compounds was designed, synthesized and evaluated as cholinesterase inhibitors. The biological assay experiments showed that most of the compounds displayed a clearly selective inhibition for butyrylcholinesterase (BChE), while a weak or no effect towards acetylcholinesterase (AChE) was detected. Among these benzofuran derivatives, compound 16 exhibited the highest BChE inhibition with an IC50 value
设计,合成和评估了一系列2-苯基苯并呋喃化合物作为胆碱酯酶抑制剂。生物学测定实验表明,大多数化合物对丁酰胆碱酯酶(BChE)表现出明显的选择性抑制作用,而对乙酰胆碱酯酶(AChE)的作用却微弱或没有。在这些苯并呋喃衍生物中,化合物16表现出最高的BChE抑制作用,IC50值为30.3μM。通过动力学分析确定该化合物为混合型抑制剂。此外,分子动力学模拟显示化合物16与BChE的催化阴离子位点(CAS)和外围阴离子位点(PAS)都结合,并且显示出最佳的相互作用能值,与我们的实验数据一致。
