Description: SUBSTITUTED (AMINOIMINOMETHYL OR AMINOMETHYL)BENZOHETEROARYL COMPOUNDS FIELD OF THE INVENTION This invention is directed to substituted (aminoiminomethyl or aminomethyl)benzoheteroaryl compounds that inhibit Factor Xa, pharmaceutical compositions comprising these compounds and use of the compounds for inhibiting Factor Xa or otherwise treating a physiological condition in a patient that may be ameliorated by administering these compounds to the patient. BACKGROUND OF THE INVENTION Factor Xa is the penultimate enzyme in the coagulation cascade. Both free Factor Xa and Factor Xa assembled in the prothrombinase complex (Factor Xa, Factor Va, calcium and phospholipid) are inhibited by compounds of formula I. Factor Xa inhibition is obtained by direct complex formation between the inhibitor and the enzyme and is therefore independent of the plasma co-factor antithrombin III. Effective Factor Xa inhibition is achieved by administering the compounds either by oral administration, continuous intravenous infusion, bolus intravenous administration or any other parenteral route such that it achieves the desired effect of preventing the Factor Xa induced formation of thrombin from prothrombin. Anticoagulant therapy is indicated for the treatment and prophylaxis of a variety of thrombotic conditions of both the venous and arterial vasculature. In the arterial system, abnormal thrombus formation is primarily associated with arteries of the coronary, cerebral and peripheral vasculature. The diseases associated with thrombotic occlusion of these vessels principally include acute myocardial infarction (AMI). unstable angina, thromboembolism, acute vessel closure associated with thrombolytic therapy and percutaneous transluminal coronary angioplasty (PTCA). transient ischemic attacks, stroke, intermittent claudication and bypass grafting of the coronary (CABG) or peripheral arteries. Chronic anticoagulant therapy may also be beneficial in preventing the vessel luminal narrowing (restenosis) that often occurs following PTCA and CABG, and in the maintenance of vascular access patency in long-term hemodialysis patients. With respect to the venous vasculature, pathologic thrombus formation frequently occurs in the veins of the lower extremities following abdominal, knee and hip surgery (deep vein thrombosis, DVT). DVT further predisposes the patient to a higher risk of pulmonary thromboembolism. A systemic. disseminated intravascular coagulopathy (DIC) commonly occurs in both vascular systems during septic shock, certain viral infections and cancer. This condition is characterized by a rapid consumption of coagulation factors and their plasma inhibitors resulting in the formation of life-threatening clots throughout the microvasculature of several organ systems. Accumulated experimental evidence has also reflected that prothrombin activation is only one of the biological activities of Factor Xa. EPR-1 (effector cell protease receptor- 1, recognizing Factor Xa), is believed to mediate several of the vascular wall interactions by Factor Xa. It has been shown to be expressed on human umbilical vein endothelial cells, rat smooth muscle cells and platelets(CR McKenzie, et al., Arterioscler Thromb Vase Biol ]6 1285-91 (1996); also F Bono, et al., J Cell Physiol 172 36-43 (1997), AC Nicholson, et al., J Biol Chem 27128407-13 (1996), J.M. Herbert, et al., J Clin Invest 101 993-1000 (1998)). This protease-receptor interaction could mediate not only prothrombinase-catalyzed thrombin generation, but also diverse cellular functions such as cell proliferation, release of PDGF and DNA syntheses. The mitogenic effect of Factor Xa has been reported to be dependent on Factor Xa enzymatic activity (F Bono, et al., J Cell Physiol 172 36-43 (1997), J.M. Herbert, et al., J Clin Invest 101 993-1000 (1998)). TAP for example inhibited the mitogenesis of human and rat cultured vascular smooth muscle cells (F Bono, et al., J Cell Physiol 172 36-43 (1997)). In a study of the rabbit carotid artery air-drying injury model, increased EPR-1 expression was detected after vascular injury. Animals treated with the specific Factor Xa inhibitor, DX-9065a, exhibited less neointimal proliferation. The important regulatory role of Factor Xa in the coagulation process coupled with its mitogenic effects points to Factor Xa's involvement in the formation of thrombin at the luminal surface of the vessel wall and contribution to the atherothrombotic process and abnormal proliferation of vascular cells resulting in restenosis or angiogenesis. In view of the physiological conditions discussed above related to Factor Xa, inhibitors of Factor Xa would be useful in treating those conditions and others that would be ameliorated by a Factor Xa inhibitor.

It is to be understood that this invention covers all appropriate combinations of the particular and preferred groupings referred to herein. Compounds of formula I may be prepared by the application or adaptation of known methods, by which is meant methods used heretofore or described in the literature, or by methods according to the invention described herein. One aspect of this invention involves the syntheses of variously substituted indole, benzofuran and benzothiophene heterocycles. These syntheses are achieved, for example, by functionalization of specific precursors followed by ring synthesis or by derivatization of a preformed ring system. There are numerous approaches to the synthesis and functionalization of the aforementioned heterocycles in the chemical literature (For reviews, see (a) Katritzky, A.R.; Rees, C.W.; Scriven, E.F.V. Eds. Comprehensive Heterocyclic Chemstry II, Vol 2, 119, 607. Elsevier Science 1996 and references therein, (b) Ketcha, D.M. Prog. Heterocycl. Chem. 1997, 9, 97 and references therein, (c) Hughes, D. L. Org. Prep. Proced. Int. 1993, 25, 607). A particularly useful preparative method according to the invention is outlined in Scheme 1. Bromo-indoles can be metalated using sodium hydride or other strong base at or around room temperature followed by treatment (at lower temperature, typically below 0 °C) with an alkyl lithium reagent. Suitable solvents for this method include THF or diethyl ether, either alone or as mixtures with additives such as HMPA, TMEDA or DABCO. The resulting nucleophile is then reacted with a variety of appropriately functional ized/substituted and/or protected electrophiles, for example, such as aldehydes, ketones, alkyl halides, oxiranes, aziridines, ,β-unsaturated carbonyls or ,β-unsaturated esters (Scheme 1) to provide indoles substituted with a variety of functionalized/substituted and/or protected side chains, i.e., wherein Q 1 is - NR 8 P', -OP 1 , -C(0)(H or alkyl), -C(0)-OP' or -SP 1 , wherein P 1 is hydrogen or a protecting group as defined herein. (For representative examples see Moyer, M.P.; Shiurba, J.F.; Rapaport, H. J. Org. Chem., 1986, 51, 5106). Scheme 1 Alternatively, as shown in Scheme 2, bromo-indoles are reacted with terminal olefins (Q'L lb H, wherein Q' is as defined herein and L lb is an alkenylene having at least a terminal double bond), terminal acetylenes (Q'L'Η, wherein Q' is as defined herein and L la is an alkynylene having at least a terminal triple bond), or metalated derivatives thereof (particularly zinc tin and boron), under palladium or nickel catalysis (for examples see J. Tsuji, Palladium Reagents and Catalysts, J. Wiley Publications, 1996. Also Harrington, P.J.; Hegedus, L.S. J. Org. Chem., 1984, 49, 2657), with or without a base, to produce vinyl or acetylenic substituted indoles. The choice of catalyst depends on the substrate employed but is most commonly tetrakistriphenylphosphine palladium, bis(triphenylphosphine)palladium chloride, 1,1 '- bis(diphenylphosphino)ferrocene / bis-dibenzylideneacetone palladium or 1,2 bis-(diphenylphosphino)- ethane / bis(acetonitrile)dichloropalladium. In certain cases, addition of a copper (I) salt as co-catalyst is also required (Rossi, R.; Caφita, A.; Bellina, F. Org. Prep. Proced. Int. 1995, 27, 127). These coupling reactions are performed in various solvents, including toluene, THF, DME, DMSO, DMF, dimethylacetamide and HMPA, at about 20 to about 150 °C. X" = H, Zn, Sn, B Scheme 2 The indole side chains incoφorated as described above, can contain, or be converted to, a variety of functional groups (using one or more steps) including amines, alcohols, aldehydes, ketones, carboxylic acids, esters, olefins, amides, imides, urethanes, carbamates, sulfonamides, sulfones, sulfoxides and sulfides. These interconversions employ standard synthetic methods described in the chemical literature (For example, see Larock, CL. Comprehensive Organic Transformations, VCH Publishers 1989 and Greene, T.W.; Wuts, P.G.M. Protective Groups in Organic Synthesis, John Wiley Publications 1991). In particular, an alcohol in the indole side chain is converted, for example, to the corresponding amine by a sequence (Scheme 3) involving treatment with toluenesulfonyl chloride / DMAP and a base such as triethylamine or diisopropylethylamine in a solvent such as dichloromethane, DMF or pyridine at about room temperature. Alternatively, the alcohol is treated with NBS / Ph 3 P, NCS / Ph 3 P, I 2 / Ph 3 P / imidazole, CBr 4 / Ph 3 P to provide the corresponding alkyl halide (For a review see Castro, B.R. Org. React., 1983, 29, 1). The product is then reacted with sodium azide in a solvent such as DMF, dimethyl acetamide, DMPU or ethanol at about 20 to about 80 °C. The resulting azide is then reduced with a reagent such as triphenylphosphine / water in THF or boron trifluoride etherate / 1,3-propane-dithiol in a solvent such as dichloromethane to the corresponding amine. or BF 3 / HSCH 2 CH 2 CH 2 SH R"' is H or CN Scheme 3 An amino moiety can also be introduced into the indole side chain (Scheme 4) by conversion of an appropriate side chain alkene double bond (L lbb is an alkenylene having at least a double bond at the terminal end thereof distal to its attachment to the indole moiety), first to an alcohol, using a hydroboration oxidation sequence, (For examples see (a) Beletskaya, I; Pelter, A. Tetrahedron, 1997, 53, 4957 and references therein, (b) Brown, H.C; Kramer, G.W.; Levy, M.B.; Midland, M.M., Organic Synthesis via Boranes, Wiley Interscience, N.Y. 1973.), then oxidation of the alcohol to the corresponding ketone using any of a number of common oxidation reagents such as Swern's reagent. (For a review, see Hudlicky, T. Oxidations in Organic Chemistry, ACS Publications 1990) and finally reductive amination of the ketone (Abdel-Magid, A.F.; Maryanoff, C. A. Reductions in Organic Synthesis, ACS Symp. Ser., 641, p201, ACS Publications 1996) with an appropriate amine and a reducing agent such as sodium cyanoborohydride or sodium triacetoxyborohydride in a solvent such as methanol, THF, acetonitrile, HMPA, or water either alone or as cosolvents. In certain cases, the amine moiety may be part of the indole side chain, in which case, a heterocyclyl can be formed. R is as defined herein Scheme 4 Another convenient method for introduction of an amino moiety into the side chain involves treatment of a side chain carboxylic acid with diphenylphosphoryl azide and a base such as triethylamine, diisopropylamine in a solvent such as dichloromethane or THF toluene or benzene usually at about 0 °C to about room temperature. (For a review, see Banthrope, The Chemistry of the Azido Group, S. Patai Ed. Wiley Interscience N.Y. 1971 ). Subsequent thermolysis of the resulting acyl azide at about room temperature to about 140 °C in the presence of an alcohol such as t-butanol, benzyl alcohol or allyl alcohol provides the corresponding carbamate which can be cleaved to the amine using standard protecting group chemistry. Thermolysis of the acyl azide in the absence of an alcohol produces the corresponding isocyanate which may be subsequently reacted with a variety of amines to provide urethanes (for a modification which also provides a convenient preparation of secondary amines see Pfister, J.R.; Wymann, W.E. Synthesis, 1983, 38). Alternatively, a urethane may be incoφorated by reaction of a side chain amino moiety with an appropriate isocyanate. According to Scheme 5, a ketone may also be incorporated into the side chain by hydroboration of an appropriate alkyne (L iaa is an alkynylene having at least a triple bond at the terminal end thereof distal to its attachment to the indole moiety) with catechol borane in a solvent such as THF at about room temperature to about 67 °C, followed by oxidative cleavage of the resulting product with hydrogen peroxide in the presence of a base such as sodium hydroxide. Scheme 5 An imide moiety may be incoφorated by reaction of a side chain alcohol with a preformed, N- unsubstituted-imide using Mitsunobu's reagent (Mitsunobu. O., Synthesis, 1981, 1, an imide, so formed, can also be converted to the corresponding amine by treatment with hydrazine in a solvent such as ethanol). Alternatively, the imide group may be introduced by acylation of a side chain amide with an acid chloride (or an activated ester ) in the presence of a base such as sodium hydride. An amide linkage may be introduced into the indole side chain by reaction of an amine (incoφorated using a method such as described above) with a carboxylic acid. Suitable conditions for effecting this transformation involve activation of the acid with a reagent such as thionyl chloride, isopropyl chloroformate, oxalylchloride / DMF, TBTU, DCC, DICC / HOBT, CDI, BOP, EEDQ or PyBroP (For reviews see (a) Blackburn, C; Kates, S. A. Methods Enzymol. 1997, 289, 175. (b) Bodanszky, M.; Trost, B.M. Principles of Peptide Synthesis 2nd Ed., Springer Verlag, N.Y. 1993) usually in the presence of a base such as triethylamine, diisopropylethylamine and / or DMAP in a solvent such as dichloromethane, DMF, dimethylacetamide or DMPU at about or above room temperature. The reverse orientation of the amide unit may be prepared by reaction of an indole side chain containing an acid moiety with an amine. An acid moiety may be formed in the side chain by oxidation of a side chain alcohol, first to the aldehyde, then oxidation of the aldehyde to the corresponding carboxylic acid. A particularly suitable reagent for this transformation is sodium chlorate (Lidgren, B.O.; Hilsson, T. Acta. Chem. Scand. 1973, 58, 238). Alternatively, an aldehyde may be generated by oxidation of an olefin using osmium tetroxide with a co- catalyst such as sodium periodate in a solvent such as THF / water or t-butanol / water. A carboxylic acid may also be obtained by hydrolysis of the corresponding ester using standard protecting group methodology. A sulfonamide linkage may be introduced into the side chain by reaction of a side chain amino functionality with a sulfonyl chloride in the presence of a base such as pyridine, triethylamine, diisopropylethylamine or sodium hydroxide in a solvent such as dichloromethane, pyridine, DMF or an alcohol such as ethanol or isopropanol. The reverse orientation of the sulfonamide linkage may be produced by the method of Liskamp (Moree, W. J.; Van der Marel, G.A.; Liskamp, R.J. J. Org. Chem. 1995, 60, 1995.) from a side chain thioacetate. The thioacetate moiety may be prepared by displacement of a halide or sulfonate with sodium thioacetate in a solvent such as DMF, DMPU, HMPA or DMSO. A sulfide linkage may be incoφorated into the side chain by saponification of the thioacetate functional group followed by alkylation of the resulting thiol with an appropriate alkyl halide, or sulfonate(such as tosylate, triflate or mesylate). Alternatively, the sulfide linkage may be incoφorated by direct reaction of a side chain alkyl chloride, bromide, iodide, tosylate or mesylate with a thiolate ion in a solvent such as benzene, DMF, DMPU, HMPA or DMSO. In certain cases, a sulfide can be formed from an appropriate disulfide and a side chain alcohol in the presence of tributylphosphine in a solvent such as THF. The sulfoxide and sulfone linkages may be introduced by mild oxidation of the sulfides with a reagent such as m-chloroperbenzoic acid in dichloromethane chloroform or benzene at about or below room temperature. An ether linkage (for a review see Comprehensive Organic Chemistry Vol 1, p 799, Ed. Barton, D.; Ollis, W.D., Pergamon Press, 1979) may be prepared from a side chain alcohol and an alkyl halide, sulfonate or unsaturated ketone derivative and a base such as sodium hydride potassium hydride in a solvent such as DMF DMSO THF DMPU or HMPA. Alternatively, an ether linkage may be obtained using a side chain alkyl halide, sulfonate or ,β-unsaturated ketone and an appropriate alcohol under the same conditions. Another method of ether formation involves formation of a thiono-ester from a side chain ester or lactone by reaction with a thionating reagent, such as Lawesson's reagent (For a review see Cava, M. P.; Levinson, M. I. Tetrahedron (1985), 41(22), 5061-87), followed by reduction of the thiono group with a hydride reducing agent such as tributyltin hydride, usually in the presence of a free radical initiator such as AIBN. Introduction of a nitrile at C-3 of the indole ring system (Scheme 6) may be accomplished by first formylation at C-3 using a reagent combination such as phosphorous oxychloride in DMF, at or above room temperature, followed by conversion of the resulting aldehyde to the corresponding oxime with hydroxylamine hydrochloride in a solvent such as toluene or xylene in the presence of a catalyst such as toluene sulfonic acid and a desiccant such as magnesium sulfate according to the method of Ganbao and Palomo (Ganbao, I.; Palomo, C. Syn. Commun. 1983, 13, 219. For alternatives to this procedure see Wang, E-C; Lin, G-J. Tetrahedron Lett. 1998, 39, 4047 and references therein) Heating the oxime with these reagents at about 80 °C to about 150 °C then results in dehydration to form the corresponding nitrile. In certain favorable cases, the formylation conditions described above also result in conversion of a side chain alcohol into the corresponding alkyl chloride. I 2 I Scheme 6 Introduction of the C-3 nitrile, as described above, may be carried out either before or after derivatization of the side chain(s) at other positions on the indole ring depending on the nature of the functionality present. Another embodiment of this invention involves the use of a benzothiophene in place of an indole scaffold. A variety of methods can be applied to the synthesis of benzothiophenes (for examples see Katritzky, A.R.; Rees, C.W.; Scriven, E.F.V. Eds. Comprehensive Heterocyclic Chemistry II, Vol. 2, p 607, Elsevier Science 1996 and references therein). A particularly useful protocol with reference to the current invention is outlined in Scheme 7. Starting from an appropriate bromo-thiophenol, alkylation of the thiol with bromo-acetaldehyde diethyl acetal in the presence of a base such as NaH in a solvent such as DMF, THF, TBTU, DMSO or HMPA followed by cyclization with an acid such as polyphosphoric acid provides the corresponding bromo-benzothiophene (for examples see Titus, R.L.; Choi, M.; Hutt, M.P. J. Heterocycl. Chem. 1967, 4, 651. and Clark, P.D.; Kirk, A.; Yee, J.G.K. J. Org. Chem. 1995, 60, 1936). This structure may be manipulated using many of the same procedures used to install and functionalize the side chain of the indole scaffold described above. Introduction of a nitrile at C-3 of the benzothiophene ring may be effected by treatment with bromine in a solvent such as acetic acid or chloroform. The resulting 3-bromo- benzothiophene can then be converted to the 3-cyano- derivative using zinc cyanide and a palladium catalyst, preferably tetrakis(triphenylphosphine) palladium(o) in DMF at about 70°C to about 90 °C. CuCN Scheme 7 In certain cases, it is convenient to prepare a specifically substituted heteroaryl scaffold by direct ring synthesis. A particularly suitable ring synthesis protocol employs an adaptation of the method of Yamanaka (Sakamoto, K.; Nagano, T.; Kondo, Y.; Yamanaka, H. Synthesis, 1990, 215). In this approach, an appropriately substituted aniline, thiophenol or phenol is first brominated or more preferably, iodinated ortho to the nitrogen / sulfur / oxygen substituent on the ring (Scheme 8). Suitable reagents for effecting this transformation include bromine in the presence of either acid (such as acetic acid) or a base (such as sodium acetate, sodium carbonate, triethylamine or pyridine), iodine or iodine monochloride in the presence of a soft Lewis acid such as silver sulfate or a base such as calcium carbonate, morpholine, dimethylamine or pyridine. Suitable solvents for this process include water, methanol, ethanol or dichloromethane at about or below room temperature. Addition of the acrylonitrile functionality to the ring heteroatom can be effected following the procedures of Scotti and Frazza (Scotti, F.; Frazza, E.J. J. Org. Chem., 1964, 29, 1800) W = 0, S, NR .CN Base cι J Scheme 8 A particular embodiment of the current invention employs indoles / benzothiophenes / benzofurans substituted with a side chain which contains (aryl or heteroaryl)-substituted aryl or heteroaryl appendages. These latter structural motifs can be prepared by cross coupling (Scheme 9) of an appropriately substituted (heteroaryl or aryl)halide or triflate with a (heteroaryl or aryl)aryl organometallic (most commonly zinc, boron, magnesium and tin derivatives) under catalysis by Pd(o) or Ni(o) employing conditions described above for derivatization of 5-bromo-indole.

X M X = Br, I, 0 3 SR M = Zn, B, Mg, Sn Ar 1 and Ar 2 are appropriately substituted aryl or heteroaryl Scheme 9 Aryl and heteroaryl substituted heterocycles can also be prepared by direct ring synthesis. A wide variety of methods and conditions for this kind of process are known in the chemical literature ( for examples see(a) Katritzky, A.R.; Rees, C.W.; Scriven, E.F.V. Eds. Comprehensive Heterocyclic Chemstry II, Elsevier Science 1996). In another embodiment of this invention the indole / benzothiophene / benzofuran side chain is substituted with a substituted aryl group. One particularly useful aryl substitution comprises of a 1,1 -dimethyl alkyl chain further substituted with a heteroatom, a heteroatom cluster (such as a diol or amino- alcohol) or a heteroaryl (such as imidazole). These systems can be prepared from 2-(4-furan-2-yl-phenyl)-2- methyl-propionic acid methyl ester or 2-(4-bromo-phenyl)-2-methyl-propionic acid methyl ester a shown in scheme 10. J is ring system substitent 1 DIBALH 2 Swern 3 Wittig 4 RuCI 3 (cat) / Nal0 4 Scheme 10 Treatment of 2-(4-furan-2-yl-phenyl)-2-methyl-propionic acid methyl ester with methyl lithium in the presence of lithium hexamethyldisilazide at about or below room temperature and reaction of the resulting enolate with TMS chloride provides the corresponding silylenol ether. Reaction of this intermediate with 1 eq of bromine at low temperature (typically at about -78 °C) furnishes the α- bromoketone. This compound can be treated with formamide at elevated temperatures (from about 50 °C to about 180 °C) to provide imidazole. Alternatively, the bromo ketone can be reacted with sodium azide followed by reduction with sodium borohydride to provide the amino alcohol. After, protection of the amino alcohol as a BOC derivative of the amine and a TBS ether of the alcohol, the furan ring can be oxidatively cleaved to provide the benzoic acid derivative. This unit can then be attached to the heteroaryl scaffold as described above. Reduction of 2-(4-furan-2-yl-phenyl)-2-methyl-propionic acid methyl ester with lithium aluminum hydride in a solvent such as THF followed by oxidation of the resulting primary alcohol to the corresponding aldehyde and Wittig or Horner-Emmons olefin reactions provides access to chain extended alkenes (For a review see Cadogan, J.I.G. Organophosphorus Reagents in Organic Synthesis, Academic Press, 1979). In the case where R = Ome, this system can be hydrolyzed to the corresponding aldehyde with dilute HC1 then oxidized to the carboxylic acid as previously described. Amide formation followed by reduction with a reagent such as borane in THF provides a series of amines. Subsequent oxidative cleavage of the furan ring as described above provides a useful functional group for attachment to the heterocyclic scaffold. Additionally, treatment of 2-(4-bromo-phenyl)-2-methyl-propionic acid methyl ester with diisobutylaluminum hydride at -78 °C in dichloromethane followed by Swern oxidation of the resulting alcohol and Wittig reaction on the aldehyde provides the one carbon chain extended olefin. Osmylation of this species, followed by protection of the resulting diol as an acetonide allows oxidation of the furan ring to the carboxylic acid which provides an attachment point for coupling to the heteroaryl scaffold. It is often useful to introduce conformational constraints into a linker to optimize the availability of a bioactive conformer. These constraining groups can also interact favorably with a target protein providing an additional advantage. An example of the synthesis of a system which can produce such effects is shown in Scheme 11. Two carbon chain extension of the bromo indole by adaptation of the method of Migata (Kosugi, M; Negishi, Y.; Kameyama, M.; Migata, T.; Bull, Chem. Soc. Jpn., 1985, 58, 3383; Agnelli, F., Sulikowski, G.A. Tetrahedron Letts 1998, 39, 8807) then treatment of the resulting ester with TMS triflate and triethylamine in ether at 0 °C provides the silyl ketene acetal. Reaction of this species with an amine acetal in dichloromethane in the presence of TMS triflate as a catalyst, generates the substituted ,β-amino ester (for representative examples see Okano, K.; Morimoto, T.; Sekiya, M. J. Chem Soc, Chem. Commun., 1984, 883 and Colvin, E.W.; McGarry, D.G.; Nugent, M.J. Tetrahedron, 1988, 44, 4157). Acylation of the amino group then provides access to a variety of amide substituted scaffolds. 1. TMSOTf / Et 3 N 2. TMSOTf / R 1 = Me or TMS R 1 OCHR"N(SiMe 3 ) 2 3. MeOH R" is hydrogen or alkyl Scheme 11 Transformation of the C-3 nitrile into the corresponding amidine can be carried out employing a number of standard procedures, (for examples see Judkins, B.D.; Allen, D.G.; Cook, T.A.; Evans, B.; Sardharwala, T.E. Syn. Comm. 1996, 26, 4351 and references therein). Treatment of the nitrile (Scheme 12) with HCl in a solvent such as methanol or ethanol at about or above room temperature provides the imidate ester intermediate which can then be converted to the amidine by treatment with ammonia or an alkylamine in a solvent such as methanol or ethanol. Alternatively, reaction of the nitrile with hydrogen sulfide in a solvent such as pyridine, followed by alkylation of the resulting thioamide with an alkylating agent such as methyl iodide in a solvent such as acetone at a temperature at or above room temperature and treatment of this product with ammonia or ammonium acetate in a solvent such as methanol at about or above room temperature provides the final amidine. Scheme 12 An amidine can also be prepared by addition of hydroxylamine to the nitrile to form the corresponding N-hydroxyamidine followed by acylation and hydrogenolysis ofthe N-0 bond using hydrogen / acetic acid / acetic anhydride in the presence of a catalyst such as palladium on carbon. For certain transformations of the side chain, it may be necessary or preferable to protect the indole nitrogen as an inert derivative (Protective Groups in Organic Synthesis, T.W. Greene and P.G.M. Wuts; John Wiley Publications 1991). A particularly suitable derivative for this puφose is the t-butyloxy-carbamate. This can be prepared by reaction of the appropriate indole with di-t-butyldicarbonate in THF or dichloromethane in the presence of a base such as DMAP / triethylamine or diisopropylethylamine at about or above room temperature. The nitrogen of the amidine functional group can be protected using essentially the same conditions described above for the indole nitrogen. Cleavage of these BOC derivatives can be accomplished by treatment with TFA in dichloromethane or with HCl in ethyl acetate. It will be apparent to those skilled in the art that certain compounds of formula I can exhibit isomerism, for example geometrical isomerism, e.g., E or Z isomerism, and optical isomerism, e.g., R or S configurations. Geometrical isomers include the cis and trans forms of compounds of the invention having alkenyl moieties. Individual geometrical isomers and stereoisomers within formula I, and their mixtures, are within the scope of the invention. Such isomers can be separated from their mixtures, by the application or adaptation of known methods, for example chromatographic techniques and recrystallization techniques, or they are separately prepared from the appropriate isomers of their intermediates, for example by the application or adaptation of methods described herein. The compounds of the present invention are useful in the form of the free base or acid or in the form of a pharmaceutically acceptable salt thereof. All forms are within the scope of the invention. Where the compound of the present invention is substituted with a basic moiety, acid addition salts are formed and are simply a more convenient form for use; and in practice, use of the salt form inherently amounts to use of the free base form. The acids which can be used to prepare the acid addition salts include preferably those which produce, when combined with the free base, pharmaceutically acceptable salts, that is, salts whose anions are non-toxic to the patient in pharmaceutical doses of the salts, so that the beneficial inhibitory effects on Factor Xa inherent in the free base are not vitiated by side effects ascribable to the anions. Although pharmaceutically acceptable salts of said basic compounds are preferred, all acid addition salts are useful as sources of the free base form even if the particular salt, per se, is desired only as an intermediate product as, for example, when the salt is formed only for purposes of purification, and identification, or when it is used as intermediate in preparing a pharmaceutically acceptable salt by ion exchange procedures. Pharmaceutically acceptable salts within the scope of the invention are those derived from the following acids: mineral acids such as hydrochloric acid, sulfuric acid, phosphoric acid and sulfamic acid; and organic acids such as acetic acid, citric acid, lactic acid, tartaric acid, malonic acid, methanesufonic acid, ethanesulfonic acid, benzenesulfonic acid, p-toluenesulfonic acid, cyclohexylsulfamic acid, quinic acid, and the like. The corresponding acid addition salts comprise the following: hydrohalides, e.g. hydrochloride and hydrobromide, sulfate, phosphate, nitrate, sulfamate, acetate, citrate, lactate, tartarate, malonate, oxalate, salicylate, propionate, succinate, fumarate, maleate, methylene-bis-β-hydroxy- naphthoates, gentisates, mesylates, isethionates, di-p-toluoyltartrates, methanesulfonate, ethanesulfonate, benzenesulfonate, p-toluenesulfonate, cyclohexylsulfamate and quinate, respectively. According to a further feature of the invention, acid addition salts of the compounds of this invention are prepared by reaction of the free base with the appropriate acid, by the application or adaptation of known methods. For example, the acid addition salts of the compounds of this invention are prepared either by dissolving the free base in aqueous or aqueous-alcohol solution or other suitable solvents containing the appropriate acid and isolating the salt by evaporating the solution, or by reacting the free base and acid in an organic solvent, in which case the salt separates directly or can be obtained by concentration of the solution. The acid addition salts of the compounds of this invention can be regenerated from the salts by the application or adaptation of known methods. For example, parent compounds of the invention can be regenerated from their acid addition salts by treatment with an alkali, e.g. aqueous sodium bicarbonate solution or aqueous ammonia solution. Where the compound of the invention is substituted with an acidic moiety, base addition salts may be formed and are simply a more convenient form for use; and in practice, use of the salt form inherently amounts to use of the free acid form. The bases which can be used to prepare the base addition salts include preferably those which produce, when combined with the free acid, pharmaceutically acceptable salts, that is, salts whose cations are non-toxic to the animal organism in pharmaceutical doses of the salts, so that the beneficial inhibitory effects on Factor Xa inherent in the free acid are not vitiated by side effects ascribable to the cations. Pharmaceutically acceptable salts, including for example alkali and alkaline earth metal salts, within the scope of the invention are those derived from the following bases: sodium hydride, sodium hydroxide, potassium hydroxide, calcium hydroxide, aluminum hydroxide, lithium hydroxide, magnesium hydroxide, zinc hydroxide, ammonia, ethylenediamine, N-methyl-glucamine, lysine, arginine, ornithine, choline, N,N'-dibenzylethylenediamine, chloroprocaine, diethanolamine, procaine, N-benzylphenethylamine, diethylamine, piperazine, tris(hydroxymethyl)-aminomethane, tetramethylarnmonium hydroxide, and the like. Metal salts of compounds of the present invention may be obtained by contacting a hydride, hydroxide, carbonate or similar reactive compound of the chosen metal in an aqueous or organic solvent with the free acid form of the compound. The aqueous solvent employed may be water or it may be a mixture of water with an organic solvent, preferably an alcohol such as methanol or ethanol, a ketone such as acetone, an aliphatic ether such as tetrahydrofuran, or an ester such as ethyl acetate. Such reactions are normally conducted at ambient temperature but they may, if desired, be conducted with heating. Amine salts of compounds of the present invention may be obtained by contacting an amine in an aqueous or organic solvent with the free acid form of the compound. Suitable aqueous solvents include water and mixtures of water with alcohols such as methanol or ethanol, ethers such as tetrahydrofuran, nitriles such as acetonitrile, or ketones such as acetone. Amino acid salts may be similarly prepared. The the compounds of this invention can be regenerated from the salts by the application or adaptation of known methods. For example, parent compounds of the invention can be regenerated from their base addition salts by treatment with an acid, e.g. hydrochloric acid. Pharmaceutically acceptable salts also include quaternary lower alkyl ammonium salts. The quaternary salts are prepared by the exhaustive alkylation of basic nitrogen atoms in compounds, including nonaromatic and aromatic basic nitrogen atoms, according to the invention, i.e., alkylating the non-bonded pair of electrons of the nitrogen moieties with an alkylating agent such as methylhalide, particularly methyl iodide, or dimethyl sulfate. Quaternarization results in the nitrogen moiety becoming positively charged and having a negative counter ion associated therewith. As will be self-evident to those skilled in the art, some of the compounds of this invention do not form stable salts. However, acid addition salts are most likely to be formed by compounds of this invention having a nitrogen-containing heteroaryl group and/or wherein the compounds contain an amino group as a substituent. Preferable acid addition salts of the compounds of the invention are those wherein there is not an acid labile group. As well as being useful in themselves as active compounds, salts of compounds of the invention are useful for the puφoses of purification of the compounds, for example by exploitation of the solubility differences between the salts and the parent compounds, side products and/or starting materials by techniques well known to those skilled in the art. The starting materials and intermediates are prepared by the application or adaptation of known methods, for example methods as described in the Reference Examples or their obvious chemical equivalents, or by methods according to this invention. The present invention is further exemplified but not limited by the following illustrative examples which illustrate the preparation of the compounds according to the invention. Experimental Section Unless otherwise stated, all starting materials are obtained from commercial suppliers and are used without further purification. Reactions are routinely carried out under an inert atmosphere of nitrogen or argon using anhydrous solvents obtained from Aldrich Chemical Company. Flash column chromatography is performed on Merck silica gel (230-400 mesh) eluting with the specified solvent mixture. Reverse phase HPLC is performed using Dynamax C-18 (60A) columns, eluting with a water / acetonitrile gradient (containing a fixed 0.1% v/v trifluoroacetic acid additive) with UV detection (λ = 220, 254, 294 nM). Η NMR spectra are recorded at a frequency of 300 MHz in the specified deuterated solvent. Chemical shifts are in ppm relative to the resonance frequency of tetramethylsilane δ= 0.00. The following conventions are used throughout to describe NMR spectra: s = singlet, d = doublet, t = triplet, q = quartet, m = multiplet, b = broad. Coupling constants are designated with the symbol J and are measured in Hz. Example la N-(2-[3-Carbamimidoyl-5-indolyl]ethyl)-4-pyrid-3-ylbenzamide. A stream of HCl gas is bubbled through a cooled (0 °C) slurry of N-(2-[3-Cyano-5-indolyl]ethyl)-4-pyrid-3- ylbenzamide (reference example la) in MeOH (10 mL) for seven minutes, after which the reaction is capped and allowed to stir overnight at room temperature. After purging with a stream of nitrogen, the reaction is concentrated, and 15 mL 7N NH 3 in MeOH is added. After stirring overnight, the reaction is purged with nitrogen and concentrated, The residue is chromatographed (3:1 CH 2 C1 2 : 7N NH 3 in MeOH) to afford partially purified product.

The molecules described herein inhibit blood coagulation by virtue of their ability to inhibit the penultimate enzyme in the coagulation cascade, Factor Xa, rather than thrombin. Both free Factor Xa and Factor Xa assembled in the prothrombinase complex (Factor Xa, Factor Va, calcium and phospholipid) are inhibited. Factor Xa inhibition is obtained by direct complex formation between the inhibitor and the enzyme and is therefore independent of the plasma co-factor antithrombin III. Effective Factor Xa inhibition is achieved by administering the compounds either by oral administration, continuous intravenous infusion, bolus intravenous administration or any other parenteral route such that it achieves the desired effect of preventing the Factor Xa induced formation of thrombin from prothrombin. Anticoagulant therapy is indicated for the treatment and prophylaxis of a variety of physiological thrombotic conditions of both the venous and arterial vasculature. In the arterial system, abnormal thrombus formation is primarily associated with arteries of the coronary, cerebral and peripheral vasculature. The diseases associated with thrombotic occlusion of these vessels principally include acute myocardial infarction (AMI), unstable angina, thromboembolism, acute vessel closure associated with thrombolytic therapy and percutaneous transluminal coronary angioplasty (PTCA), transient ischemic attacks, stroke, intermittent claudication and bypass grafting of the coronary (CABG) or peripheral arteries. Chronic anticoagulant therapy may also be beneficial in preventing the vessel luminal narrowing (restenosis) that often occurs following PTCA and CABG, and in the maintenance of vascular access patency in long-term hemodialysis patients. With respect to the venous vasculature, pathologic thrombus formation frequently occurs in the veins of the lower extremities following abdominal, knee and hip surgery (deep vein thrombosis, DVT). DVT further predisposes the patient to a higher risk of pulmonary thromboembolism. A systemic, disseminated intravascular coagulopathy (DIC) commonly occurs in both vascular systems during septic shock, certain viral infections and cancer. This condition is characterized by a rapid consumption of coagulation factors and their plasma inhibitors resulting in the formation of life-threatening thrombin throughout the microvasculature of several organ systems. The indications discussed above include some, but not all, of the possible clinical situations where anticoagulant therapy is warranted. Those experienced in this field are well aware of the circumstances requiring either acute or chronic prophylactic anticoagulant therapy. In addition to their use in anticoagulant therapy, Factor Xa inhibitors may find utility in the treatment or prevention of other diseases in which the generation of thrombin has been implicated as playing a physiologic role. For example, thrombin has been proposed to contribute to the morbidity and mortality of such chronic and degenerative diseases as arthritis, cancer, atherosclerosis and Alzheimer's disease by virtue of its ability to regulate many different cell types through specific cleavage and activation of a cell surface thrombin receptor, mitogenic effects, diverse cellular functions such as cell proliferation, for example, abnormal proliferation of vascular cells resulting in restenosis or angiogenesis, release of PDGF and DNA syntheses. Inhibition of Factor Xa will effectively block thrombin generation and therefore neutralize any physiologic effects of thrombin on various cell types. Accordingly, the invention provides a method of inhibiting Factor Xa comprising contacting a Factor Xa inhibitory amount of a compound of formula I with a composition containing Factor Xa. According to a further feature of the invention there is provided a method of inhibiting the formation of thrombin comprising contacting Factor Xa inhibitory amount of a compound of formula I with a composition containing Factor Xa. According to a further feature of the invention there is provided a method for the treatment of a human or animal patient suffering from, or subject to, conditions which can be ameliorated by the administration of an inhibitor of Factor Xa, for example conditions as hereinbefore described, which comprises the administration to the patient of an effective amount of compound of formula I or a composition containing a compound of formula I. "Effective amount" is meant to describe an amount of compound of the present invention effective in inhibiting Factor Xa and thus producing the desired therapeutic effect. The present invention also includes within its scope pharmaceutical formulations which comprise at least one of the compounds of Formula I in association with a pharmaceutically acceptable carrier or coating. In practice, compounds of the present invention may generally be administered parenterally, intravenously, subcutaneously, intramuscularly, colonically, nasally, intraperitoneally, rectally or orally. The products according to the invention may be presented in forms permitting administration by the most suitable route and the invention also relates to pharmaceutical compositions containing at least one product according to the invention which are suitable for use in human or veterinary medicine. These compositions may be prepared according to the customary methods, using one or more pharmaceutically acceptable adjuvants or excipients. The adjuvants comprise, inter alia, diluents, sterile aqueous media and the various non-toxic organic solvents. The compositions may be presented in the form of tablets, pills, granules, powders, aqueous solutions or suspensions, injectable solutions, elixirs or syrups, and can contain one or more agents chosen from the group comprising sweeteners, flavorings, colorings, and stabilizers in order to obtain pharmaceutically acceptable preparations. The choice of vehicle and the content of active substance in the vehicle are generally determined in accordance with the solubility and chemical properties of the product, the particular mode of administration and the provisions to be observed in pharmaceutical practice. For example, excipients such as lactose, sodium citrate, calcium carbonate, dicalcium phosphate and disintegrating agents such as starch, alginic acids and certain complex silicates combined with lubricants such as magnesium stearate, sodium lauryl sulfate and talc may be used for preparing tablets. To prepare a capsule, it is advantageous to use lactose and high molecular weight polyethylene glycols. When aqueous suspensions are used they can contain emulsifying agents or agents which facilitate suspension. Diluents such as sucrose, ethanol, polyethylene glycol, propylene glycol, glycerol and chloroform or mixtures thereof may also be used. For parenteral administration, emulsions, suspensions or solutions of the products according to the invention in vegetable oil, for example sesame oil, groundnut oil or olive oil, or aqueous-organic solutions such as water and propylene glycol, injectable organic esters such as ethyl oleate, as well as sterile aqueous solutions of the pharmaceutically acceptable salts, are used. The solutions of the salts of the products according to the invention are especially useful for administration by intramuscular or subcutaneous injection. The aqueous solutions, also comprising solutions of the salts in pure distilled water, may be used for intravenous administration with the proviso that their pH is suitably adjusted, that they are judiciously buffered and rendered isotonic with a sufficient quantity of glucose or sodium chloride and that they are sterilized by heating, irradiation or microfiltration. Suitable compositions containing the compounds of the invention may be prepared by conventional means. For example, compounds of the invention may be dissolved or suspended in a suitable carrier for use in a nebulizer or a suspension or solution aerosol, or may be absorbed or adsorbed onto a suitable solid carrier for use in a dry powder inhaler. Solid compositions for rectal administration include suppositories formulated in accordance with known methods and containing at least one compound of formula I. The percentage of active ingredient in the compositions of the invention may be varied, it being necessary that it should constitute a proportion such that a suitable dosage shall be obtained. Obviously, several unit dosage forms may be administered at about the same time. The dose employed will be determined by the physician, and depends upon the desired therapeutic effect, the route of administration and the duration of the treatment, and the condition of the patient. In the adult, the doses are generally from about 0.01 to about 100, preferably about 0.01 to about 10, mg/kg body weight per day by inhalation, from about 0.01 to about 100, preferably 0.1 to 70, more especially 0.5 to 10, mg/kg body weight per day by oral administration, and from about 0.01 to about 50, preferably 0.01 to 10, mg/kg body weight per day by intravenous administration. In each particular case, the doses will be determined in accordance with the factors distinctive to the subject to be treated, such as age, weight, general state of health and other characteristics which can influence the efficacy of the medicinal product. The products according to the invention may be administered as frequently as necessary in order to obtain the desired therapeutic effect. Some patients may respond rapidly to a higher or lower dose and may find much weaker maintenance doses adequate. For other patients, it may be necessary to have long-term treatments at the rate of 1 to 4 doses per day, in accordance with the physiological requirements of each particular patient. Generally, the active product may be administered orally 1 to 4 times per day. For other patients, it will be necessary to prescribe not more than one or two doses per day. The compounds of formula (I) may be used alone or in combination with other diagnostic, cardioprotective agents, direct thrombin inhibitors, anticoagulants, antiplatelet or fibrinolytic agents. Often patients are concurrently treated prior, during and after interventional procedures with agents of these classes either in order to safely perform the interventional procedure or to prevent deleterious effects of thrombus formation. Some examples of classes of agents which may be used in combination with a compound of formula (I) are selected from: anti-coagulants such as Factor Xa inhibitors, Factor Vila inhibitors, warfarin or heparin; synthetic pentasaccharides; anti-platelet agents such as aspirin, piroxicam or ticlopidine; direct thrombin inhibitors (e.g. boroarginine derivatives, hirudin or argatroban (Novastan ® )); fibrinogen receptor antagonists; statins / fibrates; or fibrinolytic agents (thrombolytic agents) such as tissue plasminogen activator, anistreplase (Eminase ® ), urokinase or streptokinase; or combinations thereof. The term cardioprotective agents as used herein, denotes agents that act to protect myocardium during ischemia. These cardioprotective agents include, but are nor limited to, adenosine agonists, β- blockers and Na H exchange inhibitors. Adendosine agonists include those compounds disclosed in Spada et al., US Patent No. 5,364,862 and Spada et al., US Patent No. 5,736,554, the disclosures of which are hereby incoφorated herein by reference. An example of an adenosine agonists is AMP 579 (Rhone- Poulenc Rorer). An example of a Na/H exchange inhibitor is Cariporide (HOE 642). The term anti-coagulant agents as used herein, denotes agents that inhibit blood coagulation. Such agents include warfarin (Coumadin ® ) and heparin. The term anti-platelet agents as used herein, denotes agents that inhibit platelet function such as by inhibiting the aggregation, adhesion or granular secretion of platelets. Such agents include the various known non-steroidal anti-inflammatory drugs (NSAIDS) such as aspirin, ibuprofen, naproxen, sulindac, indomethacin, mefenamate, droxicam, diclofenac, sulfinpyrazone, and piroxicam (Feldane ® ), including pharmaceutically acceptable salts or prodrugs thereof. Other suitable anti-platelet agents include ticlopidine (Ticlid), thromboxane-A2-receptor antagonists and thromboxane-A2-synthetase inhibitors, as well as pharmaceutically acceptable salts or prodrugs thereof. The phrase direct thrombin inhibitors (i.e. Factor Ila inhibitors), as used herein, denotes inhibitors of the serine protease thrombin. By inhibiting thrombin directly, the inhibition of the cleavage of fibrinogen to fibrin, activation of Factor Xllla, activation of platelets, and feedback of thrombin to the coagulation cascade to generate more thrombin, occurs. Such direct inhibitors include boroarginine derivatives and boropeptides, hirudin and argatroban (Novastan ® ), including pharmaceutically acceptable salts and prodrugs thereof. Boroarginine derivatives and boropeptides include N-acetyl and peptide derivatives of boronic acid, such as C-terminal α-aminoboronic acid derivatives of lysine, ornithine, arginine, homoarginine and corresponding isothiouronium analogs thereof.

Such agents include tissue plasminogen activator, anistreplase (Eminase ® ), urokinase or streptokinase, including pharmaceutically acceptable salts or prodrugs thereof. Tissue plasminogen activator (tPA) is commercially available from Genentech Inc., South San Francisco, Calif. The term urokinase, as used herein, is intended to denote both dual and single chain urokinase, the latter also being referred to herein as prourokinase. The compounds described herein may be administered to treat thrombotic complications in a variety of animals such as primates including humans. Inhibition of factor Xa is useful not only in the anticoagulant therapy of individuals having thrombotic conditions but is useful whenever inhibition of blood coagulation is required such as to prevent coagulation of stored whole blood and to prevent coagulation in other biological samples for testing or storage. Thus, any inhibitor of Factor Xa activity can be added to or contacted with any medium containing or suspected of containing Factor Xa and in which it is desired that blood coagulation be inhibited. The compounds of the present invention may be used in combination with any antihypertensive agent or cholesterol or lipid regulating agent, or concurrently with agents used in the treatment of restenosis, atherosclerosis or high blood pressure. Some examples of agents that are useful in combination with a compound according to the invention in the treatment of high blood pressure include compounds of the following classes: beta-blockers, ACE inhibitors, calcium channel antagonists and alpha-receptor antagonists. Some examples of agents that are useful in combination with a compound according to the invention in the treatment of elevated cholesterol levels or disregulated lipid levels include compounds known to be HMGCoA reductase inhibitors, compounds of the fibrate class. It is understood that the present invention includes combinations of compounds of the present invention with one or more of the aforementioned therapeutic class agents Compounds within the scope of the present invention exhibit marked pharmacological activities according to tests described in the literature and below which tests results are believed to correlate to pharmacological activity in humans and other mammals. Enzyme Assays: The ability of the compounds of the present invention to act as inhibitors of Factor Xa, thrombin, trypsin, tissue-plasminogen activator (t-PA), urokinase-plasminogen activator (u-PA), plasmin and activated protein C is evaluated by determining the concentration of inhibitor which resulted in a 50% loss in enzyme activity (IC50) using purified enzymes. All enzyme assays are carried out at room temperature in 96-well microtiter plates using a final enzyme concentration of 1 nM. The concentrations of Factor Xa and thrombin are determined by active site titration and the concentrations of all other enzymes are based on the protein concentration supplied by the manufacturer. Compounds according to the invention are dissolved in DMSO, diluted with their respective buffers and assayed at a maximal final DMSO concentration of 1.25%. Compound dilutions are added to wells containing buffer and enzyme and pre-equilibrated for between 5 and 30 minutes. The enzyme reactions are initiated by the addition of substrate and the color developed from the hydrolysis of the peptide-p-nitroanilide substrates is monitored continuously for 5 minutes at 405 nm on a Vmax microplate reader (Molecular Devices). Under these conditions, less than 10% of the substrate is utilized in all assays. The initial velocities measured are used to calculate the amount of inhibitor which resulted in a 50% reduction of the control velocity (IC 50 ). The apparent Ki values are then determined according to the Cheng- Prusoff equation (IC50 = Ki [1+[S]/Km]) assuming competitive inhibition kinetics. An additional in vitro assay may be used to evaluate the potency of compounds according to the invention in normal human plasma. The activated partial thromboplastin time is a plasma-based clotting assay that relies on the in situ generation of Factor Xa, its assembly into the prothrombinase complex and the subsequent generation of thrombin and fibrin which ultimately yields the formation of a clot as the assay endpoint. This assay is currently used clinically to monitor the ex vivo effects of the commonly used anticoagulant drug heparin as well as direct acting antithrombin agents undergoing clinical evaluation. Therefore, activity in this in vitro assay is considered as a surrogate marker for in vivo anticoagulant activity. Human Plasma Based Clotting Assay: Activated partial thromboplastin clotting times are determined in duplicate on a MLA Electra 800 instrument. A volume of 100 μl of citrated normal human pooled plasma (George King Biomedical) is added to a cuvette containing 100 μl of a compound according to the invention in Tris/NaCl buffer (pH 7.5) and placed in the instrument. Following a 3 minute warming period the instrument automatically adds 100 μl of activated cephaloplastin reagent (Actin, Dade) followed by 100 μl of 0.035 M CaCl2 to initiate the clotting reaction. Clot formation is determined spectrophotometrically and measured in seconds. Compound potency is quantitated as the concentration required to double a control clotting time measured with human plasma in the absence of the compound according to the invention. Compounds according to the invention may also be evaluated for their in vivo antithrombotic efficacy in two well established animal experimental models of acute vascular thrombosis. A rabbit model of jugular vein thrombosis and a rat model of carotid artery thrombosis are used to demonstrate the antithrombotic activity of these compounds in distinct animal model paradigms of human venous thrombosis and arterial thrombosis, respectively. Experimental In Vivo Rabbit Venous Thrombosis Model: This is a well characterized model of fibrin rich venous thrombosis that is validated in the literature and shown to be sensitive to several anticoagulant drugs including heparin (Antithrombotic Effect of Recombinant Truncated Tissue Factor Pathway Inhibitor (TFPI 1-161) in Experimental Venous Thrombosis- a Comparison with Low Molecular Weight Heparin, J. Hoist, B. Lindblad, D. Bergqvist, O. Nordfang, P.B. Ostergaard, J.G.L. Petersen, G. Nielsen and U. Hedner. Thrombosis and Haemostasis, 7J_, 214-219 (1994). The puφose of utilizing this model is to evaluate the ability of compounds to prevent the formation of venous thrombi (clots) in vivo generated at a site of injury and partial stasis in the jugular vein. Male and female New Zealand white rabbits weighing 1.5-2 kg are anesthetized with 35 mg/kg of ketamine and 5 mg/kg xylazine in a volume of 1 mL/kg (i.m.). The right jugular vein is cannulated for infusion of anesthetic (ketamine/xylazine 17/2.5 mg/kg/hr at a rate of approximately 0.5 mL/hr) and administration of test substances. The right carotid artery is cannulated for recording arterial blood pressure and collecting blood samples. Body temperature is maintained at 39°C with a GAYMAR T-PUMP. The left external jugular vein is isolated and all side branches along an exposed 2-3 cm of vessel are tied off. The internal jugular vein is cannulated, just above the bifurcation of the common jugular, and the tip of the cannula is advanced just proximal to the common jugular vein. A 1 cm segment of the vein is isolated with non-traumatic vascular clamps and a relative stenosis is formed by tying a ligature around the vein with an 18G needle just below the distal most clamp. This creates a region of reduced flow and partial stasis at the injury site. The isolated segment is gently rinsed with saline 2-3 times via the cannula in the internal jugular. Thereafter the isolated segment is filled with 0.5 mL of 0.5% polyoxyethylene ether (W-1) for 5 minutes. W-1 is a detergent which disrupts the endothelial cell lining of the segment, thus providing a thrombogenic surface for initiating clot formation. After 5 minutes the W-1 is withdrawn from the segment, and the segment is again gently rinsed with saline 2-3 times. The vascular clamps are then removed, restoring blood flow through this portion of the vessel. Clot formation is allowed to form and grow for 30 minutes after which the vein is cut just below the stenotic ligature and inspected for blood flow (the absence of blood flow is recorded as complete occlusion). The entire isolated segment of vein is then ligated and the formed clot is removed and weighed (wet weight). The effect of test agents on final clot weights is used as the primary end point. Animals are maintained for an additional thirty minutes to obtain a final pharmacodynamic measure of anticoagulation. Drug administration is initiated 15 minutes prior to vascular injury with W-1 and continued through the period of clot formation and maturation. Three blood samples (3 mL ea.) are obtained for evaluation of hemostatic parameters: one just prior to administration of W-1; a second 30 minutes after removal of the vascular clamps and a third at the termination of the experiment. Antithrombotic efficacy is expressed as a reduction in the final clot weight in preparations treated with a compound according to the invention relative to vehicle treated control animals. Experimental In Vivo Rat Arterial Thrombosis Model: The antithrombotic efficacy of Factor Xa inhibitors against platelet-rich arterial thrombosis may be evaluated using a well characterized rat carotid artery FeCl2-induced thrombosis model (Superior Activity of a Thromboxane Receptor Antagonist as Compared with Aspirin in Rat Models of Arterial and Venous Thrombosis, W.A. Schumacher, CL. Heran, T.E. Steinbacher, S. Youssef and M.L. Ogletree. Journal of Cardiovascular Pharmacology, 22, 526-533 (1993); Rat Model of Arterial Thrombosis Induced by Ferric Chloride, K.D. Kurtz, B.W. Main, and G.E. Sandusky. Thrombosis Research, 60, 269-280 (1990); The Effect of Thrombin Inhibition in a Rat Arterial Thrombosis Model, R.J. Broersma, L.W. Kutcher and E.F. Heminger. Thrombosis Research 64, 405-412 (1991). This model is widely used to evaluate the antithrombotic potential of a variety of agents including heparin and the direct acting thrombin inhibitors. Sprague Dawley rats weighing 375-450 g are anesthetized with sodium pentobarbital (50 mg/kg i.p.). Upon reaching an acceptable level of anesthesia, the ventral surface of the neck is shaved and prepared for aseptic surgery. Electrocardiogram electrodes are connected and lead II is monitored throughout the experiment. The right femoral vein and artery are cannulated with PE-50 tubing for administration of a compound according to the invention and for obtaining blood samples and monitoring blood pressure, respectively. A midline incision is made in the ventral surface of the neck. The trachea is exposed and intubated with PE-240 tubing to ensure airway patency. The right carotid artery is isolated and two 4-0 silk sutures are placed around the vessel to facilitate instrumentation. An electromagnetic flow probe (0.95-1 mm lumen) is placed around the vessel to measure blood flow. Distal to the probe a 4x4 mm strip of parafilm is placed under the vessel to isolate it from the surrounding muscle bed. After baseline flow measurements are made, a 2x5 mm strip of filter paper previously saturated in 35% FeCl2 is placed on top of the vessel downstream from the probe for ten minutes and then removed. The FeCl2 is thought to diffuse into the underlying segment of artery and cause deendothelialization resulting in acute thrombus formation. Following application of the FeCl2-soaked filter paper, blood pressure, carotid artery blood flow and heart rate are monitored for an observation period of 60 minutes. Following occlusion of the vessel (defined as the attainment of zero blood flow), or 60 minutes after filter paper application if patency is maintained, the artery is ligated proximal and distal to the area of injury and the vessel is excised. The thrombus is removed and weighed immediately and recorded as the primary end point of the study. Following surgical instrumentation a control blood sample (Bl) is drawn. All blood samples are collected from the arterial catheter and mixed with sodium citrate to prevent clotting. After each blood sample, the catheter is flushed with 0.5 mL of 0.9% saline. A compound according to the invention is administered intravenously (i.v.) starting 5 minutes prior to FeCl2 application. The time between FeCl2 application and the time at which carotid blood flow reached zero is recorded as time to occlusion (TTO). For vessels that did not occlude within 60 minutes, TTO is assigned a value of 60 minutes. Five minutes after application of FeCl2, a second blood sample is drawn (B2). After 10 minutes of FeCl2 exposure, the filter paper is removed from the vessel and the animal is monitored for the remainder of the experiment. Upon reaching zero blood flow blood a third blood sample is drawn (B3) and the clot is removed and weighed. Template bleeding time measurements are performed on the forelimb toe pads at the same time that blood samples are obtained. Coagulation profiles consisting of activated partial thromboplastin time (APTT) and prothrombin time (PT) are performed on all blood samples. In some instances a compound according to the invention may be administered orally. Rats are restrained manually using standard techniques and compounds are administered by intragastric gavage using a 18 gauge curved dosing needle (volume of 5 mL/kg). Fifteen minutes after intragastric dosing, the animal is anesthetized and instrumented as described previously. Experiments are then performed according to the protocol described above. The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof.
