Description: Substituted 4-Biarylbutyric and 5-Biarylpentanoic Acid Derivatives as Matrix Metalloprotease Inhibitors Field This invention relates to enzyme inhibitors, and more particularly, to novel matrix metalloprotease-inhibiting 4-Biarylbutyrohydroxamic Acids, 5- Biarylpentanohydroxamic Acids, 5-Biaryl-l-hydroxy-2-pentanones, 6-Biaryl-l- hydroxy-2-hexanones, N-(4-Biarylbutyryl)sulfonamides and N-(5- Biarylpentanoyl)sulfonamides and derivatives thereof. Background The matrix metalloproteases (aka. matrix metalloendo-proteinases or MMPs) are a family of zinc endoproteinases which include, but are not limited to, interstitial collagenase (aka. MMP-1), stromelysin (aka. proteoglycanase, transin, or MMP-3), gelatinase A (aka. 72kDa-gelatinase or MMP-2) and gelatinase B (aka. 95kDa-gelatinase or MMP-9). These MMPs are secreted by a variety of cells including fibroblasts and chondrocytes, along with natural proteinatious inhibitors known as ITMPs (Tissue Inhibitor of MetalloProteinase). All of these MMPs are capable of destroying a variety of connective tissue components of articular cartilage or basement membranes. Each MMP is secreted as an inactive proenzyme which must be cleaved in a subsequent step before it is able to exert its own proteolytic activity. In addition to the matrix destroying effect, certain of these MMPs such as MMP-3 have been implemented as the in vivo activator for other MMPs such as MMP-1 and MMP-9 (A. Ho, H. Nagase, Arch Biochem Biophys., 267, 211-16 (1988); Y. Ogata, J.J. Enghild, H. Nagase, J. Biol. Chem., 267, 3581-84 (1992)). Thus, a cascade of proteolytic activity can be initiated by an excess of MMP-3. It follows that specific MMP-3 inhibitors should limit the activity of other MMPs that are not directly inhibited by such inhibitors. It has also been reported that MMP-3 can cleave and thereby inactivate the endogenous inhibitors of other proteinases such as elastase (P.G.Winyard, Z. Zhang, K. Chidwick, D.R. Blake, R.W. Carrell G., Murphy, FEBS Letts., 279, 1, 91- 94 (1991)). Inhibitors of MMP-3 could thus influence the activity of other destructive proteinases by modifying the level of their endogenous inhibitors. MMP inhibitors may also be useful in the inhibition of other mammalian metalloproteases such as the adamalysin family (or ADAMs) whose members include TNFα converting enzyme (TACE) and ADAM-10, which can cause the release of TNF from cells. A number of diseases or conditions are thought to be mediated by excess or undesired matrix-destroying metallopro tease activity or by an imbalance in the ratio of the MMPs to the TTMPs or through the action of the release of TNF. These include: a) osteoarthritis (Woessner, et al., /. Biochelogical Chem 1984., 259(6), 3633-3638; /. Rheumatol. 1983, 10, 852-860; M. Zafarullah, et al., /. Rheumatol. 1993, 20, 693-697; H.J.

The primary disabling effect of oeteoarthritis (OA), rheumatoid arthritis (RA) and septic arthritis is the progressive loss of articular cartilage and thereby normal joint function. No marketed pharmaceutical agent is able to prevent or slow this cartilage loss, although nonsteroidal antiinflammatory drugs (NSAIDs) 0 have been given to control pain and swelling. The end result of these diseases is total loss of joint function which is only treatable by joint replacement surgery. MMP inhibitors are expected to halt or reverse the progression of cartilage loss and obviate or delay surgical intervention. Proteases are critical elements at several stages in the progression of 5 metastatic cancer. In this process, the proteolytic degradation of structural protein in the basal membrane allows for expansion of a tumor in the primary site, evasion from this site as well as homing and invasion in distant, secondary sites. Also, tumor induced angiogenesis is required for tumor growth and is dependent on proteolytic tissue remodeling. Transfection experiments with various types of 0 proteases have shown that the matrix metalloproteases play a dominant role in "" *' these processes in particular gelatinases A and B (MMP-2 and MMP-9, respectively). For an overview of this field see Biochimica et Biophysica Acta 695 (1983), 177-214; Eur. Respir. J. 7 (1994), 2062-2072; Critical Reviews in Oral Biology and Medicine 4 (1993), 197-250. 5 Furthermore, it has been shown that inhibition of degradation of extracellular matrix by the native matrix metalloprotease inhibitor ITMP-2 (a protein) arrests cancer growth (Cancer Res. 52, 701-708, 1992) and that TIMP-2 inhibits tumor-induced angiogenesis in experimental systems (Science 248, 1408- 1410, 1990). For a review see Annals of the New York Academy of Sciences 1994, 222-232. It was furthermore demonstrated that the synthetic matrix metalloprotease inhibitor batimastat when given intraperitoneally inhibits human colon tumor growth and spread in an orthotopic model in nude mice (Cancer Res. 54, 4726-4728, 1994) and prolongs the survival of mice bearing human ovarian carcinoma xenografts (Cancer Res. 53, 2087-2091, 1993). The use of this and related compounds has been described in WO-A-9321942. There are a number of patents and patent applications claiming the use of metalloproteinase inhibitors for the retardation of metastatic cancer, promoting tumor regression, inhibiting cancer cell proliferation, slowing or preventing of cartilage loss associated with osteoarthritis or for treatment of other diseases as noted above (e.g. WO-A-9519965, WO-A-9519956, WO-A-9519957, WO-A- 9519961, WO-A-9321942, WO-A-9321942, WO-9421625, U.S. Pat. No. 4,599,361; U.S. Pat. No. 5,190,937; EP 0574 758 Al, published December 22, 1993; EP 026 436 Al published August 3, 1988; and EP 0520 573 Al, published December 30, 1992). The preferred compounds of these patents have peptide backbones with a zinc complexing group (hydroxamic acid, thiol, carboxylic acid or phosphinic acid) at one end and a variety of side chains, both those found in the natural amino acids as well as those with more novel functional groups. Such small peptides are often poorly absorbed, exhibiting low oral bioavailability. They are also subject to rapid proteolytic metabolism, thus having short half lives. As an example, batimastat, the compound described in WO-A-9321942, can only be given intraperitoneally. Some recent patents describe the use of hyroxamic acids with sulfonamide or sulfone moieties as backbones. See, for example WO 9807697, EP 818442 or WO 9749679 (representative structures shown below). from WO 9807697 from WO 9749679 from EP 818442 Matrix metalloprotease inhibitors which are derivatives of butyric and pentanoic acids are disclosed in the following published PCT applications: WO 96/15096, WO 97/43237, WO 97/43240, WO 97/43247, WO 97/43239, WO 97/43245, and WO 97/43238. Summary This invention relates to compounds having matrix metalloprotease inhibitory activity and the generalized formula: (T) X A-B-D-E-G . (I) In the above generalized formula (I), (T) X A represents a substituted or unsubstituted aromatic 6-membered ring or heteroaromatic 5 - 6 membered ring containing 1 - 2 atoms of N, O, or S. T represents one or more substituent groups, the subscript x represents the number of such substituent groups, and A represents the aromatic or heteroaromatic ring, designated as the A ring or A unit. When N is employed in conjunction with either S or O in the A ring, these heteroatoms are separated by at least one carbon atom. The substituent group (s) T are independently selected from the group consisting of halogen; alkyl; haloalkylp-haloalkoxy; alkenyl; alkynyl; -(CH2)pQ in which p is 0 or an integer of 1 - 4; -alkenyl-Q in which the alkenyl moiety comprises 2 - 4 carbons; and alkynyl-Q in which the alkynyl moiety comprises 2 - 7 carbons. Q in the latter three groups is selected from the group consisting of aryl, heteroaryl, -CN, -CHO, -NO2, -CO2R 2 , -OCOR 2 , -SOR 3 , -SO2R 3 , -CON(R )2, -Sθ2N(R4)2, -COR 2 , -N(R 4 ) 2 , -N(R )COR 2 , -N(R 2 )Cθ2R 3 , -N(R 2 )CON(R 4 )2, -CHN4, -OR 4 , and -SR 4 . In these formulae R 2 represents H, alkyl, aryl, heteroaryl, arylalkyl, or heteroaryl-alkyl. R3 represents alkyl, aryl, heteroaryl, arylalkyl, or heteroaryl- alkyl. R 4 represents H; alkyl; aryl; heteroaryl; arylalkyl; heteroaryl-alkyl; alkenyl; alkynyl; alkyleneoxy, polyalkyleneoxy, alkylenethio or alkyleneamino terminated with H, alkyl, or phenyl; haloalkyl; lower alkoxycarbonyl; or acyl. When two R 4 groups are situated on a nitrogen, they may be joined by a bond to form a heterocycle, such as, for example, a morpholine, thiomorpholine, pyrrolidine, or piperidine ring. Unsaturation in a moiety which is attached to Q or which is part of Q is separated from any N, O, or S of Q by at least one carbon atom. The A ring may be unsubstituted or may carry up to 2 substituents T. Accordingly, the subscript x is 0, 1, or 2. In the generalized formula (I), B represents a bond or an optionally substituted aromatic 6-membered ring or a heteroaromatic 5 - 6 membered ring containing 1 - 2 atoms of N, O, or S. When B is a ring, it is referred to as the B ring or B unit. When N is employed in conjunction with either S or O in the B ring, these heteroatoms are separated by at least one carbon atom. There may be 0 -2 substituents T on ring B. In the generalized formula (I), D represents in which R 2 is defined as above and each R 2 may be the same or different. In the generalized formula (I), E represents a chain of n carbon atoms bearing m substituents R^, in which the R^ groups are independent substituents, or constitute spiro or nonspiro rings.

Each group R^ is independently selected from the group consisting of: *fluorine; *hydroxyl, with the proviso that a single carbon atom may bear no more than one hydroxyl group; *alkyl; *aryl; *heteroaryl; *arylalkyl; *heteroaryl-alkyl; *alkenyl; *aryl-substituted alkenyl; *heteraryl-substituted alkenyl; *alkynyl; *aryl-substituted alkynyl; *heteroaryl-substituted alkynyl; *-(CH2)tR' 7 / wherein t is 0 or an integer of 1 - 5 and R7 is selected from the group consisting of: *N-phthalimidoyl; *N-(l,2-naphthalenedicarboximidoyl); *N-(2,3-naphthalenedicarboximidoyl); *N-(l,8-naphthalenedicarboximidoyl); *N-indoloyl; *N-(2-pyrrolodinonyl); *N-succinimidoyl; *N-ma_eimidoyl; *3-hydantoinyl; *l,2,4-urazolyl; *amido; *urethane; *urea; and *nonaromatic substituted or unsubstituted heterocycles containing and connected through a N atom, and comprising one or two additional N, O, S, SO, or Sθ2, and containing zero, one or two carbonyls, and optionally bearing a fused benzene or pyridine ring; and *amino; *and corresponding heteroaryl moieties in which the aryl portion of an aryl-containing R? group comprises 4 - 9 carbons and at least one N, O, or S heteroatom; and *-(CH2)vZR in which v is 0 or an integer of 1 - 4, Z represents R8 is selected from the group consisting of: *alkyl; *aryl; *heteroaryl; *arylalkyl; *heteroaryl-alkyl; and *-C(0)R in which R 9 represents alkyl of at least two carbons, aryl, heteroaryl, arylalkyl, or heteroaryl-alkyl; and with the further provisos that - when R8 is -C(0)R 9 , Z is S or O; - when Z is O, R° may also be alkyleneoxy or polyalkyleneoxy terminated with H, alkyl, or phenyl; and *trialkylsilyl-substituted alkyl.

In most related reference compounds of the prior art, the biphenyl portion of the molecule is unsubstituted, and the propanoic or butanoic acid portion is either unsubstituted or has a single methyl or phenyl group. Presence of the larger phenyl group has been reported to cause prior art compounds to be inactive as anti-inflammatory analgesic agents. See, for example, R.G. Child, et al., J. Pharm. Sci., 66, 466-476 (1977) By contrast, it has now been found that compounds which exhibit potent MMP inhibitory activity contain a substituent of significant size on the propanoic or butanoic portion of the molecule. The biphenyl portions of the best MMP inhibitors also preferably contain a substituent on the 4' position, although when the propanoic or butanoic portions are optimally substituted, the unsubstituted biphenyl compounds of the invention have sufficient activity to be considered realistic drug candidates.

In another of its embodiments, the invention relates to compounds of generalized formula (I) in which the number of substituents m on the E unit is 1 or 2; and when m is 1, the group R6 constitutes a nonspiro ring; and when m is 2, both groups R^ together constitute a nonspiro ring or one group R6 is an independent substituent and the other constitutes a nonspiro ring. This subset therefore contains compounds in which the E unit carries one or two substituents R6, and at least one of these substituents is involved in a nonspiro ring. More particularly, representative compounds of generalized formula (I) in which one or more of the substituent groups R^ are involved in formation of nonspiro rings have E units of the following structures: in which a is 0, 1, or 2; b is 0 or 1; c is 0 or 1; d is 0 or 1; c + d is 0 or 1; e is 1 - 5; f is 1 - 4; g is 3 - 5; h is 2 - 4; i is 0 - 4; j is 0 - 3; k is 0 - 2; the total number of groups R 6 is 0, 1, or 2; U represents O, S, or NRl; and z is 1 or 2; Each group Rl 4 is independently selected from the group consisting of: alkyl of 1 - 9 carbons; arylalkyl in which the alkyl portion contains 1 - 7 carbons and the aryl portion contains 6 - 10 carbons; alkenyl of 2 - 9 carbons; aryl-substituted alkenyl in which the alkenyl portion contains 2 - 4 carbons and the aryl portion contains 6 - 10 carbons; alkynyl of 2 - 9 carbons; aryl-substituted alkynyl in which the alkynyl portion contains 2 - 4 carbons and the aryl portion contains 6 - 10 carbons; aryl of 6 - 10 carbons; -COR 2 ; -CH(OH)R 2 ; -CO2R 3 ; -CON(R 2 )2; -(CH2) t R 7 in which t is 0 or an integer of 1 - 4; and -(CH2)vZR 8 in which v is 0 or an integer of 1 to 3, and Z represents -S-, S(O), SO2 , or -0-.

General Preparative Methods: The compounds of the invention may be prepared by use of known chemical reactions and procedures. Nevertheless, the following general preparative methods are presented to aid the reader in synthesizing the inhibitors, with more detailed particular examples being presented below in the experimental section describing the working examples. General methods A through K may be used to prepare appropriately substituted 4-biaryl-4- oxobutanoic acids, 4-aryl-4-oxobutanoic acids, 5-biaryl-5-oxopentanoic acids, or 5- aryl-5-oxopentanoic acids to be used as key intermediates for the preparation of the compounds of the invention. These general methods are also found in WO 9615096 (23 May, 1996) along with exemplary preparations of the keto acids which are the key intermediates used for preparation of the compounds of the present application. Any one of general methods L through P may then be used to prepare the compounds of this invention from the products of methods A through K. The choice of a specific synthetic method is dictated by the proviso that the conditions used do not effect undesired changes in the T or R6 moieties of the compounds prepared. All variable groups of these methods are as described in the generic description if they are not specifically defined below. The variable subscript n is independently defined for each method. When a variable group with a given symbol (i.e. R^ or T) is used more than once in a given structure, it is to be understood that each of these groups may be independently varied within the range of definitions for that symbol. As defined above, the compounds of the invention contain as the E unit a chain of 2 or 3 carbon atoms bearing 1 to 3 substituents R^ which are not defined as H. By contrast, it is to be noted that in the general method schemes below, the R6 groups are used as if their definition includes H, to show where such Rβ groups may exist in the structures, and for ease in drawing. No change in the definition of Rβ is intended by this non- standard usage, however. Thus, only for purposes of the general method schemes below, β may be H in addition to the moieties set forth in the definition of R . The ultimate compounds contain 1 to 3 non-hydrogen groups Rβ. General Method A - The key intermediates in which the rings A and B are substituted phenyl and phenylene respectively are conveniently prepared by use of a Friedel-Crafts reaction of a substituted biphenyl II with an activated acyl- containing intermediate such as the succinic or glutaric anhydride derivative HI or acid chloride IV in the presence of a Lewis acid catalyst such as aluminum trichloride in an aprotic solvent such as 1,1,2,2-tetrachloroethane. The well known Friedel-Crafts reaction can be carried out with many alternative solvents and acid catalysts as described by E. Berliner, Org. React., 5, 229 (1949) and H. Heaney, Comp. Org. Synth., 2, 733 (1991). I-A-4 If the anhydride in is monosubstituted or multiply-substituted in an unsymmetrical way, the raw product I-A often exists as a mixture of isomers via attack of the anhydride from either of the two carbonyls. The resultant isomers can be separated into pure forms by crystallization or chromatography using standard methods known to those skilled in the art. When they are not commercially available, the succinic anhydrides HI can be prepared via a Stobbe Condensation of a dialkyl succinate with an aldehyde or ketone (resulting in side chain R"), followed by catalytic hydrogenation, hydrolysis of a hemiester intermediate to a diadd and then co version to the anhydride III by reaction with acetyl chloride or acetic anhydride. Alternatively, the hemiester intermediate is converted by treatment with thionyl chloride or oxalyl chloride to the acid chloride IV in which Rl 2 is lower alkyl. For a review of the Stobbe condensation, including lists of suitable solvents and bases see W.S. Johnson and G.H. Daub, Org. React., 6, 1 (1951). This method, as applied to the preparation of HI (Rβ = H, isobutyl and H, n-pentyl), has been described by D. Wolanin, et al., US Patent 4,771,038, Sep. 13, 1988. Method A is especially useful for the preparation of cyclic key intermediates such as I-A-3 in which two Rβ groups are connected in a methylene chain to form a 4-7 membered ring. Small ring (3-5 member) anhydrides are readily available only as cis isomers which yield cis invention compounds I-A-3. The trans compounds I-A-4 are then prepared by treatment of I-A-3 with a base such as DBU in THF. The substituted four member ring starting material anhydrides such as 1H- A-1 are formed in a photochemical 2+2 reaction as shown below. This method is especially useful for the preparation of compounds in which R i4 is acetoxy or acetoxy methylene. After the subsequent Friedel-Crafts reaction the acetate can be removed by basic hydrolysis and the carboxyl protected by conversion to 2- (trimethylsilyl)ethyl ester. The resultant intermediate with R i4 = CH2OH can be converted to key intermediates with other Rl groups by using procedures described in General Method K. The Friedel Crafts method is also useful when double bonds are found either between C-2 and C-3 of a succinoyl chain (from maleic anhydride or 1- cyclopentene-l,2-dicarboxylic anhydride, for example) or when a double bond is found in a side chain, such as in the use of itaconic anhydride as starting material to yield products in which two R^ groups as found on one chain carbon together form an exo-methylene (=CH2) group. Subsequent uses of these compounds are described in Methods D and E. General Method B - Alternatively key intermediates can be prepared via a reaction sequence involving mono-alkylation of a dialkyl malonate VI with an alkyl halide to form intermediate VII, followed by alkylation with a halomethyl biphenyl ketone VHI to yield intermediate IX. Compounds of structure IX are then hydrolyzed with aqueous base and then heated to decarboxylate the malonic acid intermediate and yield I-B-2 (Method B-l). By using one equivalent of aqueous base the esters I-B-2 with R as alkyl are obtained, and using more than two equivalents of base the acid compounds (Rl 2 = H) are obtained. Optionally, heat is not used and the diadd or acid-ester I-B-l is obtained. Alternatively, the diester intermediate IX can be heated with a strong add such as concentrated hydrochloric add in acetic add in a sealed tube at about 110 °C for about 24 hr to yield I-B-2 (R i2 = H). Alternatively, the reaction of VI with Vϋl can be conducted before that with the alkyl halide to yield the same IX (Method B-2). Intermediates Viπ are formed from biphenyls II in a Friedel-Craft reaction with haloacetyl halides such as bromoacetyl bromide or chloroacetyl chloride. Alternatively, the biphenyl can be reacted with acetyl chloride or acetic anhydride and the resultant product halogenated with, for example, bromine to yield intermediates VHI (X = Br). Method B has the advantage of yielding single regio isomers when Method A yields mixtures. Method B is especially useful when the side chains Rβ contain aromatic or heteroaromatic rings that may participate in intramolecular acylation reactions to give side products if Method A were to be used. This method is also very useful when the R" group adjacent to the carboxyl of the final compound contains heteroatoms such as oxygen, sulfur, or nitrogen, or more complex functions such as imide rings. Method B I-B-l I-B-2 General Method C - Especially useful is the use of chiral HPLC to separate the enantiomers of racemic key intermediate mixtures (see, for example, D. Arlt, B. Boemer, R Grosser and W. Lange, Angew. Chem. Int. Ed. Engl. 30 (1991) No. 12). The key intermediates are prepared as pure enantiomers by use of a chiral auxiliary route - see, for example: DA. Evans, Aldric-himica Acta, 15(2), 23 (1982) and other similar references known to one skilled in the art. C-l. Acid halide X is reacted with the lithium salt of chiral auxiliary XI (R is often isopropyl or benzyl) to yield intermediate XII, which in turn is alkylated at low temperatures (typically under -50°C) with halo-tert-butylacetyl compound XHI to yield pure isomer XIV. The use of opposite chirality XI yields opposite chirality XIV. Conversion of XIV to the enantiomerically pure diadd XV is accomplished by treatment with lithium hydroxide/hydrogen peroxide in THF/water, followed by acids such as trifluoroacetic acid. The compound XV is then converted to enantiomerically pure anhydride III-A by treatment with acetyl chloride. The use of a Friedel-Crafts reaction as in method A then converts DI-A to I-C-l. C-2. Biphenyl starting material II may also first be reacted in a Friedel- Crafts reaction as earlier described with sucdnic anhydride followed by Fisher esterification with a lower alcohol such as methanol in the presence of a strong acid such as sulfuric acid to form acyl derivative I-C-2. The carbonyl group of this material is then blocked as a ketal such as that formed by treatment with 1,2- bistrimethyl-silyloxyethane in the presence of a catalyst such as trimethyl- silyltriflate in a suitable solvent. Many other ketal derivatives and reaction conditions familiar to those skilled in the art can also be used in this step. Basic hydrolysis of the ester followed by reaction of the resultant I-C-3 with XI in the presence of an amide coupling agent such as l-(3-dimethylaminopropyl)-3- ethylcarbodiimide yields amide I-C-4. Reaction of this chiral amide with an alkylating agent such as alkyl or arylalkyl triflate or halide yields enantiomerically enriched product I-C-5 which can be converted to ketal add I-C-6 by treatment with a weak base such as lithium hydroxide /hydrogen peroxide and then to keto acid I-C-7 by treatment with an acid. These deblocking steps can be conducted in either order. Method C-1 I-C-7 General Method D - Key intermediates in which R^ are alkyl- or aryl- or heteroaryl- or acyl- or heteroarylcarbonyl-thiomethylene are prepared by methods analogous to those described in the patent publication WO 90/05719. Thus substituted itaconic anhydride XVI (n = 1) is reacted under Friedel-Crafts conditions to yield acid I-D-l which can be separated by chromatography or crystallization from small amounts of isomeric I-D-5. Alternatively, I-D-5 are obtained by reaction of key intermediates I-D-4 (from any of Methods A through C) with formaldehyde in the presence of a base. Compounds I-D-l or I-D-5 are then reacted with a mercapto derivative XVII or XViπ in the presence of a catalyst such as Potassium carbonate, ethyldiisobutylamine, tetrabutylammonium fluoride or free radical initiators such as azobisisobutyronitrile (AIBN) in a solvent such as dimethylformamide or tetrahydrofuran to yield key intermediates I-D-2, 1-D-3, 1-D-6 or I-D-7. Method D I-D-4 I-D-5 General Method E - Reaction of optionally substituted maleic anhydride XIX under Friedel-Crafts conditions with II yields key intermediate I-E-1, which in turn is reacted with either of mercapto derivatives XVII or XVHI to yield key intermediates I-E-2 or I-E-3, or with substituted amine XX to yield key intermediate I-E-4. Esterification of I-E-1 (R6 = H) with CH3I/DBU followed by reagent XXI and AgF and then basic hydrolysis yields pyrrolidine key intermediate I-E-5. Rl can be various alkyl or arylalkyl groups including benzyl. Reaction of the intermediate ester (from step 2) with benzyloxycarbonyl chloride in THF at reflux followed by hydrolysis yields key intermediates in which Rl 4 is benzyloxycarbonyl. Method E General Method F - Biaryl key intermediates such as those of this application may also be prepared by Suzuki or Stille cross-coupling reactions of aryl or heteroaryl metallic compounds in which the metal is zinc, tin, magnesium, lithium, boron, silicon, copper, cadmium or the like with an aryl or heteroaryl halide or triflate (trifluoromethane-sulfonate) or the like. In the equation below either Met or X is the metal and the other is the halide or triflate. Pd(com) is a soluble complex of palladium such as tetrakis(triphenylphosphine)-palladium(0) or bis-(triphenylphos-phine)-palladium(π) chloride. These methods are * " well known to those skilled in the art. See, for example, A. Suzuki, Pure Appl. Chem., 66, 213 - 222 (1994); A. Suzuki, Pure Appl. Chem., 63, 419 - 422 (1991); and V. Farina and G. Roth, "Metal-Organic Chemistry" Volume 5 (Chapter 1), 1994. The starting materials XXIII (B = 1,4-phenylene) are readily formed using methods analogous to those of methods A, B or C but using a halobenzene rather than a biphenyl as starting material. When desired, the materials in which X is halo can be converted to those in which X is metal by reactions well known to those skilled in the art such as treatment of a bromo intermediate with hexamethylditin and palladium tetrakistriphenylphosphine in toluene at reflux to yield the trimethyltin intermediate. The starting materials XXIII (B = heteroaryl) are most conveniently prepared by method C but using readily available heteroaryl rather than biphenyl starting materials. The intermediates XXII are either commercial or easily prepared from commercial materials by methods well known to those skilled in the art. These general methods are useful for the preparation of key intermediates for which Friedel-Crafts reactions such as those of Methods A, B, C, D or E would lead to mixtures with various biaryl acylation patterns. Method F is also especially useful for the preparation of key intermediates in which the aryl groups A or B contain one or more heteroatoms (heteroaryls) such as those compounds that contain thiophene, furan, pyridine, pyrrole, oxazole, thiazole, pyrimidine or pyrazine rings or the like instead of phenyls. Method F (T) X A-Met + X-B-E-G (T) X A-B-D-E-G Pd(com) xxπ xxm I-F T, x, A, B, E and G as in Structure I Met = Metal and X = Halide or Triflate or Met = Halide or Triflate and X = Metal General Method G - When the Rβ groups of method F form together a 4 - 7 member carbocyclic ring as in Intermediate XXV below, the double bond can be moved out of conjugation with the ketone group by treatment with two equivalents of a strong base such as lithium diisopropylamide or lithium hexamethylsilylamide or the like followed by acid quench to yield compounds with the structure XXVI. Reaction of XXVI with mercapto derivatives using methods analogous to those of General Method D then leads to key intermediate I-G-l or I-G-2. Method G General Method H - Key intermediates in which two R > groups form a 4 - 7 member carbocyclic ring as in I-H below and R i is alkyl or arylalkyl are prepared according to method H. Starting material XXVH is reacted with two equivalents of a strong base such as lithium diisopropylamide (LDA) followed by an alkyl or arylalkyl halide (R i4 X) to yield intermediate XXVHI. This material is then reduced to the alcohol with a reducing agent capable of selective reduction of the ketone such as sodium borohydride, followed by dehydration with triphenylphosphine / diethyl azodicarboxylate (DEAD) in a suitable solvent such as TP-F at reflux to yield XXIX. Hydrolysis of the ester with aqueous base followed by amide formation with R 20NHR12 (R is lower alkyl, but usually CH3) in the presence of a coupling agent such as dicyclohexyldiimide (DCC) yields XXX. . Other acyl activating groups well known to those skilled in the art such as add chlorides or mixed anhydrides could be used instead of XXX. Substituted biphenyl halide XXXI is reacted with an alkyl lithium such as two equivalents of t-butyl lithium to yield lithiated biphenyl XXXII which is then reacted with activated acyl compound XXX. The resultant intermediate XXXIII is then treated with diethylaluminum cyanide to yield intermediate XXXIV which is then hydrolyzed with aqueous add to yield key intermediate I-H which is purified by chromatography on silica gel to afford pure isomers. Method H 1) Reduction 2) Dehydration XXX Coupling agent xxrx I-H General Method I - Key intermediates in which two R6 groups together form a pyrrolidine ring are prepared according to method I. Starting material XXXV (L-pyroglutaminol) is reacted under add catalysis with benzaldehyde XXXVI (may be substituted) to yield bicyclic derivative XXXVII. A double bond is then introduced using phenylselenenyl methodology well known to those skilled in the art to yield XXXVI , which, in turn, is reacted with a vinylcopper (I) complex to yield conjugate addition product XXXIX. Such reactions in which Lig can be, for example, another equivalent of vinyl group or halide are well known to those skilled in the art. Hydride reduction (lithium aluminum hydride or the like) of XXXIX followed by standard blocking with, for example, t-butyldimethylsilylchloride yields XXXX which in turn is reacted with an optionally substituted benzylchloroformate XXXXI to yield XXXXII. Ozonolysis of this intermediate followed by reductive workup (dimethylsulfide, zinc/acetic add or the like) leads to aldehyde XXXXI . Reaction of this aldehyde with a biphenyl organometallic such as XXXII yields alcohol XXXXTV. Deblocking of the silyl group with, for example, tetrabutylammonium fluoride followed by oxidation with, for example, pyridiniumdichromate or the like yields key intermediate 1-1-1 in which Rl 4 is a carbobenzyloxy group. Alternatively the carbobenzyloxy group is removed by reaction with hydrogen and a catalyst such as palladium on carbon to yield the unsubstituted key intermediate 1-1-2 optionally followed by N-alkylation to yield key intermediate 1-1-3. These final steps are well known to those skilled in the art. Alternatively the intermediate XXXX can be directly treated with ozone followed by the other steps of this method to yield 1-1-3 in which Rl 4 is optionally substituted benzyl rather than as in 1-1-1. This method is especially useful to prepare single enantiomers because starting material XXXV is available as either the isomer as drawn or as D- pyroglutaminol to yield enantiomeric products. Method I General Method J - The key intermediates in which E represents a substituted chain of 3 carbons are prepared by method J. Intermediates XXXXVQ, if not available from commercial sources, are prepared by reaction of an activated biphenylcarboxylic add derivative XXXXV with substituted acetic acid XXXXVI which has been converted to its bis anion with two equivalents of a strong base such as LDA followed by heating to decarboxylate the intermediate keto acid. Product XXXXVII is then treated with methylenemalonate derivative XXXXVπi in the presence of a strong base such as sodium hydride to yield substituted malonate XXXXIX. This malonate can be further alkylated under conditions familiar to those skilled in the art to yield L which in turn is treated with acid and then heated to yield key intermediate 1-J-l. Alternatively the final alkylation can be omitted to yield products in which the R^ adjacent to the carboxyl is H. Alternatively XXXXVII can be alkylated with 3-halopropionate ester LI in the presence of base such as LDA to yield ester l-J-2 which can then be hydrolyzed with aqueous base to yield key intermediate l-J-3 upon treatment with add. This method is espedally useful if any of the groups R^ contain aromatic residues. Method J Method K - The key intermediates in which two R6 groups are joined to form a substituted 5-member ring are most conveniently prepared by method K. In this method add LU (R = H) is prepared using the protocols described in Tetrahedron, Vol. 37, Suppl., 1981, 411. The acid is protected as an ester (R = benzyl or 2-(trimethylsilyl)ethyl) by use of coupling agents such as l-(3- dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride and procedures well known to those skilled in the art. Substituted bromobiphenyl LIU is converted to its Grignard reagent by treatment with magnesium which is then reacted with IH to yield alcohol LIV. Alcohol LIV is eliminated via base treatment of its mesylate by using conditions well known to those skilled in the art to yield olefin LV. Alternatively LIE is converted to a trimethyltin intermediate via initial metallation of the bromide with n-butyllithium at low temperature (-78°) followed by treatment with chlorotrimethyltin and LU is converted to an enoltriflate by reaction with 2-[N,N-bis(trifluoromethylsulfonyl)amino]-5-chloropyridine in the presence of a strong aprotic base. The tin and enoltriflate intermediates are then coupled in the presence of a Pd° catalyst, Cul and AsPh3 to yield directly intermediate LV. Ozonolysis of LV (workup with methyl sulfide) yields aldehyde LVL Alternatively treatment with Osθ4 followed by HIO4 converts LV to LVL Conversion of intermediate LVI to key intermediate I-K is accomplished in several ways depending on the identity of side chain function X. Reaction of LVI with Wittig reagents followed by hydrogenation yields products in which X is alkyl, aryl or arylalkyl. Reduction of aldehyde LVI with LAH yields alcohol I-K (X = OH). The alcohol is converted to phenyl ethers or N-phthalimidoyl compounds by use of the appropriate starting materials and Mitsunobu conditions well known to those skilled in the art; see O Mitsunobu, Synthesis, 1 (1981). Alternatively the alcohol of I-K (X = OH) is converted to a leaving group such as tosylate (X = OTs) or bromide (X = Br) by conditions well known to those skilled in the art and then the leaving group is displaced by sulfur or azide nucleophiles to yield products with X = thioether or azide which in turn is reduced and acylated to yield amides (X = NHAcyl). Direct acylation of the alcohol I-K (X = OH) yields key intermediates in which X = OAcyl and reaction of the alcohol with various alkyl halides in the presence of base yields alkyl ethers (X = OR^). In each case a final step is removal of add blocking group R to yield adds (R = H) by using conditions which depend on the stability of R and X, but in all cases well known to those skilled in the art such as removal of benzyl by base hydrolysis or of 2-(trimethylsilyl)ethyl by treatment with tetrabutylainmonium fluoride. Method K LV Ozone then methylsulfide Method L - The 4-oxobutanoic or 5-oxopentanoic adds LVH which have been prepared by one of methods A through K are reduced to hydroxyacids LVDI by the action of a selective hydride reducing agent such as sodium borohydride, sodium triacetoxyborohydride, or sodium cyanoborohydride in a suitable solvent such as water, ethanol or tetrahydrofuran at 0°C to ambient temperature. Alternatively, the reducing agent can be any number of other reagents used by one skilled in the art to reduce a carbonyl to a secondary alcohol, with the proviso that such reducing agent does not effect undesired changes in the T, carboxy, or R6 moieties of the oxoacids. The isomers of the product can be isolated in pure form by a combination of crystallization and chromatography. Hydroxyacid LVDI is converted to lactone LIX by reaction with a catalytic amount of add such as toluenesulfonic add or camphorsulfonic acid in a suitable solvent such as benzene, toluene or methylene chloride at between 0 °C and reflux. Reaction of lactone LIX with hydroxylamine derivation NH2ORH in a suitable solvent such as ethanol, methanol, THF, toluene, or methylene chloride in the presence of a suitable catalyst such as sodium hydroxide, sodium methoxide, triethylamine, N-ethylmorpholine, trimethylaluminum, or dimethylaluminum chloride leads to intermediate LX. RU may be H, in which case LX is an invention compound, or RU may be a blocking group such as benzyl, trimethylsilyl, or tert- butyldimethylsilyl. If RU is a blocking group, then it is removed by a suitable reaction such as hydrogenation or transfer hydrogenation when RU is benzyl or treatment with (n-Bu)4NF or acid when RU is trialkylsilyl to yield invention compound I-L. The choice of catalyst and blocking group RU is dictated by the proviso that the conditions used do not effect undesired changes in the T or R6 moieties of the invention compounds. For example, when Rβ contains a phthalimide moiety which is sensitive to base, add conditions are chosen by one skilled in the art. Method L Acid LX LIX Deblocking Method M - Alternatively, the 4- or 5-hydroxyhydroxamic acids may be prepared as shown in Method M. The hydroxy acid LVDI is converted to the O- tert-butyldimethylsilyloxy acid LXII as shown according to the methods described by D.J. Abraham, et al, J. Med. Chem., 27, 1549-1559 (1984). Intermediate LXH can be converted to the activated ester LXH in which X is, for example, z ' so- butoxycarbonyloxy by reaction with isobutyl chloroformate in an a suitable solvent in the presence of a suitable tertiary amine base such as triethylamine. Reaction of intermediate LXHI with a hydroxylamine derivative such as O-tert- butyldimethylsilyl hydroxylamine yields intermediate LXIV. Alternatively, LXE may be converted directly to LXT by treatment with a mixture of O-tert- butyldimethylsilyl hydroxylamine and a suitable coupling agent such as l-(3- dimethylaminopropyl)-3-ethylcarbodiimide methiodide in a suitable solvent such as THF or methylene chloride. Intermediate LXIV is then converted to invention compound I-L by treatment with reagents such as acetic add / water mixtures, aqueous mineral add or (n-butyl)4NF. The choice of deblocking conditions is dictated by the proviso that the conditions used do not effect undesired changes in the T or R^ moieties of the invention compounds.

Thus the active acyl intermediate LXIII is reacted with diazomethane to yield diazomethylketone LXIV which in turn is treated with aqueous sulfuric acid to both convert the diazo group to a hydroxyl and remove the TBDMS group to yield invention compound I-N. Alternatively, T.XTTT can be treated with l,l,2-_rzs-(tr_methylsilyloxy)ethylene in the presence of SnCLj, followed by aqueous acid to yield I-N. Method N CiTBDMS CH TBDMS CDχA-B- -E-C(0)X 2 —?~ (T) X A— B- E-C(0)CH 2 N 2 H H I-N Method O - Invention compounds in which D is a carbonyl are most conveniently prepared as shown in Method O. Intermediate I-C-6 from Method C-2 is first converted to the active acyl compound LXV by methods well known to those skilled in the art. Intermediate LXV may be an add halide or mixed anhydride. Reaction of LXV with diazomethane yields diazomethyl ketone LXVI which, in turn, is converted to invention compound I-O-l by treatment with aqueous sulfuric add. Intermediate LXV may also be converted to hydroxamic add derivative LXVπ by treatment with hydroxylamine derivative NH2ORH, in which RH may be H, tert-bxx yl or trialkylsilyl. Intermediate LXVII is then converted to invention compound 1-0-2 by treatment with aqueous add. Condensation of I-O-l with one equivalent of NH2Y^ in a suitable solvent in the presence of a suitable catalyst well known to those skilled in the art yields a mixture of oximes, oxime ethers or hydrazones from which invention compound I-0-3 can be isolated by chromatography. In this step, Y^ is defined as OR^ or N(R2)2 in which the R^ groups can be the same or different. Condensation of I-O- 2 with NH2Y in a similar way leads to invention compound 1-0-4. Method O I-O-l 1-0-2 1-0-3 1-0-4 Method P - Invention compounds with an acylsulfonamide as carboxy isostere are prepared according to Method P. Intermediate LVII is first activated by conversion to an add halide or preferentially to a mixed anhydride using methods well known to those skilled in the art and then the activated intermediate is reacted with NH2S(0)2R^ to yield invention compound I-P-l. Alternatively, a coupling agent such as l,l'-carbonyldiimidazole and a base such as DBU can be used together with NH2S(0)2 3 to effect this transformation Reduction of the keto moiety of I-P-l is conducted by use of a mild reducing agent such as sodium borohydride in a suitable solvent such as ethanol to yield invention compound I-P- 2. Alternatively, Intermediate LXIII is reacted with NH2S(0)2R^ in the presence of a suitable base and the resultant intermediate is treated with add or tetrabutylammonium fluoride to yield invention compound I-P-2. Condensation of I-P-l with NH2Y yields invention compound I-P-3. I-P-2 Suitable pharmaceutically acceptable salts of the compounds of the present invention that contain an acidic moiety include addition salts formed with organic or inorganic bases. The salt forming ion derived from such bases can be metal ions, e.g., aluminum, alkali metal ions, such as sodium of potassium, alkaline earth metal ions such as calcium or magnesium, or an amine salt ion, of which a number are known for this purpose. Examples include ammonium salts, arylalkylamines such as dibenzylamine and N,N-dibenzylethylenediamine, lower alkylamines such as methylamine, t-butylamine, procaine, lower alkylpiperidines such as N-ethylpiperidine, cycloalkylamines such as cyclohexylamine or dicyclohexylamine, 1-adamantylamine, benzathine, or salts derived from amino acids like arginine, lysine or the like. The physiologically acceptable salts such as the sodium or potassium salts and the amino acid salts can be used medicinally as described below and are preferred. Suitable pharmaceutically acceptable salts of the compounds of the present invention that contain a basic moiety include addition salts formed with organic or inorganic acids. The salt forming ion derived from such acids can be halide ions or ions of natural or unnatural carboxylic or sulfonic acids, of which a number are known for this purpose. Examples include chlorides, acetates, tartrates, or salts derived from amino acids like glycine or the like. The physiologically acceptable salts such as the chloride salts and the amino acid salts can be used medicinally as described below and are preferred. These and other salts which are not necessarily physiologically acceptable are useful in isolating or purifying a product acceptable for the purposes described below. For example, the use of commercially available enantiomerically pure amines such as (+)-cinchonine or either isomer of α-methylbenzyl amine or pure acids such as either isomer of tartaric add in suitable solvents can yield salt crystals of a single enantiomer of the invention compounds, leaving the opposite enantiomer in solution in a process often referred to as "classical resolution." As one enantiomer of a given invention ' compound is usually substantially greater in physiological effect than its antipode, this active isomer can thus be found purified in either the crystals or the liquid phase. The salts are produced by reacting the acid form of the invention compound with an equivalent of the base supplying the desired basic ion or the basic form of the invention compound with an equivalent of the acid supplying the desired acid ion in a medium in which the salt precipitates or in aqueous medium and then lyophilizing. The free acid or basic form of the invention compounds can be obtained from the salt by conventional neutralization techniques, e.g., with potassium bisulfate, hydrochloric acid, sodium hydroxide, sodium bicarbonate, etc. The compounds of the present invention are expected to inhibit the matrix metalloproteases MMP-1, MMP-2, MMP-3, MMP-8, MMP-9, MMP-12, MMP-13, and the related protease TACE, as well as the release of TNFα in vivo, and are therefore expected to be useful for treating or preventing the conditions referred to in the background section. As other MMPs not listed above share a high degree of homology with those listed above, especially in the catalytic site, it is deemed that compounds of the invention should also inhibit such other MMPs to varying degrees. Varying the substituents on the biaryl portions of the molecules, as well as those of the R6 groups of the claimed compounds, is expected to affect the relative inhibition of the listed MMPs. Thus compounds of this general class can be "tuned" by selecting specific substituents such that inhibition of specific MMP(s) associated with specific pathological conditions can be enhanced while leaving non-involved MMPs less affected. The method of treating matrix metalloprotease-mediated or TNFα release- mediated conditions may be practiced in mammals, including humans, which exhibit such conditions. The inhibitors of the present invention are contemplated for use in veterinary and human applications. For such purposes, they will be employed in pharmaceutical compositions containing active ingredient(s) plus one or more pharmaceutically acceptable carriers, diluents, fillers, binders, and other excipients, depending on the administration mode and dosage form contemplated. Administration of the inhibitors may be by any suitable mode known to those skilled in the art. Examples of suitable parenteral administration indude intravenous, intraarticular, subcutaneous and intramuscular routes. Intravenous administration can be used to obtain acute regulation of peak plasma concentrations of the drug. Improved half-life and targeting of the drug to the joint cavities may be aided by entrapment of the drug in liposomes. It may be possible to improve the selectivity of liposomal targeting to the joint cavities by incorporation of ligands into the outside of the liposomes that bind to synovial- specific macromolecules. Alternatively intramuscular, intraarticular or subcutaneous depot injection with or without encapsulation of the drug into degradable microspheres e.g., comprising poly(DL-lactide-co-glycolide) may be used to obtain prolonged sustained drug release. For improved convenience of the dosage form it may be possible to use an i.p. implanted reservoir and septum such as the Percuseal system available from Pharmacia. Improved convenience and patient compliance may also be achieved by the use of either injector pens (e.g. the Novo Pin or Q-pen) or needle-free jet injectors (e.g. from Bioject, Mediject or Becton Dickinson). Prolonged zero-order or other precisely controlled release such as pulsatile release can also be achieved as needed using implantable pumps with delivery of the drug through a cannula into the synovial spaces. Examples include the subcutaneously implanted osmotic pumps available from ALZA, such as the ALZET osmotic pump. Nasal delivery may be achieved by incorporation of the drug into bioadhesive particulate carriers (<200 μm) such as those comprising cellulose, polyacrylate or polycarbophil, in conjunction with suitable absorption enhancers such as phospholipids or acylcarnitines. Available systems include those developed by DanBiosys and Scios Nova. Oral delivery may be achieved by incorporation of the drug into tablets, coated tablets, dragees, hard and soft gelatine capsules, solutions, emulsions or suspensions. Oral delivery may also be achieved by incorporation of the drug into enteric coated capsules designed to release the drug into the colon where digestive protease activity is low. Examples include the OROS-CT/Osmet™ and PULSINCAP™ systems from ALZA and Scherer Drug Delivery Systems respectively. Other systems use azo-crosslinked polymers that are degraded by colon specific bacterial azoreductases, or pH sensitive polyacrylate polymers that are activated by the rise in pH at the colon. The above systems may be used in conjunction with a wide range of available absorption enhancers. Rectal delivery may be achieved by incorporation of the drug into suppositories. The compounds of this invention can be manufactured into the above listed formulations by the addition of various therapeutically inert, inorganic or organic carriers well known to those skilled in the art. Examples of these indude, but are not limited to, lactose, corn starch or derivatives thereof, talc, vegetable oils, waxes, fats, polyols such as polyethylene glycol, water, saccharose, alcohols, glycerin and the like. Various preservatives, emulsifiers, dispersants, flavorants, wetting agents, antioxidants, sweeteners, colorants, stabilizers, salts, buffers and the like are also added, as required to assist in the stabilization of the formulation or to assist in increasing bioavailability of the active ingredient(s) or to yield a formulation of acceptable flavor or odor in the case of oral dosing. The amount of the pharmaceutical composition to be employed will depend on the recipient and the condition being treated. The requisite amount may be determined without undue experimentation by protocols known to those skilled in the art. Alternatively, the requisite amount may be calculated, based on a determination of the amount of target enzyme which must be inhibited in order to treat the condition. It is expected that the compounds of the invention generally will be administered in doses in the range of 0.01-100 mg per kg of body weight per day. The matrix metalloprotease inhibitors of the invention are useful not only for treatment of the physiological conditions discussed above, but are also useful in such activities as purification of metalloproteases and testing for matrix metalloprotease activity. Such activity testing can be both in vitro using natural or synthetic enzyme preparations or in vivo using, for example, animal models in which abnormal destructive enzyme levels are found spontaneously (use of genetically mutated or trans genie animals) or are induced by administration of exogenous agents or by surgery which disrupts joint stability. Experimental: General Procedures: All reactions were performed in flame-dried or oven-dried glassware under a positive pressure of argon and were stirred magnetically unless otherwise indicated. Sensitive liquids and solutions were transferred via syringe or cannula and were introduced into reaction vessels through rubber septa.

Example 1 Compounds A and B Step 1 4-[4-(4-Chlorophenyl)phenyl]-4-oxo-2-isobutylbutanoic add was prepared as described in WO-09615096 (Example 1). A portion of this material (103.5 mg, 0.300 mmol) was dissolved in 20 ml of water with the addition of 30.0 mg (0.687 mmol) of sodium hydroxide. The solution was cooled in an ice bath and then 13.0 mg (0.344 mmoles) of sodium borohydride was added as a solid. Stirring continued for 1 h. TLC (methylene chloride-2.5% methanol) indicated that starting material was still present, so the reaction was allowed to warm to room temperature overnight (16.5 h). Starting material was still present, so 13.0 mg more sodium borohydride was added at room temperature. The reaction was stirred for 2 h and then quenched with 10% HC1 and extracted twice with ethyl acetate. The combined organic extracts were washed once with brine and dried over MgSθ4. The solution was concentrated in vacuo to give 57.0 mg of a crude solid. This was purified by silica gel chromatography (methylene chloride- methanol) to give two major 4-hydroxybutyric acid products A (7.9 mg) and B (19.1 mg). Compound A: IH NMR (MeOD-d3) 57.56 (m, 4H), 7.38 (m, 4H), 4.66 (dd, J=9 Hz, J=3 Hz, IH), 2.77 (m, 1H),1.95 (m, IH), 1.75, 1.57 (m, 3H), 1.26 (m, IH), 0.85 (d, J=6 Hz, 3H), 0.79 (d, J=6 Hz, 3H). Compound B: T-H NMR (MeOD-d3) δ 7.58 (m, 4H), 7.40 (m, 4H), 4.64 (t, J=6 Hz, IH), 2.34 (m, IH), 2.10 (m and solvent), 1.74 (m, IH), 1.54 (m, 2H), 1.28 (m, 2H), 0.87 (d, J=6 Hz, 3H), 0.77 (d, J=6 Hz, 3H). Compounds C and D Step 2 The lactones C and D were prepared by dissolving a mixture of hydroxyacids A and B (51 mg) in 25 ml benzene along with camphor sulfonic add (11 mg). This mixture was refluxed for 12 hours using a Dean-Stark trap. The resultant solution was washed with aqueous sodium bicarbonate, dried over MgSθ4 and evaporated in vacuo. The residue was purified by silica gel chromatography with Hexane-EtOAc to give the separated lactones. Lactone C: H NMR (CDCI3) δ 7.3-7.7 (m, 8H), 5.6 (m, IH), 2.75 (m, IH), 2.45 (m, 2H), 2.20 (solvent), 1.75 (m, 2H), 1.45 (m, IH), 1.01 (d, J=7 Hz, 3H), 0.87 (d, J=7 Hz, 3H); MS (FAB-LSIMS) 329 [M+H]+ (C20H21O2CI FW=328.87). Lactone D: IH NMR (CDCI3) δ (m, 8H), (m, IH), (m, IH), 2 (m, 2H), 2.20 (solvent), 1.75 (m, 2H), 1.45 (m, IH), 1.01 ( d, J=7 Hz, 3H), 0.87 (d, J=7 Hz, 3H); MS (FAB-LSIMS) 328 [M]+ (C20H21O2CI FW=328.87). Step 3 O-Benzylhydroxylamine hydrochloride (22.3 mg, 0.14 mmol) was suspended in dry acetonitrile (1 ml) with ice / salt bath cooling as a ^ solution of trimethylaluminum in toluene (0.07 ml, 2 M, 0.14 mmol) was added. After stirring for 1 hr at cold temperature, the mixture was allowed to come to room temperature for 2.5 hr. before a solution of C and D lactone mixture from step 2 (22 mg in 0.5 ml) was added. After stirring for two hours the product could be seen to form by tic analysis. Lactone mixture Rf 0.86, product isomers Rf 0.15 and 0.19 (2.5 % methanol in methylene chloride). After stirring overnight the product mixture was quenched by mixing with aqueous hydrochloric acid and extracted with ethyl acetate. The desired products along with some recovered starting materials can be isolated in pure form from the extract by chromatography. Example 1 Step 4 The benzyl blocked products of step 3 can be de-blocked by hydrogenation at between atmospheric pressure and 60 PSI hydrogen gas in methanol in the presence of 5 - 10 % palladium on carbon to yield the desired invention compound hydroxamic acids. Example 2 Step 1 The alcohol products of step 3 of example 1 can be dissolved in acetone and oxidized with chromic add (Jones reagent) at between O °C and room temperature to yield the keto compound. Example 2 Step 2 The products of step 1 can be de-blocked by hydrogenation at between atmospheric pressure and 60 PSI hydrogen gas in methanol in the presence of 5-10 % palladium on carbon to yield the desired invention compound hydroxamic adds. Example 3 Step 1 A solution of 4-oxo-4-biphenylbutyric add (500 mg) in ethyl acetate (50 ml) / methylene chloride (5 ml) was stirred with ice bath cooling as an etherial solution of diazomethane was added slowly until the yellow color of excess reagent persisted. The resultant solution was evaporated in vacuo to yield pure methyl ester (528 mg, 100%). Example 3 Step 2 A solution of hydroxylamine hydrochloride (110 mg, 1.58 mmol) in methanol (2 ml) was prepared by warming and then a second solution of potassium hydroxide (183 mg, 3.26 mmol) in water (1 ml) was added. The resultant mixture was cooled in an ice bath and stirred as the product from step 1 above (200 mg, 0.74 mmol) was added. The resultant mixture was warmed and sonicated to form a homogeneous solution before it was re-cooled and partially evaporated to remove methanol. A 10 % aqueous acetic add solution (ca. 20 ml) was added. A white precipitate of the invention compound (133 mg) formed which was collected by filtration and dried in vacuo. Example 4 A mixture of the product Example 2 (1 mmol), hydroxylamine hydrochloride (1.1 mmol), and sodium carbonate (1.1 mmol) in dry ethanol can be refluxed under argon to form the invention compound. After cooling, the product can be recovered by evaporation to remove solvents and then mixed with 10 % acetic acid and processed as in example 3 to yield purified material. Example 5 Example 5 A mixture of the product of Example 2 (1 mmol) and 1,1-dimethylhydrazine (2.2 mmol) in absolute ethanol (4 ml) can be refluxed under argon to yield the invention compound. The product solution can be evaporated in vacuo and the residue chromatographed to yield pure material. Examples 6 and 7 Compound G Compound H Step 1 [S]-4-[4-(4-Chlorophenyl)phenyl]-4-oxo-2-(phenylthiomethyl)-butanoic acid was prepared as described in WO-09615096 (Example 197). A solution of this material (6.52 g, 15.9 mmol) in absolute ethanol (100 ml) was stirred under argon with ice bath (0 °C) cooling as sodium borohydride (4.12 g, 109 mmol) was added in portions. The reaction mixture was stirred as the ice bath melted and then at ambient temperature overnight. The resultant mixture which contained significant white solid was quenched by the addition of water (100 ml) and then evaporated in vacuo to ca. 1/3 volume. The condensed mixture was mixed with ca. 100 ml of ethyl acetate and then mixed vigorously as it was cautiously quenched with IN hydrochloric add until the aqueous phase was strongly addic (evolution of hydrogen gas from excess borohydride). The aqueous phase was removed and the organic was washed several times with water, then brine and then dried over sodium sulfate and evaporated in vacuo. The residue was dissolved as much as possible in 100 ml of a methylene chloride / methanol mixture (99:1) and then filtered to remove a white solid which proved to be pure single isomer E ([2S, 4S]-4-[4-(4-chlorophenyl)phenyl]-4-hydroxy-2- (phenylthiomethyl)-butanoic acid) as shown by analytical HPLC (silica column, 1 ml/min. 99:1 methylene chloride /methanol plus 0.05% acetic acid, peak detection at 254 nM, this 4-S isomer is the second to elute). The filtrate was chromatographed on a preparative (46 mm ID) silica HPLC column using the same solvent at 80 ml/min. to yield 444 mg of pure F (4R isomer) by condensation of the best fractions in vacuo to a low volume, cooling and collection of crystals by filtration. Preparative HPLC of the combined early fractions using either 5 % ethyl acetate in hexane or a slow gradient of 0-1 % methanol in methylene chloride led to the isolation of pure samples of each of the γ-butyrolactone isomers (G and H). Determination of the relative stereochemistry around chiral ring carbons can be achieved by identifying the relative position of the protons attached to these carbons, i.e. whether pairs of protons are on the same or on the opposite side of the ring plane. NMR spectroscopy, in particular one- or two-dimensional nuclear Overhauser spectroscopy (NOESY), is the ideal technique to solve this problem, taking advantage of differential nuclear Overhauser enhancements (NOEs) based on the relative spatial proximity of protons. See Macura, S. and Ernst, R.R., /. Mol. Biol. , 1980, 206, 397. This was done for the two isomers of the γ-butyrolactone to show a greater NOE between H-1 and H-4 of the isomer with those protons ds (2S, 4S) than that of the isomer with those protons trans (2S, 4R). All other NOEs observed between the other protons on the lactone ring and attached CH 2 of the two isomers were self consistent with this interpretation. While the purified crystalline hydroxy adds (Compounds E and F) are relatively stable as solids, aged solutions of these compounds slowly showed one or other of the lactones as a result of spontaneous lactonization occurring. This was evidenced by the chemical shift of H-4 on the 4S lactone at δ 5.40 ppm and that on the 4R lactone at δ 5.65 ppm. The hydroxy add that converted to the 2S, 4R lactone was thus identified as the 2S, 4R hydroxy acid (Compound E) and that which converted to the 2S, 4S lactone was identified as the 2S, 4S hydroxy add (Compound F). Compound E (2S, 4R): MP 122-123 °C; HPLC (1 ml/min. 1% methanol... in methylene chloride plus 0.05% acetic acid, Rainin 4.6 mm x 25 cm silica column) tR = 10.02 min.; [αfo + 64.4 ° (c 0.55, acetone); *HNMR (Acetone-d 6 ) δ 7.12-7.7 (m, 13H), 4.82 (dd, J = 4.04, 8.45 Hz, IH), 3.2 (m, 2H), 2.98 (m, IH), others under acetone peak.

Compound G (2S, 4R): MP 122-123 °C; ΗNMR (CDC1 3, , 500 MHz) δ 7.21-7.60 (series of m, 13H, aromatic H), 5.65 (dd, J = 4.59, 7.98 Hz, IH, H-4), 3.55 (dd, J = 3.74, 13.29 Hz, IH, SCH), 3.04 (dd, J = 9.97, 13.28 Hz, IH, SCH), 2.94-2.98 (m, IH, H-2), 2.64-2.70 (m, IH, H-3A), 2.46-2.51 (m, IH, H-3B). Compound H (2S, 4S): MP 142-143 °C; 1 HNMR (CDC1 3 , 500 MHz) δ 7.21-7.60 (series of m, 13H, aromatic H), 5.40 (dd, J = 5.79, 10.58 Hz, IH, H-4), 3.65 (dd, J = 3.50, 13.40 Hz, IH, SCH), 2.96 (dd, J = 9.90, 13.37 Hz, IH, SCH), 3.02-3.07 (m, IH, H-2), 2.87-2.92 (m, IH, H-3A), 2.07 (dd, J = 12.26, 23.08 Hz, IH, H-3B).

Thus the product E or F from step 1 (1 mmol) can be reacted with terf-butyldimethylsilyl chloride (3 mmol) and imidazole (7.3 mmol) in dry tetrahydrofuran (3 ml) and dry DMF (1 ml) under argon at ambient temperature for about 2 days and then the solid removed by filtration and the filtrate evaporated in vacuo to yield a residue of deblocked material. This residue can be purified by chromatography on silica gel to both deblock the add function and purify the products I or J. Compound K Compound L Step 3 A dry methylene chloride solution'of the product I or J from step 2 (1 mmol), O-ter^butyldimethylsilyl hyroxylamine (1 - 4 mmol) and 1- hydroxybenzotriazole (1 mmol) can be cooled in an ice bath as l-ethyl-3-(3- dimethylaminopropyl)carbodiimide (1 - 1.5 mmol) is added. After the reaction mixture has stirred for several hours at 0 °C, it is left to stir at ambient temperature until a TLC assay indicates that the starting material I or J has been substantially consumed. The product K or L can be isolated by dilution with dilute hydrochloric acid, extraction with methylene chloride, evaporation of the extracts and chromatography and /or recrystallization of the residue.

Preparation of Gelatinase-B (MMP-9): MMP-9 is isolated modifying the previously described procedures of Hibbs et al (J. Biol. Chem., 260, 2493-2500, 1984) and Wilhelm et al (J. Biol. Chem., 264, 17213-17221, 1989). Briefly, polymorphonuclear leukocytes (PMN) preparations are isolated as described above from 3 or more units of freshly drawn whole blood. Cells are resuspended in phosphate buffered saline (PBS) containing 100 ng/ml phorbol myristate acetate (PMA) in the presence of 50 mM di- isopropylfluorophospate (DFP), 1 μg/ml leupeptin and aprotinin, and 1 mg/ml catalase for 1 hr at 37°C. Supernatants are collected by centrifugation (300 x g) and the samples are frozen at -70 C. All chromatographic methods are performed at 4°C. Thawed samples are concentrated 5-fold using an Amicon chamber equipped with a YM-10 membrane. The concentrate is pressure dialyzed against 0.02M Tris-HCl, 0.1 M NaCl, 1 mM CaC_2 , 1 μM ZnCl2, 0.001% Brij-35, 0.02% sodium azide (NaN3), pH 7.5 and applied to DEAE ion exchange chromatography resin which is previously equilibrated with the same buffer at a flow rate of 0.4 ml/min.

The protein content associated with material is determined with a micro-BCA assay (Pierce, Rockford, IL), lyophilized and reconstituted to a desired working concentration (100 μg/ml). Preparation of Gelatinase-A (MMP-2): Gelatinase A (MMP-2) is prepared using a vaccinia expression system according to the method of R. Fridman, et al., /. Biol. Chem., 267, 15398 (1992). Preparation of Recombinant Truncated Prostromelysin (MMP-3): Truncated Prostromelysin-257 is expressed in a soluble form in E.coli as described by Marcy et al., Biochemistry, 30, 6476-6483, 1991. Soluble truncated prostromelysin is purified by a modification of the monoclonal antibody affinity chromatography method described by Housley et al, J. Biol. Chem., 268, 4481-87, 1993. P218 Quenched fluorescence Assay for MMP-3 Inhibition: This assay was originally described by Knight et al, FEBS Letters, 296, 263- 266, 1992, for a related substrate. The assay is run continuously in a 3.0ml cuvette using a Perkin-Elmer LS 50 B Spectrofluorimeter at 25 °C in a final volume of 2.0mls. P218 substrate (lOmM) in 100% DMSO is diluted to a final concentration of 2.0 micromolar (μM) into assay buffer: 50mM MES, pH 6.5 containing 150mM NaCl, lOmM CaC12, 0.005% Brij-35, and l%(v/v) DMSO. Test compounds(lOmM) in DMSO are diluted in assay buffer at an initial concentration of 10 to 100 micromolar. These are diluted to a final concentration in the assay from 10 nM to 1 μM depending upon their potency previously determined in primary thiopeptilide assay described above. The reaction is initiated by the addition of recombinant stromelysin (MMP-3) at a final concentration of 1.0 nM. Upon peptide cleavage, the fluorescent MCA group is detected using an excitation wavelength of 328 nanometers and an emission wavelength of 393 nanometers. The assay is linear from 0.2 to 5nM MMP-3 concentration and percent inhibition is calculated as described above for the primary thiopeptilide assay and IC50 values are determined by a linear regression analysis of percent inhibition versus log drug concentration. The peptide sequence of the MCA substrate, hereinafter designated P218, is shown below: MCA-Pro-Lys-Pro-Leu-Ala-Leu-DPA-Ala-Arg-NH2 P218 For MMP-3, this substrate has a K m of 16 μM at pH 6.5 and a kcat/K m value of 56,000M-lsec-l. Automated MMP Profiling Assay This assay is run with a protocol analogous to that reported for MMP-3 inhibition using the synthetic peptide P218 and each of the three enzymes and measuring quenched fluorescence. This assay can be run with each invention compound with the three enzymes MMP-3, MMP-9 and MMP-2 in parallel as adapted for a 96-well microtitre plate using a Hamilton AT ® workstation. LPS Induced TNFα Production in Mice The in vivo inhibitory properties of selected compounds can be determined using a murine LPS induced TNFα production in vivo model. BALB/c mice (Charles River Breeding Laboratories; Kingston, NY) in groups of ten are treated with either vehicle or compound. After one hour, endotoxin (E. coli lipopolysaccharide (LPS) 100 mg) is administered intraperitoneally (i.p.). After 90 min, animals are euthanized by carbon dioxide asphyxiation and plasma is obtained from individual animals by cardiac puncture into heparinized tubes. The samples are clarified by centrifugation at 12,500 x g for 5 min at 4 °C. The supernatants are decanted to new tubes, which are stored as needed at -20 °C. TNFα levels in sera are measured using a commercial murine TNF ELISA kit (Genzyme).
