N alpha-(arylsulfonyl)-L-arginine amide derivatives having carboxamide N-substituents with a carboxyl group was prepared and tested as inhibitors of the clotting activity of thrombin. The most inhibitory compounds were obtained when a carboxyl group was introduced into the carbon next to the amide nitrogen of N alpha-(arylsulfonyl)-L-arginine amide derivatives, e.g., N alpha-(arylsulfonyl)-L-arginyl-N-butyl-
制备了一系列具有羧基羧基酰胺N-取代基的Nα-(芳基磺酰基)-L-精氨酸酰胺衍生物,并测试了它们作为凝血酶凝血活性的抑制剂。当在Nα-(芳基磺酰基)-L-精氨酸酰胺衍生物(例如Nα-(芳基磺酰基)-L-精氨酸-N-丁基)的酰胺氮旁的碳原子中引入羧基时,获得最具抑制性的化合物。 -,N-(甲氧基乙基)-或N-(四氢糠基)甘氨酸和4-烷基-1- [Nα-(芳基磺酰基)-L-精氨酰基] -2-哌啶甲酸,I50为1-3 X 10( -7)M.
