Various compounds were synthesized by combining three components at positions P1, P1' and P2'. Of these, N-(trans-4-aminomethylcyclohexanecarbonyl)-Tyr(O-2-bromobenzyloxycarbonyl)-octylamide inhibited plasmin selectively with IC50 values of 0.80 and 0.23 μM towards S-2251 and fibrin, respectively. THis compound also inhibited plasma kallikrein, urokinase, thrombin and trypsin with IC50 values of 10, >50, >50 and 1.6 μM, rspectively.
通过在 P1、P1' 和 P2' 位置结合三种成分合成了多种化合物。其中,N-(trans-4-氨甲基环己烷羧酰基)-酪氨酸(O-2-溴苄氧羧基)-辛酸酰胺对纤溶酶的选择性抑制效应,S-2251 和纤维蛋白的 IC50 值分别为 0.80 和 0.23 μM。该化合物还分别以 10、>50、>50 和 1.6 μM 的 IC50 值抑制了血浆激肽释放酶、尿激酶、凝血酶和胰蛋白酶。
