Description: PHOSPHODIESTERASE ISOENZYME DENOMINATED 4 (PDE 4) INHIBITING COMPOUNDS Scope of the Invention This invention covers certain ketones, alcohols, amines, and carboxylic acids represented by the likes of 3-(3-cyclopentyloxy-4-methoxyphenyl)-3- phenylcyanocyclobutan-1-one. These ketones are selective for inhibiting the catalytic site in" the phosphodiesterase isoenzyme denominated 4 (PDE 4 hereafter) while exhibiting little or no affinity for a second binding site on the PDE 4 isoenzyme denominated the high affinity rolipram binding site. A method for treating diseases related to inhibiting the catalytic site in the PDE 4 isoenzyme, e.g., asthma, COPD, etc. is also disclosed. Area of the Invention Cyclic nulceotide phosphodiesterases (PDEs) represent a family of enzymes that hydrolyze the ubiquitous intracellular second messengers, adenosine 3',5'-monophosphate (cAMP) and guanosine 3',5'-monophosphate (cGMP) to their corresponding inactive 5'- monophosphate metabolites. At least five distinct PDE isoenzymes are believed to exist, each possessing unique physical and kinetic charactersitics and each representing a product of a different gene family. Also the distribution of these isoenzymes appears to differ markedly among cell types. Bronchial asthma is a complex, multifactorial disease characterized by reversible narrowing of the airway and hyperreactivity of the respiratory tract to external stimuli. Identification of novel therapeutic agents for asthma is made difficult by the fact that multiple mediators are responsible for the development of the disease. Thus, it seems unlikely that eliminating the effects of a single mediator will have a substantial effect on all three components of chronic asthma. An alternative to the "mediator approach" is to regulate the activity of the cells responsible for the pathophysiology of the disease. One such way is by elevating levels of cAMP (adenosine cyclic 3',5'-monophosphate). Cyclic AMP has been shown to be a second messenger mediating the biologic responses to a wide range of hormones, neurotransmitters and drugs; [Krebs Endocrinology Proceedings of the 4th International Congress Excerpta Medica, 17-29, 1973]. When the appropriate agonist binds to specific cell surface receptors, adenylate cyclase is activated, which converts Mg + 2- ATP to cAMP at an accelerated rate. Cyclic AMP modulates the activity of most, if not all, of the cells that contribute to the pathophysiology of extrinsic (allergic) asthma. As such, an elevation of cAMP would produce beneficial effects including: 1) airway smooth muscle relaxation, 2) inhibition of mast cell mediator release, 3) suppression of neutrophil degranulation, 4) inhibition of basophil degranulation, and 5) inhibition of monocyte and macrophage activation. Hence, 2 compounds that activate adenylate cyclase or inhibit phosphodiesterase should be effective in suppressing the inappropriate activation of airway smooth muscle and a wide variety of inflammatory cells. The principal cellular mechanism for the inactivation of cAMP is hydrolysis of the 3'-phosphodiester bond by one or more of a family of isozymes referred to as cyclic nucleotide phosphodiesterases (PDEs). It has now been shown that a distinct cyclic nucleotide phosphodiesterase (PDE) isozyme, PDE 4, is responsible for cAMP breakdown in airway smooth muscle and inflammatory cells. [Torphy, "Phosphodiesterase Isozymes: Potential Targets for Novel Anti- asthmatic Agents" in New Drugs for Asthma, Barnes, ed. LBC Technical Services Ltd., 1989]. Research indicates that inhibition of this enzyme not only produces airway smooth muscle relaxation, but also suppresses degranulation of mast cells, basophils and neutrophils along with inhibiting the activation of monocytes and neutrophils. Moreover, the beneficial effects of PDE 4 inhibitors are markedly potentiated when adenylate cyclase activity of target cells is elevated by appropriate hormones or autocoids, as would be the case in vivo. Thus PDE 4 inhibitors would be effective in the asthmatic lung, where levels of prostaglandin E2 and prostacyclin (activators of adenylate cyclase) are elevated. Such compounds would offer a unique approach toward the pharmacotherapy of bronchial asthma and possess significant therapeutic advantages over agents currently on the market. The compounds of this invention also inhibit the production of Tumor Necrosis Factor (TNF), a serum glycoprotein. Excessive or unregulated TNF production has been implicated in mediating or exacerbating a number of diseases including rheumatoid arthritis, rheumatoid spondylitis, osteoarthritis, gouty arthritis and other arthritic conditions; sepsis, septic shock, endotoxic shock, gram negative sepsis, toxic shock syndrome, adult respiratory distress syndrome, cerebral malaria, chronic pulmonary inflammatory disease, silicosis, pulmonary sarcoidosis, bone resoφtion diseases, reperfusion injury, graft vs. host reaction, allograft rejections, fever and myalgias due to infection, such as influenza, cachexia secondary to infection or malignancy, cachexia secondary to human acquired immune deficiency syndrome (AIDS), AIDS, ARC (AIDS related complex), keloid formation, scar tissue formation, Crohn's disease, ulcerative colitis, or pyresis, in addition to a number of autoimmune diseases, such as multiple sclerosis, autoimmune diabetes and systemic lupus erythematosis. AIDS results from the infection of T lymphocytes with Human Immunodeficiency Virus (HIV). At least three types or strains of HIV have been identified, i.e., HIV-1, HIV-2 and HIV-3. As a consequence of HIV infection, T-cell-mediated immunity is impaired and infected individuals manifest severe opportunistic infections and/or unusual neoplasms. HIV entry into the T lymphocyte requires T lymphocyte activation. Viruses such as HIV-1 or HIV-2 infect T lymphocytes after T cell activation and such virus protein expression and/or replication is mediated or maintained by such T cell activation. Once an activated T 3 lymphocyte is infected with HIV, the T lymphocyte must continue to be maintained in an activated state to permit HIV gene expression and/or HIV replication. Cytokines, specifically TNF, are implicated in activated T-cell-mediated HIV protein expression and/or virus replication by playing a role in maintaining T lymphocyte activation. Therefore, interference with cytokine activity such as by inhibition of cytokine production, notably TNF, in an HlV-infected individual aids in limiting the maintenance of T cell activation, thereby reducing the progression of HIV infectivity to previously uninfected cells which results in a slowing or elimination of the progression of immune dysfunction caused by HIV infection. Monocytes, macrophages, and related cells, such as kupffer and glial cells, have also been implicated in maintenance of the HIV infection. These cells, like T cells, are targets for viral replication and the level of viral replication is dependent upon the activation state of the cells. [See Rosenberg et al, The Immunopathogenesis of HIV Infection, Advances in Immunology, Vol. 57, 1989]. Monokines, such as TNF, have been shown to activate HIV replication in monocytes and/or macrophages [See Poli et al, Proc. Natl. Acad. Sci., 87:782-784, 1990], therefore, inhibition of monokine production or activity aids in limiting HIV progression as stated above for T cells. TNF has also been implicated in various roles with other viral infections, such as the cytomegalovirus (CMV), influenza virus, adenovirus, and the heφes virus for similar reasons as those noted. TNF is also associated with yeast and fungal infections. Specifically Candida albicans has been shown to induce TNF production in vitro in human monocytes and natural killer cells. [See Riipi et al, Infection and Immunity, 58(9):2750-54, 1990; and Jafari et al, Journal of Infectious Diseases, 164:389-95, 1991. See also Wasan et al, Antimicrobial Agents and Chemotherapy, 35,(10):2046-48, 1991; and Luke et al, Journal of Infectious Diseases, 162:211-214,1990]. The ability to control the adverse effects of TNF is furthered by the use of the compounds which inhibit TNF in mammals who are in need of such use. There remains a need for compounds which are useful in treating TNF-mediated disease states which are exacerbated or caused by the excessive and/or unregulated production of TNF.

This method may be used for the prophylactic treatment or prevention of certain TNF mediated disease states amenable thereto. This invention also relates to a method of treating a human afflicted with a human immunodeficiency virus (HIV), which comprises administering to such human an effective TNF inhibiting amount of a compound of Formula (I) and/or (II). Compounds of Formula (I) and/or (II) are also useful in the treatment of additional viral infections, where such viruses are sensitive to upregulation by TNF or will elicit TNF production in vivo. In addition, compounds of Formula (I) and (LI) are also useful in treating yeast and fungal infections, where such yeast and fungi are sensitive to upregulation by TNF or will elicit TNF production in vivo. Detailed Description of the Invention Phosphodiesterase 4 inhibitors are useful in the treatment of a variety of allergic and inflammatory diseases including: asthma, chronic bronchitis, atopic dermatitis, urticaria, allergic rhinitis, allergic conjunctivitis, vernal conjunctivitis, eosinophilic granuloma, psoriasis, rheumatoid arthritis, septic shock, ulcerative colitis, Crohn's disease, reperfusion injury of the myocardium and brain, chronic glomerulonephritis, endotoxic shock and adult respiratory distress syndrome. In addition, PDE 4 inhibitors are useful in the treatment of diabetes insipidus and central nervous system disorders such as depression and multi-infarct dementia. The viruses contemplated for treatment herein are those that produce TNF as a result of infection, or those which are sensitive to inhibition, such as by decreased replication, directly or indirectly, by the TNF inhibitors of Formula (I) and (II). Such viruses include, but are not limited to HIV-1, HF/-2 and HIV-3, cytomegalovirus (CMV), influenza, adenovirus and the Heφes group of viruses, such as, but not limited to, Herpes zoster and Herpes simplex. This invention more specifically relates to a method of treating a mammal, afflicted with a human immunodeficiency virus (HIV), which comprises administering to such mammal an effective TNF inhibiting amount of a compound of Formula (I) and/or (II). The compounds of this invention may also be used in association with the veterinary treatment of animals, other than in humans, in need of inhibition of TNF production. TNF mediated diseases for treatment, therapeutically or prophylactically, in animals include disease states such as those noted above, but in particular viral infections. Examples of such viruses include, but are not limited to feline immunodeficiency virus (FIV) or other retroviral 9 infection such as equine infectious anemia virus, caprine arthritis virus, visna virus, maedi virus and other lentiviruses. The compounds of this invention are also useful in treating yeast and fungal infections, where such yeast and fungi are sensitive to upregulation by TNF or will elicit TNF production in vivo. A preferred disease state for treatment is fungal meningitis. Additionally, the compounds of Formula (I) and/or (II) may be administered in conjunction with other drugs of choice for systemic yeast and fungal infections. Drugs of choice for fungal infections, include but are not limited to the class of compounds called the polymixins, such as Polymycin B, the class of compounds called the imidazoles, such as clotrimazole, econazole, miconazole, and ketoconazole; the class of compounds called the triazoles, such as fluconazole, and itranazole, and the class of compound called the Amphotericins, in particular Amphotericin B and liposomal Amphotericin B. The compounds of Formula (I) and (II) may also be used for inhibiting and/or reducing the toxicity of an anti-fungal, anti-bacterial or anti-viral agent by administering an effective amount of a compound of Formula (I) and/or (II) to a mammal in need of such treatment. Preferably, a compound of Formula (I) and/or (II) is administered for inhibiting or reducing the toxicity of the Amphotericin class of compounds, in particular Amphotericin B. The term "C1.3 alkyl", "C1.4 alkyl", "Ci.g alkyl" or "alkyl" groups as used herein is meant to include both straight or branched chain radicals of 1 to 10, unless the chain length is limited thereto, including, but not limited to methyl, ethyl, n-propyl, isopropyl, n-butyl, sec- butyl, isobutyl, tert-butyl, and the like. "Alkenyl" means both straight or branched chain radicals of 1 to 6 carbon lengths, unless the chain length is limited thereto, including but not limited to vinyl, 1-propenyl, 2- propenyl, or 3-methyl-2-propenyl. The term "cycloalkyl" or "cycloalkyl alkyl" means groups of 3-7 carbon atoms, such as cyclopropyl, cyclopropylmethyl, cyclopentyl, or cyclohexyl. "Aryl" or "aralkyl", unless specified otherwise, means an aromatic ring or ring system of 6-10 carbon atoms, such as phenyl, benzyl, phenethyl, or naphthyl. Preferably the aryl is monocyclic, i.e, phenyl. The alkyl chain is meant to include both straight or branched chain radicals of 1 to 4 carbon atoms. "Heteroaryl" means an aromatic ring system containing one or more heteroatoms. "Halo" means all halogens, i.e., chloro, fluoro, bromo, or iodo. "Inhibiting the production of LL-1" or "inhibiting the production of TNF" means: a) a decrease of excessive in vivo LL-1 or TNF levels, respectively, in a human to normal levels or below normal levels by inhibition of the in vivo release of LL- 1 by all cells, including but not limited to monocytes or macrophages; b) a down regulation, at the translational or transcriptional level, of excessive in vivo LL-1 or TNF levels, respectively, in a human to normal levels or below normal levels; or 10 c) a down regulation, by inhibition of the direct synthesis of LL-1 or TNF levels as a postranslational event. The phrase "TNF mediated disease or disease states" means any and all disease states in which TNF plays a role, either by production of TNF itself, or by TNF causing another cytokine to be released, such as but not limited to LL-1 or LL-6. A disease state in which LL-1, for instance is a major component, and whose production or action, is exacerbated or secreted in response to TNF, would therefore be considered a disease state mediated by TNF. As TNF-β (also known as lymphotoxin) has close structural homology with TNF-α (also known as cachectin), and since each induces similar biologic responses and binds to the same cellular receptor, both TNF-α and TNF-β are inhibited by the compounds of the present invention and thus are herein referred to collectively as "TNF" unless specifically delineated otherwise. Preferably TNF-α is inhibited. "Cytokine" means any secreted polypeptide that affects the functions of cells, and is a molecule which modulates interactions between cells in immune, inflammatory, or hematopoietic responses. A cytokine includes, but is not limited to, monokines and lymphokines regardless of which cells produce them. The cytokine inhibited by the present invention for use in the treatment of a HFV-infected human must be a cytokine which is implicated in (a) the initiation and/or maintenance of T cell activation and/or activated T cell- mediated HFV gene expression and/or replication, and/or (b) any cytokine-mediated disease associated problem such as cachexia or muscle degeneration. Preferrably, his cytokine is TNF-α. All of the compounds of Formula (I) and (II) are useful in the method of inhibiting the production of TNF, preferably by macrophages, monocytes or macrophages and monocytes, in a mammal, including humans, in need thereof. All of the compounds of Formula (I) and (II) are useful in the method of inhibiting or mediating the enzymatic or catalytic activity of PDE 4 and in treatment of disease states mediated thereby. Preferred compounds are as follows: When Ri for the compounds of Formula (I) and (II) is an alkyl substituted by 1 or more halogens, the halogens are preferably fluorine and chlorine, more preferably a Ci-4 alkyl substituted by 1 or more fluorines. The preferred halo-substituted alkyl chain length is one or two carbons, and most preferred are the moieties -CF3, -CH2F, -CHF2, -CF2CHF2, - CH2CF3, and -CH2CHF2. Preferred Ri substitutents for the compounds of Formula (I) and (II) are CH2-cyclopropyl, CH2-C5-6 cycloalkyl, C4.6 cycloalkyl unsubstituted or substituted with OH, C7.11 polycycloalkyl, (3- or 4-cyclopentenyl), phenyl, tetrahydrofuran-3-yl, benzyl or C 1-2 alkyl unsubstituted or substituted by 1 or more fluorines, -(CH 2 )l-3C(O)O(CH 2 )0-2CH3, -(CH2)l-3θ(CH 2 )0-2CH 3 , and -(CH 2 )2-4θH. When the Ri term is (CR4R5), the R4 and R5 terms are independently hydrogen or alkyl. This allows for branching of the individual methylene units as (CR4R5)n or (CR4R5) m ; each repeating methylene unit is independent of the other, e.g., (CR4R5) n 11 wherein n is 2 can be -CH2CH(-CH3)-, for instance.

By that it is meant 13 that the salt will retain the biological activity of the parent compound and the salt will not have untoward or deleterious effects in its application and use in treating diseases. Pharmaceutically acceptable salts are prepared in a standard manner. If the parent compound is a base it is treated with an excess of an organic or inorganic acid in a suitable solvent. If the parent compound is an acid, it is treated with an inorganic or organic base in a suitable solvent. Pharmaceutical compositions of the present invention comprise a pharmaceutical carrier or diluent and some amount of a compound of the Formula (I) and (II). The compound may be present in an amount to effect a physiological response, or it may be present in a lesser amount such that the user will need to take two or more units of the composition to effect the treatment intended. These compositions may be made up as a solid, liquid or in a gaseous form. Or one of these three forms may be transformed to another at the time of being administered such as when a solid is delivered by aerosol means, or when a liquid is delivered as a spray or . aerosol. The nature of the composition and the pharmaceutical carrier or diluent will, of course, depend upon the intended route of administration, for example parenterally, topically, orally or by inhalation. For topical administration the pharmaceutical composition will be in the form of a cream, ointment, liniment, lotion, pastes, aerosols, and drops suitable for administration to the skin, eye, ear, or nose.

Methods Of Preparation Synthetic Scheme(s) With Textual Description Cyclobutanol 2-Scheme 1 may be prepared from the benzyl nitrile 1 -Scheme 1. which was itself prepared as described in US patent 5,631,286, by first treating with a suitable base, such as an alkyllithium, especially methyllithium, in a suitable solvent, such as ether or tetrahydrofuran, followed by anion quench with epibromohydrin to obtain the epoxymethyl adduct by the method of Corkel and Durst. This intermediate may be isolated or preferably treated in situ with a suitable reagent, such as methylmagnesium iodide, to induce rearrangement to cyclobutanol 2-Scheme 1 Corkel et al., Can. J. Chem;, 56: 505-511, 1978, Decesare, et al., Can. J. Chem.; 59: 1415-1424, 1981, Corkel et al. J. Org. Chem.; 41: 3648-3650, 1976. Oxidation to cyclobutanone 3-Scheme 1 may be achieved by use of a suitable oxidizing reagent, especially a chromium complex, especially pyridinium chlorochromate, in a suitable solvent, such as dichloromethane. Cyclobutanone 3; Scheme 1 may be reduced by one of many possible reducing agents, for example a borohydride, in this example lithium borohydride, in a suitable solvent, such as ethanol, tetrahydrofuran or dimethoxyethane, at temperatures from -78°C to room temperature. The relative ratio of cis to trans isomers of the cyclobutanol 2-Scheme 1 is partially determined by the reducing reagent, solvent and 15 reaction temperature chosen. Separation of the isomers may be achieved by preparation of a derivative, for example, a benzoate derivative, especially the 3-bromobenzoates 4a- and 4b-Scheme 1 by treatment of the isomer mixture with the appropriate benzoyl chloride, and a suitable base, such as triethylamine, in a suitable solvent, such as dichloromethane, followed by silica gel separation. Separated cis and trans cyclobutanols 2a- and 2b-Scheme 1 may be obtained by hydrolysis of each separate isomer of 3-bromobenzoates 4a- or 4b-Scheme 1. for example with sodium hydroxide in an aqueous solvent, such as methanol.

The cyclobutanol isomers la- and lb-Scheme 2 may be separately elaborated to the opposite amine isomers 2a- and 2b-Scheme 2 , by first subjecting them to Mitsunobu reaction conditions, such as diethyl azodicarboxylate, triphenylphosphine and phthalimide, in a suitable solvent, such as tetrahydrofuran, followed by cleavage of the intermediate phthalimide with a suitable reagent, such as hydrazine, in a suitable solvent, such as a mixture of ethanol and tetrahydrofuran.

Cyanocyclobutanone 1 -Scheme 3 may be protected, for example as a ketal, by treatment under suitable reaction conditions, for example with l,2-bis(trimethylsilyloxy)ethane and catalytic trimethylsilyl trifluoromethanesulfonate in a suitable solvent, such as dichloromethane. The nitrile group may then be reduced to the alchol by treatment with suitable reducing reagents, such as di/søbutylaluminum hydride, in a suitable solvent, such as toluene or a mixture ethers, such as tetrahydrofuran and tetrabutyl methyl ether, followed by a borohydride, such as sodium borohydride, in a suitable solvent, such as an alcohol, or an ether, such as dimethoxyethane or tetrahydrofuran at a temperature from -78°C to room temperature, preferably at 0°C. This ketal may then be deprotected by treatment with an acidic reagent, such as hydrogen chloride or p-toluenesulfonic acid, in a suitable solvent, such as aqueous tetrahydrofuran, at elevated temperatures, such as 65°C. The alcohol may then be protected, for example as an acetate, by treatment with suitable reagents, such as acetic anhydride, in the presence of a base, such as pyridine, in a suitable solvent, such as dichloromethane, at room temperature to refluxing temperatures, preferably 35°C, to provide cyclobutanone 2-Scheme 3- Cyclobutanone 2-Scheme 3 may be homologated to the carboxylic ester 4-Scheme 3. for example by formation of a ketene thioacetal 3-Scheme 3. by treatment with 2-lithio-2-trimethylsilyl- 1,3-dithiane, prepared with an alkyllithium, especially n-butyllithium, in a suitable solvent, such as tetrahydrofuran, at -78°C to room temperature, preferably at 0°C. [Carey et al, J. Org. Chem., 37: 1926, 1972]. Ketene thioacetal 3-Scheme 3 may be hydrolyzed by suitable reagents, such as trifluoroacetic acid, in a suitable solvent, such as acetonitrile and water, at elevated temperature, such as 60°C, then hydrogen peroxide, then esterification by one of various methods, such as with an alcohol, such as methanol, and an acidic reagent, such as trimethylsilyl chloride or hydrogen chloride, or with diazomethane in ether. The preferred hydrolysis method is treatment with a mercury salt, such as mercury(II) chloride, and an acid, such as perchloric acid, in an alcoholic solvent, such as methanol, at elevated temperature, preferably at reflux. Alcohol mixture 4-Scheme 3 may be oxidized to the the aldehydes 5a- and 5b-Scheme 3 by various methods, for example with a chromium reagent, such as pyridinium chlorochromate, in a 17 suitable solvent, such as dichloromethane. Separation of the cis and trans isomers can conveniently be carried out at this point. Aldehyde 5a- or 5b-Scheme 3 may be condensed with an amine- delivering reagent, such as hydroxylamine hydrochloride, [Saidna et al, Synth, 190, 1982] in the presence of a base, such as pyridine, in a suitable solvent, such as toluene at refluxing temperature, preferably with removal of water from the reaction. The resulting hydroxylimine 6a- or 6b-Scheme 3 may be dehydrated to the nitrile with a variety of reagents, [Carotti, Synth, 56, 1979] such as trifluoromethanesulfonic anhydride, in the presence of a base, such as triethylamine, in a suitable solvent, such as dichloromethane. Ester 7a- or 7b-Scheme 3 may be saponified to the cyclobutanecarboxylic acid 8a- or 8b-Scheme 3 by a number of methods, such as treatment with potassium hydroxide in a mixture of tetrahydrofuran, methanol and water. 18 Scheme 3 a,b,c, \ o §3, cis isomer 6a, cis isomer. 5b_, trans isomer 6b, trans isomer 7a, cis isomer 8a, cis isomer 7b, trans isomer 8b, trans isomer Reagents: a) TMSOCH 2 CH 2 OTMS, TMSOTf, CH 2 CI 2 , -78°C to RT; b) DIBAL-H, THF, TBME, -15°C; c) NaBH 4 , DME, 0°C; d) HCl, H 2 0, THF, 60°C; e) Ac 2 0, pyridine, CH 2 CI 2 , 35°C; f) 2-TMS-1 ,3-dithiane, rvBuLi/hexanes, THF, 0°C; g) HCI0 4 , HgCI 2 , MeOH, 65°C; h) PCC, CH 2 CI 2 ; i) NH 2 OH HCl, pyridine, toluene, 4 A sieves, 110°C; j) Tf 2 0, Et g N, CH 2 CI 2 ; k) i.
