Description: NAPHTHYL-SUBSTITUTED BENZIMIDAZOLE DERIVATIVES AS ANTI-COAGULANTS Field of the Invention The present invention is directed to naphthyl-substituted benzimidazole derivatives and their pharmaceutically acceptable salts, which inhibit certain enzymes in the coagulation cascade, such as factor Xa and factor Ila (thrombin), thereby being useful as anti-coagulants. It also relates to pharmaceutical compositions containing the derivatives or their pharmaceutically acceptable salts, and their methods of use. BACKGROUND OF THE INVENTION Factor Xa is a member of the trypsin-li e serine protease class of enzymes. A one-to-one binding of factors Xa and Va with calcium ions and phospholipid forms the prothrombinase complex which converts prothrombin to factor Ila (thrombin) . Thrombin, in turn, converts fibrinogen to fibrin which polymerizes to form insoluble fibrin. In the coagulation cascade, the prothrombinase complex is the convergent poy t of the intrinsic (surface activated ) and extrinsic (vessel injury-tissue factor) pathways (Biochemistry (1991 ), Vol. 30, p. 10363; and Ce// (1988), Vol. 53, pp. 505-51 8) . The model of the coagulation cascade has been refined further with the discovery of the mode of action of tissue factor pathway inhibitor (TFPl) (Seminars in Hematology ( 1992), Vol. 29, pp. 1 59-1 61 ) . TFPI is a circulating multi-domain serine protease inhibitor with three Kuπitz-like domains which competes with factor Va for free factor Xa. Once formed, the binary complex of factor Xa and TFPI becomes a potent inhibitor of the factor Vila and tissue factor complex. Factor Xa can be activated by two distinct complexes, by tissue factor-factor Vila complex on the "Xa burst" pathway and by the factor IXa-Vllla complex (TENase) of the "sustained Xa" pathway in the coagulation cascade. After vessel injury, the "Xa burst" pathway is activated via tissue factor (TF) . Up regulation of the coagulation cascade occurs via increased factor Xa production via the "sustained Xa" pathway. Down regulation of the coagulation cascade occurs with the formation of the factor Xa-TFPI complex, which not only removes factor Xa but also inhibits further factor formation via the "Xa burst" pathway. Consequently, there is a natural regulation of the coagulation cascade by factor Xa. Published data with the proteins antistasin and tick anti-coagulant peptide (TAP) demonstrate that factor Xa inhibitors are efficacious anti-coagulants (Thrombosis and Haemostasis (1 992) , Vol. 67, pp. 371 -376; and Science ( 1 990), Vol. 248, pp. 593-596) . The active site of factor Xa can be blocked by either a mechanism-based or a tight binding inhibitor (a tight binding inhibitor differs from a mechanism-based inhibitor by the lack of a covalent link between the enzyme and the inhibitor) Two types of mechanism-based inhibitors are known, reversible and irreversible, which are distinguished by ease of hydrolysis of the enzyme-inhibitor link ( Thrombosis Res ( 1 992) , Vol 67, pp. 221 -231 , and Trends Pharmacol. Set ( 1987), Vol. 8, pp. 303-307) A series of guanidino compounds are examples of tight-binding inhibitors (Thrombosis Res ( 1980), Vol 19, pp. 339-349). Arylsulfonyl-arginme-pipeπdinecarboxylic acid derivatives have also been shown to be tight-binding inhibitors of thrombin (Biochem ( 1 984) , Vol. 23, pp. 85-90), as well as a series of arylamidine-containing compounds, including 3-amιdιnophenylaryl derivatives (Thrombosis Res ( 1 983), Vol. 29, pp. 635-642) and bιs(amιdιno)beπzyl cycloketones (Thrombosis Res ( 1 980), Vol 1 7, pp 545-548) Therapeutic utility of these compounds, however, is limited by their poor selectivity for factor Xa Related Disclosures European Published Patent Application 0 540 051 (Nagahara et al ) describes aromatic amidine derivatives which are stated to be capable of showing a strong anticoagulant effect through reversible inhibition of factor Xa. The synthesis of σ,σ'-bιs(amιdιnobenzylιdene)cycloalkanones and σ,σ' bιs(amιdιno- benzyDcycloalkanones is described in Pharmazie ( 1 977), Vol. 32, No 3, pp. 141 -145 These compounds are disclosed as being serine protease inhibitors.

Utility and Administration A. Utility The compounds of the invention are inhibitors of factor Xa and factor Ila and therefore useful as anti-coagulants in treating disease-states characterized by thrombotic activity based on factor Xa's or factor lla's role in the coagulation cascade (see Background of the Invention above). A primary indication for the compounds is prophylaxis for long term risk following myocardial infarction. Additional indications are prophylaxis of deep vein thrombosis (DVT) following orthopedic surgery or prophylaxis of selected patients following a transient ischemic attack. The compounds of the invention may also be useful for indications in which coumadiπ is currently used, such as for DVT or other types of surgical intervention such as coronary artery bypass graft and percutaneous transluminal coronary angioplasty. The compounds are also useful for the treatment of thrombotic complications associated with acute promyeiocytic leukemia, diabetes, multiple myelomas, disseminated intravascular coagulation associated with septic shock, purpura fulminanas associated infection, adult respiratory distress syndrome, unstable angina, and thrombotic complications associated with aortic valve or vascular prosthesis. The compounds are also useful for prophylaxis for thrombotic diseases, in particular in patients who have a high risk of developing such disease. In addition, the compounds of the invention are useful as in vitro diagnostic reagents for inhibiting factor Xa or factor Ila in the coagulation cascade. B. Testing The primary bioassays used to demonstrate the inhibitory effect of the compounds of the invention on factor Xa or factor Ila are simple chromogenic assays involving only serine protease, the compound of the invention to be tested, substrate and buffer (see, e.g., Thrombosis Res. ( 1 979), Vol. 1 6, pp. 245-254) . For example, four tissue human serine proteases can be used in the primary bioassay, free factor Xa, prothrombinase, thrombin (factor Ila) and tissue plasminogen activator (tPA) . The assay for tPA has been successfully used before to demonstrate undesired side effects in the inhibition of the fibnnolytic process (see, e.g. , J. Med Chem. ( 1 993), Vol. 36, pp. 314-319). Another bioassay useful in demonstrating the utility of the compounds of the invention in inhibiting factor Xa demonstrates the potency of the compounds against free factor Xa in citrated plasma. For example, the anticoagulant efficacy of the compounds of the invention will be tested using either the prothrombin time (PT), or activated partial thromboplastin time (aPTT) while selectivity of the compounds is checked with the thrombin clotting time (TCT) assay. Correlation of the K, in the primary enzyme assay with the K, for free factor Xa in citrated plasma will screen against compounds which interact with or are inactivated by other plasma components. Correlation of the K, with the extension of the PT is a necessary in vitro demonstration that potency in the free factor Xa inhibition assay translates into potency in a clinical coagulation assay. In addition, extension of the PT in citrated plasma can be used to measure duration of action in subsequent pharmacodynamic studies. For further information on assays to demonstrate the activity of the compounds of the invention, see R. Lottenberg et at. , Methods in Enzymology ( 1 981 ), Vol. 80, pp. 341 -361 , and H. Ohno et al. , Thrombosis Research (1980), Vol. 19, pp. 579-588. C.
