Description: TITLE CYCLIC β-AMINO ACID DERIVATIVES AS INHIBITORS OF MATRIX METALLOPROTEASES AND TNF-α ' FIELD OF THE INVENTION This invention relates generally to novel cyclic β- a ino acid derivatives as matrix metalloproteases and. TNF-α inhibitors, pharmaceutical compositions containing the same, and methods of using the same. BACKGROUND OF THE INVENTION There is now a body of evidence that metalloproteases (MP) are important in the uncontrolled breakdown of connective tissue, including proteoglycan and collagen, leading to resorption of the extracellular matrix. This is a feature of many pathological conditions, such as rheumatoid and osteoarthritis, corneal, epidermal or gastric ulceration; tumor metastasis or invasion; periodontal disease and bone disease. Normally these catabolic enzymes are tightly regulated at the level of their synthesis as well as at their level of extracellular activity through the action of specific inhibitors, such as alpha-2- macroglobulins and TIMPs (tissue inhibitors of mefalloprotease) , which form inactive complexes with the MP's. Osteo- and Rheumatoid Arthritis (OA and RA respectively) are destructive diseases of articular cartilage characterized by localized erosion of the cartilage surface. Findings have shown that articular cartilage from the femoral heads of patients with OA, for example, had a reduced incorporation of radiolabeled sulfate over controls, suggesting that there must be an enhanced rate of cartilage degradation in OA (Mankin et al . J. Bone Joint Surg. 52A, 1970, 424-434) . There are four classes of protein degradative enzymes in mammalian cells: serine, cysteine, aspartic and metalloproteases. The available evidence supports that it is the metalloproteases which are responsible for the degradation of the extracellular matrix of articular cartilage in OA and RA. Increased activities of collagenases and stromelysin have been found in OA cartilage and the activity correlates with severity of the lesion (Mankin et al . Arthritis Rheum. 21, 1978, 761-766, oessner et al . Arthritis Rheum. 26, 1983, 63-68 and Ibid. 27, 1984, 305-312). In addition, aggrecanase has been identified as providing the specific cleavage product of proteoglycan found in RA and OA patients (Lohmander L.S. et al. Arthritis Rheum. 36, 1993, 1214-22). Therefore, metalloproteases (MP) have been implicated as the key enzymes in the destruction of mammalian cartilage and bone. It can be expected that the pathogenesis of such diseases can be modified in a beneficial manner by the administration of MP inhibitors, and many compounds have been suggested for this purpose (see ahl et al . Ann. Rep. Med. Chem. 25, 175-184, AP, San Diego, 1990) . Tumor necrosis factor (TNF) is a cell-associated cytokine that is processed from a 26kd precursor form to a 17kd active form. TNF has been ' shown to be a primary mediator in humans and in animals, of inflammation, fever, and acute phase responses, similar to those observed during acute infection and shock. Excess TNF has been shown to be lethal. There is now considerable evidence that blocking the effects of TNF with specific antibodies can be beneficial in a variety of circumstances including autoimmune diseases such as rheumatoid arthritis (Feldman et al, Lancet, 1994, 344, 1105) and non-insulin dependent diabetes melitus. (Lohmander L.S. et al . Arthritis Rheum. 36, 1993, 1214-22) and Crohn's disease (MacDonald T. et al . Clin. Exp. Immunol. 81, 1990, 301). Compounds which inhibit the production of TNF are therefore of therapeutic importance for the treatment of inflammatory disorders. Recently, TNF-α converting enzyme (TACE) , the enzyme responsible for TNF-α release from cells, were purified and sequenced (Black et al Nature 1997, 385, 729; Moss et al Nature 1997, 385, 733) . This invention describes molecules that inhibit this enzyme and hence the • secretion of active TNF-α from cells. These novel molecules provide a means of mechanism based therapeutic intervention for diseases including but not restricted to septic shock, haemodynamic shock, sepsis syndrome, post ischemic reperfusion injury, malaria, Crohn's disease, inflammatory bowel diseases, mycobacterial infection, meningitis, psoriasis, congestive heart failure, fibrotic diseases, cachexia, graft rejection, cancer, diseases involving angiogenesis, autoimmune diseases, skin inflammatory diseases, OA, RA, multiple sclerosis, radiation damage, hyperoxic alveolar injury, periodontal disease, HIV and non- insulin dependent diabetes melitus. Since excessive TNF production has been noted in several disease conditions also characterized by MMP- mediated tissue degradation, compounds which inhibit both MMPs and TNF production may also have a particular advantage in diseases where both mechanisms are involved. EP 0,780,286 describes MMP inhibitors of formula A: A wherein Y can be NHOH, R 1 and R 2 can combine to form a cycloalkyl or heterocyclo alkyl group, R 3 and R 4 can be a variety of groups including H, and R 5 can be substituted aryl . WO 97/20824 depicts MMP inhibitors of formula B: B wherein ring V contains six atoms, Z is 0 or S, and Ar is an aryl or heteroaryl group. Ar is preferably a monocyclic aryl group with an optional para substituent or an unsubstituted monocyclic heteroaryl group. EP 0,818,442 illustrates MMP inhibitors of formula C: c wherein Ar is optionally substituted phenyl or naphthyl, Z can be absent and X and Y can be a variety of substituents . Compounds of this sort are not considered to be part of the present invention. The compounds of the present invention act as inhibitors of MPs, in particular TNF-α, MMPs, and/or aggrecanase. These novel molecules are provided as anti- inflammatory compounds and cartilage protecting therapeutics. The inhibition of aggrecanase, TNF-C, and other metalloproteases by molecules of the present invention indicates they are anti-inflammatory and should prevent the degradation of cartilage by these enzymes, thereby alleviating the pathological conditions of OA and RA. SUMMARY OF THE INVENTION Accordingly, one object of the present invention is to provide novel cyclic hydroxamic acids useful as metalloprotease inhibitors or pharmaceutically acceptable salts or prodrugs thereof . It is another object of the present invention to provide pharmaceutical compositions comprising a pharmaceutically acceptable carrier and a therapeutically effective amount of at least one of the compounds of the present invention or a pharmaceutically acceptable salt or prodrug form thereof. It is another object of the present invention to provide a method for treating inflammatory disorders, comprising: administering to a host, in need of such treatment, a therapeutically effective amount of at least one of the compounds of the present invention or a pharmaceutically acceptable salt or prodrug form thereof. It is another object of the present invention to provide novel compounds of the present invention for use in therapy. It is another object of the present invention to provide the use of novel compounds of the present invention for the manufacture of a medicament for the treatment of a condition or disease mediated by MMPs, TNF, aggrecanase, or a combination thereof.

DEFINITIONS The compounds herein described may have asymmetric centers . Compounds of the present invention containing an asymmetrically substituted atom may be isolated in optically active or racemic forms. -It is well known in the art how to prepare optically active forms, such as by resolution of racemic forms or by synthesis from optically active starting materials. Geometric isomers of double bonds such as olefins and C=N double bonds can also be present in the compounds described herein, and all such stable isomers are contemplated in the present invention. Cis and trans geometric isomers of the compounds of the present invention are described and may be isolated as a mixture of isomers or as separated isomeric forms. All chiral, diastereomeric, racemic forms and all geometric isomeric forms of a structure are intended, unless the specific stereochemistry or isomeric form is specifically indicated. All processes used to prepare compounds of the present invention and intermediates made therein are considered to be part of the present invention. The term "substituted," as used herein, means that any one or more hydrogens on the designated atom is replaced with a selection from the indicated group, provided that the designated atom's normal valency is not exceeded, and that the substitution results in a stable compound. When a substituent is keto (i.e., =0), then 2 hydrogens on the atom, are replaced. Keto substituents are not present on aromatic moieties.

When any variable (e.g., R^) occurs more than one time in any constituent or formula for a compound, its definition at " each occurrence is independent of its definition at every other occurrence. Thus, for example, if a group is shown to be substituted with 0-2 R 6 , then said group may optionally be substituted with up to two R 6 groups and R 6 at each occurrence is selected independently from the definition of R 6 . Also, combinations of substituents and/or variables are permissible only if such combinations result in stable compounds . When a bond to a substituent is shown to cross a bond connecting two atoms in a ring, then such substituent may be bonded to any atom on the ring. When a substituent is listed without indicating the atom via which such substituent is bonded to the rest of the compound of a given formula, then such substituent may be bonded via any atom in such substituent.

Since prodrugs are known to enhance numerous desirable qualities of pharmaceuticals (e.g., solubility, bioavailability, manufacturing, etc ... ) the compounds of the present invention may be delivered in prodrug form. Thus, the present invention is intended to cover prodrugs of the presently claimed compounds, methods of delivering the same_ and compositions containing the same. "Prodrugs" are intended to include any covalently bonded carriers which release an active parent drug of the present invention in vivo when such prodrug is administered to a mammalian subject. Prodrugs the present invention are prepared by modifying functional groups present in the compound in such a way that the modifications are cleaved, either in routine manipulation or in vivo, to the parent compound. Prodrugs include compounds of the present invention wherein a hydroxy, amino, or sulfhydryl group is bonded to any group that, when the prodrug of the present invention is administered to a mammalian subject, it cleaves to form a free hydroxyl, free amino, or free sulfhydryl group, respectively. Examples of prodrugs include, but are not limited to, acetate, formate and benzoate derivatives of alcohol and amine functional groups in the compounds of the present invention. - "Stable compound" and "stable structure" are meant to indicate a compound that is sufficiently robust to survive isolation to a useful degree of purity from a reaction mixture, and formulation into an efficacious therapeutic agent . "Therapeutically effective amount" is intended to include an amount of a compound of the present invention or an amount of the combination of compounds claimed effective to inhibit a desired metalloprotease in a host. The combination of compounds is preferably a synergistic combination. Synergy, as described for example by Chou and Talalay, Adv. Enzyme Regul. 22:27-55 (1984), occurs when the effect (in this case, inhibition of the desired target) of the compounds when administered in combination is greater than the additive effect of the compounds when administered alone as a single agent. In general, a synergistic effect is most clearly demonstrated at suboptimal concentrations of the compounds. Synergy can be in terms of lower cytotoxicity, increased antiviral effect, or some, other beneficial effect of the combination compared with the individual components .

Hydrogenolysis gives amino acid ester 18. 18 is coupled with acid 20 to provide 21 with R 1 as H. To prepare analogues of 21 when R 1 is not a hydrogen, 18 is first converted to 19 by alkylation or reductive amination, then coupled with 20. The pyrrolidine nitrogen in 21 is unmasked and functionalized to various tertiary amines, amides, carbamides, ureas, sulfonamides and sulfonyl ureas following procedures well known in the literature.

Ester 33 is converted to hydroxamic acid following sequence outlined in Scheme 1. Regio-isomers of 33 with piperidine nitrogen transposed to other positions are prepared following a similar sequence. The antipode of 33 can be prepared using the S enantiomer of 26. The trans- iso er of 33 is prepared by epi erization of 31 or 33 under basic conditions (e.g., DBU, PhMe, at reflux).

Commun . 1982, 12, 989 and Wang, W.-B.; Roskamp, E. J. J. Org . Chem. 1992, 57, 6101) . β-Lactam is formed under Mitsunobu conditions (Mitsunobu, 0. Synthesis, 1981, 1) . Opening " of lactam 47 with methylamine followed by N-formylation provide 49. The N-methyl amide moiety of 49 is converted to carboxylic acid by nitrosation with N204 or NaN02, and hydrolysis with LiOOH (Evans, D. A.; Carter, P. H.; Dinsmore, C. J. ; Barrow, J. C . ; Katz, J.

Intermediate 60, available from schemes described previously, is converted to phenol 61 by hydrogenolysis . Phenol 61 is used as common intermediates for structure diversifi ■cation. Reacti>on of 61 w th R10-X provides 62, an alternative is the reaction of 61 with R -OH under Mitsunobu conditions to produce 62. R 10 can be appended directly to the aromatic ring by converting 61 to an aryl triflate then reaction with an organometallic in the presence of a palladium (0) catalyst to give 63. 61 can also be reacted with acyl halides or isocyanates to afford 66. Biaryl ethers 65 can be produced by treatment of 61 with aryl boronic acids in the presence of a copper catalyst. Esters 62-63 and 65-66 are converted to the hydroxamic acids following the sequences outlined in Scheme 1. Scheme 9 Compounds of formula 76 can be prepared starting from the commercially available 3-hydroxy-2-nitrobenzoic acid 67 (Scheme 10) . Conversion of the carboxylic acid to an ester such as an ethyl ester 68 can be accomplished by refluxing in EtOH/benzene in the presence of sulfuric acid. Ester 68 can be reduced to a saturated cyclohexyl ring 69 by hydrogenation in acidic aqueous solution using a catalyst such as Pt0 2 . Coupling of 69 with a benzoic acid derivative 70 using a coupling agent such as BOP produces the amide derivative 71 as the major diastereomer with a cis, cis- stereochemistry. The hydroxyl group of 71 can- be oxidized using an oxidizing agent such as the Dess-Martin periodinane to give a ketone derivative 72. Reductive amination of 72 with ammonium acetate or a primary amine using a reducing agent such as Na(OAc) 3 BH affords the amino derivative 73. After Boc protection at the amino using di-tert-butyl- dicarbonate, saponification of the ethyl ester 74 at an elevated temperature using a base such as KOH in MeOH/H 2 0 followed by coupling of the resulting carboxylic acid with hydroxylamine hydrochloride using a coupling agent such as BOP produces the hydroxamic acid 75. Removal of the Boc group using an acid such TFA/CHC1 2 or 4 N HCI in dioxane affords the final compounds of formula 76. Scheme 10 Compounds of formula 78 can be obtained by reductive amination of the intermediate 73 with an aldehyde using a reducing agent such as Na(OAc) 3 BH followed by conversion of the ethyl ester to a hydroxamate as shown in Scheme 11. Scheme 11 Compounds of formula 80 can be obtained by reductive amination of the intermediate 72 with a cycloamine such as azetidine, pyrrolidine, piperidine or morpholine using a reducing agent such as Na(OAc) 3 BH followed by conversion of the ethyl ester to a hydroxamate as shown in Scheme 12. Scheme 12 Compound of formula 89 can be synthesized starting from the intermediate 69 which is coupled with 4-benzyloxybenzoic acid 81 using a coupling agent such as BOP, producing 82 as the major diastereomer with a cis, cis-stereochemistry (Scheme 13) . The hydroxyl group can be converted to a sulfonate such as a mesylate 83. Displacement of 83 with sodium azide produces the azido derivative 84 which is subjected to a hydrogenolysis using a catalyst such as Pd-C to give the primary amine 85. Mono Boc protection at the amino group is accomplished by reaction of 85 with di-tert- butyl-dicarbonate in THF/H 2 0 using a mixed base such as NaOH/NaHC0 3 . Alkylation of 86 with 4-chloromethyl-2- methylquinoline using a base such as potassium carbonate in acetone at reflux affords the intermediate 87. Following saponification using a base such as KOH in MeOH/H 2 0 at an elevated temperature, the resulting carboxylic acid 88 is coupled with hydroxylamine hydrochloride using a coupling agent such as BOP. Removal of the Boc group using an acid such as TFA/CH 2 C1 2 produces the final compound 89. Scheme 13 Compounds of formula 92 can be prepared starting from the intermediate 87 (Scheme 14) . Saponification using a base such as KOH in MeOH at an elevated temperature followed by deprotection of the Boc group using an acid such as TFA in CH 2 C1 2 produces the amino-carboxylic acid intermediate 90. Reductive amination of 90 with a ketone using a reducing agent such as Na(OAc) 3 BH produces the secondary amine 91. The hydroxamic acids of formula 92 can be obtained by coupling the carboxylic acid with hydroxylamine hydrochloride using a coupling agent such as BOP. Scheme 14 Compounds of formula 95 can be obtained by reductive amination of the intermediate 90 with an aldehyde using a reducing agent such as Na(OAc) 3 BH followed by conversion of the carboxylic acid to a hydroxamic acid as shown in Scheme 15. Scheme 15 Compounds of formula 103 can be prepared starting from the intermediate 85 (Scheme 16) . The mono-benzylated amino derivative 97 can be obtained by reductive amination of the intermediate 85 with excess benzaldehyde using a reducing agent such as Na(OAc) 3 BH followed by hydrogenation under atmospheric pressure using a catalyst such as Pd-C. Further alkylation at the benzylamino group by reductive amination with an aldehyde using a reducing agent such as Na(0Ac) 3 BH produces the tertiary amino derivative 98. After removal of the benzyl group by hydrogenation, the secondary amine is protected by reaction with di-tert-butyl-dicarbonate. Alkylation of the phenol derivative 100 with 4-chloromethyl- 2-methylquinoline is followed by saponification of the ethyl ester using a base such as KOH in MeOH at reflux. Conversion of the carboxylic acid to a hydroxamic acid followed by acid deprotection of the Boc group affords compounds of formula 103. Scheme 16 Compounds of formula 108 can be prepared starting from the intermediate 83 (Scheme 17) . Displacement of 83 with ArOH produces the aryl ether 104. After removal of the benzyl group by hydrogenation using a catalyst such as Pd-C, the phenol moiety is alkylated with 4-chloromethyl-2- methylquinoline. Saponification of the ethyl ester using a base such as KOH in MeOH at reflux followed by coupling of the resulting carboxylic acid with hydroxylamine hydrochloride using a coupling agent such as BOP affords compounds of formula 108. Scheme 17 The 3-hydroxyl analog of formula 110 can be prepared starting from the intermediate 71. Saponification using a base such as iOH followed by coupling the resulting carboxylic acid with hydroxylamine hydrochloride using a coupling agent such as BOP provides the the final product with a cis, cis-stereochemistry. Scheme 18 The cis-trans-diastereomeric analog of 110 can be ' prepared starting from the same intermediate 71. Inversion of the chirality at the 3-hydroxyl position can be accomplished by a Mitsunobu reaction with 4-nitrobenzoic acid. Hydrolysis using a base such as KOH removes the 4- nitrobenzoyl moiety and saponifies the ethyl ester. Coupling of the resulting carboxylic acid with hydroxylamine hydrochloride using a coupling agent such as BOP provides compound of formula 112. Scheme 19 A series of compound of formula (I) where ring B is tetrahydropyran are prepared following the sequence outlined in Scheme 20. Treatment of the enolate of tetrahydropyranone 113 with Mander's reagent provides β-keto ester 114. Condensation of 114 with amine 115 gives enamine 116. Reduction of 116 with sodium (triacetoxy)borohydride proceeds stereoselectively to give desired amine 11 . Hydrogenolysis and coupling with acid 20 provides ester 119. Ester 119 is converted to hydroxamic acid following sequence outline in Scheme 1. Sche e 20 Compounds of formula (I) wherein ring B is a -tetera-hydrofuran are prepared as outlined in Schemes 21 and 22. Michael addition of the sodium salt of methyl glycolate 120 to methyl acrylate and concomitant Dieckman cyclization provides the keto-ester 121. Enamine formation with (R) -α- methylbenzyl amine 115 and diastereoselective" reduction gives 123. Hydrogenolysis gives the amino acid "ester 124. 124 is coupled to acid 20 and converted to the hydroxamate 126. Scheme 21 H a a BOP Reagent U Y DIPEA 124 20 123 125 126 An alternative preparation (Scheme 22) of the amino acid ester 124 begins with the intermediate 121. Enamine formation with NHOAc and acetylation gives 128. Asymmetric hydrogenation using a chiral rhodium catalyst (J " . Am . Chem . Soc . 1995, 117, 9375) arid de-acetylation would yield 124 that could be converted similarly to hydroxamate 126. Scheme 22 121 127 128 Another procedure for the synthesis of cyclic β-amino acids useful for the preparation of compounds of formula I uses the well documented [2+2] cycloaddition of chlorosulfonylisocyanate with olefins (Scheme 23, Dhar, D.N.; Murthy, K.S.K. Synthesis 1986, 437-449). When 130 is reacted with chlorosulfonylisocyanate the resulting β-lactam intermediate 131 can be opened to afford cyclic β-amino acids using a variety of conditions, but most conveniently with chlorotrimethylsilane/methanol . The methyl ester 13 can then be converted to compounds of formula I followed our usual procedure of attaching carboxcylic acid 20 to provide 132 then hydroxamic acid 133 is formed by our standard conditions . The trans β-amino acids 134 are available by equilibration of cis amide ester 132 under basic conditions . Scheme 23 An alternative synthesis of 133 begins with formation of benzyl hydroxamate 136 from trans β-hydroxy carboxylate 135 (Scheme 24) . Intramolecular cyclization of 136 under Mitsunobu conditions (Bellettini, J.R.; Miller, M.J. Tetrahedron Letters 1997, 38, 167-168) then affords benzyl protected hydroxy β-lactam 137. Removal of the benzyl group by hydrogenolysis and reduction of the intermediate N- hydroxy β-lactam provides 131, which can be converted to final products as shown in the previous scheme. Scheme 24 131 A synthesis of cyclic lactam β-amino acids begins conveniently with ketone 138 (Scheme 25) . Oxime 139 is formed with hydroxylamine hydrochloride, sodium bicarbonate in refluxing methanol and is then treated with p- toluenesulfonyl chloride to give Beckmann rearrangement precursor 140. The rearrangement can be driven by a variety of conditions with silica gel/chloroform providing a straightforward mild procedure,. to form lactam 141. Conversion of 141 to hydroxamate 142 uses conditions outline in previous schemes . Scheme 25 Compounds of formula 147 can be prepared using the protocol described in Scheme 26. Alkylation of methyl 4- aminobenzoate or methyl 4-methylaminobenzoate 143 with 4- chloromethyl-2-methylquinoline using K 2 C0 3 in DMF at 100 ϋ C produced the secondary or tertiary amine 144. Following saponification, the resulting carboxylic acid 145 was coupled with a cyclic β-aminoacid derivative using a coupling agent such as BOP to give the amide 146. Conversion of the ester in 146 to a hydroxamic acid using hydroxylamine afforded the final product 147. Scheme 26 R=H, Me Compounds of formula 154 can be prepared according to Scheme 27. An aldehyde 148 was treated with hydroxylamine to provide an oxime 149. Cycloaddition of 149 with an olefin 150 using bleach produced the isoxazoline derivative 151. Hydrolysis of the ester followed by coupling with a cyclic β-aminoacid derivative afforded the amide ' 153. Treatment of 153 with a hydroxylamine solution produced the hydroxamic acid 154. Scheme 27 R 1 =aryl, heteroaryl, alkyl, carbocycle, heterocycle Compounds of formula 161 can be prepared using the sequence as illustrated in Scheme 28. An aldehyde 155 was treated with hydroxylamine to give an oxime 156. Cycloaddition of 146 with an olefin 157 using bleach produced the isoxazoline derivative 158. Following saponification, the resulting carboxylic acid 159 was condensed with a cyclic β-aminoacid to give the amide 160. Treatment of 160 with a hydroxylamine solution afforded the hydroxamic acid 161. Scheme 28 158 159 R 1 =aryl, heteroaryl, alkyl, carbocycle, heterocycle One diastereomer of a compound of Formula I may display superior activity compared with the others. Thus, the following stereochemistries are considered to be a part of the present invention. When required, separation of the racemic material can be achieved by HPLC using a chiral column or by a resolution using a resolving agent such as camphonic chloride as in Steven D. Young, et al, Antimicrobial Agents and Chemotheraphy , 1995, 2602-2605. A chiral compound of Formula I may also be directly synthesized using a chiral catalyst or a chiral ligand, e.g., Andrew S.

Metalloproteases have also been implicated in the degradation of basement membranes to allow infiltration of cancer cells into the circulation and subsequent penetration into other tissues leading to tumor metastasis (Stetler- Stevenson, Cancer and Metastasis Reviews, 9, 289-303, 1990).

Aggrecanase Enzymatic Assay A novel enzymatic assay was developed to detect potential inhibitors of aggrecanase. The assay uses active aggrecanase accumulated in media from stimulated bovine nasal cartilage (BNC) or related cartilage sources and purified cartilage aggrecan monomer or a fragment thereof as a substrate. The substrate concentration, amount of aggrecanases time of incubation and amount of product loaded for Western analysis were optimized for use of this assay in screening putative aggrecanase inhibitors . Aggrecanase is generated by stimulation of cartilage slices with interleukin-1 (IL- 1), tumor necrosis factor alpha (TNF-α) or other stimuli. Matrix metalloproteases (MMPs) are secreted from cartilage in an inactive, zymogen form following stimulation, although active enzymes are present within the matrix. We have shown that following depletion of the extracellular aggrecan matrix, active MMPs are released into the_ culture media (Tortorella, M.D. et. al . Trans. Ortho. ,Resr ~ Soc. 20, 341, 1995) . Therefore, in order to accumulate BNC aggrecanase in culture media, cartilage is first depleted of endogenous aggrecan by stimulation with 500 ng/ml human recombinant IL- β for 6 days with media changes every- 2- days. Cartilage is then stimulated for an additional 8 days without media change to allow accumulation of soluble, active aggrecanase in the culture media. In order to decrease the amount of other matrix metalloproteases released into the media during aggrecanase accumulation, agents which inhibit MMP-1, -2, - 3, and -9 biosynthesis are included during stimulation. This BNC conditioned media, containing aggrecanase activity is then used as the source of aggrecanase for the assay. - Aggrecanase enzymatic activity is detected by monitoring production of aggrecan fragments produced exclusively by cleavage at the Glu373-Ala374 bond within the aggrecan core protein by Western analysis using the monoclonal antibody, -BC-3 (Hughes, CE, et al . , Biochem J 306:799-804, 1995). This antibody recognizes aggrecan fragments with the N- terminus, 374ARGSVIL, generated upon cleavage by aggrecanase. The BC-3 antibody recognizes this neαepitope only when it is at the N-terminus and not when it is present internally within aggrecan fragments or within the aggrecan protein core. Other proteases produced by cartilage in response to IL-1 do not cleave aggrecan at the Glu373-Ala374 aggrecanase site; therefore, only products produced upon cleavage by aggrecanase are detected. Kinetic studies using this assay yield a Km of 1.5 +/- 0.35 uM for aggrecanase. To evaluate inhibition of aggrecanase, compounds are prepared as 10 mM stocks in DMSO, water or other solvents and diluted to appropriate concentrations in water. Drug (50 ul) is added to 50 ul of aggrecanase-containing media and 50 ul of 2 mg/ml aggrecan substrate and brought to a final volume of 200 ul in 0.2 M Tris, pH 7.6, containing 0.4 M NaCl and 40 mM CaCl 2 . The assay is run for 4 hr at 37°C, quenched with 20 mM EDTA and analyzed for aggrecanase- generated products . A sample containing enzyme and substrate without drug is included as a positive control and enzyme incubated in the absence of substrate serves as a measure of background. Removal of the glycosaminoglycan side chains from aggrecan is necessary for the Ϊ3C-3 antibody to recognize the ARGSVIL epitope on the core protein. Therefore, for analysis of aggrecan fragments generated by cleavage at the Glu373-Ala374 site, proteoglycans and proteoglycan fragments are enzymatically deglycosylated with chondroitinase ABC (0.1 units/10 ug GAG) for 2 hr at 37°C and then with keratanase (0.1 units/10 ug GAG) and keratanase II (0.002 units/10 ug GAG) for 2 hr at 37°C in buffer containing 50 mM sodium acetate, 0.1 M Tris/HCl, pH 6.5. After digestion, aggrecan in the samples is precipitated with 5 volumes of acetone and resuspended in 30 ul of Tris glycine SDS sample buffer (Novex) containing 2.5% beta mercaptoethanol . Samples are loaded and then separated by SDS-PAGE under reducing conditions with 4-12% gradient gels, transferred to nitrocellulose and immunolocated with 1:500 dilution of antibody BC3. Subsequently, membranes are incubated with a 1:5000 dilution of goat anti-mouse IgG alkaline phosphatase second antibody and aggrecan catabolites visualized by incubation with appropriate substrate for 10-30 minutes to achieve optimal color development. Blots are quantitated by scanning densitometry and inhibition of aggrecanase determined by comparing the amount of product produced in the presence versus absence of compound. TNF PBMC ASSAY Human peripheral blood mononuclear cells (PBMC) were obtained from normal donor blood by leukophoresis and isolated by Ficoll-Paque density separation. PBMCs were suspended in .5ml RPMI 1640 with no serum at 2 x 10 6 cells/ml in 96 well polystyrene plates. Cells were preincubated 10 minutes with compound, then stimulated with 1 μg/ml LPS (Lipopolysaccharide, Salmonella typhimurium) to induce TNF production. After an incubation of 5 hours at 37°C in 95% air, 5% CO 2 environment, culture supernatants were removed and tested by standard sandwich ELISA for TNF production. TNF Human Whole Blood Assay Blood is drawn from normal donors into tubes containing 143 USP units of heparin/lOml . 225ul of blood is plated directly into sterile polypropylene tubes. Compounds are diluted -i-n DMSO/serum free media and added to the blood samples so the final concentration of compounds are 50, 10, 5, 1, .5, .1, and .01 μM. The final concentration of DMSO does not exceed .5%. Compounds " "are preincubated for 15 minutes before the addition of lOOng/ml LPS. Plates are incubated for 5 hours in an atmosphere of 5% CO 2 in air. At the end of 5 hours, 750ul of serum free media is added to each tube and the samples are spun at 1200RPM for 10 minutes. The supernatant is collected off -the top and assayed for TNF-alpha production by a " standard sandwich ELISA. The ability of compounds to inhibit TNF-alpha production by 50% compared to DMSO treated cultures is given by the IC50 value. TNF Induction In Mice Test compounds are administered to mice either I. P. or P.O. at time zero. Immediately following compound administration, mice receive an I. P. injection of 20 mg of D-galactosamine plus 10 μg of lipopolysaccharide. One hour later, animals are anesthetized and bled by cardiac puncture. Blood plasma is evaluated for TNF levels by an ELISA specific for mouse TNF. Administration of representative compounds of the present invention to mice results-in a dose-dependent suppression of plasma TNF levels at one hour in the above assay. MMP ASSAYS The enzymatic activities of recombinant MMP-1, 2, 3, 7, 8, 9, 13, 14, 15, and 16 were measured at 25°C with a - fluorometric assay (Copeland, R.A.; Lombardo, D.; Giannaras, J. and Decicco, C.P. Bioorganic Med. Chem . Lett . 1995,. 5 , 1947-1952) . Final enzyme concentrations in the assay were between 0.05 and 10 nM depending on the enzyme and the potency of the inhibitor tested.- The permisive peptide substrate, MCA-Pro-Leu-Gly-Leu-DPA-Ala-Arg-NH 2 , was present at a final concentration of 10 uM in all assays. Initial velocities, in the presence or absence of inhibitor, were measured as slopes of the linear portion of the product progress curves. IC50 values were determined by plotting the inhibitor concentration dependence of the fractional velocity for each enzyme, and fitting the data by non-linear least squares methods to the standard isotherm equation (Copeland, R.A. Enzymes : A practical Introduction to Structure, Mechanism and Data Analysis, Wiley-VHC, New York, 1996, pp 187-223) . All of the compounds studied here were assumed to act as " competitive inhibitors of the enzyme, binding to the active site Zn atom as previously demonstrated by crystallographic studies of MMP-3 complexed with related hydroxamic acids (Rockwell, A.; Melden, M. ; Copeland, R.A. ; Hardman, K. ; Decicco, C.P. and DeGrado, W.F. J. Am. Chem. Soc . 1996, 118, 10337-10338) . Based on the assumption of competitive inhibiton, the IC50 values were converted to Ki values as previously described. Compounds tested in the above assay are considered to be active if they exhibit a Ki of <10 μM. Preferred compounds of the present invention have Ki's of <1 μM. More preferred compounds of the present invention have Ki's of <0.1 μM. Even more preferred compounds of the present invention have Ki's of <0.01 μM. Still. more preferred compounds of the present invention have Ki's of <0.001 μM. Using the methodology described above, a number of compounds of the present invention were found to exhibit Ki's of <10 μM, thereby confirming the utility of the compounds of the present " invention. Dosage and Formulation The compounds of the present invention can be administered orally using any pharmaceutically acceptable dosage form known in the art for such administration. The active ingredient can be supplied in solid dosage forms such as dry powders, granules, tablets or capsules, or in liquid dosage forms, such as syrups or aqueous suspensions. The active ingredient can be administered alone, but is generally administered with a pharmaceutical carrier. A valuable treatise with respect to pharmaceutical dosage forms is Remington's Pharmaceutical Sciences, Mack Publishing. The compounds of the present invention can be administered in such oral dosage forms as tablets, capsules (each of which includes sustained release or timed release formulations) , pills, powders, granules, elixirs, tinctures, suspensions, syrups, and emulsions. Likewise, they may also be administered in intravenous (bolus or infusion) , intraperitoneal, subcutaneous, or intramuscular form, all using dosage forms well known to those of ordinary skill in the pharmaceutical arts. An effective but non-toxic amount of the compound desired can be employed as an antiinflammatory and antiarthritic agent. The compounds of this invention can be administered by any means that produces contact of the active agent with the agent's site of action in the body of a mammal. They can be administered by any conventional means available for use in conjunction ^ ith pharmaceuticals, either as individual therapeutic agents or in a combination of therapeutic agents. They can be administered alone, but generally administered with a pharmaceutical carrier selected on the basis of the chosen route of administration and standard pharmaceutical practice. The dosage regimen for" * the compounds of the present invention will, of course, vary depending upon known factors, such as the pharmacodynamic characteristics of the particular agent and its mode and route of administration; the species, age, sex, health, medical condition, and weight of the recipient; the nature and extent of the symptoms; the kind of concurrent treatment; the frequency of treatment; the route of administration, the renal and hepatic function of the patient, and the effect desired. An ordinarily skilled physician or veterinarian can readily determine and prescribe the effective amount of the drug required to prevent, counter, or arrest the progress of the condition. By way of general guidance, the daily oral dosage of each active ingredient, when used for the indicated effects, will range between about 0.001 to 1000 mg/kg of body weight, preferably between about 0.01 to 100 mg/kg of body weight per day, and most preferably between about 1.0 to 20 mg/kg/day. For a normal male adult human of approximately 70 kg of body weight, this translates into a dosage of 70 to 1400 mg/day. Intravenously, the most preferred doses will range from about 1 to about 10 mg/kg/minute during a constant rate infusion. Advantageously, compounds of the present invention may be administered in a single daily dose, or the total daily dosage may be administered in divided doses of two, three, or four times daily. The compounds for the present invention can be administered in intranasal form via topical use of suitable intranasal vehicles, or via transdermal routes, using those forms of transdermal skin patches wall known to those of ordinary skill in that art. To be administered in the form of a transdermal delivery system, the dosage administration will, of course, be continuous rather than intermi-ttant throughout the dosage regimen. In the methods of the present invention, the compounds herein described in detail can form the active ingredient, and are typically administered in admixture with suitable pharmaceutical diluents, excipients, or carriers (collectively referred to herein as carrier materials) suitably selected with respect to the intended form of administration, that is, oral tablets, capsules, elixirs, syrups and the like, and consistent with conventional pharmaceutical practices . For instance, for oral administration in the form of a tablet or capsule, the active drug component can be combined with an oral, non-toxic, pharmaceutically acceptable, inert carrier such as lactose, starch, sucrose, glucose, methyl callulose, magnesium stearate, dicalcium phosphate, calcium sulfate, mannitol, sorbitol and the like; for oral administration in liquid form, the oral drug components can be combined with any oral, non-toxic, pharmaceutically acceptable inert carrier such as ethanol, glycerol, water, and the like. Moreover, when desired or necessary, suitable binders, lubricants, disintegrating agents, and coloring agents can also be incorporated into the mixture. Suitable binders include starch, gelatin, natural sugars such as glucose or beta-lactose, corn sweeteners, natural and synthetic gums such as acacia, tragacanth, or sodium alginate, carboxymethylcellulose, polyethylene glycol, waxes, and the like. Lubricants used in these dosage forms include sodium oleate, sodium stearate, magnesium stearate, sodium benzoate, sodium acetate, sodium chloride, and the like. Disintegrators include, without limitation, starch, methyl cellulose, agar, bentonite, xanthan gum, and the like. The compounds of the present invention can also be administered in the form of liposome delivery systems, such as small unilamellar vesicles, large unilamallar vesicles, and multilamellar vesicles . Liposomes can be formed from a variety of phospholipids, such as cholesterol, stearylamine, or phosphatidylcholines . Compounds of the present invention may also be coupled with soluble polymers as targetable drug carriers. Such polymers can include polyvinylpyrrolidone, pyran copolymer, polyhydroxypropylmethacrylamide-phenol , polyhydroxyethylaspartamidephenol, or polyethyleneoxide- polylysine substituted with palmitoyl residues. Furthermore, the compounds of the present invention may be coupled to a class of biodegradable polymers useful in achieving controlled release of a drug, for example, polylactic acid, polyglycolic acid, copolymers of polylactic and polyglycolic acid, polyepsilon caprolactone, polyhydroxy butyric acid, polyorthoesters, ' polyacetals, polydihydropyrans, polycyanoacylates, and crosslinked or amphipathic block copolymers of hydrogels. Dosage forms (pharmaceutical compositions) suitable for administration may contain from about 1 milligram-"to about 100 milligrams of active ingredient per dosage unit. In these pharmaceutical compositions the active ingredient will ordinarily be present in an amount of about 0.5-95% by weight based on the total weight of the composition. The active ingredient can be administered orally in solid dosage forms, such as capsules, tablets, and powders, or in liquid dosage forms, such as elixirs, syrups, and suspensions. It can also be administered parenterally, in sterile liquid dosage forms. Gelatin capsules may contain the active ingredient and powdered carriers, such as lactose, starch, cellulose derivatives, magnesium stearate, stearic acid, and the like. Similar diluents can be used to make compressed tablets . Both tablets and capsules can be manufactured as sustained release products to provide for continuous release of medication over a period of hours. Compressed tablets can be sugar coated or film coated to mask any unpleasant taste and protect the tablet from the atmosphere, or enteric coated for selective disintegration in the gastrointestinal tract. Liquid dosage forms for oral administration can contain coloring and flavoring to increase patient acceptance. In general, water, a suitable oil, saline, aqueous dextrose (glucose) , and related sugar solutions and glycols such as propylene glycol or polyethylene glycols are suitable carriers for parenteral solutions. Solutions for parenteral administration preferably contain a water soluble salt of the active ingredient, suitable stabilizing agents, and if necessary, buffer substances. Antioxidizing agents such as sodium bisulfite, sodium sulfite, or ascorbic acid, either alone or combined, are suitable stabilizing agents. Also used are citric acid and its salts and sodium EDTA. In addition, parenteral solutions can contain preservatives, such as benzalkonium chloride, methyl- or propyl-paraben, and chlorobutanol . Suitable pharmaceutical carriers are described in Remington's Pharmaceutical Sciences, Mack Publishing Company, a standard reference text in this field. Useful pharmaceutical dosage-forms for administration of the compounds of this invention can be illustrated as follows: Capsules Capsules are prepared by conventional procedures so that the dosage unit is 500 milligrams of active ingredient, 100 milligrams of cellulose and 10 milligrams of magnesium stearate. A large number of unit capsules may also prepared by filling standard two-piece hard gelatin capsules each with 100 milligrams of powdered active ingredient, 150 milligrams of lactose, 50 milligrams of cellulose, and 6 milligrams magnesium stearate.

Emulsifiable Paste Wt . % Active Ingredient 30 Tween® 80 and Span® 80 6 Keltrol® 0.5 Mineral Oil 63.5 All the ingredients are carefully mixed together to make a homogenous paste. Soft Gelatin Capsules A mixture of active ingredient in a digestable oil such as soybean oil, cottonseed oil or olive oil is prepared and injected by means of a positive displacement pump into gelatin to form soft gelatin capsules containing 100 milligrams of the active ingredient. The capsules are washed and dried. Tablets Tablets may be prepared by conventional procedures so that the dosage unit is 500 milligrams of active ingredient, 150 milligrams of lactose, 50 milligrams of cellulose and 10 milligrams of magnesium stearate. A large number of tablets may also be prepared by conventional procedures so that the dosage unit was 100 milligrams of active ingredient, 0.2 milligrams of colloidal silicon dioxide, 5 milligrams of magnesium stearate, 275 milligrams of microcrystalline cellulose, 11 milligrams of starch and 98.8 milligrams of lactose. Appropriate coatings may be applied to increase palatability or delay absorption. Injectable A parenteral composition suitable for administration by injection is prepared by stirring 1.5% by weight of active ingredient in 10% by volume propylene glycol and water. The solution is made isotonic with sodium chloride and sterilized. Suspension An aqueous suspension is -prepared for oral administration so that each 5 mL contain 100 mg of finely divided active ingredient, 200 mg of sodium carboxymethyl cellulose,. 5 mg of sodium benzoate, 1.0 g of sorbitol solution, U.S. P., and 0.025 mL of vanillin. The compounds of the present invention may be administered in combination with a second therapeutic agent, especially non-steroidal anti-inflammatory drugs (NSAID's). The compound of Formula I and such second therapeutic agent can be administered separately or as a physical combination in a single dosage unit, in any dosage form and by various routes of administration, as described above. The compound of Formula I may be formulated together with the second therapeutic agent in a single dosage unit (that is, combined together in one capsule, tablet, powder, or liquid, etc.) . When the compound of Formula I and the .second therapeutic agent are not formulated together in a single dosage unit, the compound of Formula I and the second therapeutic agent may be administered essentially at the same time, or in any order; for example the compound of Formula I may be administered first, followed by administration of the second "' agent . When not administered at the same time, preferably the administration of the compound of Formula I and the second therapeutic agent occurs less than about one hour apart, more preferably less than about 5 to 30 minutes apart . Preferably the route of administration of the compound of Formula I is oral. Although it is preferable that the compound of Formula I and the' second therapeutic agent are both administered by the same route (that is, for example, both orally) , if desired, they may each be administered by different routes and in different dosage forms (that is, for example, one component of the combination product may be administered orally, and another component may be administered intravenously) . The dosage of the compound of Formula I when administered alone or in combination with a second therapeutic agent may vary depending upon various factors such as the pharmacodynamic characteristics of the particular agent and its mode and route of administration, the age, health and weight of the recipient, the nature and extent of the symptoms, the kind of concurrent treatment, the frequency of treatment, and the effect desired, as described above. Particularly when provided as a single dosage unit, the potential exists for a chemical interaction between the combined active ingredients. For this reason, when the compound of Formula I and a second therapeutic agent are combined in a single dosage unit they are formulated such that although the active ingredients are combined in a single dosage unit, the physical contact between the active ingredients is minimized (that is, reduced) . For ex-ample, one active ingredient may be enteric coated. By enteric coating one of the active ingredients, it is possible not only to minimize the contact between the combined active ingredients, but also, it is possible to control the release of one of these components in the gastrointestinal tract such that one of these components is not released in the stomach but rather is released in the intestines. One of the active ingredients may also be coated with a sustained- release material which effects a sustained-release throughout the gastrointestinal tract and also serves to minimize physical contact between the combined active ingredients. Furthermore, the sustained-released component can be additionally enteric coated such that the release of this component occurs only in the intestine. Still another approach would involve the formulation of a combination product in which the one component is coated with a sustained and/or enteric release polymer, and the other component is also coated with a polymer such as a low- viscosity grade of hydroxypropyl methylcellulose (HPMC) or other appropriate materials as known in the art, in order to further separate the active components . The polymer coating serves to form an additional barrier to interaction with the other component . These as well as other ways of minimizing contact between the components of combination products of the present invention, whether administered in a single dosage form or administered in separate forms but at the same time by the same manner, will be readily apparent to those skilled in the art, once armed with the present disclosure. The present invention also includes pharmaceutical kits useful, for example, in the treatment or prevention of osteoarthritis or rheumatoid arthritis, which comprise -one or more containers containing a pharmaceutical composition comprising a therapeutically effective amount of a compound of Formula I. Such kits may further include, if desired, one or more of various conventional pharmaceutical kit components, such as, for example, containers with one or more pharmaceutically acceptable carriers, additional containers, etc., as will be readil-y-apparent to those skilled in the art. Instructions, either as inserts or as labels, indicating quantities of the components to be administered, guidelines for administration, and/or guidelines for mixing the components, may also be included in the kit. In the present disclosure it should be understood that the specified materials and conditions are important in practicing the invention but that unspecified materials and conditions are not excluded so long as they do not prevent the benefits of the invention from being realized. Although this invention has been described with respect to specific embodiments, the details of these embodiments are not to be construed as limitations. 'Various equivalents, changes and modifications may be made without departing from the spirit and scope of this invention, and it is understood that such equivalent embodiments are part of this invention.
