A novel series of coumarin-lipoic acid conjugates were synthesized via cycloaddition click reaction to find out new multi-target-directed ligands (MTDLs) for treatment of Alzheimer's disease (AD). All of synthesized compounds were screened for neuroprotective and anti-cholinesterase activities. Based on primary screening, two compounds (5 and 11) were subjected to further biological evaluations. In particular, compound 11 which was the most potent AChE inhibitor showed good inhibitory effect on Aβ-aggregation and intracellular ROS (reactive oxygen species) formation, as well as the ability of selective bio-metal chelation and neuroprotection against H₂O₂- and Aβ_1-42-induced cytotoxicity. In the light of these results, the applied hybridization approach introduced new promising lead compound with desired multifunctional properties, being useful in the treatment of Alzheimer's disease.

通过环加成点击反应合成了一系列新的香豆素-硫辛酸缀合物，以发现新的多靶标定向配体（MTDL），用于治疗阿尔茨海默氏病（AD）。筛选所有合成的化合物的神经保护和抗胆碱酯酶活性。基于初步筛选，对两种化合物（5和11）进行了进一步的生物学评估。特别是，最有效的AChE抑制剂化合物11对Aβ聚集和细胞内ROS（活性氧）的形成具有良好的抑制作用，以及对H ₂ O _2-和H ₂ O ₂有选择性的生物金属螯合和神经保护的能力。Aβ _1-42诱导的细胞毒性。根据这些结果，应用的杂交方法引入了具有希望的多功能特性的新的有前途的先导化合物，可用于治疗阿尔茨海默氏病。
