Description: Use of Substituted 4-Biarylbutyric and 5-Biarylpentanoic Acid Derivatives as Matrix Metalloprotease Inhibitors for the Treatment of Respiratory Diseases Field This invention relates to the use of enzyme inhibitors, and more particularly, to new and known matrix metalloprotease-inhibiting 4-Biarylbutyric Acids and 5-Biarylpentanoic Acids and derivatives thereof, for the prevention and treatment of respiratory diseases. Background Substituted 4-Biarylbutyric and 5-Biarylpentanoic Acid Derivatives as Matrix Metalloprotease Inhibitors are described in WO 96/15096, WO 97/43237, WO 97/43238, WO 97/43239, WO 97/43240, WO 97/43245, WO 97/43247 and WO 98/22436. The matrix metalloproteases (matrix metalloendo-proteinases or MMPs) are a family of zinc endoproteinases which include, but are not limited to, interstitial collagenase (MMP-1), stromelysin (proteoglycanase, transin, or MMP-3), gelatinase A (72kDa- gelatinase or MMP-2), neutrophil collagenase (MMP-8), gelatinase B (95kDa- gelatinase or MMP-9), macrophage elastase (MMP- 12) and human collagenase 3 (MMP 13). These MMPs are secreted by a variety of cells including fibroblasts, chondrocytes, granulocytes and macrophages along with natural proteinatious inhibitors known as TIMPs (Tissue Inhibitor of MetalloProteinase). All of these MMPs are capable of destroying a variety of connective tissue components of articular cartilage or basement membranes and a wide variety of extracellular matrix proteins. 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, JJ. 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. In addition to its ability to degrade extracellular matrix proteins MMP- 12 has also been shown to hydrolyse elastin (R.P. Mecham, TJ. Broekelmann, C J. Fliszar, S.D. Shapiro, H.G. Welgus, R.M. Senior, J. Biol. Chem., 272, 18071-18076 (1997)). This activity is shared by other MMP enzymes, specifically MMP-2 and MMP-9. It has also been reported that MMP-3, MMP-9 and MMP- 12 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); TJ. Gronski, R.L. Martin, D.K. Kobayashi, B.C. Walsh, M.C. Holman, M. Huber, H.E. Van Wart, S.D. Shapiro, J. Biol. Chem., 272, 12189- 12194 (1997)). Inhibitors of these MMP enzymes could thus influence the activity of other destructive proteinases by modifying the level of their endogenous inhibitors. Macrophages from MMP- 12 knock-out mice have a diminished capacity to degrade extracellular matrix components and to penetrate reconstituted basement membranes both in vitro and in vivo (J.M. Shipley, R.L. Wesselschmidt, D.K. Kobayashi, TJ. Ley, S.D. Shapiro, PNAS, 93, 3942-3946 (1996)). These results support the hypothesis that MMP- 12 is required for macrophage mediated extracellular proteolysis and tissue invasion. In addition, MMP- 12 knock-out mice do not develop emphysema or show elevated macrophage levels in response to smoking, whereas wild type mice do (R.D. Hautamaki, D.K. Kobayashi, R.M. Senior, S.D. Shapiro, Science, 277, 2002-2004 (1997)). Therefore there is strong evidence supporting a role of MMP- 12, secreted by activated alveolar macrophages, in the development of pulmonary emphysema. In patients with emphysema and smoking subjects both MMP-1, -8, -9 and -12 released from alveolar macrophages and neutrophils are also implicated in the pathogenesis of COPD. By means of their proteolytic activity, matrix metallo-proteases are involved in a number of respiratory diseases, e.g. the following: asthma; chronic obstructive pulmonary disease including chronic bronchitis and emphysema; cystic fibrosis; bronchiectasis; adult respiratory distress syndrom (ARDS); allergic respiratory disease including allergic rhinitis; diseases linked to TNF α production including acute pulmonary fibrotic diseases, pulmonary sarcoidosis, silicosis, coal worker's pneumoconiosis, alveolar injury. Evidence for the involvement of matrix metalloproteases in various respiratory diseases is provided by the following references: a) COPD, chronic - Finlay et al.

In addition to chronic lung diseases a number of other conditions are thought to be mediated by excess or undesired matrix-destroying metalloprotease activity or by an imbalance in the ratio of the MMPs to the TIMPs or through the action of the release of TNF. MMP inhibitors may also be useful in the inhibition of other mammalian metalloproteases such as the adamalysin family (or ADAMs) whose members include TNF α converting enzyme (TACE) and ADAM- 10, which can cause the release of TNF from cells. Summary This invention relates to the use for the prevention and treatment of respiratory diseases of new and known compounds having matrix metallprotease inhibitory activity of the generalized formula (I) : (T) x A-B-D-E-CO 2 H (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.

Rings may be formed in two ways: a) two groups R^ are joined, and taken together with the chain atom(s) to which the two R6 group(s) are attached, and any intervening chain atoms, constitute a 3 - 7 membered ring, or b) one group R^ is joined to the chain on which this one group resides, and taken together with the chain atom(s) to which the R^ group is attached, and any intervening chain atoms, constitutes a 3 - 7 membered ring. The number n of carbon atoms in the chain is 2 to 4, and the number m of R^ substituents is an integer of 1 - 3. Each group R6 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^, wherein t is 0 or an integer of 1 - 5 and R? is selected from the group consisting of: *N-phthalimidoyl; *N-(1 ,2-naphthalenedicarboximidoyl); *N-(2,3-naphthalenedicarboximidoyl); *N-(l,8-naphthalenedicarboximidoyl); *N-indoloyl; *N-(2-pyrrolodinonyl); *N-succinimidoyl; *N-maleimidoyl; *3-hydantoinyl; *l,2,4-urazolyl; *amido; *urethane; *urea; *nonaromatic substituted or unsubstituted heterocycles containing and connected through a N atom, and comprising one or two additional N, O, S, SO, or SO2, and containing zero, one or two carbonyls, and optionally bearing a fused benzene or pyridine ring; * amino; * 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; *-(CH2)vZR8 in which v is 0 or an integer of 1 - 4, wherein Z represents and R% is selected from the group consisting of: * alkyl; *aryl; *heteroaryl; * arylalkyl; * heteroaryl-alkyl; and *-C(O)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 R 8 is -C(O)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.

Pharmaceutically acceptable salts of these compounds as well as commonly used prodrugs of these compounds such as O-acyl derivatives of invention compounds which contain hydroxy groups are also within the scope of the invention. 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. The compounds of the present invention exhibit good activity for MMP-2, MMP-3, MMP-8, MMP-9, MMP-12 and MMP-13, and a good selectivity for these MMP's over other MMP's such as MMP-1 and MMP-7. In addition to the above-described compounds, the invention also relates to pharmaceutical compositions having matrix metalloprotease inhibitory activity, which compositions comprise a compound of the invention as described above and in more detail in the detailed description below, and a pharmaceutically acceptable carrier. As a result of the abovementioned selectivity profile, the compounds of the present invention are especially suitable for the treatment of respiratory diseases. Therefore, the invention also relates to a method of treating a mammal such as a human, a farm animal, or a domestic pet, to achieve an effect, in which the effect is: treatment and prevention of asthma; chronic obstructive pulmonary disease including chronic bronchitis and emphysema; cystic fibrosis; bronchiectasis; adult respiratory distress syndrome (ARDS); allergic respiratory disease including allergic rhinitis; diseases linked to TNF α production including acute pulmonary fibrotic diseases, pulmonary sarcoidosis, silicosis, coal worker's pneumoconiosis, alveolar injury; the method comprising administering an amount of a compound of the invention as described above, and in more detail in the detailed description below, which is effective to inhibit the activity of at least one matrix metalloprotease, resulting in achievement of the desired effect.

When A unit is thiophene, it is preferably connected to B unit at position 2 and carries one substituent group T on position 5. When B Unit is thiophene, it is preferably connected through positions 2 and 5 to D and A units respectively. In another embodiment, the invention relates to compounds of generalized formula (I), in the E unit of which n is 2 and m is 1. These compounds thus possess two carbon atoms between the D unit and carboxyl group, and carry one substituent on this two-carbon chain. In another of its embodiments, the invention relates to compounds of generalized formula (I) in which the A ring is a substituted or unsubstituted phenyl group, the B ring is p-phenylene, and aryl portions of any aryl-containing T and R" moieties contain only carbon in the rings. These compounds thus contain no heteroaromatic rings. In another of its embodiments, the invention relates to compounds of generalized formula (I) in which m is 1 and R > is an independent substituent. These compounds are materials which contain only a single substituent R° on the E unit, and this substituent in not involved in a ring. Preferred compounds of general formula (I) in which Rβ is -(CH2)tR^ have t as an integer of 1-5. Preferred compounds of general formula (I) in which Rβ is -(CH2)vZR 8 have v as an integer of 1-4 and Z as -S- or -O-. Preferred compounds of general formula (I) in which R^ is alkyl contain 4 or more carbons in said alkyl and those in which R^ is arylalkyl contain 2-3 carbons in the alkyl portion of said arylalkyl. 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 2 or 3; and when m is 2, both groups β are independent substituents, or together constitute a spiro ring, or one group R > is an independent substituent and the other constitutes a spiro ring; and when m is 3, two groups R > are independent substituents and one group R^ constitutes a ring, or two groups R^ constitute a ring and one group R^ is an independent substituent, or three groups R6 are independent substituents. This subset therefore contains compounds in which the E unit is di- or tri substituted, and in the disubstituted case any rings formed by one or both R^ groups are spiro rings, and in the trisubstituted case, the R^ groups may form either spiro or nonspiro rings. 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 R^ constitutes a nonspiro ring; and when m is 2, both groups R" together constitute a nonspiro ring or one group 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 R^, 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^ is 0, 1, or 2; U represents O, S, or NRl; and z is 1 or 2; Each group R 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)R2; -CO2R 3 ; -CON(R 2 )2; -(CH2)tR 7 in which t is 0 or an integer of 1 - 4; and -(CH2)vZR in which v is 0 or an integer of 1 to 3, and Z represents -S-, S(O), SO2 . or -O-. Rl, R7, and R * have been defined above. Other preferred 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, b, c, d, (c + d), e, g, i, k, the total number of groups R^, U, and R^ 4 are as defined above. Other preferred compounds for the use for the prevention and treatment of respiratory diseases of generalized formula (I), in which one or more of the substituent groups R6 are involved in formation of nonspiro rings have the formula in which the subscript x is 1 or 2; one substituent T is located on the 4-position of the A ring, relative to the point of attachment between the A and B rings; e is 2 or 3; and R* 4 is as defined above. More preferred compounds are those shown in table 1 : table 1 In the above structures, the term "racemate" in case of the cyclopentane derivatives refers to the trans, trans-diastereomer, that is, e.g. for examples C-VII, C-XI, C-XVI to C-XVIII and C-XXIX to C-XXXV a 1S R, 2S/R, 5R/S relationship. Especially preferred is the use of the following compound: (+)-4-(4'-chloro[l,l'-biphenyl]-4-yl)-2-[2-(l,3-dioxo-l,3-dihydro-2H-isoindol-2- yl)ethyl]-4-oxobutanoic acid In another aspect of the invention the following new compounds of the general formula (V) are provided, wherein CO-E-CO 2 H represents a 3-carboxyl-5-R 7 -pentan-l-on-l-yl- residue and the substituents T and R 7 have the meaning indicated in the following table: table 2 Especially preferred is the following compound: (+)-2-[2-(l ,3-dioxo- 1 ,3-dihydro-2H-isoindol-2-yl)ethyl-4-(4'-ethoxy [ 1 , 1 '-biphenyl]- 4-yl)-4-oxobutanic acid In another aspect of the invention, use of compounds of the general formula (!') wherein T is (C r C 4 )-alkoxy, chloride, bromide, fluoride, acetoxy, hydroxy, cyano, trifluoromethyl or trifluoromethoxy, CO-E-CO 2 H represents a 3-carboxyl-5-R 7 -pentan-l-on-l-yl- or a 2- carboxy 1-3 -(R 7 -methyl)-cyclopentan- 1 -yl)carbonyl-residue, and R 7 represents a group of the formula and their salts, is a preferred embodiment. Especially preferred is the use of the following compound: (+)-2-[2-(l ,3-dioxo-l ,3-dihydro-2H-isoindol-2-yl)ethyl]-4-(4'-ethoxy[l , 1 '-biphenyl]- 4-yl)-4-oxobutanoic acid, General Preparative Methods: The compounds of the invention may be prepared by use of known chemical reactions and procedures as described in details in WO 96/15096, WO 97/43237, WO 97/43238, WO 97/43239, WO 97/43240, WO 97/43245, WO97/43247 and WO 98/22436. Nevertheless, the following general preparative methods are presented to aid the reader in synthesizing the inhibitors. 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. These general methods are also found in WO 9615096 (23 May, 1996) along with exemplary preparations of the keto acids. 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 R^ 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 R^ groups are used as if their definition includes H, to show where such R" groups may exist in the structures, and for ease in drawing. No change in the definition of R^ is intended by this non-standard usage, however. Thus, only for puφoses of the general method schemes below, R^ 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 III 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). Method A If the anhydride III is monosubstituted or multiplesubstituted 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 III 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 diacid and then conversion 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 R* 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 III (R6 = 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 R^ 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 III- 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^ 4 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-(tri-methyl- silyl)ethyl ester. The resultant intermediate with R^ 4 = CH2OH can be converted to key intermediates with other R* 4 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 l-cyclopentene-1,2- 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 R6 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 VIII 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 Rl as alkyl are obtained, and using more than two equivalents of base the acid compounds (R = H) are obtained. Optionally, heat is not used and the diacid or acid-ester I-B-l is obtained. Alternatively, the diester intermediate IX can be heated with a strong acid such as concentrated hydrochloric acid in acetic acid in a sealed tube at about 110 °C for about 24 hr to yield I-B-2 (Rl2 = H). Alternatively, the reaction of VI with VIII can be conducted before that with the alkyl halide to yield the same IX (Method B-2). Intermediates VIII 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 VIII (X = Br). Method B has the advantage of yielding single regio isomers whereas Method A yields mixtures. Method B is especially useful when the side chains R^ 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. Eng 30 (1991) No. 12). The key intermediates are prepared as pure enantiomers by use of a chiral auxiliary route - see, for example: D.A. Evans, Aldrichimica Acta, 5(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 XIII to yield pure isomer XIV. The use of opposite chirality XI yields opposite chirality XIV. Conversion of XIV to the enantiomerically pure diacid 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 III-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 succinic 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 acid 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 XV XIV ra-A I-C-l General Method D - Key intermediates in which R6 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-1 or I-D-5 are then reacted with a mercapto derivative XVII or XVIII in the presence of a catalyst such as potassium carbonate, ethyldiiso-butyl- amine, tetrabutylammonium fluoride or free radical initiators such as azobisiso- butyronitrile (AIBN) in a solvent such as dimethylformamide or tetrahydrofiirane to yield key intermediates I-D-2, 1-D-3, 1-D-6 or I-D-7. Method D XVI I-D-1 n is 1 or 2 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-l, which in turn is reacted with either of mercapto derivatives XVII or XVIII 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-l (R6 = H) with CH3I/DBU followed by reagent XXI and AgF and then basic hydrolysis yields pyrrolidine key intermediate I-E-5. R^ 4 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 R* 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(II) 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) Λ— Met + X-B-D-E-C0 2 H * (T) A-B-D-E-CO,H XXII XX... ∞ m ,-F T, x, A, B, E and D as in Structure I Met = Metal and X = Halide or Triflate or Met = Halide or Triflate and X = Metal General Method G - When the R^ groups of method F form together a 4 - 7 membered carbocyclic ring as in Intermediate XXN 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^ 4 is alkyl or arylalkyl are prepared according to method H. Starting material XXNII is reacted with two equivalents of a strong base such as lithium diisopropylamide (LDA) followed by an alkyl or arylalkyl halide (R^ 4 X) to yield intermediate XXVIII. 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 THF at reflux to yield XXIX. Hydrolysis of the ester with aqueous base followed by amide formation with R 1 OΝHR 12 (R is (C,-C 4 )-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 acid 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 acid to yield key intermediate I-H which is purified by chromatography on silica gel to afford pure isomers. Method H n = l - 4 XXVIII XXVII 1) Reduction 2) Dehydration 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 acid 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 XXXNIII, 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 acid or the like) leads to aldehyde XXXXIII. Reaction of this aldehyde with a biphenyl organometallic such as XXXII yields alcohol XXXXI V. Deblocking of the silyl group with, for example, tetrabutyl- ammonium fluoride followed by oxidation with, for example, pyridiniumdichromate or the like yields key intermediate 1-1-1 in which R^ 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 Ν-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 R^ 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 XXXXVII, if not available from commercial sources, are prepared by reaction of an activated biphenyl- carboxylic acid 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 XXXXVIII 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 R6 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 acid. This method is especially useful if any of the groups R^ contain aromatic residues. Method J XXXXV Method K - The key intermediates in which two R^ groups are joined to form a substituted 5-member ring are most conveniently prepared by method K. In this method acid LII (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 LIII is converted to its Grignard reagent by treatment with magnesium which is then reacted with LII 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 LIII is converted to a trimethyltin intermediate via initial metallation of the bromide with n-butyllithium at low temperature (-78°C) followed by treatment with chlorotrimethyltin and LII 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 LVI. Alternatively treatment with Osθ4 followed by HIO4 converts LV to LVI. 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 = OR2). In each case a final step is removal of acid blocking group R to yield acids (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 tetrabutylammonium fluoride. Method K LV Ozone then methylsulfide 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 NN-dibenzylethylenediamine, lower alkylamines such as methylamine, t-butylamine, procaine, lower alkylpiperidines such as N-ethyl- piperidine, 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. 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-2, MMP-3, MMP-8, MMP-9, MMP-12, MMP-13, and the related protease TACE, as well as the release of TNF 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 R" 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 compounds of the present invention exhibit good activity for MMP-2, MMP-3, MMP-8, MMP-9, MMP-12 and MMP-13, and a good selectivity for these MMP's over other MMP's such as MMP-1 and MMP-7. As a result of the abovementioned selectivity profile, the compounds of the present invention are especially suitable for the treatment of respiratory diseases. 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 include 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 include, 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 transgenic animals) or are induced by administration of exogenous agents or by surgery which disrupts joint stability. Biological Protocols Inhibitory activities of the compounds of the invention against matrix metalloproteases and production of TNFα may be determined as described below. P218 Quenched Fluorescence Assay for MMP Inhibition: This assay is adapted from the one described by Knight et al., FEBS Letters, 296, 263-266 (1992) for MMP-3 and a related substrate. - The rate of hydrolysis of the synthetic substrate H-MCA-Pro-Lys-Pro-Leu-Ala-Leu-DPA-Ala-Arg-NH 2 (P218) by the respective MMPs is monitored fiuorometrically, using an excitation wavelength of 340 nm and an emission wavelength of 395 nm, in the presence or absence of the test compounds. The substrate is made up initially in 100% DMSO to a concentration of 1 x 10 "2 M, then diluted in assay buffer to a final concentration of 20 μM. Test compounds (10 mM in DMSO) are diluted in assay buffer at an initial concentration of 0.3-1000 nM. These are diluted to a final concentration in the assay from 0.03 nM to 100 nM. The reaction is initiated by the addition of substrate at a final concentration of 20 μM. The total assay volume in a 96 well microtitre plate is 150 μl. Cleavage of the substrate between the Leu- Ala residues allows the fluorescence of the MCA group to be detected on a fluorometer (Cytofluor II) following excitation at 340 nm and emission at 395 nm. Change in fluorescence is continually monitored for a 40 min period. The Kj's are calculated using the method described by Williams and Morrison, Methods in Enzymology, 63, 437-467 (1979) to measure Kj apparent for tight binding inhibitors, and is summarised as follows: [I] 0 / (1 -Vj v 0 ) = K, apparent x vj / v 0 + [E] 0 [I] 0 and [E] 0 are inhibitor and enzyme concentrations, and v ; / v 0 are reaction velocities with / without inhibitor. [I] 0 is equal to IC 50 when Vj is half v 0 , so that: IC 50 = 0.5 x [E] 0 + K i ! apparent IC 50 's are determined at each enzyme concentration using Xlfit software. K ( apparent is then determined graphically from the plot of IC 50 versus MMP concentration, using the intercepts to estimate PC, apparent . Thus, intercept values at IC 50 = 0 and [E] 0 = 0 are equal to -2 x IC, apparent and IC, apparent , respectively. IC 50 values are calculated using % inhibition values at each enzyme concentration, ensuring data is taken from the linear part of the reaction rate curves. The Kj can then be calculated from the equation: K; = K; - g -^- grt / (1+SyK g where S = substrate concentration and K^ = dissociation constant. The assay conditions are modified as follows for each of the MMPs used: MMP-1 (human gingival fibroblast interstitial collagenase) Pro-MMP-1 was supplied by Jack Windsor [Windsor et al., J. Biol.

K,,, value: 22 μM Assay Buffer: The assay is carried out in buffer containing 50mM HEPES, 150mM NaCl, lOmM CaCl 2 , 0.005% Brij-35, pH 7.0. Enzyme concentrations for IC 50 determinations: 0.38 μg/ml Enzyme concentrations for I , determinations: 0.38 - 1.00 μg/ml MMP-12 (macrophage elastase) MMP-9 is isolated according to the following procedure: Human GenePool cDNA libraries from human lung, spleen, and brain were obtained from Invitrogen (Groningen, The Netherlands). HPLC-purified oligonucleotides were purchased from BioTez (Berlin, Germany), E. coli strain DH5α from Life Technologies (Heidelberg, Germany), strain BL21(DE3) from Novagen (Heidelberg, Germany). Pfu DNA- Polymerase and pBlueScriptII-KS(+) were from Stratagene (Heidelberg, Germany). DNA plasmid and DANN gel isolation kits were purchased from Qiagen (Hilden, Germany). All restriction enzymes and DNA modifying enzymes were ordered from New England Biolabs (Schwalbach, Germany). HiTrapQ (5ml) was from Pharmacia Biotech (Freiburg, Germany). Vydac C4-RP HPLC columns (214TP54: 300 A, 5 μm, 4.6x250 mm; 214TP1022: 300A, lOμm, 22x250mm) were from Promochem (Wesel, Germany). Fluorogenic substrate P218 was purchased from Polypeptide Laboratories (Wolfenbϋttel, Germany). Ultrapure urea was purchased from Schwarz- Mann (Cleveland, OH). Ready-to-use NuPAGE 10% Bis-Tris Polyacrylamide SDS- PAGE gels and NuPAGE 20x MOPS running buffer were obtained from Novex (Frankfurt Main, Germany) 10% AMPA and all other chemicals were from Sigma (Deisenhofen, Germany). Molecular Cloning of MMP-12: The CDS for human MMP- 12 (GenBank accession number: L23808; SwissProt accession number: P39900) was cloned by PCR out of the human normal spleen cDNA library with the gene-specific primers Oligo-428 (forward primer with BamHI -site underlined: 5'-aaa ttt aaa gga tec gcc ace atg aag ttt ctt eta ata ctg etc ctg-3') and Oligo-431 (reverse primer with EcoRI -site underlined: 5 '-aaa ttt aaa gaa ttc art aac aac caa ace age tat tgc ttt tca-3'). Removal of an internal EcoRI -site was done by PCR-mutagenesis with Oligo-434 (mutated base underlined: 5 '-gcc tec tga atg tgt agt cca gaa etc gtc etc ate gaa atg tgc atc-3'. The PCR reaction (lOOμl volume) was carried out with Pfu DNA-polymerase in a Perkin Elmer GeneAmp 2400 PCR system with 25 cylces of denaturation (94°C, 1 min), annealing (60°C, 1 min) and extension (72°C, 2 min). The PCR product was gel purified by electrophoresis on 0.8% agarose EthBr gels, separated from the agarose gel with the QiaEx2 DNA-isolation kit, cleaved with the restriction endonucleases Bam Hl EcoRl, and purified again. This material was ligated into the cloning vector pBlueScriptII-KS(+), which was previously digested with BamHI and EcoRI -cut and dephosphorylated with calf intestine alkaline phosphatase. The recombinant plasmid (pMYZ180) was transformed into E. coli strain DH5α. Plasmid DNA from several clones was isolated with the Qiagen plasmid preparation kit and analyzed by restriction digest. The DNA sequence of the MMP- 12 complete CDS was determined by the dideoxy sequencing with dye terminator chemistry on an ABI 377 sequencer. Sequence analysis and all subsequent bioinformatic work was done with the software package Lasergene from DNAStar (Madison, WI). Sequence analysis of construct pMYZ 180 (4369 bp) identified silent mutations in the CDS of MMP- 12 at positions 802 (G->A), 1402 (T->C), 1429 (C->T) and 2002 (T->C), which left the amino acid sequence of the protein unaffected. Construction of Expression Vectors: In order to test the best strategy for both protein expression and protein purification, several different expression constructs with either full-length or partial sequences of the MMP- 12 gene plus various affinity tags for purification were generated by PCR. The following constructs were made: pMYZ187: The coding sequence for full-length human MMP- 12 was cleaved via BamHl/EcoRl digest out of pMYZ180, ligated into BamHl/EcoRl cleaved pET- 28a, and the

Bacterial Expression: Batches of one liter of LB medium (10 g tryptone, 5 g yeast extract, 10 g NaCl) containing ampicillin (200μg/ml) or kanamycin (lOOμg/ml) were inoculated with 20 ml each of overnight culture of E. coli BL21(DE3) cells with the appropriate expression vector. Cells were cultured at 37°C to an OD600 of about 0.8 before induction with IPTG (1 mM final concentration). Incubation was continued at 37°C for 4 hours before harvesting by centrifugation. Cell pellets were frozen immediately and kept at -20°C until use. Aliquots (lOOμl) were taken from each cell culture and analyzed for protein expression on 10% SDS-PAGE gels. Protein Purification: Frozen cell pellets from 1 liter bacterial cells were thawed, dissolved in 50 ml Tris/HCl, pH 8.0 with 15 % glycerol, sonicated with 4 pulses a 10 sec and centrifuged for 30 min at 20,000 rpm with a JA-20 rotor. After removal of the supernatant, the inclusion bodies in the pellet were dissolved over night at room temperature with 50 ml 8M urea, 50mM Tris/HCl, pH 8.0 upon gentle shaking. The next day, the solution was centrifuged for 30 min at 20,000 rpm with a JA-20 rotor and the supernatant used for further purification. Batches of 5-10 ml were applied to a 5ml HiTrapQ ion exchange column running in 8M urea, 50mM Tris/HCl, pH 8.0 (buffer A). After sample loading and washing of the column, protein was eluted by increasing the salt concentration with a solution of 8M urea, 50mM Tris HCl, pH 8.0 + 1.0 M NaCl (buffer B) in a linear gradient of 0-50 % buffer B within 40 column volumes. Fractions with protein elution at around 30% buffer B were tested for purity by denaturing SDS-PAGE and mass spectrometry, and the fractions containing MMP-12 were pooled together. From this solution, 5-10 ml batches were taken, acidified to a final concentration of 10% acetic acid, and injected onto a preparative C4-RP-HPLC column (Vydac 214TP1022: 30θA, lOμm, 22x250mm) with a flow rate of 10 ml/min on a Waters HPLC chromatography workstation. Starting buffer was H 2 0/0.1% TFA (buffer A), and elution buffer was 90% CH 3 CN/ 10% H 2 0/ 0.1% TFA (buffer B). The pure protein eluted as a single peak at around 35%) buffer B and the protein containing fractions were again analyzed by denaturing SDS-PAGE and mass-spectrometry. Pooled fractions with MMP- 12 protein were frozen in liquid N 2 and freeze-dried for 3-5 days. Lyophilized protein was stored at -20°C. K^ value: 5.4 μM Assay Buffer: The assay is carried out in buffer containing 50 mM HEPES and 10 mM CaCl 2 , pH 7.0.
