Description

SUCCINAMIDAS DE HETEROARILO AND ITS USE AS INHIBITORS OF METALOPROTE INASA The matrix metalloproteinases ("MMPs") are a family of proteases (enzymes) involved in the degradation and remodeling of connective or conjunctive tissues. Members of this family of endopeptidase enzymes are secreted as proenzymes from various cell types that reside in or associate with the connective tissue, such as fibroblasts, monocytes, macrophages, endothelial cells and invasive tumor cells or tatic targets. MMP expression is stimulated by growth factors and cytokines in the local tissue environment, where these enzymes act to specifically degrade the protein components of the extracellular matrix, such as collagen, proteoglycans (protein core), fibronectin and laminin. These ubiquitous extracellular matrix components are present in the coatings of joints, interstitial connective tissues, basal membranes and cartilage. MMPs share several of the properties, which include zinc and calcium dependence, secretion as zymogens and 40-50% amino acid sequence homology. Eleven enzymes have been well characterized as MMP 's in humans, including three collagenases, three stromelysins, two gelatinases, matrilysin, metalloelae rate and membrane type MMP, as discussed in more detail below. The interstitial collagenases catalyze the initial decomposition or splitting and limiting ratio of types I, II and III of natural collagen. Collagen, the main structural protein of mammals, is an essential component of the matrix of many tissues, for example, cartilage, bone, tendon and skin. Interstitial collagenases are very specific matrix metalloproteases that break down these collagens to provide two agents that spontaneously denature at physiological temperatures and thus become susceptible to decomposition by fewer specific enzymes. Decomposition by collagenases results in the loss of structural integrity of the target tissue, an essentially irreversible process. Currently there are three known human collagenases, the first two are relatively well characterized (FASEB J., 5, 2145-54 (1991)). Fibroblast-like collagenase from human (HFC, MMP-1, or collagenase-1) is produced by a wide variety of cells including fibroblasts and macrophages. Human neutrophil type collagenase (HNC, MMP-8, or collagenase-2) has so far only been shown to be produced by neutrophils. Human collagenase-3 (MMP-13) is the most recently discovered member of this group of MMPs, which was originally found in breast or breast carcinomas (J. Bi ol. Ch em., 269, 16,766-16,773). (1994)), although it has already been shown to be produced by chondrocytes (J. Cl in. In ve st., 97, 761-768, 1996). Gelatinases include two distinct but highly related enzymes: a 72-kD enzyme (gelatinase A, HFG, MMP-2) secreted by fibroblasts and a wide variety of other cell types, and a 92-kD enzyme (gelatinase B, HNG , MMP-9) released by mononuclear phagocytes, neutrophils, corneal epithelial cells, tumor cells, cytotrophoblasts and keratinocytes. These gelatinases have been shown to degrade gelatins (denatured collagens), types IV of collagen (basement membrane) and V, fibronectin and insoluble elastin. Esterlysins 1 and 2 have been shown to decompose a wide range of matrix substrates, including laminin, fibronectin, proteoglycans, and collagen types IV and IX in their non-helical domains. Matrilysin (MMP-7, PUMP-1) has been shown to degrade a wide range of matrix substrates including proteoglycans, gelatins, fibronectin, elastin and laminin. Its expression has been documented in mononuclear phagocytes, explantations of uterine tissue in rats and sporadically in tumors. Other less characterized MMPs include metaloelas macrophage rate (MME), MMP-12), membrane type MMP (MMP-14) and stromelysin-3 (MMP-11). Excessive degradation of the extracellular matrix by MMPs is implicated in the pathogenesis of many diseases of both chronic and acute nature. For example, many studies, such as those reviewed in Exp. Opi n. In ves t. Drugs, 5, 323-335, (1996), have established that the expression and activation of MMPs are critical events in the growth, invasion and tumor metastasis. In addition, it has been shown that MMP activity is required for angiogenesis, which is necessary for tumor growth as well as for other pathological conditions such as macular degeneration. MMPs, especially stromelysin-1, collagenase-1 and collagenase-3, have been strongly implicated in the destruction of articular cartilage that is the hallmark of rheumatoid arthritis and osteoarthritis. See, for example, J. Clin. Invest., 97, 761-768 (1996). In addition, it is believed that tissue destruction associated with gingivitis and periodontal disease is mediated by overexpression of MMPs in response to proinflammatory cytokines. See Molecular Pathogenesis of Periodontal Say, Chapter 17, 191-202 (1994). Other diseases in which critical performances have been identified for MMPs include multiple sclerosis (J. Neuroimmunol., 41, 29-34 (1992)), corneal ulceration (Invest. Opthalmol and Visual Sci., 32, 1569-1575 ( 1989), apoplectic attack (Brain Research, 703, 151-155 (1995) and J. Cereb. Blood Flow Metab., 16, 360-366 (1996)), aging of the skin induced by the sun (Nature, 379 , 335-339 (1996)), chronic obstructive pulmonary disease such as emphysema (Am. J. Respir, Cell, Mol. Biol. 7, 5160-5165 (1994)), chronic ulceration (J. Clin. Invest., 94, 79-88 (1994)), cardiac arrhythmia and endometriosis. Finally, performances for MMP-mediated degradation of basal membranes have been proposed in the rupture of atherosclerotic plaques (Basic Res. Cardiol., 89 (SUPPL.l), 59-70, (1994)) and in the development of glomerular disease (J. Cl in. In ves t., 97, 1094-1101 (1996)). It is expected that the MMPs inhibitors provide useful treatments for the diseases described above in which the degradation of the extracellular matrix by MMPs contributes to the pathogenesis of the disease. In general, selective MMP inhibitors of particular subsets of MMPs may offer therapeutic advantages, as has been typically observed, that limited number of members of the MMP family is involved in any of the disease states listed above. For example, the involvement of individual collagenases in the degradation of tissue collagens is likely to be strongly dependent on the tissue. The tissue distribution of human collagenases suggests that collagenase-3 is the major contributor to the degradation of the cartilage collagen matrix, whereas collagenase-1 is more likely to be involved in tissue remodeling of the collagenase. skin and other soft tissues. In addition, stromelysin-1 appears to be largely responsible for the excessive loss of proteoglycan from cartilage. Thus, the inventive compounds described herein that are selective inhibitors for collagenase-3 and is thromelysin on collagenase-1, are preferred for the treatment of diseases associated with erosion of cartilage, such as rheumatoid arthritis and osteoarthritis. . Similarly, among MMPs, metalloelastase has been specifically implicated in the pathology of pulmonary emphysema. See J. Biol. Chem. 270, 14568-14575 (1995). The design and uses of MMP inhibitors were reviewed, for example, in J. Enzime Inhibition, 2, 1-22 (1987); Progress in Medicinal Chemistry 29, 271-334 (1992); Current Medicinal Chemistry, 2, 743-762 (1995); Exp. Opin. Ther. Patents, 5, 1287-1296 (1995); and in Drug Discovery Today, 1, 16-26 (1996). MMP inhibitors are also the subject of many patents and patent applications. In most of these publications, the preferred inventive compounds are hydroxamic acids, just as it has also been established that hydroxamate function is the optimal functionality for the coordination of zinc to bind the active site of the MMPs. For example, the hydroxamate inhibitors described in the literature are generally 100 to 1000 times more potent than the corresponding inhibitors, wherein the functionality of the hydroxamic acid is replaced by a carboxylic acid functionality. Despite this, hydroxamic acids tend to exhibit relatively poor bioavailability. The preferred compounds described herein are carboxylic acid inhibitors that possess inhibitory potency against MMPs that is comparable to the potency of the hydroxamic acid inhibitors that have been reported in the literature. The following patents and patent applications describe carboxylic acid inhibitors which are like the inventive carboxylic acid inhibitors described herein, substituted succinic acid monoamine derivatives: Celltech Ltd .: EP-A-0489577 (WO 92/099565), EP-A-0489579, WO 93/24475, WO 93/244449; British Biotech Pharmaceuticals Ltd .: WO 95/32944, WO 95/19961; Sterling Winthrop, Inc .: US 5,256,657; Sanofi Winthrop, Inc .: WO 95/22966; and Syntex (U.S.A.)

METHODS FOR PREPARING THE INHIBITORS OF METALOPROTEINASE CARBOXYLATE MATRIX VXX PREPARATION OF COMPOUNDS OF FORMULA I The methods for preparing compounds of Formula I, wherein R5 is carboxyl, culminate in the deprotection of the esters (1) to the corresponding carboxylates as illustrated in Scheme Reaction I in the following. Suitable types of esters (1) and decomposition of R5 are described, for example, in Greene, T; Wuts, P.G.M. "Protective Groups in Organic Synthesis", Wiley: 1991 and Kocienski, P.J. "Protecting Groups", Thieme: 1994, which are incorporated herein by reference. Some examples and conditions found here are given in the following.
REACTION SCHEME I (1) As an example of the decomposition of the typical ester, an ester of Formula (1), where Re is benzyl, is placed in a suspension with solvent, for example, ethyl acetate also containing metal catalyst, preferably palladium (0) in a source of hydrogen such as hydrogen gas at one atmosphere or higher, at room temperature for 30 minutes to three days, preferably four hours. The carboxylates of the formula I, where R 5 is -COOH, are subject to the usual isolation and purification. For the esters of the formula (1) wherein R6 is t-butyl, the ester (1) is deprotected in a solution of solvent, preferably chloroform or dichloromethane, with trifluoroacetic acid in excess, at room temperature for 15 minutes at 12 hours to obtain a carboxylate of Formula I. For the esters of the formula (1) wherein R6 is allyl, the ester (1) is subjected to decomposition in an inert solvent, preferably acetonitrile, with a catalytic amount of palladium catalyst, such as tetrakis (triphenylphosphine) -palladium (0), with an excess of secondary amine, such as morpholine, for 15 minutes at 12 hours at room temperature. Other protective strategies can be used where the above conditions are incompatible with the functional groups contained in either R4 or R5. For example, the simultaneous protection where R is olefinic and R5 is carboxylate can occur through its connection as in a halolactone of Formula (2) where X is halogen, as shown in Scheme Reaction II below. The halolactone (2) is subjected to reductive opening for the compounds of the formula I, wherein R 4 is allyl and Rs is carboxylate.
REACTION SCHEME II Preparation of the Compounds of Formula I, wherein R "is Allyl and Rs is Carboxylate A solution of halolactone (2) is exposed to a reductive environment, preferably zinc dust in excess zinc in acetic acid.

The compounds (5) of the Formula I wherein R5 is hydroxamic acid (-C (O) NHOH) can be obtained from the compounds (3) of the Formula I wherein R5 is carboxyl. Any of the many commercially available coupling reagents can be used for conversion to either a protected version of a compound of the formula (4) wherein R7 is alkyl or directly to hydroxamate (5), as indicated by the following Reaction Scheme III: REACTION SCHEME lll Step 1 - Preparation of the Compounds of the Formula (4) or (5) The carboxylic acids of the formula (3) and the hydroxylamine or its O-alkyl derivatives in inert solvent, preferably dimethylformamide (DMF), are coupled with any of the many available coupling reagents, preferably benzotriazol-1-yloxy tris- (dimethylamino) -phosphonium hexafluorophosphate (BOP), at room temperature for one to 24 hours to provide either the hydroxamates (5) or O-alkyl hydroxamates (4), respectively. The products are subject to the usual handling and purification.
Step 2 - Preparation of the Compounds of the Formula (5) from the Compounds of the Formula (4) The protected hydroxamates of the Formula (4) are deprotected as determined by the nature of the protecting group R7. Where R7 is a trialkylsilyl, hydrolysis with mild acid or decomposition with fluoride in protic or aprotic solvent at room temperature or lower for one to 12 hours is sufficient. Where R7 is benzyl, selective deprotection without decomposition of the N-O bond proceeds in the presence of palladium on carbon, with a source of hydrogen, such as hydrogen gas at atmospheric pressure, in a suitable solvent such as dimethylformamide or methanol.

A direct, analogous substitution of the heterocyclic ring involves the alkylation of an organometallic derivative of the Formula (53) wherein M is, for example, lithium, magnesium, or copper, with an a-haloacetic acid derivative of the Formula (50) , as shown in the following Reaction Scheme: REACTION SCHEME XXI (50) (40) Step 1 - Preparation of the Compounds of the Formula (53) The heterocyclic metallo derivatives of the Formula (53) are available in the usual manner from a heterocycle of the Formula (52). The main methods include deprotonation of the matrix of Formula (52) wherein W is hydrogen, or from the halogen-metal exchange of the corresponding halo-heterocycle of Formula (52) wherein W is halogen. These reactions are typically carried out in inert aprotic solvent such as tetrahydrofuran, at room temperature or below, from 15 minutes to 24 hours. The organometallics of the Formula (53) are usually unstable in contact with the atmosphere and humidity. They are formed in the usual way i n if t u and are used immediately without isolation.
Step 2 - Alternate Preparation of the Compounds of the Formula (40) The organometallics of the Formula (53) are alkylated by stoichiometric or excess amounts of acetate or acetamide of the Formula (50) in inert solvent, preferably tetrahydrofuran, at low temperature from -78 to 0 ° C, for ten to 90 minutes.

The disubstituted heterocycles of the Formula (40) can also be constructed in a differently ordered sequence: recent formation of the portion containing X and Ri by using the appropriate sequences of the coupling methods discussed in Reaction Schemes XIII, XIV, XV, and XVI. Many of the monosurbed heterocycles which are commercially available carry only one carbon in the substituent, and further processing is necessary to prepare the disubstituted heterocycles of Formula (40), as shown in the following Scheme of 'Reaction XIII. The commercially available mono-substituted heterocycles of the Formula (58), where Ru is hydrogen, hydroxy, or alkoxy (eg, 3-furan carboxaldehyde or 3-furfural, where Rn is hydrogen) can be homologated through any of several suitable methods known to those skilled in the art, for example, as described in Martin, SF Syn the si s 1979, 633-665, to provide the 2-heterocyclic acetic acid derivatives (59), which are they can be substituted additionally, for example as a halide of the Formula (60). Alternatively, the heterocycles of Formula (58) are substituted as halides of Formula (61), then homologated to the derivatives of Formula (60). Subsequent binding of a compound of Formula (60) with an appropriate coupling partner such as a compound of Formula (31) provides the esters or amides of Formula (62). As recognized by those skilled in the art, the versatility of the methods of Reaction Scheme XXIII allows the interchangeability of the stages. For example, substitution of the halides of Formula (61) with the boronic acids of Formula (31) may precede a homologation to the desired intermediates of Formula (62) (not shown).
REACTION SCHEME XXIII Step 1 - Preparation of the Compounds of the Formulas (59) and (60) The heterocycles of the Formulas (58) and (61) are homologous to the compounds of the Formulas (59) and (60), respectively, depending on the nature of Ru and R9.

The resulting heteroaryl halides of Formulas (60) and (61), respectively, are subjected to customary purification and handling.
Step 3- Preparations of the Compounds of the Formula (62) The coupling of the heteroaryls of the Formula (60) is carried out analogously to that described for Reaction Schemes XIII, XV, or XVI to obtain the compounds of the Formula (62). Amides with the generic Formula (40), where R9 is alkylamino, are often available from the corresponding carboxylic acid or corresponding activated esters of Formula (40) wherein R9 is alkoxy or hydroxy, as exemplified in the following Reaction Scheme XXIV: SSQUEMADE REACTIONXXIV The formation of the amides (64) (ie, the Formula (40) wherein R9 is alkylamine) results from the acids of the Formula (63) which are coupled with the amines of the Formula (10) under the same conditions described above for Reaction Scheme V, Step 2. The products of Formula (64) are isolated and purified by conventional methods. The oxazolidines of Formula (42) can be made from the acetamides of Formula (65) where Y, in the terms of Formula I, is -CH (OH) -, as shown in the following Reaction Scheme XXV: REACTION SCHEME XXV The hydroxyamides of Formula (65) are placed in a solution containing acetone or its equivalent, preferably 2-methoxypropene, with a catalytic amount of acid, such as p-toluenesulfonic acid, under dehydration conditions, such as entrapment of water. with a Dean-Stark apparatus, at room temperature at reflux, for an adequate amount of time to convert the starting materials (65). The product (42) is subject to the usual processing for isolation and purification.
A preferable way to reach the oxazolidines of Formula (42) involves the coupling of the oxazolidines of Formula (67) with the acetic acids of Formula (63), as shown in the following Reaction Scheme XXVI. The oxazolidines (67) in turn originate from amino-alcohols of the Formula (66) of commercial and synthetic origin.
REACTION SCHEME XXVI Step 1 - Preparation of the Compounds of the Formula (67) The compounds of the Formula (67) are prepared from the compounds of the Formula (66) using a method similar to that described above for the preparation of the compounds of Formula (42) of Reaction Scheme XXV, except that lower temperatures are preferred. The products of Formula (67) may be somewhat unstable and are used in the usual way i n if t u or immediately in the next reaction without purification.
Step 2 - Alternative Preparation of the Compounds of the Formula (42) Conditions for the formation of amides with typical coupling reagents as discussed above for Reaction Scheme V, Step 2, are applied for the preparation of the compounds of the Formula (42).

BIOLOGICAL DATA Isolation of MMPs for Analysis The catalytic domain of human collagenase-1 is expressed as a fusion protein with ubiquitin in E. col i (see Gehring, E.R., J Biol. Ch em., 1995, 270, 22507). After purification of the fusion protein, the catalytic domain of fibroblast collagenase-1 (HFC) is released either by treatment with active, purified-1 (1:50 ratio w / w), which generates almost 100% N-terminal Phel, or by self-processing the concentrated collagenase-1 fusion and then incubating at 37 ° C for 1 hour. The final purification is completed by using zinc chelate chromatography. The propeptide and the catalytic domain of human collagenase-3 (Coll3) is expressed in E. col i as an N-terminal fusion protein with ubiquitin. After purification of the fusion from the inclusion bodies, the catalytic domain is released by treatment with 2mM APMA at room temperature overnight. The final purification is completed by using copper chelate chromatography. The catalytic domain of human thromelysin (Hsln) is obtained by the expression and purification of a prostromelysin-1 terminally truncated with C from host BL21 of E. col i (see Marcy et al. Bi och em, 1991, 30, 6476). Subsequent activation of the mature form (Hsln) is completed with 2mM APMA for 1 hour at 37 ° C, followed by separation using a sizing column. Human matrilysin (Matr) is expressed in E. col i as a fusion protein with ubiquitin. After purification of the matrilysin / ubiquitin fusion from the inclusion bodies, the catalytic domain is released by treatment with 2mM APMA at 37 ° C for 2 hours. The final purification is completed by using copper chelate chromatography. The catalytic and fibronectin-like portion of human progelatinase A (GelA) is expressed as a fusion protein with ubiquitin in E. Col i. The analyzes are carried out in autocatalytically activated material. The compounds of Formula I exhibit the ability to inhibit MMPs when tested in the following analysis.
In Viral Analysis Procedure The analyzes are performed in analysis buffer (50 mM Tricine at pH 7.5, 200 mM sodium chloride, 10 mM calcium chloride, 0.5 mM zinc acetate, containing 2% dimethyl sulfoxide (DMSO) once the substrate and the inhibitor are diluted therein. The stock solutions of the inhibitors are prepared in 100% DMSO. The stock solutions of the substrate are prepared in 100% DMSO at a concentration of 6 mM. The method of analysis is based on the hydrolysis of MCA-Pro-Leu-Gly-Leu-DPA-Ala-Arg-NH2 (American Peptide Co.) at 37 ° C (see Knight, CG et al., FEBS, 1992, 296, 263-266). Fluorescence changes are monitored with a Perkin-Elmer LS-50B fluorimeter that uses an excitation wavelength of 328 nm and an emission wavelength of 393 nm. The substrate concentration used in the analyzes is 10 μM. The inhibitor is diluted in the analysis of a solution in 100% DMSO and the controls replace an equal volume of DMSO in such a way that the final concentration of DMSO, from the inhibitor and the dilution of the substrate in all the analyzes, is of 2%. The concentration of the enzyme in the analysis ranges from 60 pM for the gelatinase A to 1.5 nM for the thromelysin and is a function of the respective kcat / Km enzymes for the MCA peptide substrate. The proper determination of the steady state velocities of the substrate decomposition requires 60 minute analysis periods to allow complete equalization of the enzyme inhibitor complex. The Km for the peptide substrate of MCA with the matrix metalloproteinases is quite high and exceeds its solubility under analysis conditions. Therefore, the Kx (Ki, apparent app is determined to describe the inhibiting resistance.) However, in this case, K1 / app would be essentially equal to Kx after [S] «Km. For the determination of Kirapp, the concentration The inhibitor is varied to a constant and the low concentration of the substrate and the steady state rates of fluorescence change are determined.In the majority of cases no abrupt absorbent cooling is observed due to the presence of ligand. At low fixation, the inhibition initiation curves are ordered for at least 45 minutes in such a way that equilibrium is established.The steady state velocities of the fluorescence change are obtained by fitting a curve to an equation for a simple exponential decay that contains a linear phase.The adjusted value of the linear phase is taken as the steady-state velocity.The steady-state velocities are adjusted to the Michaelis equation that describes competitive inhibition by non-linear methods. The data resulting from the inhibition of tight fixation are analyzed and the Ki, app is determined by fitting the data to Morrison's narrow fixation equation (Bi och em Bi ophys. Ac ta, vol 185, p. 269-286 (1969)) by non-linear methods. The results of the tests described above are presented in the following Table 1.
TABLE 1 Determination of the Inhibitory Concentration in Plasma after Oral Dosing The dosing solution consists of the dissolved inhibitor in either a molar equivalent of HCl in water (vehicle A), in 60% propylene glycol ac. (vehicle B), or in 2.8 mg / mL of sodium bicarbonate in 60% aqueous propylene glycol (vehicle C), producing a final concentration ranging from 10-15 mg / ml. Sprague Dawley rats (Hilltop Lab Animáis, Scottsdale, PA) were dosed as a drug function in weight per body weight, usually 50 mg per kg. Blood is drawn from the rats and centrifuged, and the plasma is stored in the freezer. The drug is extracted from about 50 μl of aliquot of plasma to add 1 ml of acetonitrile, stirring for 2 minutes, centrifuging for 15 minutes at 4000 rpm, collecting the supernatant and then evaporating to dryness under a stream of nitrogen. The samples are reconstituted with 130 μl of mobile phase, shaken for 2 minutes and centrifuged for 15 minutes at 4000 rpm. the supernatant is collected and the samples are analyzed by injecting 100 μl of supernatant into CLAP.
The quantification of drug levels is carried out by generating a standard curve of known amounts of drug that are extracted from the aggregated plasma. Drug levels are plotted as a function of time and analyzed to provide the area under the curve (AUC) and the concentration values (Cmax). The results are shown in Table 2.
