• they show factor Xa-inhibiting properties and can therefore be used to combat and prevent thromboembolic diseases such as thrombosis, myocardial infarction, atherosclerosis,
• the compounds of the formula I according to the invention can furthermore be inhibitors of the coagulation factors factor VIIa, factor IXa and thrombin of the blood coagulation cascade.
• Aromatic amidine derivatives having an antithrombotic effect are known, for example, from EP 0540 051 B1, WO 98/28269, WO 00/71508, WO 00/71511, WO

• the antithrombotic and anticoagulant effect of the compounds according to the invention is attributed to the inhibiting action against the activated coagulation protease, known by the name of factor Xa, or to the inhibition of other activated serine proteases, such as factor VIa, factor IXa or thrombin.
• Factor Xa is one of the proteases involved in the complex process of blood clotting. Factor Xa catalyzes the conversion of prothrombin into thrombin. Thrombin splits fibrinogen into fibrin monomers, which contribute to thrombus formation after cross-linking. Activation of thrombin can lead to the occurrence of thromboembolic disorders. However, inhibition of thrombin may inhibit fibrin formation involved in thrombus formation. The measurement of the inhibition of thrombin can be carried out, for example, according to the method of GF Cousins et al. in Circulation 1996, 94, 1705-1712. Inhibition of factor Xa can thus prevent thrombin from being formed.
• the compounds of the formula I according to the invention and their salts intervene in the blood clotting process by inhibiting the factor Xa and thus inhibit the formation of thrombi.
• the inhibition of the factor Xa by the compounds according to the invention and the measurement of the anticoagulant and antithrombotic activity can be determined by conventional in vitro or in vivo methods.
• a suitable method is described e.g. by J. Hauptmann et al. in Thrombosis and Haemostasis 1B 0, 63, 220-223.
• the measurement of inhibition of factor Xa may be e.g. according to the method of T. Hara et al. in Thromb. Haemostas. 1994, 71, 314-319.
• the coagulation factor VIIa after binding to tissue factor, initiates the extrinsic part of the coagulation cascade and contributes to the activation of factor X to factor Xa. Inhibition of factor VIIa thus prevents the formation of factor Xa and thus subsequent thrombin formation.
• the inhibition of the factor VIIa by the compounds according to the invention and the measurement of the anticoagulant and antithrombotic activity can be determined by conventional in vitro or in vivo methods.
• a common method for measuring the inhibition of factor VIIa is e.g. by H.F. Ronning et al. in Thrombosis Research 1996, 84, 73-81.
• the coagulation factor IXa is generated in the intrinsic coagulation cascade and is also due to the activation of factor X to factor Xa involved. Inhibition of factor IXa may thus otherwise prevent factor Xa from being formed.
• the inhibition of factor IXa by the compounds according to the invention and the measurement of the anticoagulant and antithrombotic activity can be determined by conventional in vitro or in vivo methods. A suitable method is described, for example, by J. Chang et al. in Journal of Biological Chemistry 1998, 273, 12089-12094.
