of novel molecules were developed. All synthesized compounds were tested for their acetyl and butyryl cholinestrases (AChE and BChE) inhibitory properties. Enzyme inhibition and PAS binding studies identified compound 13b as a lead molecule with potent inhibitor property towards AChE/BChE (AChE IC50 = 0.96 ± 0.14 µM, BChE IC50 = 1.23 ± 0.23 µM) compared to earlier identified lead molecule EJMC-G (AChE
在我们之前的论文中,我们描述了基于阿魏酸 ( FA ) 模板的新型多功能胆碱酯酶 (ChE) 抑制剂系列,用于治疗 AD。本报告以校准的方式进一步扩展了该系列分子的构效关系 (SAR) 研究,以提高对 ChE 的抑制和抗氧化性能,从而鉴定出新型强效多功能分子。研究用苄基哌嗪取代苯基哌嗪环的效果,增加FA之间的接头长度和取代苯环,并在该分子模板上用色胺取代吲哚部分,开发了三个系列的新分子。测试了所有合成化合物的乙酰胆碱酯酶和丁酰胆碱酯酶(AChE 和 BChE)抑制特性。酶抑制和PAS结合研究鉴定的化合物13B,为先导分子朝向乙酰胆碱酯酶/ BChE的强效抑制剂属性胆碱酯酶(AChE的IC 50 = 0.96±0.14 μ男,IC的BChE 50 = 1.23±0.23 μ M)相比,先前确定先导分子EJMC- G(AChE IC 50 = 5.74 ± 0.13 μ M,BChE IC 50
