-pyran one (4)) and tested them for inhibitory activity against some trypsin-like enzymes, namely trypsin, urokinase, tissue plasminogen activator (t-PA), plasmin, and thrombin, as well as alpha-chymotrypsin and human neutrophil elastase (HNE). The beta-aryl-substituted protio lactone 3 was a potent alternate substrate inhibitor of trypsin and urokinase. The alpha-aryl-substituted iodo lactone 2 was
我们已经合成了四种胍基苯基取代的蛋白质烯醇和碘烯醇内酯(3-(4-胍基苯基)-6-亚甲基四氢-2-吡喃酮(1),3-(4-胍基苯基)-6-(E)-(碘代亚甲基)四氢-2-吡喃一(2),4-(4-胍基苯基)-6-亚甲基四氢-2-吡喃酮+++(3)和4-(4-胍基苯基)-6-(E)-(碘亚甲基)四氢-2-吡喃一(4))并测试它们对某些胰蛋白酶样酶的抑制活性,这些酶包括胰蛋白酶,尿激酶,组织纤溶酶原激活剂(t-PA),纤溶酶和凝血酶,以及α-胰凝乳蛋白酶和人类嗜中性白细胞弹性蛋白酶(HNE)。β-芳基取代的蛋白质内酯3是胰蛋白酶和尿激酶的有效替代底物抑制剂。α-芳基取代的碘内酯2是尿激酶,纤溶酶,t-PA,凝血酶和α-胰凝乳蛋白酶的永久灭活剂,对前两种酶表现出较高的特异性。通常,与α-胰凝乳蛋白酶和HNE相比,这些化合物表现出对胰蛋白酶样酶失活的偏好。同样,在胰蛋白酶样酶类别中,通常具有良好的抑制选择性。
