The synthesis and angiotensin converting enzyme (ACE) inhibiting activities of quinapril (CI-906, 22), its active diacid (CI-928, 33), and its dimethoxy analogue (CI-925, 25) are reported. These tetrahydro-3-isoquinolinecarboxylic acid derivatives possess equivalent in vitro potency and in vivo efficacy to enalapril. Sulfhydryl analogues with the same structural variation are also highly potent. In
据报道奎纳普利(CI-906,22),其活性二酸(CI-928,33)和其二甲氧基类似物(CI-925,25)的合成和血管紧张素转化酶(ACE)抑制活性。这些四氢-3-异喹啉羧酸衍生物具有与依那普利相当的体外效能和体内功效。具有相同结构变化的巯基类似物也非常有效。相反,四氢-1-异喹啉羧酸和同源异吲哚啉-1-羧酸类似物在两种类型的效力上显示出惊人的差异,巯基类似物基本上是无活性的,而非巯基类似物与脯氨酸原型是等效的。这是第一个证据表明小分子ACE抑制剂的两个主要结构类别可能存在其他结合模式。
