A novel series of feruloyl-donepezil hybrid compounds were designed, synthesized and evaluated as multitarget drug candidates for the treatment of Alzheimer's Disease (AD). In vitro results revealed potent acetylcholinesterase (AChE) inhibitory activity for some of these compounds and all of them showed moderate antioxidant properties. Compounds 12a, 12b and 12c were the most potent AChE inhibitors
设计,合成和评估了一系列新的阿魏酰基-多奈哌齐杂化化合物,作为治疗阿尔茨海默氏病(AD)的多靶点候选药物。体外结果显示,其中某些化合物对乙酰胆碱酯酶(AChE)具有强抑制作用,并且所有化合物均显示出适度的抗氧化性能。化合物12a,12b和12c是最有效的AChE抑制剂,突出显示12a的IC50 = 0.46μM。此外,这三种最有希望的化合物在小鼠爪水肿,胸膜炎和福尔马林诱导的痛觉过敏模型,Cu2 +和Fe2 +的体外金属螯合剂活性以及人类神经元细胞抗氧化损伤的神经保护方面表现出显着的体内抗炎活性。分子对接研究证实了这些活性化合物对AChE相互作用的体外抑制模式。基于这些数据,化合物12a被鉴定为具有创新结构特征和多靶点作用的新型有希望的药物原型候选物,用于AD的治疗。
