Description: 1,2-DIAZEPANE DERIVATIVES AS INTERLEUKIN-IBETA CONVERTING ENZYME INHIBITORS TECHNICAL FIELD OF THE INVENTION The present invention relates to novel classes of compounds which are caspase inhibitors, in particular interleu in-lβ converting enzyme ("ICE") inhibitors. This invention also relates to pharmaceutical compositions comprising these compounds. The compounds and pharmaceutical compositions of this invention are particularly well suited for inhibiting caspase activity and consequently, may be advantageously used as agents against interleukin-1- ("IL-1") , apoptosis-, interferon-γ inducing factor- (IGIF) , or interferon-γ- ("IFN-γ") mediated diseases, including inflammatory diseases, autoimmune diseases, destructive bone disorders, proliferative disorders, infectious diseases, and degenerative diseases. This invention also relates to methods for inhibiting caspase activity and decreasing IGIF production and IFN-γ production and methods for treating interleukin-1, apoptosis-, and interferon-γ- mediated diseases using the compounds and compositions of this invention. This invention also relates to methods of preparing the compounds of this invention. BACKGROUND OF THE INVENTION Interleukin 1 ("IL-1") is a major pro- inflammatory and immunoregulatory protein that stimulates fibroblast differentiation and proliferation, the production of prostaglandins, collagenase and phospholipase by synovial cells and chondrocytes, basophil and eosinophil degranulation and neutrophil activation. Oppenheim, J.H. et al, Immunology Today, 7, pp. 45-56 (1986) . As such, it is involved in the pathogenesis of chronic and acute inflammatory and autoimmune diseases. For example, in rheumatoid arthritis, IL-1 is both a mediator of inflammatory symptoms and of the destruction of the cartilage proteoglycan in afflicted joints. Wood, D.D. et al . , Arthritis Rheum. 26, 975, (1983); Pettipher, E.J. et al . , Proc. Natl. Acad. Sci. USA 71, 295 (1986); Arend, W.P. and Dayer, J.M., Arthritis Rheum. 38, 151 (1995). IL-1 is also a highly potent bone resorption agent. Jandiski, J.J., J. Oral Path 17, 145 (1988); Dewhirst, F.E. et al . , J. Immunol. 8, 2562 1985). It is alternately referred to as "osteoclast activating factor" in destructive bone diseases such as osteoarthritis and multiple myeloma. Bataille, R. et al . , Int. J. Clin. Lab. Res. 21(4), 283 (1992) . In certain proliferative disorders, such as acute myelogenous leukemia and multiple myeloma, IL-1 can promote tumor cell growth and adhesion. Bani, M.R., J. Natl . Cancer Inst . 83, 123 (1991); Vidal-Vanaclocha, F., Cancer Res. 54, 2667 (1994) . In these disorders, IL-1 also stimulates production of other cytokines such as IL- 6, which can modulate tumor development (Tartour et al., Cancer Res. 54, p. 6243 (1994) . IL-1 is predominantly produced by peripheral blood monocytes as part of the inflammatory response and exists in two distinct agonist forms, IL-lα and IL-lβ. Mosely, B.S. et al . , Proc . Nat . Acad. Sci. , 84, pp. 4572-4576 (1987); Lonnemann, G. et al., Eur. J. Immunol., 19, pp. 1531-1536 (1989). IL-lβ is synthesized as a biologically inactive precursor, pIL-lβ. pIL-lβ lacks a conventional leader sequence and is not processed by a signal peptidase. March, C.J., Nature , 315, pp. 641-647 (1985). Instead, pIL-lβ is cleaved by interleukin-lβ converting enzyme ("ICE") between Asp-116 and Ala-117 to produce the biologically active C-terminal fragment found in human serum and synovial fluid. Sleath, P.R., et al . , J. Biol. Chem. , 265, pp. 14526-14528 (1992); A.D. Howard et al . , J. Immunol., 147, pp. 2964-2969 (1991) . ICE is a cysteine protease localized primarily in monocytes. It converts precursor IL-lβ to the mature form. Black, R.A. et al., FEBS Lett. , 247, pp. 386-390 (1989); Kostura, M.J. et al., Proc. Natl. Acad. Sci. U.S.A., 86, pp. 5227- 5231 (1989) . Processing by ICE is also necessary for the transport of mature IL-lβ through the cell membrane. ICE is a member of a family of homologous enzymes called caspases. These homologs have sequence similarities in the active site regions of the enzymes. Such homologs (caspases) include TX (or ICE re ι_u or ICH- 2) (Faucheu, et al . , EMBO J . , 14, p. 1914 (1995); Kamens J., et al., J. Biol. Chem. , 270, p. 15250 (1995); Nicholson et al . , J. Biol. Chem. , 270 15870 (1995)), TY (or ICE re __i ) (Nicholson et al . , J. Biol . Chem. , 270, p. 15870 (1995); ICH-1 (or Nedd-2) (Wang, L. et al . , Cell, 78, p. 739 (1994)), MCH-2, (Fernandes-Alnemri, T. et al., Cancer Res . , 55, p. 2737 (1995), CPP32 (or YAMA or apopain) (Fernandes-Alnemri, T. et al . , J. Biol. Chem. , 269, p. 30761 (1994); Nicholson, D.W. et al . , Nature , 376, p. 37 (1995)), and CMH-1 (or MCH-3) (Lippke, et al., J. Biol. Chem. , (1996); Fernandes-Alnemri, T. et al . , Cancer Res . , (1995)). Each of these ICE homologs, as well as ICE itself, is capable of inducing apoptosis when overexpressed in transfected cell lines. Inhibition of one or more of these homologs with the peptidyl ICE inhibitor Tyr-Val-Ala-Asp-chloromethylketone results in inhibition of apoptosis in primary cells or cell lines. Lazebnik et al . , Nature, 371, p. 346 (1994). Caspases also appear to be involved in the regulation of programmed cell death or apoptosis. Yuan, J. et al., Cell, 75, pp. 641-652 (1993); Miura, M. et al., Cell, 75, pp. 653-660 (1993); Nett-Fiordalisi, M.A. et al., J. Cell Biochem. , 17B, p. 117 (1993). In particular, ICE or ICE homologs are thought to be associated with the regulation of apoptosis in neurodegenerative diseases, such as Alzheimer's and Parkinson's disease. Marx, J. and M. Baringa, Science, 259, pp. 760-762 (1993); Gagliardini, V. et al . , Science, 263, pp. 826-828 (1994). Therapeutic applications for inhibition of apoptosis may include treatment of Alzheimer's disease, Parkinson's disease, stroke, myocardial infarction, spinal atrophy, and aging. ICE has been demonstrated to mediate apoptosis (programmed cell death) in certain tissue types. Steller, H., Science, 267, p. 1445 (1995); Whyte, M. and Evan, G., Nature, 376, p. 17 (1995); Martin, S.J. and Green, D.R., Cell, 82, p. 349 (1995); Alnemri, E.S., et al., J. Biol. Chem., 270, p. 4312 (1995); Yuan, J. Curr . Opin. Cell Biol. , 7, p. 211 (1995) . A transgenic mouse with a disruption of the ICE gene is deficient in Fas- mediated apoptosis (Kuida, K. et al . , Science 267, 2000 (1995) ) . This activity of ICE is distinct from its role as the processing enzyme for pro-IL-lβ. It is conceivable that in certain tissue types, inhibition of ICE may not affect secretion of mature IL-lβ, but may inhibit apoptosis. Enzymatically active ICE has been previously described as a heterodimer composed of two subunits, p20 and plO (20kDa and lOkDa molecular weight, respectively) . These subunits are derived from a 45kDa proenzyme (p45) by way of a p30 form, through an activation mechanism that is autocatalytic. Thornberry, N.A. et al . , Nature, 356, pp. 768-774 (1992) . The ICE proenzyme has been divided into several functional domains: a prodomain (pl4) , a p22/20 subunit, a polypeptide linker and a plO subunit. Thornberry et al . , supra ; Casano et al . , Genomics, 20, pp. 474-481 (1994) . Full length p45 has been characterized by its cDNA and amino acid sequences. PCT patent applications WO 91/15577 and WO 94/00154. The p20 and plO cDNA and amino acid sequences are also known. Thornberry et al . , supra . Murine and rat ICE have also been sequenced and cloned. They have high amino acid and nucleic acid sequence homology to human ICE. Miller, D.K. et al . , Ann. N.Y. Acad. Sci., 696, pp. 133-148 (1993) ; Molineaux, S.M. et al . , Proc. Nat. Acad. Sci., 90, pp. 1809-1813 (1993) . The three-dimensional structure of ICE has been determined at atomic resolution by X-ray crystallography. Wilson, K.P., et al . , Nature , 370, pp. 270-275 (1994). The active enzyme exists as a tetramer of two p20 and two plO subunits. Recently, ICE and other members of the ICE/CED- 3 family have been linked to the conversion of pro- IGIF to IGIF or to the production of IFN-γ in vivo (PCT application PCT/US96/20843 , filed 12/20/96, published 6/26/97 under publication no. WO 97/22619, which is incorporated herein by reference) . IGIF is synthesized in vivo as the precursor protein "pro-IGIF". Interferon-gamma inducing factor (IGIF) is an approximately 18-kDa polypeptide that stimulates T-cell production of interferon-gamma (IFN-γ). IGIF is produced by activated Kupffer cells and macrophages in vivo and is exported out of such cells upon endotoxin stimulation. Thus, a compound that decreases IGIF production would be useful as an inhibitor of such T-cell stimulation which in turn would reduce the levels of IFN-γ production by those cells. - 6 - IFN-γ is a cytokine with immunomodulatory effects on a variety of immune cells. In particular, IFN-γ is involved in macrophage activation and Thl cell selection (F. Belardelli, APMIS, 103, p. 161 (1995)). IFN-γ exerts its effects in part by modulating the expression of genes through the STAT and IRF pathways (C. Schindler and J.E. Darnell, Ann. Rev. Biochem. , 64, p. 621 (1995) ; T. Taniguchi, J. Cancer Res. Clin. Oncol., 121, p. 516 (1995) ) . Mice lacking IFN-γ or its receptor have multiple defects in immune cell function and are resistant to endotoxic shock (S. Huang et al . , Science, 259, p. 1742 (1993); D. Dalton et al . , Science, 259, p. 1739 (1993); B.D. Car et al . , J . Exp . Med . , 179, p. 1437 (1994)). Along with IL-12, IGIF appears to be a potent inducer of IFN-γ production by T cells (H. Okamura et al . , Infection and Immunity, 63, p. 3966 (1995); H. Okamura et al . , Nature, 378, p. 88 (1995); S. Ushio et al . , J. Immunol. , 156, p. 4274 (1996) ) . IFN-γ has been shown to contribute to the pathology associated with a variety of inflammatory, infectious and autoimmune disorders and diseases. Thus, compounds capable of decreasing IFN-γ production would be useful to ameliorate the effects of IFN-γ related pathologies. Accordingly, compositions and methods capable of regulating the conversion of pro-IGIF to IGIF would be useful for decreasing IGIF and IFN-γ production in vivo, and thus for ameliorating the detrimental effects of these proteins which contribute to human disorders and diseases. Caspase inhibitors represent a class of compounds useful for the control of inflammation or apoptosis or both. Peptide and peptidyl inhibitors of ICE have been described. PCT patent applications WO 91/15577; WO 93/05071; WO 93/09135; WO 93/14777 and WO 93/16710; and European patent application 0 547 699. Such peptidyl inhibitors of ICE have been observed to block the production of mature IL-lβ in a mouse model of inflammation (vide infra) and to suppress growth of leukemia cells in vitro (Estrov et al . , Blood 84, 380a (1994)) . However, due to their peptidic nature, such inhibitors are typically characterized by undesirable pharmacologic properties, such as poor cellular penetration and cellular activity, poor oral absorption, poor stability and rapid metabolism. Plattner, J.J. and D.W. Norbeck, in Drug Discovery Technologies, CR. Clark and W.H. Moos, Eds. (Ellis Horwood, Chichester, England, 1990), pp. 92-126. This has hampered their development into effective drugs. Non-peptidyl compounds have also been reported to inhibit ICE in vitro. PCT patent application WO 95/26958; US Patent 5,552,400; Dolle et al . , J. Med. Chem. , 39, pp. 2438-2440 (1996) . It is not clear however whether these compounds have the appropriate pharmacological profiles to be therapeutically useful. Accordingly, the need exists for compounds that can effectively inhibit caspases for use as agents for preventing and treating chronic and acute forms of IL-1- mediated diseases, apoptosis-, IGIF-, or IFN-γ-mediated diseases, as well as inflammatory, autoimmune, destructive bone, proliferative, infectious, or degenerative diseases. SUMMARY OF THE INVENTION The present invention provides novel classes of compounds, and pharmaceutically acceptable derivatives thereof, that are useful as caspases inhibitors, in particular as ICE inhibitors. These compounds can be used alone or in combination with other therapeutic or - 8 - prophylactic agents, such as antibiotics, immunomodulators or other an i-inflammatory agents, for the treatment or prophylaxis of diseases mediated by IL- 1, apoptosis, IGIF or IFN-γ. According to a preferred embodiment, the compounds of this invention are capable of binding to the active site of ICE and inhibiting the activity of that enzyme.

In chemical formulas, parenthesis are used herein to denote connectivity in molecules or groups. In particular, parentheses are used to indicate: 1) that more than one atom or group is bonded to a particular atom; or 2) a branching point (i.e., the atom immediately before the open parenthesis is bonded both to the atom or group in the parentheses and the atom or group immediately after the closed parenthesis) . An example of the first use is " -N (alkyl) 2 " . indicating two alkyl groups bond to an N atom. An example of the second use is "-C(0)NH 2 ", indicating a carbonyl group and an amino ("NH 2 ") group both bonded to the indicated carbon atom. A "-C(0)NH 2 " group may be represented in other ways, including the following structure: O NH 2 - 13 - Substituents may be represented in various forms. These various forms are known to the skilled practitioner and may be used interchangeably. For example, a methyl substituent on a phenyl ring may be represented in any of the following forms : ■c "-. H .. rf c^rCBj x ^γ Me , σ Various forms of substituents such as methyl are used herein interchangeably. Other definitions are set forth in the specification where necessary.

Each stereogenic carbon may be of the R or S configuration. Although specific compounds and scaffolds exemplified in this application may be depicted in a particular stereochemical configuration, compounds and scaffolds having either the opposite stereochemistry at any given chiral center or mixtures thereof are also envisioned. All such isomeric forms of these compounds are expressly included in the present invention, as well as pharmaceutically acceptable derivative thereof. The term "pharmaceutically acceptable derivative" means any pharmaceutically acceptable salt, ester, or salt of such ester, of a compound of this invention or any other compound which, upon administration to a recipient, is capable of providing (directly or indirectly) a compound of this invention or an anti-ICE active metabolite or residue thereof. Pharmaceutically acceptable salts of the compounds of this invention include, for example, those derived from pharmaceutically acceptable inorganic and organic acids and bases. Examples of suitable acids include hydrochloric, hydrobromic, sulfuric, nitric, perchloric, fumaric, maleic, phosphoric, glycolic, lactic, salicylic, succinic, toluene-p-sulfonic, tartaric, acetic, citric, methanesulfonic, formic, - 35 - benzoic, malonic, naphthalene-2-sulfonic and benzenesulfonic acids. Other acids, such as oxalic, while not in themselves pharmaceutically acceptable, may be employed in the preparation of salts useful as intermediates in obtaining the compounds of the invention and their pharmaceutically acceptable acid addition salts. Salts derived from appropriate bases include alkali metal (e.g., sodium), alkaline earth metal (e.g., magnesium), ammonium and N- (Cι_ 4 al yl)4 + salts. This invention also envisions the "quaternization" of any basic nitrogen-containing groups of the compounds disclosed herein.

It should be understood that the compounds of this invention may be modified by appropriate functionalities to enhance selective biological properties. Such modifications are known in the art and include those which increase biological penetration into a given biological system (e.g., blood, lymphatic system, central nervous system) , increase oral availability, increase solubility to allow administration by injection, alter metabolism and alter rate of excretion. In addition, the compounds may be altered to pro-drug form such that the desired compound is created in the body of the patient as the result of the action of metabolic or other biochemical processes on the pro-drug. Such pro- - 39 - drug forms typically demonstrate little or no activity in in vitro assays. Some examples of pro-drug forms include ketal, acetal, oxime, imine and hydrazone forms of compounds which contain ketone or aldehyde groups, especially where they occur in the Y group of the compounds of this invention. Other examples of pro-drug forms include the hemi-ketal, hemi-acetal, acyloxy ketal, acyloxy acetal, ketal, acetal and enol forms that are described herein. Compositions and Methods The compounds of this invention are caspase inhibitors, particularly ICE inhibitors. Accordingly, these compounds are capable of targeting and inhibiting events in IL-1-, apoptosis-, IGIF-, and IFN-γ-mediated diseases, and, thus, the ultimate activity of that protein in inflammatory diseases, autoimmune diseases, destructive bone, proliferative disorders, infectious diseases, and degenerative diseases. For example, the compounds of this invention inhibit the conversion of precursor IL-lβ to mature IL-lβ by inhibiting ICE. Because ICE is essential for the production of mature IL- 1, inhibition of that enzyme effectively blocks initiation of IL-1-mediated physiological effects and symptoms, such as inflammation, by inhibiting the production of mature IL-1. Thus, by inhibiting IL-lβ precursor activity, the compounds of this invention effectively function as IL-1 inhibitors. Compounds of this invention also inhibit conversion of pro-IGIF into active, mature IGIF by inhibiting ICE. Because ICE is essential for the production of mature IGIF, inhibition of ICE effectively blocks initiation of IGIF-mediated physiological effects and symptoms, by inhibiting production of mature IGIF. IGIF is in turn essential for the production of IFN-γ. ICE - 40 - therefore effectively blocks initiation of IFN-γ- mediated physiological effects and symptoms, by inhibiting production of mature IGIF and thus production of IFN-γ. The pharmaceutical compositions and methods of this invention, therefore, will be useful for controlling caspase activity in vivo . The compositions and methods of this invention will thus be useful for controlling IL- 1, IGIF or IFN-γ levels in vivo and for treating or reducing the advancement, severity or effects of IL-1-, apoptosis-, IGIF-, or IFN-γ-mediated conditions, including diseases, disorders or effects. Pharmaceutical compositions of this invention comprise a compound of formulae (I) or (II) or a pharmaceutically acceptable salt thereof and a pharmaceutically acceptable carrier. Such compositions may optionally comprise an additional therapeutic agent. Such agents include, but are not limited to, an anti- inflammatory agent, a matrix metalloprotease inhibitor, a lipoxygenase inhibitor, a cytokine antagonist, an immunosuppressant , an anti-cancer agent, an anti-viral agent, a cytokine, a growth factor, an immunomodulator, a prostaglandin or an anti-vascular hyperproliferation compound. The term "pharmaceutically acceptable carrier" refers to a non-toxic carrier that may be administered to a patient, together with a compound of this invention, and which does not destroy the pharmacological activity thereof . Pharmaceutically acceptable carriers that may be used in the pharmaceutical compositions of this invention include, but are not limited to, ion exchangers, alumina, aluminum stearate, lecithin, serum proteins, such as human serum albumin, buffer substances such as phosphates, glycine, sorbic acid, potassium sorbate, partial glyceride mixtures of saturated - 41 - vegetable fatty acids, water, salts or electrolytes, such as protamine sulfate, disodium hydrogen phosphate, potassium hydrogen phosphate, sodium chloride, zinc salts, colloidal silica, magnesium trisilicate, polyvinyl pyrrolidone, cellulose-based substances, polyethylene glycol, sodium carboxymethylcellulose, polyacrylates, waxes, polyethylene-polyoxypropylene-block polymers, wool fat and self-emulsifying drug delivery systems (SEDDS) such as α-tocopherol, polyethyleneglycol 1000 succinate, or other similar polymeric delivery matrices. In pharmaceutical composition comprising only a compound of formulae (I) or (II) as the active component, methods for administering these compositions may additionally comprise the step of administering to the subject an additional agent. Such agents include, but are not limited to, an anti-inflammatory agent, a matrix metalloprotease inhibitor, a lipoxygenase inhibitor, a cytokine antagonist, an immunosuppressant, an anti-cancer agent, an anti-viral agent, a cytokine, a growth factor, an immunomodulator, a prostaglandin or an anti-vascular hyperproliferation compound. The term "pharmaceutically effective amount" refers to an amount effective in treating or ameliorating an IL-1-, apoptosis-, IGIF- or IFN-γ-mediated disease in a patient. The term "prophylactically effective amount" refers to an amount effective in preventing or substantially lessening IL-1-, apoptosis-, IGIF- or IFN- γ-mediated diseases in a patient. The compounds of this invention may be employed in a conventional manner for controlling IGIF and IFN-γ levels in vivo and for treating diseases or reducing the advancement or severity of effects which are mediated by IL-1, apoptosis, IGIF or IFN-γ. Such methods of treatment, their dosage levels and requirements may be - 42 - selected by those of ordinary skill in the art from available methods and techniques. For example, a compound of this invention may be combined with a pharmaceutically acceptable adjuvant for administration to a patient suffering from an IL-1-, apoptosis-, IGIF- or IFN-γ-mediated disease in a pharmaceutically acceptable manner and in an amount effective to lessen the severity of that disease. Alternatively, the compounds of this invention may be used in compositions and methods for treating or protecting individuals against IL-1, apoptosis-, IGIF, or IFN-γ mediated diseases over extended periods of time. The compounds may be employed in such compositions either alone or together with other compounds of this invention in a manner consistent with the conventional utilization of enzyme inhibitors in pharmaceutical compositions. For example, a compound of this invention may be combined with pharmaceutically acceptable adjuvants conventionally employed in vaccines and administered in prophylactically effective amounts to protect individuals over an extended period of time against IL-1-, apoptosis-, IGIF, or IFN-γ mediated diseases. The compounds of formulae (I) or (II) may also be co-administered with other caspase or ICE inhibitors to increase the effect of therapy or prophylaxis against various IL-1-, apoptosis-, IGIF- or IFN-γ mediated diseases . In addition, the compounds of this invention may be used in combination either conventional anti- inflammatory agents or with matrix metalloprotease inhibitors, lipoxygenase inhibitors and antagonists of cytokines other than IL-lβ. The compounds of this invention can also be administered in combination with immunomodulators (e.g., bropirimine, anti-human alpha-interferon antibody, IL-2, - 43 - GM-CSF, methionine enkephalin, interferon-alpha, diethyldithiocarbamate, tumor necrosis factor, naltrexone and EPO) , with prostaglandins, or with antiviral agents (e.g., 3TC, polysulfated polysaccharides, ganiclovir, ribavirin, acyclovir, alpha interferon, trimethotrexate and fancyclovir) or prodrugs of these or related compounds to prevent or combat IL-1-mediated disease symptoms such as inflammation. When the compounds of this invention are administered in combination therapies with other agents, they may be administered sequentially or concurrently to the patient. Alternatively, pharmaceutical or prophylactic compositions according to this invention comprise a combination of a compound of formula (I) or (II) and another therapeutic or prophylactic agent. The pharmaceutical compositions of this invention may be administered orally, parenterally, by inhalation spray, topically, rectally, nasally, buccally, vaginally or via an implanted reservoir. We prefer oral administration. The pharmaceutical compositions of this invention may contain any conventional non-toxic pharmaceutically-acceptable carriers, adjuvants or vehicles. In some cases, the pH of the formulation may be adjusted with pharmaceutically acceptable acids, bases or buffers to enhance the stability of the formulated compound or its delivery form. The term parenteral as used herein includes subcutaneous, intracutaneous, intravenous, intramuscular, intra-articular, intrasynovial, intrasternal, intrathecal, intralesional and intracranial injection or infusion techniques. The pharmaceutical compositions may be in the form of a sterile injectable preparation, for example, as a sterile injectable aqueous or oleaginous suspension. This suspension may be formulated according to techniques known in the art using suitable dispersing or wetting - 44 - agents (such as, for example, Tween 80) and suspending agents. The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-toxic parenterally-acceptable diluent or solvent, for example, as a solution in 1, 3-butanediol . Among the acceptable vehicles and solvents that may be employed are mannitol, water, Ringer's solution and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose, any bland fixed oil may be employed including synthetic mono- or diglycerides . Fatty acids, such as oleic acid and its glyceride derivatives are useful in the preparation of injectables, as are natural pharmaceutically-acceptable oils, such as olive oil or castor oil, especially in their polyoxyethylated versions. These oil solutions or suspensions may also contain a long-chain alcohol diluent or dispersant, such as those described in Pharmacopeia Helvetica, or a similar alcohol. The pharmaceutical compositions of this invention may be orally administered in any orally acceptable dosage form including, but not limited to, capsules, tablets, and aqueous suspensions and solutions.

These compositions can be prepared by mixing a compound of this invention with a suitable non-irritating excipient which is solid at room temperature but liquid at the rectal temperature and therefore will melt in the rectum to release the active components. Such materials include, but are not limited to, cocoa butter, beeswax and polyethylene glycols. Topical administration of the pharmaceutical compositions of this invention is especially useful when the desired treatment involves areas or organs readily accessible by topical application. For application topically to the skin, the pharmaceutical composition should be formulated with a suitable ointment containing the active components suspended or dissolved in a carrier. Carriers for topical administration of the compounds of this invention include, but are not limited to, mineral oil, liquid petroleum, white petroleum, propylene glycol, polyoxyethylene polyoxypropylene compound, emulsifying wax and water.

A typical preparation will contain from about 5% to about 95% active compound (w/w) . Preferably, such preparations contain from about 20% to about 80% active compound. When the compositions of this invention comprise a combination of a compound of formulae (I) or (II) and one or more additional therapeutic or prophylactic agents, both the compound and the additional agent should be present at dosage levels of between about 10% to 80% of the dosage normally administered in a monotherapy regime . Upon improvement of a patient's condition, a maintenance dose of a compound, composition or combination of this invention may be administered, if necessary. Subsequently, the dosage or frequency of administration, or both, may be reduced, as a function of the symptoms, to a level at which the improved condition is retained when the symptoms have been alleviated to the - 48 - desired level, treatment should cease. Patients may, however, require intermittent treatment on a long-term basis upon any recurrence or disease symptoms. As the skilled artisan will appreciate, lower or higher doses than those recited above may be required. Specific dosage and treatment regimens for any particular patient will depend upon a variety of factors, including the activity of the specific compound employed, the age, body weight, general health status, sex, diet, time of administration, rate of excretion, drug combination, the severity and course of the disease, and the patient's disposition to the disease and the judgment of the treating physician.

Enzyme assay with UV-visible substrate This assay is run using an Succinyl-Tyr-Val- Ala-Asp-p-Nitroanilide substrate. Synthesis of analogous substrates is described by L.A. Reiter (Int. J. Peptide Protein Res. , 43, pp. 87-96 (1994)). The assay mixture contains : 65 μl buffer (lOmM Tris, 1 mM DTT, 0.1% CHAPS @pH 8.1) 10 μl ICE (50 nM final concentration to give a rate of ~lmOD/min) 5 μl DMSO/Inhibitor mixture 20 μl 400μM Substrate (80 μM final concentration) lOOμl total reaction volume The visible ICE assay is run in a 96-well microtiter plate. Buffer, ICE and DMSO (if inhibitor is present) are added to the wells in the order listed. The components are left to incubate at room temperature for 15 minutes starting at the time that all components are present in all wells. The microtiter plate reader is set to incubate at 37 °C. After the 15 minute incubation, substrate is added directly to the wells and the reaction is monitored by following the release of the chromophore - 60 - (pNA) at 405 - 603 nm at 37 °C for 20 minutes. A linear fit of the data is performed and the rate is calculated in mOD/min. DMSO is only present during experiments involving inhibitors, buffer is used to make up the volume to 100 μl in the other experiments. 2. Enzyme Assay with Fluorescent Substrate This assay is run essentially according to Thornberry et al . , Nature, 356 pp. 768-774 (1992), using substrate ___!_ referenced in that article. The substrate is: Acetyl-Tyr-Val-Ala-Asp-amino-4-methylcoumarin (AMC). The following components are mixed: 65 μl buffer (lOmM Tris, ImM DTT, 0.1% CHAPS @pH8.1) 10 μl ICE (2 - 10 nM final concentration) 5 μl DMSO/inhibitor solution 20 μl 150 μM Substrate (30 μM final) lOOμl total reaction volume The assay is run in a 96-well microtiter plate. Buffer and ICE are added to the wells. The components are left to incubate at 37 °C for 15 minutes in a temperature-controlled wellplate. After the 15 minute incubation, the reaction is started by adding substrate directly to the wells and the reaction is monitored at 37 °C for 30 minutes by following the release of the AMC fluorophore using an excitation wavelength for 380 nm and an emission wavelength of 460 nm. A linear fit of the data for each well is performed and a rate is determined in fluorescence units per second. For determination of enzyme inhibition constants (Kj_) or the mode of inhibition (competitive, uncompetitive or noncompetitive) , the rate data determined in the enzyme assays at varying inhibitor concentrations are computer-fit to standard enzyme - 61 - kinetic equations (see I.H. Segel, Enzyme Kinetics, Wiley- Interscience, 1975) . The determination of second order rate constants for irreversible inhibitors was performed by fitting the fluorescence vs time data to the progress equations of Morrison. Morrison, J.F., Mol. Cell. Biophys . , 2, pp. 347-368 (1985). Thornberry et al . published a description of these methods for measurement of rate constants of irreversible inhibitors of ICE. Thornberry, N.A. , et al . Biochemistry, 33, pp. 3923-3940 (1994) . For compounds where no prior complex formation can be observed kinetically, the second order rate constants (ki nac t) are derived directly from the slope of the linear plots of k 0 ]-, s vs. inhibitor concentration [I] . For compounds where prior complex formation to the enzyme can be detected, the hyperbolic plots of ko^g vs. [I] are fit to the equation for saturation kinetics to first generate K-j_ and k'. The second order rate constant •^inact i- s then given by k'/Kj_. PBMC Cell assay IL-lβ Assay with a Mixed Population of Human Peripheral Blood Mononuclear Cells (PBMC) or Enriched Adherent Mononuclear Cells Processing of pre-IL-lβ by ICE can be measured in cell culture using a variety of cell sources. Human PBMC obtained from healthy donors provides a mixed population of lymphocyte subtypes and mononuclear cells that produce a spectrum of interleukins and cytokines in response to many classes of physiological stimulators. Adherent mononuclear cells from PBMC provides an enriched source of normal monocytes for selective studies of cytokine production by activated cells. - 62 - Experimental Procedure : An initial dilution series of test compound in DMSO or ethanol is prepared, with a subsequent dilution into RPMI-10% FBS media (containing 2 mM L-glutamine, 10 mM HEPES, 50 U and 50 ug/ml pen/strep) respectively to yield drugs at 4x the final test concentration containing 0.4% DMSO or 0.4% ethanol. The final concentration of DMSO is 0.1% for all drug dilutions. A concentration titration which brackets the apparent Kj_ for a test compound determined in an ICE inhibition assay is generally used for the primary compound screen. Generally 5-6 compound dilutions are tested and the cellular component of the assay is performed in duplicate, with duplicate ELISA determinations on each cell culture supernatant. PBMC Isolation and IL-1 Assay: Buffy coat cells isolated from one pint human blood (yielding 40-45 ml final volume plasma plus cells) are diluted with media to 80 ml and LeukoPREP separation tubes (Becton Dickinson) are each overlaid with 10 ml of cell suspension. After 15 min centrifugation at 1500- 1800 xg, the plasma/media layer is aspirated and then the mononuclear cell layer is collected with a Pasteur pipette and transferred to a 15 ml conical centrifuge tube (Corning) . Media is added to bring the volume to 15 ml, gently mix the cells by inversion and centrifuge at 300 xg for 15 min. The PBMC pellet is resuspended in a small volume of media, the cells are counted and adjusted to 6 x 10 6 cells/ml. For the cellular assay, 1.0 ml of the cell suspension is added to each well of a 24 -well flat bottom tissue culture plate (Corning), 0.5 ml test compound dilution and 0.5 ml LPS solution (Sigma #L-3012; 20 ng/ml solution prepared in complete RPMI media; final LPS - 63 - concentration 5 ng/ml). The 0.5 ml additions of test compound and LPS are usually sufficient to mix the contents of the wells. Three control mixtures are run per experiment, with either LPS alone, solvent vehicle control, and/or additional media to adjust the final culture volume to 2.0 ml. The cell cultures are incubated for 16-18 hr at 37 °C in the presence of 5% C0 2 . At the end of the incubation period, cells are harvested and transferred to 15 ml conical centrifuge tubes. After centrifugation for 10 min at 200 xg, supernatants are harvested and transferred to 1.5 ml Eppendorf tubes. It may be noted that the cell pellet may be utilized for a biochemical evaluation of pre-IL-lβ and/or mature IL-lβ content in cytosol extracts by Western blotting or ELISA with pre-IL-lβ specific antisera. Isolation of Adherent Mononuclear cells: PBMC are isolated and prepared as described above. Media (1.0 ml) is first added to wells followed by 0.5 ml of the PBMC suspension. After a one hour incubation, plates are gently shaken and nonadherent cells aspirated from each well. Wells are then gently washed three times with 1.0 ml of media and final resuspended in 1.0 ml media. The enrichment for adherent cells generally yields 2.5-3.0 x 10 5 cells per well. The addition of test compounds, LPS, cell incubation conditions and processing of supernatants proceeds as described above. ELISA: Quantikine kits (R&D Systems) may be used for the measurement of mature IL-lβ. Assays are performed according to the manufacturer's directions. Mature IL-lβ - 64 - levels of about 1-3 ng/ml in both PBMC and adherent mononuclear cell positive controls are observed. ELISA assays are performed on 1:5, 1:10 and 1:20 dilutions of supernatants from LPS-positive controls to select the optimal dilution for supernatants in the test panel. The inhibitory potency of the compounds can be represented by an IC50 value, which is the concentration of inhibitor at which 50% of mature IL-lβ is detected in the supernatant as compared to the positive controls. The skilled practitioner realizes that values obtained in cell assays may depend on multiple factors. The values may not necessarily represent fine quantitative results. Example 3 Whole Blood Assay for IL-lβ Production Whole blood assay IC50 values for compounds of this invention were obtained using the method described below: Purpose : The whole blood assay is a simple method for measuring the production of IL-lβ (or other cytokines) and the activity of potential inhibitors. The complexity of this assay system, with its full complement of lymphoid and inflammatory cell types, spectrum of plasma proteins and red blood cells is an ideal in vitro representation of human in vivo physiologic conditions. Materials : Pyrogen-free syringes (~ 30 cc) Pyrogen-free sterile vacuum tubes containing lyophilized Na 2 EDTA (4.5 mg/l0 ml tube) Human whole blood sample (~ 30-50 cc) 1.5 ml Eppendorf tubes - 65 - Test compound stock solutions (~ 25mM in DMSO or other solvent) Endotoxin-free sodium chloride solution (0.9%) and HBSS Lipopolysaccharide (Sigma; Cat . # L-3012) stock solution at lmg/ml in HBSS IL-lβ ELISA Kit (R & D Systems; Cat # DLB50) TNFα ELISA Kit (R & D Systems; Cat # DTA50) Water bath or incubator Whole Blood Assay Experimental Procedure: Set incubator or water bath at 30 °C. Aliquot 0.25 ml of blood into 1.5 ml Eppendorf tubes. Note: be sure to invert the whole blood sample tubes after every two aliquots. Differences in replicates may result if the cells sediment and are not uniformly suspended. Use of a positive displacement pipette will also minimize differences between replicate aliquots. Prepare drug dilutions in sterile pyrogen-free saline by serial dilution. A dilution series which brackets the apparent Kj_ for a test compound determined in an ICE inhibition assay is generally used for the primary compound screen. For extremely hydrophobic compounds, prepare compound dilutions in fresh plasma obtained from the same blood donor or in PBS-containing 5% DMSO to enhance solubility. Add 25 μl test compound dilution or vehicle control and gently mix the sample. Then add 5.0 μl LPS solution (250 ng/ml stocked prepared fresh: 5.0 ng/ml final concentration LPS) , and mix again. Incubate the tubes at 30 °C in a water bath for 16-18 hr with occasional mixing. Alternatively, the tubes can be placed in a rotator set at 4 rpm for the same incubation period. This assay should be set up in duplicate or triplicate with the following controls: negative control - no LPS; positive control - no test inhibitor; vehicle - 66 - control - the highest concentration of DMSO or compound solvent used in the experiment. Additional saline is added to all control tubes to normalize volumes for both control and experimental whole blood test samples . After the incubation period, whole blood samples are centrifuged for 10 minutes at ~ 2000 rpm in the microfuge, plasma is transferred to a fresh microfuge tube and centrifuged at 1000 x g to pellet residual platelets if necessary. Plasma samples may be stored frozen at -70 °C prior to assay for cytokine levels by ELISA. ELISA: R & D Systems (614 McKinley Place N.E. Minneapolis, MN 55413) Quantikine kits may be used for measurement of IL-lβ and TNF-α. The assays are performed according to the manufacturer's directions. IL-lβ levels of ~ 1-5 ng/ml in positive controls among a range of individuals may be observed. A 1:200 dilution of plasma for all samples is usually sufficient for experiments for ELISA results to fall on the linear range of the ELISA standard curves . It may be necessary to optimize standard dilutions if you observe differences in the whole blood assay. Nerad, J.L. et al . , J. Leukocyte Biol. , 52, pp. 687-692 (1992). Example 4 The antiviral efficacy of compounds may be evaluated in various in vitro and in vivo assays . For example, compounds may be tested in in vitro viral replication assays. In vitro assays may employ whole cells or isolated cellular components. In vivo assays include animal models for viral diseases. Examples of such animal models include, but are not limited to, rodent models for HBV or HCV infection, the Woodchuck - 67 - model for HBV infection, and chimpanzee model for HCV infection. Compounds of this invention may also be evaluated in animal models for dietary alcohol-induced disease.
