The present invention is concerned with new compounds, and particularly those having a fused bicyclic ring substituted with an amidine moiety. These compounds are each potent inhibitors of Factor D of the alternate pathway of complement, C1s of the classical pathway of complement, Factors Xa, XIIa, VIIa and thrombin of the coagulation pathway, plasmin in the fibrinolytic pathway, and kallikrein and high molecular weight kininogen in the inflammatory pathways. These proteases, which have serine in their active site, are called serine proteases and they are pivotal to most of the processes of inflammation and coagulation. In fact, these various systems are interactive with one another and it is difficult to activate one pathway without it influencing the others.
本发明涉及新化合物,特别是那些具有被取代的酰胺基团的融合双环环的化合物。这些化合物分别是替代途径的因子D、经典途径的C1s、凝血途径的因子Xa、XIIa、VIIa和凝血酶、纤溶途径的纤溶酶、以及炎症途径的激肽酶和高分子量激肽原的强效抑制剂。这些蛋白酶,在其活性位点中含有丝氨酸,被称为丝氨酸蛋白酶,它们对大多数炎症和凝血过程至关重要。事实上,这些各种系统彼此之间相互作用,很难激活其中一个途径而不影响其他途径。
