By identifying the cellular targets of the compounds of formula (I) and/or (II) an agent for the prevention or treatment of infectious diseases involving nuclear export, particularly export of heterologous RNA from the nucleus to the cytoplasm via elF- 5A is provided Particularly the present invention provides an agent and a method for the prevention or treatment of infectious diseases caused by viruses integrating and not integrating in the genome of a cell The virus may be selected from the retroviruses, particularly lentiviruses and oncoretroviruses (HTLV-BLV group), adenoviruses, hepadnaviruses herpesviruses and influenza viruses More particularly, the virus is a retrovirus which may be selected from lentiviruses such as HIV-1 , HIV-2 FIV, bovine immunodeficiency virus (BIV), simian immunodeficiency viruses (SIVs), visna Maedi virus (VMV), caprine arthritis-encephalitis virus (CAEV), equine infectious anemia virus (EIAV), or oncoretroviruses such as human T-cell leukemia virus I (HTLV-I) human T-cell leukemia virus II (HTLV-II) and bovine leukemia virus (BLV) Most preferably, the retrovirus is HIV-1 or HIV-2 and the herpesvirus is Herpes simplex virus I, Herpes simplex virus II Varicella Zoster virus, Epstein-Barr virus, HCMV or HHV8 The compounds of the present invention can also be used for the manufacture of an agent for prophylaxis and/or treatment of diseases and infections caused by viruses integrating or not integrating in the genome of a cell. Examples for viruses which do not integrate in the genome of a cell are paramyxoviruses. Paramyxoviruses comprise, for instance, parainfluenza viruses, mumps viruses, measles virus, and respiratory syncytial viruses. More preferably, the virus is respiratory syncytial virus. The present invention discloses also a method wherein the inventive guanylhydrazone compounds are used to treat viruses which are resistant against most common antiviral drugs. Thereby, the aromatic guanylhydrazones and/or pharmaceutically acceptable salts thereof are administered in a dosage corresponding to an effective concentration in the range of 0.01-10 μM. More preferably, the inventive compounds of the present invention are administered in a dosage corresponding to an effective concentration in the range of 0.1 -5 μM. Surprisingly, it was found that the inventive compounds of formula (I) and (II) are potent inhibitors of HIV replication in a submillimolar, especially submicromolar, range on aggressive T-cell tropic HIV strains, aggressive macrophage-tropic HIV strains, on primary HIV isolates from patents as well as on agressive multidrug- resistant HIV strains without apparent cellular toxicity at the effective antiviral dosage. These findings suggest that the mentioned compound class of aromatic guanylhydrazones has advantages over the currently used drugs in the treatment of HIV diseases, e.g. the Highly Active Antiretroviral Therapy (HAART), consisting of Nucleoside Analog Reverse Transcriptase Inhibitors (NRTIs), Non-Nucleoside Reverse Transcriptase Inhibitors (NNRTIs) and Protease Inhibitors (Pis). This therapy is accompanied by quick emergence of resistant viral strains. In some patients, replication of resistant HIV-1 leads to emergence of more virulent variants of HIV-1. which are associated with an accelerated loss of CD4+ cells and confer a significantly increased risk of disease progression and death (D'Aquila et al., 1995). Resistance emerges as a consequence of the selective pressure of incompletely suppressive therapy and is determined by mutations in the HIV reverse transcriptase and protease genes. Primary mutations alter the binding of the drug to its target resulting in an increase in the amount of drug necessary to inhibit the enzyme. Secondary mutations increase resistance by improving the fitness of viruses carrying primary infections. In the case of NRTIs, the mutation M148V is an example of a key mutation leading to high-level resistance. Additional positions of mutations include M41 L, K70R, T215Y (Zidovudine), L74V (Didanosine), T69D (Zalcitabine), Y115F (Abacavir). Multidrug resistance conferring cross-resistance to the entire NRTI class is well recognized (Q151 and insertion mutation T69SSS). Cross-resistance is also extensive among the three currently used NNRTIs Efavirenz, Nevirapine and Delavirdine which makes them inactive against the virus expressing the K103N mutation in the reverse transcriptase gene. The K103N mutation acts by inhibiting formation of the drug-binding pocket. For this class of drugs, the "first shot" is most frequently the "only shot". Also, cross-resistance between the Pis is rather a rule than an exception (Indinavir and Ritonavir have almost identical resistance patterns - K20M, V32I, M36I, M46I, I54V, L63P, A71V, V82A/T/F, I84V, L90M - and Saquinavir-resistant strains are also cross-resistant to other Pis - L10I, K20M, I84V, L90M) (Roberts et al., 1998). Even for the novel type of anti HIV drugs like T20, a 36 amino acid peptide derived from the HIVgp41 protein which inhibits fusion of the virus to the host cell, resistance has already been demonstrated in vitro (Kilby et al., 1998). In addition, patients on HAART face long- term side effects, including pancreatitis, peripheral neuropathies, hepatotoxicity, diabetes (Visnegarwala et al.,1997), or metabolic abnormalities in body fat redistribution (Gervasoni et al., 1999), as well as in the glucose metabolism and the cardiovascular field (Henry et al.,1998). For many patients, who experience the above mentioned drug toxicities, a structured treatment interruption is an unaviodable necessity ("Drug holidays"). However, during this time the suppressed virus may bounce back. Due to the proposed mode of action as inhibitors of the biological function of the cellular eiF-5A protein which per se is a crucial cofactor for the function of the essential viral protein Rev for the translocation of essential HIV mRNAs from the nucleus to the cytoplasm, aromatic guanylhydrazones and substituted aromatic guanylhydrazones are very likely to decrease the resistance formation in the viruses for two main reasons: 1.) The primary target is a cellular protein; 2.) The viral Rev- RRE interaction is highly conserved. Mutations in the Rev activation domain (the interaction site of REV with elF-5A protein) are proven medical intervention strategies for inhibiting HIV replication (Bevec et al., 1992; Malim et al., 1992; Liu et al., 1994; Escaich et al., 1995; Woffendin et al., 1996; Bonyhadi et al., 1997; A molecular genetic intervention for AIDS-effects of a transdominant negative form of REV - General Clinical Research Center, University of Michigan, Ann Arbor, Center Watch; Clinical Trials Listing Service on Medscape, January 7, 2000). Due to their reported ability to cross the blood-brain barrier in a rat animal model of permanent focal cortical ischemia (Meistrell et al., 1997) the inventive compounds of formula (I) belong to the few anti-HIV substances (like Glaxo Wellcome's Abacavir, Lamivudine, Zidovudine or GW42867X, Bristol-Myers Squibb's Stavudine, or Roxane Laboratories' Nevirapine) which may also inhibit HIV replication in the central nervous system (CNS) for prevention or treatment of HIV-induced CNS disorders. Usually, the PI inhibitors are shown not to cross the blood-brain-barrier. Due to their mode of action, it may be reasonably expected that the compounds of general formula (I) and (II) will also inhibit the replication of other viruses as stated above. In a related aspect to the studies disclosed herein, the present invention is directed to a method for treating virally induced diseases and infections, including opportunistic infections, in a mammal, including a human, which comprises administering to the mammal an amount of at least one compound of formula (I) and/or (II) and/or pharmaceutically acceptable salts thereof effective to treat virally induced infections and/or diseases. Preferably, said method is used for treating HIV-1 infections. Said virally induced diseases and infections may by cause by the viruses comprising retroviruses, adenoviruses, hepadnaviruses, herpesviruses, influenza viruses, and paramyxoviruses. Hepadnaviruses may be selected from the group comprising orthohepadnaviruses and avihepadnaviruses. Examples for orthohepadnaviruses are HBV. Ground- Squirrel-Hepatitis virus (GSHV) Woodchuck Hepatitis virus (WHV) Most preferably, the hepadnavirus represents the human Hepatitis B virus (HBV) Herpesviruses may be selected from the group comprising α-herpesviruses (Simplexvirus, Vancellavirus), β-herpesviruses (Cytomegalovirus also known as human herpesvirus 5, Muromegalovirus, Roseolovirus), or γ-herpesviruses (Lymphocryptovirus, Rhadinovirus) Examples for α-herpesviruses are Herpes simplex virus type 1 (human herpesvirus 1 ), Herpes simplex virus type 2 (human herpesvirus 2), Varicella Zoster virus (human herpesvirus 3) Examples for γ- herpesviruses are Epstein-Barr virus (human herpesvirus 4) or human herpesvirus type 8 (HHV8) More preferably, the herpesvirus is Herpes simplex virus type 1 , or Varicella Zoster virus, or Epstein-Barr virus (EBV), or human cytomegalovirus (HCMV), or human herpesvirus 6, or human herpesvirus 7, or human herpesvirus type 8 (HHV8) Most preferably, the herpesvirus represents the α-herpesviruses Herpes simplex virus type 1 , or Varicella Zoster virus, or the γ-herpesviruses Epstein-Barr virus, or Human Herpes virus type 8 Paramyxoviruses may be selected from the group comprising paramyxoviπnae or pneumoviπnae Most preferably, the paramyxovirus represents the respiratory syncytial virus (RSV) In addition thereto, a method of inhibiting nuclear exDOrt for the prevention or treatment of infectious diseases particularly viral infections comprising administering a subject in need thereof a pharmaceutically effective amount of at least one compound of the general formula (I) and/or pharmaceutically active salts thereof Said infectious diseases, such as HIV-1 infections, or Hepatitis B virus infections, or Herpes-simplex-Virus 1 infections or Epstein-Barr virus infections, or Human herpesvirus 8 infections, or Varicella-zoster virus infections, or Adenovirus infections or Respiratory syncytial virus infections, are, for instance, diseases caused by viruses, especially lentiviruses or oncoretroviruses hepadnaviruses, paramyxoviruses, adenoviruses, herpesviruses and influenza viruses More preferably, said diseases are caused by the lentiviruses HIV-1 or HIV-2 or by the hepadnavirus Hepatitis B virus.

Kindly remember the previous section titled "HIV & AIDS": AIDS (acquired immune deficiency syndrome) is a condition caused by HIV. This virus attacks the immune system, the body's "security force" that fights off infections. When the immune system breaks down "opportunistic infections" (Ols) take advantage of the body's weakened defenses. Therefore, to say that someone "died of AIDS" is not entirely accurate, since it is often the opportunistic infections that cause death. One diagnostic parameter to detect AIDS is to look at the patient's CD4+ cell counts. Another way to detect AIDS is to look for Ols: if an HIV+ individual is diagnosed with an opportunistic infection this will be taken as indication for AIDS. Thus, it is really important to develop new methods and to provide new pharmaceutically active compounds in order to prevent and treat said opportunistic infections. Listed below are lessons about each of the major Ols & cancers that can occur during late-stage HIV disease: Bacterial Infections • Mycobacterium Avium Complex (MAC, MAI) • Salmonellosis • Syphilis & Neurosyphilis • Tuberculosis (TB) Malignancies (Cancers) • Anal Dysplasia/Cancer • Cervical Dysplasia/Cancer • Kaposi's Sarcoma (KS) • Lymphomas Viral Infections Cytomegalovirus (CMV) • Hepatitis Herpes Simplex Virus (oral & genital herpes) Herpes Zoster Virus (shingles) Human Papiloma Virus (HPV, genital warts, anal/cervical dysplasia/cancer) • Molluscum Contagiosum Oral Hairy Leukoplakia (OHL) Progressive Multifocal Leukoencephalopathy (PML) Fungal Infections • Aspergillosis • Candidiasis (thrush, yeast infection) • Coccidioidomycosis • Cryptococcal Meningitis • Histoplasmosis Protozoal infections • Cryptosporidiosis • Microsporidiosis • Pneumocystis Carinii Pneumonia (PCP) • Toxoplasmosis Neurological Conditions • AIDS Dementia Complex • Peripheral Neuropathy Other Conditions and Complications • Apthous Ulcers • Depression & Anxiety • Fatigue and Anemia • Nausea & Diarrhea • Thrombocytopenia • Wasting Syndrome & Lipodystrophy The past ten years of study have produced clear evidence that individuals with HIV-1 infection are at risk for both primary and secondary neurological and neurobehavioral disorders. Primary disorders occur as a result of the influence of HIV-1 on the central nervous system (CNS); whereas, secondary disorders usually occur as a result of immune system deficiencies or treatment effects. Neurobehavioral disorders associated with HIV-1 infection may be complicated by preexisting or new onset psychological and emotional disorders. Clinical research in neurological, and particularly neurobehavioral disorders associated with HIV-1 infection has been complicated by methodological issues and controversies as well as ill-defined nosology. In the following information from current research on HIV-1 related neurological disorders, diagnosis, and treatment with focus on the AIDS related neurobehavioral disorders and a brief review of secondary HIV-related neurological disorders are presented. The inventive guanylhydrazone compounds of the present invention are also useful for prophylaxis and/or treatment of the opportunistic diseases described below. HIV-1 Related Neurological and Neurobehavioral Disorders Primary Disorders HIV-1 can directly invade the central nervous system (CNS). Viral infection in the CNS is most often seen in mono-nuclear microglial cells and multi-nucleated giant cells. Neuronal loss is usually secondary to the presence of HIV-1 in surrounding cells and not in the neurons themselves. The process by which neuronal death occurs is speculative, although proposed mechanisms include the production of cytokines that interfere with neuronal function, production of abnormal neurotransmitter metabolites that are neurotoxic, and the presence of certain viral fragments that interfere with neurotransmitter transmission. HIV-1 associated CNS disorders include the neurobehavioral disorders, HIV associated minor cognitive disorder and HIV associated dementia, and the neurological disorder, HIV associated myelopathy. HIV Associated Minor Cognitive Disorder HIV associated minor cognitive disorder may occur in patients who are otherwise asymptomatic or mildly symptomatic. The disorder is characterized by subcortical deficits of attention, information processing speed, learning and memory, and psychomotor skills. HIV associated minor cognitive disorder may be complicated by the presence of depression or anxiety, but is not caused by psychiatric problems. Recent studies have shown that the presence of HIV associated minor cognitive disorder increases with worsening immune function. CD4 and CD8 lymphocyte counts, CD4/CD8 ratios, and the presence of beta-2 microglobulin (B2M) in both serum and cerebrospinal fluid have been shown to correlate with severity of HIV associated cognitive disorder. However, they are not pathognomonic for the disorder. HIV Associated Dementia HIV associated dementia (HAD) is a progressive disorder that initially presents as apathy, inertia, cognitive slowing, memory loss, and social withdrawal. As it progresses, multiple cognitive functions become increasingly impaired. The terminal phases are characterized by global cognitive impairment, mutism, and severe psychomotor retardation. Unlike HIV associated minor cognitive disorder, HAD rarely develops prior to constitutional problems and usually does not develop prior to other AIDS defining illnesses. As with HIV associated minor cognitive disorder, thorough neuropsychological evaluation is recommended to assist in differential diagnosis and to identify the presence of any co-existing psychiatric disturbance. HIV Associated Myelopathy HIV associated myelopathy is characterized by symptoms of weakness, incoordination, and/or urinary incontinence and signs of paresis, spasticity, and hyperreflexia. This condition affects approximately 20% of adult patient with AIDS, although evidence of myelopathy is found at autopsy in 50% of patients. This condition is often associated with co-existing cognitive dysfunction. HIV-1 has been found in the spinal cord and CSF of patients with HIV associated myelopathy; however, it is uncertain whether HIV-1 is a direct pathogen. Other conditions such as vitamin B12 deficiencies cause similar disorders, particularly in the immune-compromised patient. Secondary Disorders The immuno-compromised HIV patient is at risk for numerous peripheral and central nervous system disorders that are not caused directly by the HIV virus. Peripheral nerve disorders, including sensory neuropathy, inflammatory demyelinating polyneuropathies, mononeuropathies, and cranial neuropathies are found in HIV infected patients. The incidence of neuropathies increases with worsening immune system functioning and usually occur in the presence of other HIV related disorders; however, in rare instances, peripheral neuropathies may precede other HIV symptoms. HIV-1 associated myopathy is uncommon, but may present across all stages of disease. Immune compromised patients are at risk for neurological opportunistic infections. Cryptococcal meningitis, toxoplasmosis, cytomegalovirus (CMV), and progressive multifocal leukoencephalopathy (PML) are seen in varying incidences among AIDS patients. CMV retinitis causes a hemorrhagic retinitis in up to 20% of AIDS patients. The treatment of choice is ganciclorvir, which has demonstrated a positive clinical response in approximately 80% of patients treated. In addition to the opportunistic infections, AIDS patients are at risk for opportunistic CNS neoplasms, metabolic encephalopathies, cerebrovascular disease, and neurosyphilis.

The free base forms differ from their corresponding salt forms somewhat in certain physical properties, such as solubility in polar solvents, but the salts are otherwise equivalent to their corresponding free base forms for purposes of this invention. In relation to the above disclosed use of the compounds of the general formula (I) and (II) another aspect of the present invention is directed to the use of at least one inventive compound of formula (I) and/or (II) and/or pharmaceutically acceptable salts thereof for prophylaxis and/or treatment of infections and diseases, including opportunistic infections, caused by Gram positive or Gram negative bacteria. Preferably, caused by Gram positive bacteria. The inventive guanylhydrazones of the general formula (I) and/or (II) and/or pharmaceutically acceptable salts thereof may also be used for the manufacture of a pharmaceutical formulation for prophylaxis and/or treatment of infections and diseases caused by Gram negative or Gram positive bacteria, preferably by Gram negative bacteria. Gram positive and Gram negative bacteria may be distinguished by differential staining. In some species of bacteria the cell wall consists primarily of a thick layer of peptidoglycan. Other species have a much thinner layer of peptidoglycan and an outer as well as an inner membrane. When bacteria are subjected to Gram's stain, these differences in structure affect the differential staining of the bacteria with a dye called gentian violet. The differences in staining coloration (Gram positive bacteria appear purple and Gram negative bacteria appear colorless or reddish, depending on the process used) are the basis of the classification of bacteria into Gram positive (those with thick peptidoglycan) and Gram negative (those with thin peptidoglycan and an outer membrane), because the staining properties correlate with many other bacterial properties. As mentioned above the inventive compounds of the general formulas (I) and (II) can be used as antibiotics in order to treat infections and/or diseases caused by Gram negative or Gram positive bacteria. Thus, the inventive aromatic guanylhydrazone compounds are useful to treat diseases caused by bacteria. Diseases caused by bacteria may comprise, but are not limited to, borreliosis, syphilis, morbus Weil, enteritis, endocarditis, sinusitis, otitis media, brucellosis, encephalitis, typhus, paratyphus, dysenteria, yersinia-pestis-infection, lymphadenitis, cholera, hospitalization-caused-diseases, granuloma inguinale, CNS necrosis, rickettsiosis, Oroya fever, angiomatosis and conjunctivitis.

Also preferred is the administration of the inventive guanylhydrazone compounds in combination with further therapeutic agents, especially other antibacterial agents, such as antibiotics. Pharmaceutical Compositions A still further aspect of the present invention relates to pharmaceutical compositions comprising at least one compound of the general formulas (I) and/or (II) and/or pharmaceutically acceptable salts thereof as an active ingredient and a pharmaceutically acceptable carrier, excipient, adjuvent and/or diluent. The compounds of the general formulas (I) and/or (II) can also be administered in form of their pharmaceutically active salts optionally using substantially nontoxic pharmaceutically acceptable carrier, excipients, adjuvents or diluents. The medications of the present invention are prepared in a conventional solid or liquid carrier or diluent and a conventional pharmaceutically-made adjuvant at suitable dosage level in a known way. The preferred preparations are in administratable form which is suitable for oral application. These administratable forms, for example, include pills, tablets, film tablets, coated tablets, capsules, powders and deposits. Other than oral adminisratable forms are also possible. The inventive guanylhydrazone compounds of the general formulas (I) and/or (II) or pharmaceutical preparations containing said compounds may be administed by any appropriate means, including but not limited to injection (intravenous, intraperitoneal, intramuscular, subcutaneous) by absorption through epithelial or mucocutaneous linings (oral mucosa, rectal and vaginal epithelial linings, nasopharyngial mucosa, intestinal mucosa); orally, rectally, transdermally, topically, intradermally, intragastrally, intracutanly, intravaginally, intravasally, intranasally, intrabuccally, percutanly, sublingually, or any other means available within the pharmaceutical arts. Within the disclosed methods the pharmaceutical compositions of the present invention, containing at least one aromatic guanylhydrazone compound of the general formula (I) or pharmaceutically acceptable salts thereof as an active ingredient will typically be administered in admixture with suitable carrier materials suitably selected with respect to the intended form of administration, i.e. oral tablets, capsules (either solid-filled, semi-solid filled or liquid filled), powders for constitution, oral gels, elixirs, dispersible granules, syrups, suspensions, and the like, and consistent with conventional pharmaceutical practices. For example, for oral administration in the form of tablets or capsules, the active drug component may be combined with any oral nontoxic pharmaceutically acceptable inert carrier, such as lactose, starch, sucrose, cellulose, magnesium stearate, dicalcium phosphate, calcium sulfate, talc, mannitol, ethyl alcohol (liquid forms) and the like. Moreover, when desired or needed, suitable binders, lubricants, disintegrating agents and coloring agents may also be incorporated in the mixture. Powders and tablets may be comprised of from about 5 to about 95 percent inventive composition. Suitable binders include starch, gelatin, natural sugars, corn sweeteners, natural and synthetic gums such as acacia, sodium alginate, carboxymethyl-cellulose, polyethylene glycol and waxes. Among the lubricants there may be mentioned for use in these dosage forms, boric acid, sodium benzoate, sodium acetate, sodium chloride, and the like. Disintegrants include starch, methylceliulose, guar gum and the like. Sweetening and flavoring agents and preservatives may also be included where appropriate. Some of the terms noted above, namely disintegrants, diluents, lubricants, binders and the like, are discussed in more detail below. Additionally, the compositions of the present invention may be formulated in sustained release form to provide the rate controlled release of any one or more of the components or active ingredients to optimize the therapeutic effects, i.e. antihistaminic activity and the like. Suitable dosage forms for sustained release include layered tablets containing layers of varying disintegration rates or controlled release polymeric matrices impregnated with the active components and shaped in tablet form or capsules containing such impregnated or encapsulated porous polymeric matrices. Liquid form preparations include solutions, suspensions and emulsions. As an example may be mentioned water or water-propylene glycol solutions for parenteral injections or addition of sweeteners and opacifiers for oral solutions, suspensions and emulsions. Liquid form preparations may also include solutions for intranasal administration. Aerosol preparations suitable for inhalation may include solutions and solids in powder form, which may be in combination with a pharmaceutically acceptable carrier such as inert compressed gas, e.g. nitrogen. For preparing suppositories, a low melting wax such as a mixture of fatty acid glycerides such as cocoa butter is first melted, and the active ingredient is dispersed homogeneously therein by stirring or similar mixing. The molten homogeneous mixture is then poured into convenient sized molds, allowed to cool and thereby solidify. Also included are solid form preparations which are intended to be converted, shortly before use, to liquid form preparations for either oral or parenteral administration. Such liquid forms include solutions, suspensions and emulsions. The inventive aromatic guanylhydrazone compounds of the present invention may also be deliverable transdermally. The transdermal compositions may take the form of creams, lotions, aerosols and/or emulsions and can be included in a transdermal patch of the matrix or reservoir type as a re conventional in the art for this purpose. The term capsule refers to a special container or enclosure made of methyl cellulose, polyvinyl alcohols, or denatured gelatins or starch for holding or containing compositions comprising the active ingredients. Hard shell capsules are typically made of blends of relatively high gel strength bone and pork skin gelatins. The capsule itself may contain small amounts of dyes, opaquing agents, plasticizers and preservatives. Tablet means compressed or molded solid dosage form containing the active ingredients with suitable diluents. The tablet can be prepared by compression of mixtures or granulations obtained by wet granulation, dry granulation or by compaction well known to a person skilled in the art. Oral gels refers to the active ingredients dispersed or solubilized in a hydrophillic semi-solid matrix. Powders for constitution refers to powder blends containing the active ingredients and suitable diluents which can be suspended in water or juices. Suitable diluents are substances that usually make up the major portion of the composition or dosage form. Suitable diluents include sugars such as lactose, sucrose, mannitol and sorbitol, starches derived from wheat, corn rice and potato, and celluloses such as microcrystalline cellulose. The amount of diluent in the composition can range from about 5 to about 95% by weight of the total composition, preferably from about 25 to about 75%, more preferably from about 30 to about 60% by weight. The term disintegrants refers to materials added to the composition to help it break apart (disintegrate) and release the medicaments. Suitable disintegrants include starches, "cold water soluble" modified starches such as sodium carboxymethyl starch, natural and synthetic gums such as locust bean, karaya, guar, tragacanth and agar, cellulose derivatives such as methylcellulose and sodium carboxymethylcellulose, microcrystalline celluloses and cross-linked microcrystalline celluloses such as sodium croscarmellose, alginates such as alginic acid and sodium alginate, clays such as bentonites, and effervescent mixtures. The amount of disintegrant in the composition can range from about 2 to about 20% by weight of the composition, more preferably from about 5 to about 10% by weight. Binders characterize substances that bind or "glue" powders together and make them cohesive by forming granules, thus serving as the "adhesive" in the formulation. Binders add cohesive strength already available in the diluent or bulking agent. Suitable binders include sugars such as sucrose, starches derived from wheat, corn rice and potato; natural gums such as acacia, gelatin and tragacanth; derivatives of seaweed such as alginic acid, sodium alginate and ammonium calcium alginate; cellulosic materials such as methylcellulose and sodium carboxymethylcellulose and hydroxypropyi-methylcellulose; polyvinylpyrrolidone; and inorganics such as magnesium aluminum silicate. The amount of binder in the composition can range from about 2 to about 20% by weight of the composition, more preferably from about 3 to about 10% by weight, even more preferably from about 3 to about 6% by weight. Lubricant refers to a substance added to the dosage form to enable the tablet, granules, etc. after It has been compressed, to release from the mold or die by reducing friction or wear. Suitable lubricants include metallic stearates such as magnesium stearate, calcium stearate or potassium stearate; stearic acid; high melting point waxes; and water soluble lubricants such as sodium chloride, sodium benzoate, sodium acetate, sodium oleate, polyethylene glycols and d'l- leucine. Lubricants are usually added at the very last step before compression, since they must be present on the surfaces of the granules and in between them and the parts of the tablet press. The amount of lubricant in the composition can range from about 0.2 to about 5% by weight of the composition, preferably from about 0.5 to about 2%, more preferably from about 0.3 to about 1.5% by weight. Glidents are materials that prevent caking and improve the flow characteristics of granulations, so that flow is smooth and uniform. Suitable glidents include silicon dioxide and talc. The amount of glident in the composition can range from about 0.1 % to about 5% by weight of the total composition, preferably from about 0.5 to about 2% by weight. Coloring agents are excipients that provide coloration to the composition or the dosage form. Such excipients can include food grade dyes and food grade dyes adsorbed onto a suitable adsorbent such as clay or aluminum oxide. The amount of the coloring agent can vary from about 0.1 to about 5% by weight of the composition, preferably from about 0.1 to about 1 %. Techniques for the formulation and administration of the aromatic guanylhydrazone compounds of the present invention may be found in "Remington's Pharmaceutical Sciences" Mack Publishing Co., Easton PA. A suitable composition comprising at least one compound of the invention may be a solution of the compound in a suitable liquid pharmaceutical carrier or any other formulation such as tablets, pills, film tablets, coated tablets, dragees, capsules, powders and deposits, gels, syrups, slurries, suspensions, emulsions, and the like. A therapeutically effective dosage of a compound of the general formula (I) refers to that amount of the compound that results in an at least partial inhibition of bacterial cell growth. Toxicity and therapeutic efficacy of such compounds can be determined by standard pharmaceutical, pharmacological, and toxicological procedures in cell cultures or experimental animals for determining the LD50 (the dose lethal to 50% of the population) and the ED50 (the dose therapeutically effective in 50% of the population). The dose ratio between toxic and therapeutic effect is the therapeutic index and can be expressed as the ratio between LD50 and ED50. The dosage of the compound lies preferably within a range of circulating concentrations that include the ED50 with little or no toxicity. More preferably, the dosage of the compound corresponds to an effective concentration in the range of 0.01 -10μM. The actual amount of the composition administered will be dependent on the subject being treated, on the subject's weight, the severity of the affliction, the manner of administration and the judgement of the prescribing physician. Fig. 1 shows the structures of several aromatic guanylhydrazone compounds of the general formula (I): Compound 1 : N-(4-acetylphenyl)-N'-(3,5-diacetylphenyl)urea tris (amidinohydrazone) Compound 2: N,N'-bis (3-acetylphenyl) pentane diamide bis (amidinohydrazone) Compound 3: N,N'-bis (3,5-diacetylphenyl) pentane diamide tetrakis (amidinohydrazone) Compound 4: N,N'-bis (3,5-diacetylphenyl) decane diamide tetrakis (amidinohydrazone) Compound 5: N,N'-bis (3,5-diacetylphenyl) butane diamide tetrakis (amidinohydrazone) Compound 6: N,N'-bis (3,5-diacetylphenyl) hexane diamide tetrakis (amidinohydrazone) Compound 7: N,N'-bis (3,5-diacetylphenyl) heptane diamide tetrakis (amidinohydrazone) Compound 8: N,N'-bis (3,5-diacetylphenyl) isophthalic acid diamide tetrakis (amidinohydrazone) Examples Materials and Methods Cloning of the human elF-5A and DHS cDNA was achieved using a premade liver cDNA library (Clontech) with polymerase chain reaction (PCR) primers specific for elF-5A (Smit-McBride et at., 1989), and DHS (Bevec et al., 1996) cDNAs harbouring additional BamHI and EcoRI restriction sites for positional cloning into protein expression vectors pGex (Amersham Pharmacia Biotech). After sequence determination, the plasmids were transformed into the E. coli strain BL21 (DE3). An overnight bacterial culture was diluted 1 : 10 in fresh LB- medium (supplemented with 100 μg/ml ampicillin) and grown for 1 h at 37°C. Subsequently, IPTG was added (0.5 mM) and culture proceeded for a further 4h. The cells were pelleted and resuspended in 2 ml of PBS containing 1 mM DTT. After sonication (twice for 30s at a setting of 10W) the lysates was centrifuged for 2 min at 14,000 rpm in an Eppendorf centrifuge and the pellet dissolved in 1 ml of 8 M urea and dialysed overnight against 0.3 M glycine-NaOH (pH 9.0) / 0.1% Tween 20. The consistency of the fusion proteins was tested on a SDS-PAGE gel. After that, the GST-elF-5A fusion was cleaved with Factor Xa (Roche) due to the manufacturer ' s recommendation, whereas the GST-DHS fusion protein was tested for deoxyhypusine synthase activity. The standard enzymatic reaction mixture (total volume 200 μl) contained 5 μg elF-5A, 0.5 μCi [ 3 H]spermidine (15 Ci/mmol), 1 mM NAD + , 1 mM DTT and various quantities of GST-DHS in 0.3 M glycine-NaOH buffer, pH 9.0, supplemented with 50 μg/ml BSA. The mixture was incubated at 37°C for 3h and stopped by adding 100 μl of 20 mM spermidine in PBS. The reaction mixture was passed over Sephadex G-25 gel filtration columns (PD-10 columns, Amersham Pharmacia Biotech) in order to separate the labeled elF-5A from excess spermidine. The incorporated radioactivity was measured in a liquid scintillation counter. The [ 3 H]spermidine was obtained from DuPont-NEN; the unlabeled spermidine from Calbiochem, and NAD + from Roche. HIV Experiments HIV detection HIV replication was measured either by p24 HIV Antigen Capture Assay Kit (ELISA; HIVAG-1 Monoclonal kit B1A011 ; Abbott) following the manufacturer ' s recommendation, or by using the Quantiplex HIV-1 RNA 3.0 Assay (bDNA) system (Chiron Diagnostics). The latter assay is a signal amplification nucleic acid probe assay (employing a sandwich nucleic acid hybridization procedure) for direct quantitation of HIV RNA in human plasma. There, in brief, HIV-1 is first concentrated from plasma by centrifugation. After release of genomic HIV-1 RNA from the virions, the RNA is captured to a microwell by a set of specific, synthetic oligonucleotide capture probes. A set of target probes hybridize to both the viral RNA and the pre-amplifier probes. The capture probes, comprised of 17 individual capture extenders, and the target probes, comprised of 81 individual target extenders, bind to different regions of the pol gene of the viral RNA. The amplifier probe hybridizes to the pre-amplifier forming a branched DNA (bDNA) complex. Then, multiple copies of an alkaline phosphatase labeled probe are hybridized to this immobilized bDNA complex. Detection is achieved by incubating the entire complex with a chemoluminescent substrate. Light emission is directly proportional to the amount of HIV-1 RNA present in each sample, and results are recorded as relative light units by an appropriate analyzer. Cells and HIV strains Jurkat cells (species: human T-cell leukemia; special characteristics: cells are permissive for growth of T-cell tropic HIV strains; source:ATCC Cat.No.TIB 152) or PM1 cells (species: clonal derivative of human HUT 78 cells; special characteristics: cells are permissive for growth of macrophage-tropic and T-cell tropic HIV strains; source: Dr. Marvin Reitz, courtesy of the NIH AIDS Research and Reference Reagent Program Cat.No. 3038) were stimulated with Phytohemagglutinin (PHA-P, Product No. L9132 from Sigma) in a concentration of 2 μg/ml (1.5x10 6 cells/ml) and Hexadimethrine Bromide (Polybrene, Product No. H9268 from Sigma) in a concentration of 2 μg/ml (1.5 x 10 6 cells/ml) in RPMI 1640 medium containing 10 % fetal calf serum (FCS, Pansystems GmbH) and antibiotics for 3 days. For HIV-1 infection, 5x10 7 cells were resuspended in 500 μl culture medium without test drugs and incubated in a 50 ml blue-cap-tube at 37°C for 5 hrs with HIV-1 high titer viral stocks. Jurkat cells were infected with the T-cell tropic strain HIV-1 NL4-3, PM1 cells with the macrophage tropic strain HIV-1 Ba-L (both from the NIH AIDS Research and Reference Reagent Program). After infection, cells were washed twice with PBS without Ca 2+ and Mg 2+ to avoid false positive p24 antigen determination. Cells were resuspended, and identical aliquots (1x10 6 /ml) of infected cells were further cultured in 10 ml medium with test drugs at various concentrations, or in medium with DMSO as control for calculation of the inhibition of virus replication [in %]. Culture medium was changed and cells were split at days 3 and 7 of the experiments. Viability of the cells (Trypan-blue staining), cell counts and p24 antigen levels were determined at days 3, 7 and 10 of the experiments. No significant differences in cell viability were observed (-85-90 % living cells). Inhibition of T-cell-tropic and macrophage-tropic HIV-1, Results: PM1 cells de novo infected with macrophage-tropic HIV-1 Ba -L strain Jurkat cells de novo infected with T-cell-tropic HIV-1 NL4 3 strain At day 10 of infection, the HIV strains replicated vigorously in untreated cultures. Numbers describe percent inhibition of HIV replication as compared to control experiments. Peripheral blood mononuclear cells (PBMCs) from HIV-1 -infected patients were isolated - (after informal consent was given) - by Biocoll (Biochrom) gradient centrifugation. 1 x10 6 /ml PBMCs were cultured (5 ml in a six well 32-mm plate) in presence of the test drugs or in DMSO (control diluent) in RPMI 1640 medium supplemented with 10% autologous serum and 2 mM L-Glutamine at 37°C and 5% CO 2 . The culture medium was changed every 3 days during the experiments. Once a week, each culture was split 1 :1 and 2x10 6 feeder-PBMCs (per well) and recombinant Interleukm 2 (IL-2) [10U / ml] (Roche) was added. Prior to addition to the cell cultures, the feeder-PBMCs, prepared from 4 healthy donors, were treated for 4 days with PHA-P and PB (2 μg/ml each per 2x10 6 ceils). At day 14, viability of the PBMCs (Trypan-blue staining), cell count and virus load (p24 antigen: Innotest HIV Antigen mAb, Innogenetics N. V., Gent, Belgium, or bDNA: HIV-1 RNA 3.0 Assay, Bayer AG, Tarrytown, NY, USA) was determined. No significant differences in cell viability were observed (-75-80 % vital cells). Inhibition of clinical HIV-1 isolates, Results: HIV-infected PBMCs from patient 1 HIV-infected PBMCs from patient 2 HIV-infected PBMCs from patient 3 At day 14 of cultivation, the virus replicated vigorously in all untreated cultures. Numbers describe percent inhibition of HIV-1 replication as compared to control experiments. HIV-1 Drug Wash-Out Experiments PM1 cells were infected with HIV-1 Ba-L (as described above) and cultured for 12 days in the presence of Compound No. 4 at a concentration of 500 nM. Subsequently, the cells were split 1 :1. One of these cultures was further incubated in 500 nM of the test drug for another 12 days. The other culture was washed with Medium and incubated for 12 days in DMSO (control). Culture medium was changed at day 2, 5, 7, 10 and 12 before the drug was removed and at day 2, 5, 7 and 9 after cell splitting. Viability of the cells, cell counts and p24 antigen levels were determined at the indicated days. Results from the experiments are shown in Figure 2. Inhibition of Antiviral Drug-Resistant HIV-1 Isolates PM1 cells were infected with an „omni-drug-resistant HIV-1" (recombinant HIV-1 NL4-3 in which the Protease gene and the 5' part of the Reverse Transcriptase gene was replaced by the corresponding sequences from a omni-drug-resistant clinical isolate, resistant to all currently available anti-HIV drugs. Infected cells were incubated with Compound No. 4 at a concentration of 250, 500 and 1000 nM or DMSO (control). The culture medium was changed every third day. Cell viability (Trypan-blue staining), cell counts and p24 levels were determined at day 6 and 12. At day 12 of infection, the virus replicated vigorously in untreated cultures. Numbers describe percent inhibition of HIV-1 replication as compared to control experiments. in addition, various different „types" of multiple anti-retroviral drug resistant Hiv-1 strains were also tested: "Type" of virus compound No. 4 [%] inhibition of [//Ml virus replication Pi-resistant HIV-1 1.0 95 % 0.5 50 % NNRTi-resistant Hiv-1 1.0 82 % 0.5 71 % NRTi + Pi-resistant HIV-1 1.0 73 % 0.5 68 % Pi: Protease inhibitors NNRTl: Non-Nucleoside Reverse Transcriptase inhibitor NRTI: Nucleoside Reverse Transcriptase inhibitor Long-Time Inhibition of a Clinical HIV-1 Isolate PBMCs from a HIV-1 -infected patient were cultured in various concentrations of Compound No. 4 (125, 250, 500 and 750 nM) or DMSO (control). Culture medium was changed every 3 days during the experiments. Once a week, each culture was split 1 :1 and feeder-PBMCs (feeder cells were prepared and stimulated with PHA-P and PB as outlined in Figure 3) and recombinant IL-2 [10 U / ml] (Roche) were added. Every week, cell viability (Trypan-blue staining), cell counts and p24 levels were determined. Results are shown in Figure 3. Inhibition of cytoplasmic accumulation of incompletely-spliced viral mRNAs caused by compound No. 4 10 8 PM1 cells were infected with HIV-1 Ba-L. Infected cells were washed twice in PBS, split 1 :1 and cultured in either the presence of Compound No. 4 (800 nM) or DMSO (50 ml cultures each). RNAs were isolated at day 7 post-infection. Cytoplasmic (C) RNAs were prepared by lysis of the cells in NP-40 buffer (0.05% NP-40, 5 mM MgCI 2 , 50 mM KCL, 10 mM Hepes-NaOH pH 7.6) as described previously (Greenberg and Ziff 1984 Nature 311 :433-438). Lysates were cleared by centrifugation (Eppendorf table-top centrifuge; 14.000 rpm, 5 min., 4°C) and adjusted to an end concentration of 4 M Guanidine Isothiocyanate. This solution was loaded onto a 5.7 M CsCI cushion. Samples were subsequently spun using a Beckman TLX Ultracentrifuge (TLA 100 rotor) for 2.5 hrs at 100.000 rpm and 24°C. The RNA pellet was resolved in water, treated with phenol/chloro- form/isoamylalcohol (25:24:1 ) and ethanol-precipitated. After centrifugation (Eppendorf table-top centrifuge; 14.000 rpm, 15 min., 4°C), RNA pellets were lyophilised and subsequently dissolved in water for further analysis. Total (T) RNAs were isolated by direct lysis of the cells in 4 M Guanidine Isothiocyanate and purified by centrifugation through a 5.7 M CsCI cushion as outlined above. 25 μg of each, cytoplasmic and total RNA samples, were fractionated by electrophoresis through 1.2% formaldehyde agarose gels, transfered onto Hybond N membranes (Amersham) and subjected to Northern analyses using HIV-1 U3-LTR- (5'-GGTGTGTAGTTCTGCCAATCAGGGAAGTAGCC-3') and U6 snRNA-specific (5'-GATTAGCATGGCCCCTGCGCAAGG-3') radioiabeled synthetic oligonucleotide probes as described previously (Valent et al. 1991 Proc. Natl. Acad. Sci. USA 88:3339-3342). Detection of the exclusively nuclear U6 snRNA served as control for purity of cytoplasmic RNA samples. The HIV-1 -specific probe detects three classes of viral mRNA: unspliced ~ 9kb-class, singly-spliced ~ 4 kb-class and multiply- spliced ~ 2kb-class. Importantly, cytoplasmic accumulation of the ~ 9kb-class and ~ 4 kb-class of viral RNA species is subject to HIV-Rev protein regulation. Intensities of specific bands were evaluated by phospho-imaging. To quantitatively compare the ~ 9kb-class and ~ 4 kb-class of cytoplasmic HIV-1 mRNA, the intensity-values were corrected due to slightly different RNA loads. For this, the intensities of the ~ 2 kb-class of HIV-1 mRNA (which accumulates in the cytoplasm in a HIV-Rev-independent fashion and appears to be unaffected by Compound 4 were equalised and the values for the unspliced and singly-spliced RNA species (~ 9kb-class and ~ 4 kb-class, respectively) were adjusted. ' Results are shown in Figure 4. Inhibition of the Hypusine-formation on elF-5A in living ceils by the compound No. 4 10 7 Jurkat cells were metabolically labeled for 12 hours using 50 μCi [1 ,4-14C] Putrescine Dihydrochloride (108 mCi/mmol; Amersham) in the presence of 0.5 μM or 1.0 μM of compound No. 4 or DMSO (control). Cells were pelleted, washed twice in PBS and lysed in RIPA-buffer (0.1% SDS, 1 % Triton X-100, 1 % Sodium- Deoxycholate, 150 mM NaCI, 0.25 mM PMSF, 1 mM EDTA, 10 mM Tris pH 7.4). Protein concentrations were determined (Bio-Rad protein assay) and equal protein amounts of the various radioiabeled cellular extracts were subjected to elF-5A- specific immunoprecipitation analyses using rabbit polyclonal anti-elF-5A antibody (Schatz et al. 1998 Proc. Natl. Acad. Sci. USA 95: 1607-1612) and analyzed by 14% SDS-PAGE and autoradiography. Results are shown in Figure 5 Effects of compound No. 4 on apoptosis and cell-cycle progression Apoptosis-assay: PBMCs from a healthy donor were cultured for 7 days in the presence of 500 nM of the Compound No. 4 or DMSO (control). Subsequently, cells were washed in PBS and assayed by FACS (FACSCalibur, Becton Dickinson) using a commercially available FITC-coupled annexin V apoptosis-kit according to the manufacturer's protocol (Bender Medsystems # BMS306FI) (cf. Figure 6). Cell cycle-analysis: Jurkat T-cells were cultured for 7 days in the presence of 500 nM of the Compound No. 4 or DMSO (control). Cell cycle analysis was recorded on a FACSCalibur device (Becton Dickinson) using a commercially available propidiumiodide-based DNA staining kit (CycleTest™ Plus; Becton Dickinson) according to the manufacturer's specifications. Results are shown in Figure 6. HBV Experiments Human HepG2-2.2.15 cells (ATCC Cat. No. CRL-11997), chronically infected with HBV, are plated in 96-well microtiter plates in DMEM medium supplemented with fetal bovine serum. After incubation at 37°C in a humidified, 5% CO 2 environment for 16-24 hours, the monolayer of HepG2-2.2.15 cells is washed and the medium is replaced with complete medium containing various concentrations of test compound. Every three days during the experiments, the culture medium is replaced with fresh medium containing the appropriately diluted test compound. Six days following the initial administration of the test compound, the cell culture supernatant is collected and clarified by centrifugation. The cell viability is evaluated by a dye uptake procedure (Promega ' s Cell Titer Aqueous One Solution). Virion-associated HBV DNA present in the tissue culture supernatant is amplified employing PCR technology using primer pairs derived from the HBV strain ayw. Subsequently, the PCR-amplified HBV DNA is detected in real-time by monitoring increases in fluorescence signals that result from exonucleolytic degradation of a quenched fluorescent probe molecule following hybridization of the probe to the amplified HBV DNA (TaqMan; Perkin-Elmer). The same type of experiments was additionally performed with a mutant, Lamivudine-resistant HBV strain, which was transfected into HepG2 cells. Results from HBV experiments: Chronically HBV-infected HepG2 2.2.15 cells were treated with Compound No. 4 Effect of Compound No. 4 on transfected, Lamivudine-resistant, mutant HBV production in HepG2 cells: The minimum inhibitory drug concentration which reduces the viral replication by 50% (IC 5 o) and the minimum drug concentration which inhibits cell growth by 50% (TC 50 ) are calculated by using a regression analysis program for semilόg curve fitting. A therapeutic (selectivity) index (TI) for compound No. 4 is determined by dividing the TC 50 by the IC 50 . Herpes simplex virus type 1 experiments: A virus-induced cytopathic effects (CPE)-inhibition assay procedure using Promega's Cell Titer Aqueous One Solution (MTS, metabolic dye) is employed to evaluate compounds for antiviral activity against herpes simplex virus type 1 (strain HF) in Vero cells (African green monkey cells, ATCC Cat.

Cell controls containing medium alone, virus-infected controls containing medium and virus, drug cytotoxicity controls containing medium and each drug concentration, reagent controls containing culture medium only (no cells), and drug coloπmetπc controls containing drug and medium (no cells) are run simultaneously with the test samples The plates are incubated at 37°C in a humidified atmosphere containing 5% CO 2 until maximum CPE is observed in the untreated virus control cultures (Day 5) CPE inhibition is determined by a dye (MTS) uptake procedure This method measures cell viability and is based on the reduction of the tetrazoiium MTS by mitochondnal enzymes of viable host cells to MTS formazan. MTS (10 μl) is added to each of the plate wells The plates are incubated at 37°C for 4 hours The purple color of the MTS formazan is then measured spectrophotometrically at 490/650 nm The optical density (OD) value of each culture is a function of the amount of formazan produced which is proportional to the number of viable cells A computer program is utilized to calculate the percent of CPE reduction of the virus-infected wells and the % cell viability of uninfected drug control wells Results from Herpes simplex virus type 1 experiments: HSV-infected Vero cells were treated with Compound No. 4 The minimum inhibitory drug concentration which reduces the CPE by 50% (IC 50 ) and the minimum drug concentration which inhibits cell growth by 50% (TC 50 ) are calculated by using a regression analysis program for semilog curve fitting A therapeutic (selectivity) index (TI) for compound No 4 is determined by dividing the TC 50 by the IC 50 Epstein-Barr virus experiments: Human P3HR-1 cells are latently infected with EBV Culturmg these cells in the presence of phorbol ester induces a lytic infection cycle, resulting in stimulation of viral replication within the cells Compound efficacy in this assay is determined using TaqMan PCR technology, and compound toxicity is measured by addition of Promega's Cell Titer Aqueous One Solution (metabolic dye).

Results from Human Herpesvirus 8 experiments: Chronically HHV8-infected BCBL-1 cells were treated with Compound No. 4 The minimum inhibitory drug concentration which reduces the viral replication by 50% (IC 5 o) and the minimum drug concentration which inhibits cell growth by 50% (TC 50 ) are calculated by using a regression analysis program for semilog curve fitting. A therapeutic (selectivity) index (TI) for compound No. 4 is determined by dividing the TC50 by the IC 50 . Varicella-zoster virus experiments: MRC-5 (human embryonic lung fibroblast) cells (ATCC Cat. No. CCL-171 ) are seeded in 24 well plates using Eagle's Minimum Essential Medium (EMEM) supplemented with 10% heat-inactivated fetal bovine serum (FBS), L-glutamine, sodium pyruvate, non-essential amino acids, penicillin, and streptomycin. The plates are then incubated overnight at 37°C and 5% CO 2 . The following day, media is aspirated and approximately 50-100 pfu (plaque forming units) of VZV strain ELLEN is added to the wells of each plate in a volume of 200 μl of assay media (EMEM supplemented with 5% heat-inactivated FBS, L-glutamine, sodium pyruvate, non-essential amino acids, penicillin, and streptomycin). The remaining wells of each plate serve as cellular control wells and receive 200 μl of assay media without virus. The virus is allowed to adsorb onto the cells for 1 hr at 37°C and 5% CO 2 . Two dilutions of each test drug are prepared by diluting them in assay media containing 0.5% Methylcellulose. After the incubation period, 1 ml of each drug dilution is added to triplicate wells of a plate. Assay media (without drug) containing 0.5% Methylcellulose is added to the three cell control wells and to three virus control wells on each plate. The plates are incubated for 9-12 days to allow for plaque formation. The media is then aspirated from the wells and the cells are fixed and stained using 20% Methanol containing Crystal Violet. Plaques are enumerated by microscopic inspection and data is plotted as percent of virus contol. Drug toxicity is determined in parallel by seeding MRC-5 cells in 96 well plates and adding drugs to triplicate wells at two dilutions. After a six day incubation period, cell viability is determined using CellTiter 96 Aqueous One Solution (Promega). Results from Varicella-zoster virus experiments: MRC-5 cells newly infected with VZV were treated with Compound No. 4 The minimum inhibitory drug concentration which reduces the CPE by 50% (IC 50 ) and the minimum drug concentration which inhibits cell growth by 50% (TC 50 ) are calculated by using a regression analysis program for semilog curve fitting. A therapeutic (selectivity) index (TI) for compound No. 4 is determined by dividing the TCso by the IC 50 . Respiratory syncytial virus experiments: A cytoprotection assay procedure using MTS is employed to evaluate compounds for antiviral activity against Respiratory Syncytial Virus (Long) in Vero (African green monkey, ATCC Cat. No. CCL-81 ) cells. The cells are pre-grown overnight at 37°C (2x10 4 /well in 96 well tissue culture plates) with 10% fetal Bovine serum containing Minimum Essential Medium. The positive control for the assay is Interferon-Gamma/Ribavirin. The infection medium contains reduced serum levels (2% FBS). Using half log dilutions with high test starting at 100 μg/ml the drug dilutions are made and added to triplicate cultures in 0.1 ml volume and pre-titrated virus suspension is also added in 0.1 ml volume. Cell control containing medium alone, virus controls containing medium and virus, the drug toxicity controls containing medium and each drug concentrations are run simultaneously with the test samples. The plates are incubated at 37C° with 5% CO 2 until maximum CPE (cytopathogenic effect) observed in untreated virus controls. CPE inhibition is determined by dye uptake procedure (Celltiter- MTS). Celltiter reagent contains a novel tetrazolium (MTS) compound and an electron coupling reagent phenazine ethosulfate (PES). MTS-tetrazolium is bioreduced by cells into a colored formazan product that is soluble in tissue culture medium. This conversion is accomplished by NADPH or NADH produced by dehydrogenase enzymes in metabolically active cells. The amount of soluble formazan produced by cellular reduction of the MTS is measured by the absorbance at 490 nm. The quantity of formazan product as measured by the amount of 490 nm absorbance is directly proportional to the number of living cells in the culture thus allowing the rapid quantitative analysis of the inhibition of virus-induced cell killing by the test substances. Results from Respiratory syncytial virus experiments: Vero cells newly infected with RSV were treated with Compound No. 4 The minimum inhibitory drug concentration which reduces the viral replication by 50% (IC 50 ) and the minimum drug concentration which inhibits cell growth by 50% (TC 50 ) are calculated by using a regression analysis program for semilog curve fitting. A therapeutic (selectivity) index (TI) for compound No. 4 is determined by dividing the TC 50 by the IC 50 . The inhibitory drug concentration which reduces the viral replication by 95% (IC 95 ) and the minimum drug concentration which inhibits cell growth by 95% (TC95) are calculated by using a regression analysis program for semilog curve fitting. A therapeutic (selectivity) index (TI) for compound No. 4 is determined by dividing Bacterial experiments Bacteria We used the E. coli XL-1 blue strain (Stratagene) for the investigation of antibacterial activity.

The media contained the inhibitor at 100 μM, 10 μM, or 1 μM concentrations, respectively. Growth Assay for E. coli The assay was performed as follows: bacteria were seeded to 96-well plates containing the respective inhibitors. The bacteria-containing plates were incubated at 37°C for one day. After incubation time, E. coli growth was assayed by the measurement of the optical density at 610 nm wavelength. Results
