A new class of indolotacrine hybrids including cyclopenta- and cyclohexa-indolotacrine derivatives was designed, synthesized, and assessed as acetylcholinesterase inhibitors (AChEIs). Some of the designed derivatives indicated a good inhibitory effect against acetylcholinesterase (AChE). Among them, cyclopenta-indolotacrine hybrids showed a slightly better anti-AChE activity than cyclohexa-indolotacrine
设计、合成并评估了一类新的吲哚他林杂化物,包括环五和环六-吲哚他林衍生物,并将其作为乙酰胆碱酯酶抑制剂 (AChEI) 进行评估。一些设计的衍生物对乙酰胆碱酯酶 (AChE) 具有良好的抑制作用。其中,cyclopenta-indolotacrine hybrids 的抗 AChE 活性略好于 cyclohexa-indolotacrine hybrids。化合物 5-amino-4-(4-chlorophenyl)-2-(1H-indol-3-yl)-4,6,7,8-tetrahydrocyclopenta[b]pyrano[3,2-e]pyridine-3-carbonitrile ( 8g ) 包括 4-氯苯基和环戊烷环显示出最好的 AChE 抑制活性,IC 50值为 0.4 µM。动力学研究表明,化合物8g充当竞争性抑制剂。根据分子对接结果,它同时占据了乙酰胆碱酯酶的催化阴离子位点
