is in particular amidino. The invention further provides particular benzothiophene compounds. Compounds of the invention may be useful as inhibitors of Factor IXa and in the therapy of cardiovascular conditions and diseases, e.g. thrombosis.
FIXa is a serine protease enzyme involved in the intrinsic pathway of the coagulation cascade. The upstream intervention of the coagulation cascade in selectively inhibiting FIXa would leave hemostasis Intact via the extrinsic pathway, leading to an optimum combination of efficacy and safety with low incidence of bleeding. We have identified 2-amindinobenzothiophene template as a lead scaffold for FIXa inhibiton based on its homology with urokinase plasminogen activator (uPA). Subsequent SAR work oil the template revealed a number of highly potent FIXa inhibitors, though with moderate selectivity against FXa. X-ray Study with one of the analogues demonstrated active site binding interaction with the induced opening of the S1 beta pocket and a secondary binding at the S2-S4 sites, which is ill direct contrast with the previous finding.

[EN] Heterocyclic compounds of the formula (I) are provided: wherein ring A, ring B, R1, R2, R3, R4, Y, m, n and q are as defined herein. R1 is in particular amidino. The invention further provides particular benzothiophene compounds. Compounds of the invention may be useful as inhibitors of Factor IXa and in the therapy of cardiovascular conditions and diseases, e.g. thrombosis. [FR] La présente invention concerne des composés de formule (I) : le cycle A, le cycle B, R1, R2, R3, R4, Y, m, n et q étant tels que définis dans le présent document. R1 est plus particulièrement amidino. La présente invention concerne également des composés particuliers de benzothiophène. Les composés de l'invention peuvent être utiles en tant qu'inhibiteurs du facteur IXa ainsi que dans le traitement de troubles et maladies cardiovasculaires, p. ex. la thrombose.
