Aeruginosins are a family of naturally occurring oligopeptides sharing a common perhydroindole-2-carboxylic acid (l-Choi) core structure. Many aeruginosins exhibit inhibitory activity against serine proteases including thrombin. Aeruginosin 298-A is a tetrapeptide containing the l-Choi core structure and three other unusual amino acids or their derivatives; it is a thrombin and trypsin inhibitor. As
铜绿素是一族天然的寡肽,共有一个共同的全氢吲哚-2-羧酸(1-Choi)核心结构。许多铜绿素酶对包括凝血酶在内的丝氨酸蛋白酶显示出抑制活性。Aeruginosin 298-A是一种四肽,含有l-Choi核心结构和其他三个不常见的氨基酸或它们的衍生物;它是凝血酶和胰蛋白酶抑制剂。为了从天然产物类似物中找到有效的凝血酶抑制剂,并了解刚性双环氨基酸对凝血酶抑制活性的影响,我们合成了两种铜绿素酶298-A类似物,其中的l-Choi被环氧合取代全氢吲哚-2-羧酸。Choi变体是分别从d-和l-葡萄糖合成的对映异构体。
