molecules are selective AChE inhibitors. 13b (most potent AChE inhibitor) also showed copper-induced Aβ1-42 aggregation inhibition (34.26 % at 50 μΜ) and chelating properties for metal ions (Cu2+, Fe2+, and Zn2+) involved in AD pathogenesis along with DNA protective potential against degenerative actions of ∙OH radicals. Molecular modelling studies confirm the potential of 13b in blocking both PAS and
基于多奈哌齐骨架的新型三唑系香豆素-苯并三唑杂化物系列已被设计和合成为多功能药物,用于治疗阿尔茨海默氏病(AD)。中合成的化合物13b中显示最有效的乙酰胆碱酯酶抑制(IC 50 = 0.059 μM)具有混合类型抑制方案。构效关系表明,连接香豆素和三唑的三碳烷基链具有良好的抑制潜力。从4-羟基香豆素和1-苯并三唑获得的杂种是最有效的AChE抑制剂。还评估了所有化合物对丁酰胆碱酯酶的抑制潜力,但所有化合物的活性均可以忽略不计,表明杂合分子是选择性的AChE抑制剂。13B(最有效的胆碱酯酶抑制剂对)也显示铜诱导Aβ 1-42聚集抑制(34.26在50%μ为金属离子(铜Μ)和螯合性能2+,铁2+,和Zn 2+)参与了AD的发病机制,并具有针对∙OH自由基的降解作用的DNA保护潜力。分子模型研究证实了13b在阻断AChE的PAS和CAS中的潜力。此外,还简化了13b与Aβ1-42单体的相互作用。因
