the management of Alzheimer's disease and to develop in-vivo active multifunctional cholinergic inhibitors, we embarked on the development of ferulic acid analogs. A systematic SAR study to improve upon the cholinesterase inhibition of ferulic acid with analogs that also had lower logP was carried out. Enzyme inhibition and kinetic studies identified compound 7a as a lead molecule with preferential
为了克服克服与天然产物有关的阿尔茨海默氏病管理的局限性并开发体内活性多功能胆碱能抑制剂的总体目标,我们着手开发阿魏酸类似物。进行了系统的SAR研究,以改善LogP值较低的类似物对阿魏酸对胆碱酯酶的抑制作用。酶抑制和动力学研究确定化合物7a为具有优先乙酰胆碱酯酶抑制作用的先导分子(AChE IC50 = 5.74±0.13μM; BChE IC50 = 14.05±0.10μM)与母体阿魏酸(20μM时AChE和BChE的抑制% ,分别为15.19±0.59和19.73±0.91)。分子对接和动力学研究表明7a非常适合AChE和BChE的活性位点,与AChE中的关键残基Asp74,Trp286和Tyr337以及BChE中的Tyr128,Trp231,Leu286,Ala328,Phe329和Tyr341形成稳定而强的相互作用。在DPPH分析中发现化合物7a是有效的抗氧化剂(IC50 = 57
