A new series of tacrine-coumarin hybrids linked to 1,2,3-triazole were designed, synthesized, and tested as potent dual binding site cholinesterase inhibitors (ChEIs) for the treatment of Alzheimer's disease (AD). Among them, compound 8e was the most potent anti-AChE derivative (IC50 = 27 nM) and compound 8m displayed the best anti-BChE activity (IC50 = 6 nM) much more active than tacrine and donepezil
设计,合成和测试了与1,2,3-三唑连接的新系列他克林-香豆素杂合体,并将其作为有效的双结合位点胆碱酯酶抑制剂(ChEIs)用于治疗阿尔茨海默氏病(AD)。其中,化合物8e是最有效的抗AChE衍生物(IC50 = 27 nM),化合物8m显示出最佳的抗BChE活性(IC50 = 6 nM),其活性比他克林和多奈哌齐为参比药物。还评估了化合物8e的BACE1抑制活性和对暴露于Aβ25-35的PC12细胞的神经保护性,这表明其活性较低。最后,通过莫里斯水迷宫任务进行的体内研究表明,化合物8e可显着逆转东碱诱导的大鼠记忆缺陷。
