acetylcholinesterase inhibitors (AChEIs). Molecular docking and scoring was utilized for the design of inhibitors. The molecules were synthesized via an easily accessible, convergent synthetic route. Three triazolopyrimidine based compounds showed nanomolar activity towards acetylcholinesterase. Among them, Ethyl 6-fluoro-4-(4-(5-methyl-[1,2,4]triazolo[1,5-a]pyrimidin-7-yl)piperazin-1-yl)quinoline-3-carboxylate (10d)
在本研究中,设计,合成和评估了一系列三唑并嘧啶-喹啉和氰基吡啶-喹啉杂化物,作为乙酰胆碱酯酶抑制剂(AChEI)。分子对接和评分用于抑制剂的设计。分子是通过容易获得的,会聚的合成途径合成的。三种基于三唑并嘧啶的化合物显示出对乙酰胆碱酯酶的纳摩尔活性。其中,乙基6-氟-4-(4-(5-甲基-[1,2,4]三唑并[1,5-a]嘧啶-7-基)哌嗪-1-基)喹啉-3-羧酸酯(10d),强烈抑制AChE,IC 50值为42 nM。此外化合物10d被认为是对丁酰胆碱酯酶(BuChE)具有12倍选择性的最有前途的化合物。该化合物显示出组成的多目标概况,并有望抑制自身诱导的和AChE诱导的Aβ聚集以及抗氧化活性。
