4-b]indoles (11-14), and 4,7,8,9-tetrahydro-1H-pyrrolo[2,3-d]azocines (15-18), synthesized through an efficient 6-->8 membered ring expansion procedure, were investigated for their acetylcholinesterase (AChE) inhibitory activities. Most of the compounds acted as AChE inhibitors in vitro, with IC(50) values ranging from 5 to 40 microM. The most potent compounds 11 and 15, both as racemic mixtures, proved selective
环状四氢偶氮cine碱的一系列酯衍生物,即2,3,6,11-四氢-1H-偶氮基[4,5-b]吲哚(5-10),2,3,6,7-四氢-1H-偶氮基[5,4-b]吲哚(11-14)和4,7,8,9-四氢-1H-吡咯并[2,3-d]偶氮星(15-18),是通过有效的6->研究了8元环扩环程序的乙酰胆碱酯酶(AChE)抑制活性。大多数化合物在体外起AChE抑制剂的作用,IC(50)值范围从5到40 microM。最有效的化合物11和15均是外消旋混合物,被证明对AChE具有选择性,相对于约1的丁酰胆碱酯酶(BuChE)表现出选择性。15个和20个以上。结构活性研究强调,除其他因素外,亲脂性是调节AChE抑制能力的一种特性,如pIC(50)和实验性1-辛醇/水分配系数(logP)之间的合理抛物线关系所示,该系数描述了所研究化合物的主要行为(r(2)= 0.665)。使用来自加州鱼雷的AChE的X射线
