The molecule of trans-4-aminomethylcyclohexanecarbonylphenylalanine 4-carboxymethylanilide (8), which is a potent and selective inhibitor of plasma kallikrein, can be devided into three parts (P1, P1' and P2'), each of which contains one of the rings. In order to study the role of each part in the manifestation of potent and selective inhibitory activity and the relationship between the structure and inhibitory activities toward plasmin, plasma kallikrein, urokinase and thrombin, each part was substituted with various other moieties to give many kinds of analogs and their inhibitory activities against the above enzymes were examined. Among them, trans-4-aminomethylcyclohexanecarbonyl-O-2-bromobenzyloxycarbonyltyrosine 4-acetylanilide (12) inhibited plasmin and plasma kallikrein with IC50 values of 2.3×10-7 M and 3.7×10-7 M, and Ki values of 1.2×10-7 M and 1.3×10-7 M, respectively.

分子trans-4-氨基甲基环己烷羰基苯丙氨酸4-羧甲基苯甲酰胺(8)是一种有效的选择性血浆激肽释放酶抑制剂,可以分为三个部分(P1,P1'和P2'),每个部分包含一个环。为了研究每个部分在表现强效选择性抑制活性中的作用以及结构与对纤溶酶、血浆激肽释放酶、尿激酶和凝血酶抑制活性之间的关系,每个部分被不同基团取代,生成多种类似物,并检测它们对上述酶的抑制活性。其中,trans-4-氨基甲基环己烷羰基-O-2-溴苄氧羰基酪氨酸4-乙酰苯甲酰胺(12)对纤溶酶和血浆激肽释放酶的IC50值分别为2.3×10-7 M和3.7×10-7 M,Ki值分别为1.2×10-7 M和1.3×10-7 M。
