inhibition and its kinetic data suggested 6j as the lead molecule (AChE IC50 = 2.13 ± 0.015 µM, BChE = 28.19 ± 0.20%), in comparison to PA (AChE = 7.14 ± 0.98%) which was further selected for various biological studies in AD models. 6j, exhibited interaction with the peripheral anionic site of AChE, BBB permeability (Pe = 7.98), and antioxidant property (% radical scavenging activity = 35.41 ± 1.09, 2.43 ± 1
抽象的 在本文中,我们开发了一系列胡椒酸( PA )类似物,旨在克服天然产品在治疗阿尔茨海默病(AD)方面的局限性。进行了全面的 SAR 研究以增强PA的胆碱酯酶抑制作用。乙酰胆碱酯酶抑制及其动力学数据表明6j作为先导分子(AChE IC 50 = 2.13 ± 0.015 µM ,BChE = 28.19 ± 0.20%),与进一步选择用于各种生物活性的PA (AChE = 7.14 ± 0.98%)相比。 AD 模型研究。 6j表现出与 AChE 外周阴离子位点的相互作用、BBB 通透性 ( Pe = 7.98) 和抗氧化性能(% 自由基清除活性 = 35.41 ± 1.09、2.43 ± 1.65,对于6j和PA在 20 M \(\mu \) , 分别)。金属螯合研究的结果表明, 6j不能有效地螯合铁。分子模型研究表明6j可以有效地与AChE的Ser293、Phe295、Arg29
