Replacement of the P4 morpholin-3-one moiety in a selective factor Xa inhibitor rivaroxaban by 2-ethoxycarbonylpiperidine resulted in a dual factor Xa/thrombin inhibitor 24, possessing a Ki of 62 ± 18 nM for factor Xa and a Ki of 353 ± 75 nM for thrombin. Presented rationalization of dual activity provides a good starting point for “designing in” thrombin inhibitory activity to potent factor Xa inhibitor rivaroxaban.
将选择性因子Xa抑制剂利伐沙班中的P4吗啉-3-酮部分替换为2-乙氧基羰基哌啶,得到了一种双重因子Xa/凝血酶抑制剂24,其对因子Xa的Ki值为62 ± 18 nM,对凝血酶的Ki值为353 ± 75 nM。提出的双重活性合理化为“设计”凝血酶抑制活性到强效因子Xa抑制剂利伐沙班提供了良好的起点。
