Inhibitors of factor Xa and other serine proteases involved in the coagulation cascade

Description

FIELD OF THE INVENTION

[0001] The present invention relates to amino acid derivatives which display inhibitory effects of the serine protease factor Xa. The invention also discloses methods for the preparation of the compounds, pharmaceutically acceptable salts of the compounds, pharmaceutically acceptable compositions comprising the compounds or their salts, and methods of using them as therapeutic agents for treating or preventing disease states in mammals characterized by abnormal thrombosis.

BACKGROUND OF THE INVENTION

[0002] In economically developed countries, cardiovascular disease represents a major cause of mortality. In particular, abnormal coagulation and inappropriate thrombus formation within blood vessels precipitates many acute cardiovascular disease states. While it has long been recognized that a variety of plasma proteins such as fibrinogen, serine proteases, and cellular receptors are involved in hemostasis, it is abnormal regulation that has emerged as important contributing factors to cardiovascular disease.

[0003] Thrombin can be considered the key or principal regulatory enzyme in the coagulation cascade; it serves a pluralistic role as both a positive and negative feedback regulator in normal hemostasis. However, in some pathologic conditions, the positive feedback regulation is amplified through catalytic activation of cofactors required for thrombin generation. Such cofactors include factor Xa, a serine protease which occupies a pivotal position in the coagulation cascade. Factor X is the zymogen of factor Xa. Factor X can be activated either the intrinsic or extrinsic pathways of the coagulation system. Initiation of coagulation by either pathway in response to vascular injury activates factor X to factor Xa. Factor Xa and its cofactor, factor Va, combine on a phospholipid membrane to form the “prothombinase” complex, which activates prothrombin to thrombin. Thrombin cleaves fibrinogen to fibrin, activates platelets, and converts factor XIII to XIIIa which is the principal enzyme involved in thrombus generation, growth, and stabilization. Accordingly, the location of the prothrombinase complex at the convergence of both the intrinsic and extrinsic coagulation pathways suggests that inhibition of factor Xa, and hence thrombin generation, may be a viable approach to limiting the procoagulant activity of thrombin.

[0004] Evidence exists for the role of factor Xa inhibitors as anticoagulants. Antistasin, a potent inhibitor of blood coagulation factor Xa from the Mexican leech, Haementeria officinalis, displays antithrombotic activity in various models of arterial and venous thrombosis (Lapatto et al., Embo. J, 1997:5151-5161). Other protein or polypeptide factor Xa inhibitors include recombinant tick anticoagulant peptide (rTAP), which is known to accelerate the recombinant tissue plasminogen activator mediated clot lysis and prevent acute reocclusion in the dog, hence indicating factor Xa inhibitors may be useful as an adjunct to thrombolytic therapy (Mellott et al., Fibrinolysis, 1993: 195-202). Furthermore, in a canine coronary artery electrolytic lesion model, rTAP was demonstrated to reduce thrombus mass and time to occlusion in the absence of dramatic hemodynamic or hemostatic changes indicating the primary role for factor Xa in the process of arterial thrombosis (Lynch et al., Thromb. Haemostasis, 1995:640-645; Schaffer et al., Circulation, 1991: 1741- 1748). On the venous side, rTAP was also demonstrated to reduce fibrin deposition in a rabbit model of venous thrombosis while having little affect on systemic hemostatic parameters (Fioravanti et al., Thromb. Res., 1993: 317-324). In addition to these relatively high molecular weight proteins that are not suitable as oral antithrombotic agents, there also exist examples of low molecular weight factor Xa inhibitors. In particular DX9065a, a low molecular weight synthetic factor Xa inhibitor, has also shown antithrombotic potential in various experimental thrombosis rat models. In both arteriovenous shunt and venous stasis models, inhibition of thrombus formation was achieved at doses that had little effect on APTT, indicating that DX9065a is effective in preventing thrombosis and hence has therapeutic antithrombotic potential (Wong et al., Thromb. Res., 1996: 117-126).

[0005] Recently, it has been appreciated that factor Xa inhibition may provide sustained antithrombotic protection. Specifically, several animal studies show that inhibition of short term exposure to factor Xa produces a sustained antithrombotic effect. (Leadley, Curr. Top. Med. Chem., 2001: v. 1, 151-159.) Finally, the article by Leadley observes that factor Xa inhibition potentially provides a large therapeutical window between antithrombotic efficacy and bleeding tendency. Consequently, there may exist a range in which factor Xa inhibition is achieved without a concurrent increase in a paitents susceptibility to bleeding.

[0006] The majority of factor Xa inhibitors known to date have been summarized in two reviews (Edmunds et al., Annual Reports in Medicinal Chemistry, 1996:51 and Kunitada and Nagahara, Curr. Pharm. Des., 1996:531-542). However, it is readily apparent that there still exists a need for more effective agents that regulate factor Xa proteolytic activity.

[0326] Also provided by this invention, is a method for preventing and treating acute, subacute, and chronic thrombotic disorder in a mammal comprising administering to such mammal an therapeutically effective amount of a compound of Formula I. The compounds are useful as anticoagulants for the treatment and prevention of disorders such as venous and arterial thrombosis, pulmonary embolism, and ischemic events such as myocardial infarction or cerebral infarction. These compounds also have therapeutic utility for the prevention and treatment of complications of indwelling vascular access ports and arteriovenous shunts and coagulopathies associated with cardiopulmonary bypass or other extracorporeal systems. These compounds are useful for preventing or treating unstable angina, refractory angina, intermittent claudication, disseminated intravascular coagulation, and ocular buildup of fibrin. Since thrombin and serine proteases have also been demonstrated to activate a number of different cell types, these compounds are useful for the treatment or prophylaxis of septic shock and other inflammatory responses such as acute or chronic atherosclerosis. The compounds also have utility in treating neoplasia/metastasis and neurodegenerative diseases such as Alzheimer's and Parkinson's disease. In a preferred method, the thrombotic disorder is selected from venous thrombosis, arterial thrombosis, pulmonary embolism, myocardial infarction, cerebral infarction, angina, cancer, diabetes. A further embodiment of this invention is a pharmaceutical formulation comprising a compound of Formula I administered with a diluent, excipient, or carrier thereof.

[0327] The compounds of the present invention can be administered to a patient alone or as part of a composition that contains other components such as excipients, diluents, and carriers, all of which are well-known in the art. The compounds of Formula I can be Formulated as pharmaceutical compositions and administered to a mammalian host, such as a human patient in a variety of forms adapted to the chosen route of administration, i.e., orally or parenterally, by intravenous, intramuscular, topical or subcutaneous routes. The compositions can be administered to humans and/or animals either orally, rectally, parenterally (intravenously, intramuscularly, or subcutaneously), intracisternally, intravaginally, intraperitoneally, intravesically, locally (powders, ointments, or drops), or as a buccal or nasal spray. Such compositions and preparations should contain at least 0.1% of active compound. The percentage of the compositions and preparations may, of course, be varied and may conveniently be between about 2 to about 60% of the weight of a given unit dosage form. The amount of active compound in such therapeutically useful compositions is such that an effective dosage level will be obtained.

[0328] Compositions suitable for parenteral injection may comprise physiologically acceptable sterile aqueous or nonaqueous solutions, dispersions, suspensions or emulsions, and sterile powders for reconstitution into sterile injectable solutions or dispersions. Examples of suitable aqueous and nonaqueous carriers, diluents, solvents or vehicles include water, ethanol, polyols (propyleneglycol, polyethyleneglycol, glycerol, and the like), suitable mixtures thereof, vegetable oils (such as olive oil), and injectable organic esters such as ethyl oleate. Proper fluidity can be maintained, for example, by the use of a coating such as lecithin, by the maintenance of the required particle size in the case of dispersions and by the use of surfactants.

[0329] These compositions may also contain adjuvants such as preserving, wetting, emulsifying, and dispensing agents. Prevention of the action of microorganisms can be ensured by various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, sorbic acid, and the like. It may also be desirable to include isotonic agents, for example sugars, sodium chloride, and the like. Prolonged absorption of the injectable pharmaceutical form can be brought about by the use of agents delaying absorption, for example, aluminum monostearate and gelatin.

[0330] Solid dosage forms for oral administration include capsules, tablets, pills, powders, and granules. In such solid dosage forms, the active compound is admixed with at least one inert customary excipient (or carrier) such as sodium citrate or dicalcium phosphate or (a) fillers or extenders, as for example, starches, lactose, sucrose, glucose, mannitol, and silicic acid; (b) binders, as for example, carboxymethylcellulose, alignates, gelatin, polyvinylpyrrolidone, sucrose, and acacia; (c) humectants, as for example, glycerol; (d) disintegrating agents, as for example, agar, calcium carbonate, potato or tapioca starch, alginic acid, certain complex silicates, and sodium carbonate; (e) solution retarders, as for example paraffin; (f) absorption accelerators, as for example, quaternary ammonium compounds; (g) wetting agents, as for example, cetyl alcohol and glycerol monostearate; (h) adsorbents, as for example, kaolin and bentonite; and (i) lubricants, as for example, talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, or mixtures thereof. In the case of capsules, tablets, and pills, the dosage forms may also comprise buffering agents.

[0331] Solid compositions of a similar type may also be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugar, as well as high molecular weight polyethyleneglycols, and the like.

[0332] Solid dosage forms such as tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells, such as enteric coatings and others well-known in the art. They may contain opacifying agents, and can also be of such composition that they release the active compound or compounds in a certain part of the intestinal tract in a delayed manner. Examples of embedding compositions which can be used are polymeric substances and waxes. The active compounds can also be in micro-encapsulated form, if appropriate, with one or more of the above-mentioned excipients.

[0333] Liquid dosage forms for oral administration include pharmaceutically acceptable emulsions, solutions, suspensions, syrups, and elixirs. In addition to the active compounds, the liquid dosage forms may contain inert diluents commonly used in the art, such as water or other solvents, solubilizing agents and emulsifiers, as for example, ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propyleneglycol, 1,3-butyleneglycol, dimethylformamide, oils, in particular, cottonseed oil, groundnut oil, corn germ oil, olive oil, castor oil and sesame oil, glycerol, tetrahydrofurfuryl alcohol, polyethyleneglycols and fatty acid esters of sorbitan or mixtures of these substances, and the like.

[0334] Besides such inert diluents, the composition can also include adjuvants, such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, and perfuming agents.

[0335] Suspensions, in addition to the active compounds, may contain suspending agents, as for example, ethoxylated isostearyl alcohols, polyoxyethylene sorbitol and sorbitan esters, microcrystalline cellulose, aluminum metahydroxide, bentonite, agar-agar and tragacanth, or mixtures of these substances, and the like.

[0336] Compositions for rectal administrations are preferably suppositories which can be prepared by mixing the compounds of the present invention with suitable non-irritating excipients or carriers such as cocoa butter, polyethyleneglycol, or a suppository wax, which are solid at ordinary temperatures but liquid at body temperature and therefore, melt in the rectum or vaginal cavity and release the active component.

[0337] The amount of invention compound to be utilized to prevent and treat thrombotic disorders is that amount which is effective to prevent or treat the condition without causing unacceptable side effects. Such effective amounts will be in the range of about 0.1 to about 2,000 mg per day. For a normal human adult having a body weight of about 70 kilograms, a dosage in the range of about 0.01 to about 10 mg per kilogram of body weight per day is preferable. However, the specific dosage used can vary. For example, the dosage can depended on a numbers of factors including the requirements of the patient, the severity of the condition being treated, and the pharmacological activity of the compound being used. The determination of optimum dosages for a particular patient is well-known to those skilled in the art.

[0338] When the composition is administered orally, a larger quantity of the active agent will typically be required to produce the same effect as caused with a smaller quantity given parenterally.

[0339] The compounds of the present invention may also be used as anti-coagulants in vitro or ex vivo as in the case of contact activation with foreign thrombogenic surfaces such as is found in tubing used in extracorporeal shunts. The compounds of the invention may also be used to coat the surface of such thrombogenic conduits. To this end, the compounds of the invention can be prepared as lyophilized powders, redissolved in isotonic saline or similar diluent, and added in an amount sufficient to maintain blood in an anticoagulated state.

[0340] Preparation of Compounds of the Invention

[0341] The present invention contains compounds that can be synthesized in a number of ways familiar to one skilled in organic synthesis. The compounds outlined herein can be synthesized according to the methods described below, along with methods typically utilized by a synthetic chemist, and combinations or variations of those methods which are generally known to one skilled in the art of synthetic chemistry. The synthetic route of compounds in the present invention is not limited to the methods outlined below. It is assumed one skilled in the art will be able to use the schemes outlined below to synthesize compounds claimed in this invention. Individual compounds may require manipulation of the conditions in order to accommodate various functional groups. A variety of protecting groups generally known to one skilled in the art may be required. The appropriate use and choice of protecting groups is well-known by one skilled in the art, and is not limited to the specific examples below. It is also to be understood that such groups not only serve to protect chemically reactive sites, but also to enhance solubility or otherwise change physical properties. A good general reference for protecting group preparation and deprotection is Greene, Theodora, Protective Groups in Organic Synthesis; Wiley: N.Y., USA, 1991. Purification, if necessary, can be accomplished on a silica gel column eluted with the appropriate organic solvent system. Also, reverse phase HPLC may be employed if a compound does not elute from silica gel.

[0342] Further, in regards to Schemes 1,1a, 2, 2a, 2b, 2c, 3, 3a, 4, 5, and 6, a number of general reactions such as reductions, etc. are not shown in detail but can be done by methods understood by one skilled in the art. General transformations are well-reviewed in Larock, Richard. Comprehensive Organic Transformations; Wsiley: N.Y., USA, 1999, and the series “Compendium of Organic Synthetic Methods” published by Wiley-Interscience. In general, the starting materials are obtained from commercial sources unless otherwise indicated.

[0343] Compounds of the invention can be prepared using the synthetic routes outlined in Schemes 1,1a; 2, 2a, 2b, 2c, 3, 3a, 4, 5, and 6. The routes are useful for a wide variety of starting materials with variable X1 and X2 groups, provided the appropriate protecting group is utilized if necessary. The schemes are also employed for both racemic mixtures and enantiomerically pure compounds.

[0344] The method as disclosed in Scheme 1 includes reacting an amino acid having Formula III with a reagent capable of forming a protecting group on the amino group of an amino acid to form a compound with Formula IV. In Scheme 1, P1 is a protecting group and X1 and X2 are the same as defined above for Formula I. The carboxylic acid of Formula IV is then activated by a coupling reagent, such as BOP, HATU, EEDQ, or CDI for example, and reacted with a haloaniline or a haloaminoheterocycle, for example, to form a halide with Formula V, where Y1 is a halogen and M is as defined above. The compound with Formula V is then subjected to a coupling reaction with a compound having Q to give a compound of Formula VI. The protecting group is then removed from compound VI and the resulting compound reacted with an isocyanate having A to from the compound with Formula I.

[0345] A specific example of a useful method for preparing compounds of Formula I is outlined in Scheme 1a. The synthetic route starts by protecting an amino acid with di-tert-butyl dicarbonate in tetrahydrofuran with 2M NaOH as the base. The Boc-protected amino acid VII is then combined with EEDQ, triethylamine and an appropriate bromoaniline or bromoaminoheterocycle (H2N-M-Br) in a suitable solvent, such as chloroform for example, and heated to reflux to produce VIII. The resulting bromide is then typically subjected to metal catalyzed coupling, such as Suzuki coupling for example, with a boronic acid derivatized compound having Q, although other coupling conditions may be used. The resulting compound is then deprotected with 33% trifluoroacetic acid in dichloromethane and then reacted with an isocyanate with triethylamine in tetrahydrofuran to produce a compound with Formula I. This route is useful for compounds containing a biaryl M-Q moiety, such as a biphenyl group where Q is substituted with a tert-butylsulfonamide (tBuNHSO2) for example. The tert-butyl group could then be removed using standard methods of amine deprotection, such as TFA in dichloromethane for example, to afford the free amine.

[0346] Another method of making the compounds having Formula I is provided in Scheme 2. Scheme 2 is useful for synthesizing a wide variety of M-Q groups. The chemistry is similar to Scheme 1, except that the second step introduces an aniline or aminoheterocycle that includes both the M and Q moieties, instead of a haloaniline or haloaminoaniline, and thus eliminating the coupling step to add the moiety Q. The method as disclosed in Scheme 2 includes reacting an amino acid having Formula X with a reagent capable of forming a protecting group on the amino group of an amino acid to form a compound with Formula XI. In Scheme 2, P1 is a protecting group and X1 and X2 are the same as defined above for Formula I. The carboxylic acid XI is then activated by a coupling reagent, such as BOP, HATU, EEDQ, or CDI for example, and reacted with an aniline or an aminoheterocyclenhaving a formula H2N-M-Q, for example, to form a compound with Formula XII. The protecting group is then removed from compound XII and the resulting compound reacted with an isocyanate having A to from the compound having Formula I.

[0347] A specific example of a useful method for preparing compounds of Formula I is outlined in Scheme 2a. The synthetic route starts by protecting an amino acid XIII with di-tert-butyl dicarbonate in tetrahydrofuran with 2M NaOH as the base. The Boc-protected amino acid XIV is then combined with EEDQ, triethylamine and an appropriate aniline or aminoheterocycle in a suitable solvent, such as chloroform for example, and heated to reflux to produce XV. Compound XV is then deprotected with 33% trifluoroacetic acid in dichloromethane and then reacted with an appropriate A-isocyanate with triethylamine in tetrahydrofuran to produce compounds of Formula I. In cases where X1 and X2 of compound XV form an hydroxymethyl substituted cyclopropyl moiety, TMSI in dichloromethane can be used to deprotect the amino group. This route is also useful for compounds containing a biaryl M-Q moiety, such as a biphenyl group where Q is substituted with a tert-butylsulfonamide (tBuNHSO2) for example. The tert-butyl group could then be removed using standard methods of amine deprotection, such as TFA in dichloromethane for example, to afford the free amine.

[0348] The moiety H2N-M-Q as disclosed in Schemes 2 and 2a can be prepared as outlined in Schemes 2b and 2c. As shown in Scheme 2b the moiety H2N-M-Q can be prepared by contacting the compound XVI with a compound having Q to produce the H2N-M-Q moiety XVII. This reaction can be carried out by combining compound XVI, copper iodide, trans-cyclohexylamine, K3PO4, and Q-H in the presence of a suitable solvent, such as dioxane for example, under refluxing conditions.

[0349] As shown in Scheme 2c the moiety H2N-M-Q can be prepared by contacting the nitro compound XVIII with a compound having Q to produce the O2N-M-Q moiety XIX followed by the reduction of XIX to produce the H2N-M-Q moiety XVII. An example of the preparation of moiety XII involves combining the compound XVIII with a compound having Q in the presence of a suitable solvent, such as propanol, under refluxing conditions. The resulting intermediate, XIX, is then reduced with a suitable reducing agent, such as Raney nickel for example, in a suitable solvent, such as tetrahydrofuran for example, in the presence of hydrogen gas.

[0350] Another method of making the compounds having Formula I is provided in Scheme 3 where X1, X2, M, Q, and A are as described above for compounds of Formula I. Scheme 3 is useful for synthesizing compounds of Formula I where R2 is other than hydrogen. The synthetic route starts by reacting a compound of Formula XVII, prepared according to Schemes 2b or 2c, with an appropriate bromoacetyl chloride of the Formula XX to form a compound of Formula XXI. The amide of Formula XXI is then reacted with an amine of Formula XXII, where R2 is as described above for Formula I to form a compound of Formula XXIII. The compound of Formula XXIII is then reacted with an isocyanate having A to form a compound of Formula I.

[0351] A specific example of a useful method for preparing compounds of Formula I where R2 is other than hydrogen is outlined in Scheme 3a. The synthetic route starts by reacting a compound of Formula XVII, prepared according to Schemes 2b or 2c, with an appropriate bromoacetyl chloride of the Formula XXIV in the presence of a suitable base, such as triethylamine for example, and a suitable solvent, such as dichloromethane for example, to form a compound of Formula XXV. The amide of Formula XXV is then reacted with an amine of Formula XXVI, where R2 is as described above for Formula I, in the presence if a base, such as diisopropylethylamine for example, and a suitable solvent, such as dichloromethane for example, followed by quenching of the reaction with a suitable quenching agent, such as benzaldehyde polystyrene resin for example, to form a compound of Formula XXVII. The compound of Formula XXVII is then reacted with an isocyanate having A, such as 4-chlorophenyl isocyanate for example, in the presence of a suitable base, such as triethylamine for example, and a suitable solvent, such as dichloromethane for example, followed by quenching of the reaction with a suitable quenching agent, such as tris-amine polystyrene resin for example, to form a compound of Formula I.

[0352] Another method of making the compounds having Formula I is provided in Scheme 4 where P1 and P2 are independent protecting groups and X1, X2, M, Q, and A are as described above for compounds of Formula I. Scheme 4 is useful for synthesizing compounds of Formula I where X1 and X2 form a hydroxymethyl substituted cyclopropyl ring. The synthetic route starts with the ring opening of a compound of Formula XXVIII (prepared according to the methods disclosed in K. Burgess et al. J.Org. Chem., 1992, 57, 5931; and D. R. Morton et al. J.Org. Chem., 1978, 57, 2101), with an appropriate base in a suitable solvent to form a compound of Formula XXIX. Suitable bases include hydroxides of the alkaline earth metals such as lithium hydroxide, for example. Suitable solvents include tetrahydrofuran, for example. The reaction can be carried out using lithium hydroxide monohydrate in a 1 to 1 mixture of THEF and water, for example. The hydroxy groups present in the compound of Formula XXIX are then protected using a suitable protecting agent, such as tert-butyldimethylsilyl chloride (TBS-Cl) for example, in the presence of a base, such as imidazole for example. The resulting bis-silylation product is then selectively deprotected to afford the compound of Formula XXX. Selective deprotection can be carried out using a variety of methods known to those of skill in the art including the use of potassium carbonate in a 3 to 1 mixture of methanol and THF for example. The carboxylic acid of Formula XXX is then activated by a coupling reagent, such as BOP, HATU, EEDQ, or CDI for example, and reacted with an amine of Formula XXXI, prepared according to Schemes 2b or 2c, to form a compound of Formula XXXII. The compound of Formula XXXII is then deprotected using a variety of methods known to those of skill in the art including the use of iodotrimethylsilane (TMS-I) in a dichloromethane. Deprotection is followed by reaction with an isocyanate having A, such as 4-chlorophenyl isocyanate for example, in the presence of a suitable solvent, such as THF for example, and a base, such as triethylamine for example, to afford the compound of Formula I.

[0353] Another method of making the compounds having Formula I is provided in Scheme 5 where P1 and P2 are independent protecting groups and X1, X2, M, Q, and A are as described above for compounds of Formula I. Scheme 5 is useful for synthesizing compounds of Formula I where X1 and X2 form a hydroxymethyl substituted cyclopropyl ring. The synthetic route starts with selective protection of a compound of Formula XXXIII (prepared according to Michael C. Pirrung, Stevens E. Dunlap, Uwe P. Trinks. Helv. Chimica. Acta., 1989, 72, 1301-1310). In this step the alcohol hydroxy is selectively protected using a suitable protecting agent, such as acetic anhydride for example, in the presence of a base, such as pyridine for example. The carboxylic acid of Formula XXXIV is then activated by a coupling reagent, such as BOP, HATU, EEDQ, or CDI for example, and reacted with an amine of Formula XXXV, prepared according to Schemes 2b or 2c, to form a compound of Formula XXXVI. The amino moiety of Formula XXXVI is then selectively deprotected using a variety of methods known to those of skill in the art including the use of iodotrimethylsilane (TMS-I) in dichloromethane. Deprotection of the amine is followed by reaction with an isocyanate having A, such as 4-chlorophenyl isocyanate for example, in the presence of a suitable solvent, such as THF for example, and a base, such as triethylamine for example, to afford the compound of Formula XXXVII. The alcohol hydroxy of a compound of FormulaXXXVII is then selectively deprotected using a variety of methods known to those of skill in the art including the use of potassium trimethylsilanolate in a THF to afford a compound of Formula I.

[0354] Another method of making the compounds having Formula I is provided in Scheme 6 where P1, P2 and P3 are independent protecting groups. Scheme 6 is useful for synthesizing compounds of Formula I where X1 and X2 form a substituted nitrogen containing heterocyclic ring such as a pyrrolidine ring substituted at the 1 position for example. The synthetic route starts with reaction of a compound of Formula XXXVIII (prepared according to the methods disclosed in C. Balsamini, E. Duranti, L. Mariani, A. Salvatori, G. Spadoni. Synthesis 1990, 779-781, and O. Mamoun, H. Benhaoua, R. Danion-Bougot, D. Danion. Synth. Comm., 1995, 25, 1295), where P2 is any suitable carboxylic acid protecting group such as that which would form an alkyl ester, with acid in a suitable solvent to form a compound of Formula XXXIX. Suitable acids and solvents for the preparation of compounds of Formula XXXIX include mineral acids, such as hydrochloric acid for example, and nonpolar solvents, such as diethyl ether for example. The amino group of compounds of Formula XXXIX is then reacted with a reagent capable of forming a protecting group, P1, on the amino moiety in a suitable solvent to form a compound with Formula XL. Useful reagents for protecting an amino acid include di-tert-butyl dicarbonate. The heterocycle nitrogen is then reacted with a reagent capable of forming a protecting group, P3, in a suitable solvent to form a compound with Formula XLI. Useful reagents for protecting the heterocycle nitrogen include carbobenzyloxychloride for example. The compound of Formula XLI is then reacted with a base to selectively deprotect the carboxylic acid moiety to afford a free acid of Formula XLII. The reaction can be carried out using hydroxides of the alkaline earth metals such as lithium hydroxide, for example in a suitable nonpolar solvent such as tetrahydrofuran, for example. The carboxylic acid of Formula XLII is then activated by a coupling reagent, such as BOP, HATU, EEDQ, or CDI for example, and reacted with an amine of Formula XLIII, prepared according to Schemes 2b or 2c, to form a compound of Formula XLIV. The compound of Formula XLIV is then selectively deprotected using standard methods of amine deprotection, such as TFA in chloroform for example, to afford the free amine of Formula XLV. The compound of Formula XLV is then reacted with an isocyanate having A, such as 4-chlorophenyl isocyanate for example, in the presence of a suitable solvent, such as THF for example, and a base, such as triethylamine for example, to afford a compound of Formula I. The protecting group for the heterocycle nitrogen may be removed using standard methods for deprotection of an amine which are known to those of skill in the art or the nitrogen may remain protected.

[0355] Not all compounds of Formula I falling into a given class may be compatible with some of the reaction conditions described. Such restrictions are readily apparent to those skilled in the art of organic synthesis, and alternative methods must then be used.

[0356] To further assist in understanding the present invention, the following non-limiting examples of such factor Xa inhibitory compounds are provided. The following examples, of course, should not be construed as specifically limiting the present invention, variations presently known or later developed, which would be within the purview of one skilled in the art and considered to fall within the scope of the present invention as described herein. Preferred synthetic routes for intermediates involved in the synthesis as well as the resulting anti-thrombotic compounds of the present invention follow.

[0468] Biological Assays

[0469] The invention compounds have demonstrated factor Xa inhibitory activity in the standard assays commonly employed by those skilled in the art.

[0470] a. Determination of Factor Xa IC50

[0471] The ability of compounds to act as inhibitors of human factor Xa catalytic activity was assessed by determination of that concentration of test substance that inhibited by 50% (IC50) the ability of human factor Xa to cleave the fluorogenic substrate F-S2765 (N-α-Z-D-Arg-Gly-Arg-pNA HCl, California Peptide Research). Inhibitory amounts of compounds of the invention include those with IC50 values of 1 to 500 nM for example. The IC50 was determined at 3 pM and/or 30 pM concentrations of human factor Xa (Enzyme Research Laboratories). These concentrations were achieved by diluting a stock solution of human factor Xa in the appropriate amount of buffer containing 10 mM HEPES, 150 mM NaCl, and 0.1% BSA at pH 7.4 (HBSA buffer). Accordingly, 73 μL of the factor Xa/buffer solution was added to 2.5 μL of DMSO-reconstituted compound and incubated for 55 minutes at room temperature. After warming to 37° C. for am additional 5 minutes, 50 μL of rewarmed substrate was added and the IC50 determined by monitoring the increase in absorbance at 390 nm excitation/460 nm emission (455 nm cutoff) in a fluorometric plate reader or 30 minutes. Results of the IC50 at 3 pM and 30 pM enzyme concentrations are provided in Table 1.

[0472] b. Determination of Prothrombin Time (PT)

[0473] The prothrombin time (PT) is a measure of extrinsic and common pathway factors. In this assays, human tissue thromboplastin is added to human plasma which activates pathway factors, including factor X activation to factor Xa, leading to clot formation. Significant inhibition of factor Xa, by a small molecule inhibitor, will reduce the conversion of prothrombin to thrombin and thereby increase the time to clot formation in this assay. The value 2 X PT is the concentration of the inhibitor required to increase the clotting time by 2-fold. These values are also presented in Table 1.

[0474] Given the data presented in Table 1, compounds of the present invention act as inhibitors of Factor Xa. Accordingly, the compounds of the present invention are useful in pharmaceutical formulations for preventing and treating thrombotic disorders. Such disorders include venous thrombosis, deep vein thrombosis, thrombophlebitis, arterialembolism, coronary and cerebral arterial thrombosis, cerebral embolism, kidney embolism, pulmonary embolism, first or recurrent myocardial infarction, unstable angina, cerebral infarction, stroke, and atherosclerosis.
