ylic acid followed by N-substitution, were evaluated as angiotensin converting enzyme (ACE) inhibitors. Among all the new compounds screened (2R,11aS)-10-((4-bromothiophen-2-yl)methyl)-2-hydroxy-2,3-dihydro-1H-benzo[e]pyrrolo[1,2-a][1,4]diazepine-5,11(10H,11aH)dione, 5v (IC50: 0.272 μM) emerged as most active non-carboxylic acid ACE inhibitor with minimal toxicity comparable to clinical drugs Lisinopril
通过基于结构的合理杂交方法设计的一系列新颖的10-取代的2-羟基吡咯并苯并二氮杂5,11-二酮,是通过等渗酸酐与(2 S,4 R)-4-羟基吡咯烷-2-羧酸的环脱水反应合成的,然后N-取代被评估为血管紧张素转化酶(ACE)抑制剂。在所有新化合物中,筛选出(2 R,11 aS)-10-((4-溴噻吩-2-基)甲基)-2-羟基-2,3-二氢-1 H-苯并[ e ]吡咯并[1, 2- a ] [1,4]二氮杂5,11(10 H,11 aH)二酮,5v(IC 50:0.272μM)成为最具活性的非羧酸ACE抑制剂,其毒性可与临床药物利西普利,贝那普利和雷米普利媲美。对接研究中良好的结合特性也支持了实验结果。
