In this communication, we report the synthesis and cholinesterase (ChE)/monoamine oxidase (MAO) inhibition of 19 quinolinones (QN1-19) and 13 dihydroquinolinones (DQN1-13) designed as potential multitarget small molecules (MSM) for Alzheimer’s disease therapy. Contrary to our expectations, none of them showed significant human recombinant MAO inhibition, but compounds QN8, QN9, and DQN7 displayed promising
在本通讯中,我们报告了19种喹啉酮(QN1-19)和13种二氢喹啉酮(DQN1-13)的合成和胆碱酯酶(ChE)/单胺氧化酶(MAO)抑制作用,这些喹啉酮被设计为阿尔茨海默氏病治疗的潜在多靶标小分子(MSM)。与我们的预期相反,它们均未显示出对人重组MAO的显着抑制作用,但化合物QN8,QN9和DQN7显示出了有希望的人重组乙酰胆碱酯酶(hrAChE)和丁酰胆碱酯酶(hrBuChE)抑制作用。特别是,发现分子QN8是hrAChE的有效且选择性非常强的非竞争性抑制剂(IC50 = 0.29 µM),Ki值在纳摩尔范围内(79 nM)。相关的对接分析证实了该结果,表明该配体是进一步研究的有趣命中。
