Description: ANT -VIRAL TRIAZA COMPOUNDS The invention relates to the use of a family of new- synthetic triamine compounds which can be used in pharmaceutical compositions such as antivirals. BACKGROUND OF THE INVENTION The number of biologically active compounds useful as antivirals is very limited. Particularly limited are anti-HIV agents. Currently approved anti-HIV drugs include nucleoside analogs such as AZT. Unfortunately, recent results of a European trial of AZT in asymptomatic HIV-infected persons showed that administration of the drug caused no difference in survival after three years. In the face of slow progress on the development of an effective AIDS vaccine, a National Task Force on AIDS Drug Development has been established to explore new approaches to AIDS chemotherapy. It is unlikely that a cure for AIDS will be discovered because HIV integrates itself into the host's genome and the main strategy to combat the disease is to keep the HIV virus from proliferating. At least 16 steps in the HIV life cycle have been identified as possible points for therapeutic intervention, yet all of the anti- HIV drugs licensed in the U.S. so far (AZT, ddl and ddC) are nucleoside inhibitors of HIV reverse transcriptase (RT) . Rapid mutation of the virus presents a key challenge to antiretroviral drug therapy and AZT- resistant strains of HIV appear in patients after prolonged treatment. Non-nucleoside RT inhibitors are currently under investigation, but it is expected that combinations of drugs operating by different mechanisms will combat viral resistance most successfully. Hence, there is an urgent search for new drugs acting at different stages in the HIV life cycle. More recently discovered anti-HIV agents include certain bicyclams and quinolines such as quinoline-4-amine. The mechanism of action of the quinoline compound is unknown, but the bicyclams are reported to be inhibitors of HIV uncoating. Another type of compound, the triaza macrocycles, have been used primarily for metal complexation. Previously, no biological activity has been suggested for these compounds. SUMMARY OF THE INVENTION The present invention provides a family of triaza compounds which show antiviral properties for use against a number of viruses including HIV-1 and HIV-2. The basic structure of the compounds is represented by formula I: formula I wherein W represents a bridge carbon which is additionally bonded to at least one polar or non-polar side group substituent selected from the group consisting of double- bonded carbon, double bonded oxygen, hydroxyl, alkyl of about one to 10 carbons, alkoxy of about one to 10 carbons, aryl of about 7 to 10 carbons, a halogen, methyl halogen, methylene halide, epoxide (or oxirane) , acyl, CH 2 0H and hydrogen; halogen is F, Cl, I or Br; halide is F 2 , Cl 2 , I- or Br 2 . X and Y independently represent an aromatic group, an alkyl group, a sulfonyl group or a carbonyl group said aromatic group selected from the group consisting of Ar, Ar sulfonyl, Ar carboxy and Ar alkyl where Ar is an aromatic cyclic or heterocyclic ring having from five to seven members. The alkyl group which may be present for X and Y or as a substituent on Ar has from one to ten carbons. X and Y are not both an alkyl group. Preferably at least one of X or Y is an aromatic group. Z represents a group listed for X and Y or a fused aryl moiety; said aryl moiety having from seven to ten carbons. Z may also represent hydrogen. a and d independently represent a number from zero to 10; b and c independently represent a number from one to 10; and e represents a number from zero to three; and preferably, a + d + e _> 1. Formula I represents a cyclic or acyclic structure and contains sufficient hydrogens for a stable molecule. Moieties for C a and C d can include double bonds particularly when the structure for formula I is acyclic. In one preferred embodiment, W is ethene, X and Y are tosyl, Z is benzyl or - COR 2 , a, d, and e are one, and b and c are three. The compounds of formula I have antiinfective activity and have a range of uses including as a pharmaceutical agent for use in the prevention and chemoprophylaxis of viral illnesses. The compounds can also be used as an antiinfective or antiseptic as a coating or additive on articles such as medical devices, contraceptives, dressings, and in blood product preparations and similar biologicals. A method of inhibiting a virus comprises contacting the virus, a virus-containing milieu, a virus-infectable cell or a virus-infected cell with a virus-inhibiting amount of the compound of formula I .

The compounds of this invention possess valuable pharmacological properties for both human and veterinary medicine. The compounds display antiviral and antitu or effects and are useful particularly in the prevention and chemoprophylaxis of viral illnesses. The compounds can also be used in vitro and employed in admixture with carriers, germicides, fungicides, or soaps, etc., for use as antiseptics solutions and the like, particularly in conjunction with hospital housekeeping procedures to combat viruses such as herpes and HIV. They are also useful as intermediates in the production of other polyamine drugs by the method of U.S. Patent No. 5,021,409 and in the synthesis of metal chelating compounds, e.g., by methods of Bradshaw et al . , Aza-Crown Macrocycles. Wiley, New York, 1993. The pharmacologically active compounds of this invention can be processed in accordance with conventional methods of pharmacy to produce medicinal agents for administration to patients, e.g., mammals including humans. The pharmacological compounds of the invention are generally administered to animals, including but not limited to mammals and avians; more preferably to mammals including humans, primates and avians including poultry. The compounds of this invention can be employed in admixture with conventional pharmaceutically acceptable diluents, excipients, carriers and other components such as vitamins to form pharmaceutical compositions. Pharmaceutical compositions may be prepared by known principles for parenteral, enteral and topical application. Preferably, the administration is parenteral . Generally, the compounds of this invention are dispensed in unit dosage form comprising 10 to 1000 mg in a pharmaceutically acceptable carrier per unit dosage. The dosage of the compounds according to this invention generally is about 0.1 to 100 mg/kg body weight/day preferably 0.1 to 20 mg/kg/day when administered to patients, e.g., humans to treat viral infections such as HIV. Viruses share certain common characteristics; they consist of a nucleic acid genome which may be double- stranded DNA, single stranded DNA, single-strand positive RNA, single-strand negative RNA and double-stranded RNA. The nucleic acid is surrounded by protective protein shell (capsid) and the protein shell may be enclosed in an envelope which further includes a membrane. The treatment of viral disease has been approached by inhibiting absorption or penetration of virus into cells, inhibiting intracellular processes which lead to the synthesis of viral components, or inhibition of release of newly synthesized virus from the infected cell. The inhibition of one or more of these steps depends on the chemistry or mode of action of the virus. The compounds of the invention have been shown to have antiviral effect against various viruses including retroviruses, particularly HIV which researchers believe to be a positive strand RNA virus. Effectiveness has also been shown against other viruses which infect humans including cytomegalovirus and herpesvirus which are believed to be double strand DNA viruses, influenza virus which is believed to be a negative strand RNA virus, and also rous sarcoma virus which infects avians. The invention will be illustrated by the following non- limiting examples. I. .

Alkene 22(59%) was prepared by Richman-Atkins cyclization of 18 with 3-chloro-2-chloromethyl-l-propene. g. Another series of analogues was prepared from alkene 22. By methods described previously for functional- ization of compound 2 (Scheme 1) , hydroboration/oxidation of 22 gave alcohol 23, which was then converted to chloride 24 in greater than 90% yield overall. The chloromethyl group of 25 survives the harsh conditions required for tosyl cleavage, yielding 25. Transannular cyclization was attempted by treating this compound with potassium carbonate in isopropanol, but a 59% yield of azetidine 26 was obtained along with a minor amount of elimination product (27) . All of the analogues appearing in Schemes 1-3 can be synthesized in multiple-gram quantities by these methods. Most can be purified by recrystallization. Certain amines in these series occur as viscous oils or glasses, but in many cases crystalline HCl salts can be obtained. The HCl salts of 1 and 2 have also been prepared, with the expectation that enhanced water solubility improves the ease of administration of these drugs. IV. Synthesis of Compounds 41, 42, 43, 44, 45 and 46 Other symmetrical analogues 41 9-Benzyl-3-keto-l, 5-ditosyl-l, 5, 9-triazacyclododecane 42 9-Benzyl-3-methyl-l, 5-ditosyl-l, 5,9- triazacyclododecane 43 9-Benzyl-3-methylene-1, 5-ditosyl-l, 5,9- triazacyclododecane-9-oxide 44 9-Acyl-3-methylene-1, 5-ditosyl-l, 5,9- triazacyclododecane 45 9-Alkyl-3-methylene-l, 5-ditosyl-l, 5, 9- triazacyclododecane 46 9-Acyl-3-methylene-1, 5-ditosyl-l, 5, 9- triazacyclododecane epoxide in the family of triaza compounds to be used in the invention are shown in Scheme 4. SCKEWE 4 Compounds 41 to 46 are closely related to CADA. They are designed to have enhanced water solubility and to be capable of modification of biomolecules by electrostatic or hydrophobic interaction at the double bond position for reversible binding of proteins, such as HIV capsid proteins, integrase or proviral DNA by S N 2 ' attack of an 0, N or S at W. Compounds 41, 42 and 43 are prepared in one step by oxidation or reduction of 1. Ketone 41 is prepared by ozonolysis of 1-HCl in methanol, followed by reductive workup with dimethyl sulfide. The exocyclic double bond is reduced to give 42 by catalytic hydrogenation under conditions known for hydrogenation of disubstituted alkenes in the presence of benzylamine functionality. Compound 41 has improved water solubility and 42 has similar polarity to 1, but neither can undergo the S N 2 ' covalent binding mechanism mentioned above. Ketone 41 is capable of Schiff-base condensation with an amino group (e.g. of a lysine side-chain) . Amine N-oxide 43 is prepared by reaction of 1 with hydrogen peroxide in methanol. The water solubility of this compound should be similar to that of 1»HC1 so it can be used to test whether the protonation equilibrium (1 -» 1*H + ) is important to the mechanism of action. Compound 12, previously prepared according to Scheme 2, is an important analogue of 1 and an intermediate in the synthesis of 44 - 46. Acylation to 44 (R = H, alkyl or aryl) replaces the benzyl group with acyl groups of various sizes to test the steric and electronic requirements for this site. If protonation of the nitrogen atom is important, then alkylation of 12 to 45 (R = methyl, ethyl, β-hydroxyethyl, isopropyl, etc.) independently tests the effects of steric bulk and polarity at this site. A series of analogues of type 45 can be prepared in which R is a benzyl group bearing a polar substituent (OH, N0 2 , S0 3 H, C0 2 H, NH 2 or NMe 2 ) to solubilize the drug. Finally, epoxidation of 44 with m- CPBA or Oxone will give 46 with enhanced polarity and reactivity at the exocyclic site toward nucleophilic attack. Synthesis of compound 43 was as follows: 43 9-Benzyl-3-methylene-1,5-ditosyl-l,5,9-triaza-9-N- oxide-cyclododecane (ARB 95-212) (Compound 43) . H 2 0 2 Method. In a 250 mL round-bottomed flask, 3.00 g (5.2 mmol) of CADA was diluted with 100 mL of ethanol and 30 g of 30% H 2 0 2 . A magnetic stir bar was added, condenser attached and the mixture was heated by means of an oil bath to reflux. After 5 h, the clear solution was allowed to cool and then concentrated by rotary evaporation. The residue was diluted with 50 mL of CHC1 3 and 30 mL of water and stirred briefly to dissolve the contents. The organic layer was separated, washed with water (2 x 25 mL) then with 25 mL of saturated aq. NaCl and dried (MgS0 4 ) . Filtration of the drying agent and concentration of the filtrate afforded a bubbly film. Further purification was performed by gravity column chromatography with neutral alumina. (Act. 1, 60 - 325 mesh) using CHC1 3 followed by 20:1 (v/v) chloroform:ethanol to elute Compound 43. Concentration of the fractions to a bubbly film followed by trituration with acetone afforded 1.44 g (47%) of Compound 43 as a white solid, mp 129-130°C. Oxone Method. A mixture of 2.50 g (4.29 mmol) of CADA, 1.25 g (14.8 mmol) of sodium hydrogen carbonate, 2.71 g (4.4 mmol) of Oxone, 25 mL of water and 75 mL of ethanol was stirred with a magnetic stir bar and heated (oil bath) to 45-50°C for 24 h. After cooling to room temperature, the solid was removed by suction filtration and washed with 40 mL of ethanol (CADA was recovered by washing the solid with CHC1 3 and concentration of the chloroform filtrate) . The combined ethanol filtrates were concentrated and a CHC1 3 solution of the residue was dried over MgS0 4 . Removal of the drying agent by filtration and concentration of the filtrate afforded 1.20 g (46%) of Compound 43 ( X H NMR) as a bubbly film. Purification by gravity column chromatography with neutral alumina as described in the previous method afforded 0.35 g of Compound 43 as a white solid after trituration with acetone. A sample submitted for elemental analysis was dried at 40°C (0.2 mm) for 4 h.

IX Synthesis of Compound 211 An analogue of compound 44 is compound 213 9- (Ethyloxycarbonyl) -3-methylene-1,5-ditosyl-l,5, 9- triazacyclododecane. Compound 213 was prepared as follows: 9- (Ethyloxycarbonyl) -3-methylene-1,5-ditosyl-l,5,9- triazacyclododecane (compound 213) . In an oven dried 250 mL round-bottoned flask, 8.20 g (14.1 mmol) of CADA was diluted with 65 mL of freshly distilled (P 2 O s )l,2- dichloroethane. A magnetic stir bar, reflux condenser with a gas inlet and oil bath were added then the system purged with nitrogen. Ethyl chloroformate (1.70 mL; 17.8 mmol) was added by syringe and the solution heated at reflux for 5 h. The solvent was removed using a rotary evaporator with a 40 C C water bath. Dilution of the oily residue with 60 mL of a solution of 2:3 (v/v) ethyl acetate:hexane caused a white precipitate to form at room temperature after scratching the glass. The solid was filtered and washed with 3 x 30 mL of a solution of 2:3 (v/v) ethyl acetate:hexane giving 6.63 g (83%) of Compound 213, mp 125 - 126°C (after drying at 78°C and 0.9 mm for 19 h) .

Synthesis of Compounds 50, 51, 52 and 53 Another series of compounds is illustrated by formula II. These compounds include 50 9-Benzyl-l-formyl-3-methylene-1, 5, 9- triazacyclododecane 51 9-Benzyl-l-formyl-3-methylene-5-tosyl-1, 5,9- triazacyclododecane 52 9-Benzyl-3-methylene-l-tosyl-l, 5, 9- triazacyclododecane 53 e.g. 9-Benzyl-3-methylene-l-acyl-5-tosyl-1, 5, 9- triazacyclododecane formula II 29 These compounds have three different substituents (X, Y and Z) on the three nitrogen atoms of a 12-membered ring. The synthetic plan utilizes a series of reactions reported for selective, unsymmetrical substitution of 1,5, 9-triazacyclododecane. The intermediate is 3- methylene-1, 5, 9-triazacyclododecane (27), which can be obtained quantitatively by elimination of HCl from 25 Scheme 3. Reaction of 27 with neat DMF dimethyl acetal gives 47 in high yield as shown in Scheme 5. Monoalkylation with benzyl bromide will give 48 or 49 (or both) . Both of these salts are synthetically useful, but the completion of the synthesis is illustrated with 48. SCHEME 5 53 52 51 50 Alkaline hydrolysis will yield formamide 50, which is an unsymmetrical example of formula 29, where X = H, Y = CHO and Z = benzyl. Tosylation of 50 and alkaline hydrolysis will give 51 and 52 respectively. Compound 52 is a mono- detosylated analogue of 1 and the missing tosyl group can be replaced with almost any alkyl, acyl, alkanesulfonyl or arenesulfonyl group of interest (53, Y = various ) . For example, Y = benzyl shows the effect of two protonation sites, while Y = p-bromobenzensulfonate shows the effect of enhancing the sulfonamide leaving group ability. Candidates for improved water solubility include compounds of type 29 in which Z = benzyl and X and Y are benzenesulfonyl groups bearing polar subs ituents, such as NH 2 , OH or C0 2 H. VI. Synthesis of macrocyclic triamines of varying ring size: compounds 55 and 60 Varied ring size and incorporation of amide functionality into the lare ring in macrocylic lactams are shown in Scheme 6. SCHEME 6 55 56 Almost any linear triamine of type 54 (m, n = 2 - 6, R » alkyl, aryl or acyl) is available by methods used for the synthesis of linear and macrocyclic polyamines. Cyclization of these triamines with methyl acrylate or chloroacetyl chloride gives the corresponding macrocycles (55; a = 2 or 1, respectively) . The acrylate cyclization is precedented by formation of the phenyl-substituted analogue of 55 (a = 2, m » 1, n = 1, R = H) by reaction of the triamine with methyl cinnamate. Chloroacetyl chloride has been used in the syntheses of numerous polyazamacrocycles by the so-called crablike cyclization, which is usually carried out in refluxing acetonitrile without resort to high-dilution conditions. The low reactivity of the amide nitrogen atom of 55 enables selective functionalization of the third nitrogen, affording 56 (Y = alkyl, acyl, alkanesulfonyl or arenesulfonyl) . Both series of macrocyclic lactams (55 and 56) can then be reduced to macrocyclic triamines under various conditions for the reduction of amides to amines. The resulting compounds are saturated analogues of type 29 bearing three different X, Y and Z groups, any of which could bear water-solubilizing substituents, and having ring sizes in the range of 9 - 18 carbon and nitrogen atoms. VII. Synthesis of open-chain or non-macrocyclic analogues 58, 59, 60, 61, 61, 63 and 64 Open-chain and non-macrocyclic analogues are shown in Scheme 7. SCHEME 7 These analogues are synthesized from a series of l,n-alkanediamines via the N-tosylphthalimide derivatives (57, n = 2 - 7) . Alkylation of the sodium, potassium or cesium salt of 57 with either 2-chloromethyl-3-chloro-l- propene or 2-iodomethyl-3-iodo-l-propene will give chain- extended intermediate 58 or 59. It is possible to control the product selectivity of the reaction by varying stoichiometry and order of addition of the reactants. Intermediates of type 58 bear a second leaving group (X) , which will be displaced by various amine or sulfonamide nucleophiles, yielding 60 (Y = R',S0 2 R' or S0 2 Ar) . Cleavage of the phthalimide protecting group by hydrazine will give primary amine 61, which can be acylated or sulfonated to analogue series 62. The same Gabriel synthesis approach can be applied to 59 (n = 2-8) ; an unsymmetrical series of compounds, differing only chain length relative to 59, can be prepared by reaction of 58 with 57. The resulting series of compounds includes symmetrical and unsymmetrical open- chain analogues of 1 containing the allylic tosylamide functionality and a total of 3 - 4 nitrogen atoms. VIII. Synthesis of bicyclic compounds 66, 67 and 68 An additional series of analogues consists of the bicyclic compounds 34-36 shown below: Examples of these bicyclic compounds and their syntheses are shown in Scheme 8. SCHEME B 66 68 In bridged pyridine compound 66, corresponding to 34, the tertiary amino basic site is replaced by a pyridine nitrogen atom and the aromatic benzyl group is replaced by the aromatic pyridine ring. The Richman- Atkins synthetic approach shown has been used successfully in the preparation of many bridged pyridine host compounds. By analogy with known cyclizations of 65 (n = 1) , reaction with 2-chloromethyl-3-chloropropene or 2-iodomethyl-3-iodopropene under high-dilution conditions gives analogue 66 (n = 1) . The entire series in which n = 1 - 6 is preparable by this method. In 35 and 36 the second ring is fused to two carbon atoms of CADA, leaving the center nitrogen atom free for substituent Z. Two benzene fused examples of 35 and 36 are 67 and 68, which are shown in Scheme 8 with their syntheses. The five steps shown in each case parallel the 5-step synthesis of CADA (Scheme 1) and yields should be comparable. The fused benzene ring mimics the benzyl group of CADA, leaving substituent Z variable. In all three cases (66- 68) the fused aromatic ring can bear polar substituents enhancing water solubility. Other analogs such as those functionalized with polar groups for increased solubility can be synthesized using the synthesis methods described above, coupled with various steps known in the art and described, e.g., by T.J. Richman et al . , Macrocyclic Polyamines : 1,4,7,10,13,16 - Hexaazacyclooctadecane in Organic Synthesis. Coll. Vol. VI. Noland, .E., Ed., Wiley, New York, 1988, pp. 652-662; Bradshaw et al . Aza-Crown Macrocycles. Wiley, New York, 1993, chp . IV. Such polar groups include, for example, NO, N0 2 , NH 2 , OH, SH, OR, SR, COR, S0 2 R, SOR, halide (F, Cl, Br, I) , NHR, NR 2 , HCO, COOH, COOR, C≡N, alkyl halide, etc. (R = alkyl of 1-10 carbons) . Antiviral activity was tested as follows: EXAMPLE 1 In these tests, the IC 50 (50% inhibitory concentration) is the concentration resulting in 50% cellular toxicity. EC 50 (median effective concentration) is the compound concentration that reduces infection by 50%. The effectiveness of a compound against a virus is expressed as TI 50 (median therapeutic index) which is determined by the ratio IC S0 /EC 50 . Compounds of the invention were tested to assess the efficacy of the inhibitory effect of the compounds against HIV. The screen was carried out in a soluble formazan assay by the tetrazolium method according to Weislow et al . , J. Natl. Cancer Inst . 81:577-586, 1989. The compound was dissolved in dimethyl sulfoxide (DMSO) (final cone, less than .25%) and then diluted 1:100 in cell culture medium. Because DMSO is toxic to cells at concentration above 1%, the concentration of the compound in DMSO should be at least lOuM before dilution with aqueous solution. Various concentrations of the compound were tested against HIV-1 in CEM-IW cells. After six days incubation at 37°C in a 5% carbon dioxide atmosphere, viable cells were analyzed through addition of tetrazolium salt XTT followed by incubation to allow formazan color development. Cell viability was viewed microscopically and detected spectrophotometrically to quantitate formazan production. In a test against HIV-1 (6S) -AZT sensitive, the compound CADA (compound 1) was found active. The IC 50 index was greater than 5.00 x 10 "5 M; the EC 50 was 1.20 x 10" 6 M; and the TI 50 (IC/EC) was greater than 2.6 x 10 +1 . In a second test, the compound from another batch of CADA was confirmed active in a primary screen. The IC S0 index was greater than 6.00 X 10' 6 M; the EC 50 was 2.40 x 10 "6 M; and the TI 50 was greater than 2.50 X 10°. EXAMPLE 2 Testing was carried out as described in Example 1 against additional HIV strains. The compound CADA was active against the following viruses using the indicated cell lines: IIIB strain of HIV-l/MT-4 cell line HIV-2/CEM cell line SIV/MT-4 cell line AZT - resistant HIV-l/MT-2 and MT-4 cell lines AZT - sensitive HIV-l/MT-4 cell line A17, a strain of HIV-1 resistant to most of the non- nucleoside reverse transcriptase inhibitors/MT-2 and MT-4 cell lines, WeJo, a clinical isolate of HIV-1/PBMCs (fresh human peripheral blood mononuclear cells) . The compound was found to be active against these viruses with an EC 50 of 2uM, a IC 50 greater than 30μm and a TI 50 greater than 15. This means that good activity and low cell toxicity were observed in the micromolar range of concentration of the compound. EXAMPLE 3 Studies were carried out to determine the mechanism of action of the compounds in the HIV life cycle. At least 16 steps in the HIV life cycle have been identified as possible points for therapeutic intervention, yet all the anti-HIV drugs licensed in the U.S. so far (AZT, ddl and ddC) are nucleoside inhibitors of HIV reverse transcriptase (RT) . Another group of antivirals, the bicyclams, are believed to act at an early stage in the retrovirus replicative cycle, apparently inhibiting viral uncoating. The action of other anti-HIVs such as the quinolines is unknown. The studies were based on activity of the compound against HIV-1 in peripheral blood lymphocytes. The results with different solutions and different batches of the compound confirm that the compound is active at submicromolar levels (EC 50 ) and has low cytotoxicity (IC 50 ) . The results of the studies on the mechanism of reaction are summarized in the Table below: RT activity (rA.dT) ID 50 (μM) No Inhibition Time of Action Time Course LTR/gag No Inhibition of proviral DNA synthesis Protease Activity (rp HPLC) ID 50 (μM) 40 Mo-MO/HIV-1 Ba-L Infection EC 50 (μM) 1.5 (fresh) IC 50 (μM) over 30 (high test) Latent Infection (Ul/TNF) No inhibition Preliminary mechanism of action studies showed that the compound CADA does not appear to inhibit HIV reverse transcriptase or HIV protease at the concentrations determined to be effective in the in vitro assays. It is believed that the CADA acts prior to the integration of virus into the cellular genome, but it does not appear to inhibit virus attachment or cell fusion. It was concluded that the mechanism of action of the new compounds is different than those of either of the two classes of AIDS drugs currently in use or in clinical trials (reverse transcriptase and protease inhibitors) . EXAMPLE 4 Additional studies on stability, solubility, formulation and pharmokinetics were carried out. Plasma elimination and urinary recovery from mice following i.v. administeration were examined. Solubility of the compound in human, mouse, rat plasma and plasma ultrafiltrate were examined. Stability of the compound in human urine was determined. The conclusions of these studies are as follows: 1. The compound is stable in mouse and rat plasma (t ι/2 greater than 200 hrs) and is stable in pH 4.0 buffer (t 12 139 hrs) and in human plasma (t 12 126 hrs) . 2. The compound is soluble in human plasma at 37°C (1-2 ug/mL = 2-3uM) . 3. The compound can be formulated for animal studies at a concentration of 1.2uM in a 1:20 mixture of DMSO and normal saline (pH 2.7) . 4. The compound is detectable in mouse plasma up to 2 hours after in vivo intravenous administration. EXAMPLE 5 Additional antiviral testing was carried out to assess the efficacy of the compounds of the invention against human cytomegalovirus (HCMV) , herpes simplex virus (HSV) , rous sarcoma virus (RSC) and influenza virus (FLU WSN) . Compounds tested were the HCl salts of the products compounds (1) , (2) and (12) and non-salt compound (1) . The results are summarized in the table below TABLE 2 PDR = poor dose response The data in the table represents the concentration of compound causing 50% protection against virus. While not wishing to be bound by any one theory, one hypothesis is that in the mechanism of action of the invention, the drug inhibits retroviral uncoating by binding to a hydrophobic pocket on one of the HIV capsid proteins. A series of hydrophobic compounds, such as disoxaril or Win 51711 are known to inhibit picornavirus replication by this mechanism and various other drugs seem to neutralize rhinoviruses by binding to a specific hydrophobic pocket within the virion capsid protein. The major HIV capsid protein (p24) is a potential target, although it has not been shown that such compounds can be as effective against an enveloped virus as they are against simple icosahedral viruses. Anti-influenza A drugs amantadine and rhimantidine inhibit virus replication by blocking a proton channel associated with capsid protein M2, thereby interfering with virus uncoating. The bicyclams are the only reported inhibitors of HIV uncoating. CADA superficially resembles bicyclam as a macrocyclic polyamine. CADA' s basic tertiary amino group should be protonated at physiologic pH and both compounds could function as metal chelating agents. These similarities with bicyclams are only superficial, however, because the toluenesulfonamide groups of 1 should render it a very weak metal chelator and 1 is much more lipophilic (hydrophobic) than bicyclams which should be polyprotonated a physiologic pH. Although a sulfonamide, CADA is cationic rather than anionic and does not belong to the polyanionic sulfate class of anti- HIV agents that inhibit binding of the virion to target cells . Inhibition of the HIV enzyme integrase is a second hypothetical mechanism of action consistent with the observation that CADA acts at an early stage of HIV replication. Integrase controls the incorporation of virally transcribed DNA into the host genome, a key step in HIV replication. Many drugs have been found to bind and inhibit HIV-1 integrase in enzymatic in vitro experiments, but none of these compounds prevents HIV replication in intact cells. It is possible that CADA is the first therapeutically active drug operating by integrase inhibition. Whether CADA is an uncoating inhibitor, an integrase inhibitor or operates by another mechanism, its discovery leads to a new class of drugs complementing inhibitors of reverse transcriptase and protease, used individually or in combination therapy. CADA has a unique activity profile and it operates at an early stage of HIV replication by a mechanism not involving adhesion, fusion or reverse transcriptase inhibition. The discovery shows the potential for a new approach to AIDS chemotherapy. It is likely that the synthesis of hundreds of analogues will produce potent anti-HIV agents with improved solubility and bioavailability. EXAMPLE 6 Additional antiviral testing was carried out to test the efficacy of compounds of the invention against human cytomegalovirus (HCMV) and another herpesvirus, Variecella Zoster Virus (VZV) . The compounds tested were compound (1) , the HCl salt of compound (1) , Compounds 211, 43, 213 and 214. The results are summarized in the table below. TABLE 3 Antiviral Screening Results for Herpesviruses Screening system: human foreskin fibroblast cells. EC 50 values are concentrations (μM)required to inhibit viral cytopathogenicity by 50%.

Note: None of the compounds tested showed significant activity against Herpes Simplex virus (HSV type 1 or 2) or Epstein Barr virus (EBV) , except for Compound 213, which showed anti-EBV activity (EC 50 6.7 μM; CC 50 > 180 μM; SI > 26.9) . 2 Values not in parentheses are results of a semi- automated CPE-inhibition assay for human cytomegalovirus (HCMV) .

These results show antiviral activity in the submicromolar range. EXAMPLE 8 The efficacy of intravenously administered CADAΗC1 in rabbits during ocular Varicella Zaster Virus (VZV) infection was determined. Intravenous therapy with 5 mg/kg/day CADA-HCl for 11 days was compared with 20mg/kg/day acyclovir (ACV) intravenous therapy. Rabbits were bilaterally inoculated with an intrastromal injection of 100 μL of McKrae strain VZV titer of 10 5 /ml. On day 2 to 3 post inoculation (PI) animals were evaluated and divided into equal groups. Intravenous therapy of CADAΗCl, acyclovir and placebo saline was initiated immediately after animal grouping and continued through day 11 PI . Two groups received CADA-HCl intravenous therapy for 9 days, one group at a "low-dose" of 5 mg/kg/day and another group at a "high-dose" of 10 mg/kg/day. Other groups received similar IV therapy with ACV at 20 mg/kg/day and with placebo. As a result, VZV-induced corneal stromal and iris disease demonstrated a positive response to therapy with CADA-HCl and with ACV. CADAΗCl at both concentrations was effective in reducing the development of stromal disease. By day 6 PI, acyclovir was intermediate between placebo and low dose CADAΗCl. Both CADA-HCl and ACV also showed a positive therapeutic response in reducing iris disease development. In efficacy against iris disease (uveitis) CADA-HCl and ACV both showed a positive effect. By day 5 PI, CADA-HCl was more effective than acyclovir therapy in reducing development of iritis and in speeding resolution of VZV disease.
