A series of novel donepezil derivatives was designed, synthesized and evaluated as multifunctional acetylcholinesterase (AChE) inhibitors for the treatment of Alzheimer's disease (AD). The screening results indicated that most of the compounds exhibited potent inhibition of AChE with IC50 values in the nanomolar range. Moreover, these derivatives displayed good antioxidant, Aβ interaction, blood-brain
设计,合成和评估了一系列新型多奈哌齐衍生物,作为多功能乙酰胆碱酯酶(AChE)抑制剂,用于治疗阿尔茨海默氏病(AD)。筛选结果表明,大多数化合物均表现出对AChE的有效抑制作用,IC 50值在纳摩尔范围内。此外,这些衍生物显示良好的抗氧化,A β相互作用,血脑屏障渗透(PAMPA-BBB +)和ADMET性质(在硅片)。其中,图5c显示了优秀的抑制乙酰胆碱酯酶(IC 50:85纳米的eeAChE,73纳米的HACHE),金属螯合,并在自感应,HACHE诱导和Cu抑制作用2+诱导的阿β 1-42聚合(18.5%,72.4%和46.3%,在20 μ M)。动力学分析和分子建模研究表明5c可以同时与AChE的催化活性位点(CAS)和外围阴离子位点(PAS)结合。更重要的是,5C表现出对一个显著的神经保护效力β 1-42诱导PC12细胞损伤。此外,逐步被动回避测试显示5c可以显着逆转东pol碱所
