The compounds of formula I can be present as salts, in particular pharmaceutically acceptable salts. If the compounds of formula I have, for example, at least one basic center, they can form acid addition salts. These are formed, for example, with strong inorganic acids, such as mineral acids, for example sulfuric acid, phosphoric acid or a hydrohalic acid, with strong organic carboxylic acids, such as alkanecarboxylic acids of 1 to 4 carbon atoms which are unsubstituted or substituted, for example, by halogen, for example acetic acid, such as saturated or unsaturated dicarboxylic acids, for example oxalic, malonic, succinic, maleic, fumaric, phthalic or terephthalic acid, such as hydroxycarboxylic acids, for example ascorbic, glycolic, lactic, malic, '--taric or citric acid, such as amino 13 WO 00/47563 PCT/US00/01859 acids, (for example aspartic or glutamic acid or lysine or arginine), or benzoic acid, or with organic sulfonic acids, such as (C 1

The compounds of formula I having at least one acid group (for example COOH) can also form salts with bases. Suitable salts with bases are, for example, metal salts, such as alkali metal or alkaline earth metal salts, for example sodium, potassium or magnesium salts, or salts with ammonia or an organic amine, such as morpholine, thiomorpholine, piperidine, pyrrolidine, a mono-, di- or tri-lower alkylamine, for example ethyl-, tert-butyl-, diethyl-, diisopropyl-, triethyl-, tributyl- or dimethyl-propylamine, or a mono-, di- or trihydroxy lower alkylamine, for example mono-, dior triethanolamine. Corresponding internal salts may furthermore be formed. Salts which are unsuitable for pharmaceutical uses but which can be employed, for example, for the isolation or purification of free compounds I or their pharmaceutically acceptable salts, are also included.

Preferred salts of the compounds of formula I include monohydrochloride, hydrogensulfate, methanesulfonate, phosphate or nitrate.

The compounds of the present invention are inhibitors of the activated coagulation serine protease known as Factor Xa and thus are useful for the treatment or prophylaxis of those processes which involve the oroduction and/or action of Factor Xa. Thus, the compounds of the invention are useful in the treatment or prevention of thrombotic events associated with coronary artery and cerebrovascular disease. This includes a number of thrombotic and prothrombotic states in which the coagulation cascade is activated which include, but are not limited to, formation of atherosclerotic plaques, venous or arterial thrombosis, coagulation syndromes, ischemia and angina (stable and unstable), deep vein thrombosis (DVT), disseminated intravascular coagulopathy, Kasabach-Merritt syndrome, pulmonary embolism, myocardial infarction, cerebral infarction, cerebral thrombosis, atrial 20 WO 00/47563 PCT/US00/01859 fibrillation, cerebral embolism, thromboembolic complications of surgery (such as hip replacement, introduction of artificial heart valves and endarterectomy) and peripheral arterial occlusion. The compounds of the invention are also useful as inhibitors of blood coagulation such as during the preparation, storage and fractionation of whole blood.

The present compounds may also be useful in maintaining whole and fractionated blood in the fluid phase such as required for analytical and biological testing.

Examples include, but are not limited to, ex vivo platelet and other cell function studies, bioanalytical procedures and quantitation of blood-containing components.

In addition, the compounds of the present invention may be useful to prevent restenosis following arterial injury induced by endogenous (rupture of an atherosclerotic plaque) or exogenous (invasive cardiological procedure such as vessel wall injury resulting from angioplasty) events.

The compounds of the present invention may also be used as an anticoagulant in extracorpeal blood circuits, such as those necessary in dialysis and surgery (such as coronary artery bypass surgery).

In addition, the compounds of the present invention may be useful for maintaining blood vessel patency in conjunction with vascular surgery including bypass grafting, arterial reconstruction, atherectomy, vascular graft and stent patency, organ, tissue and cell implantation and transplantation.

The compounds of the present invention may be useful for the treatment of heparin-intolerant patients, including those with congenital and acquired antithrcmbin III deficiencies, heparin-induced thrombocytopenia, and those with high levels of polymorphonuclear granulocyte elastase.

The compounds of the present invention may act in a synergistic fashion with one or more of the above agents to prevent reocclusion following a successful thrombolytic therapy and/or reduce the time to reperfusion. The compounds of the present invention may also allow for reduced doses of the thrombolytic agent to be used and therefore minimize potential hemorrhagic side-effects.

The compounds of the present invention may also inhibit other serine proteases, for example, thrombin, Factor VIIa, urokinase-type plasminogen activator (urokinase), tryptase and/or trypsin. As a result, these compounds may additionally be useful as angiogenesis inhibitors in the treatment of cancer, as antiinflammatory agents particularly in the treatment of chronic asthma and in the treatment or prevention of allergic rhinitis, rheumatoid arthritis, inflammatory bowel disease, psoriasis, and conjunctivitis and in the treatment or prevention of pancreatitis.
