Looking for an effective anti-Alzheimer’s agent is very challenging; however, a multifunctional ligand strategy may be a promising solution for the treatment of this complex disease. We herein present the design, synthesis and biological evaluation of novel hydroxyethylamine derivatives displaying unique, multiple properties that have not been previously reported. The original mechanism of action combines
寻找有效的抗阿尔茨海默氏症药物非常具有挑战性;然而,多功能配体策略可能是治疗这种复杂疾病的有希望的解决方案。我们在此介绍了新型羟乙胺衍生物的设计、合成和生物学评估,这些衍生物具有以前从未报道过的独特、多种特性。最初的作用机制结合了对疾病修饰靶标的抑制活性:β-分泌酶 (BACE1) 和淀粉样蛋白 β (Aβ) 聚集,以及对与症状缓解相关的靶标的影响 - 抑制丁酰胆碱酯酶 (BuChE) 和γ-氨基丁酸酸转运蛋白 (GAT)。在获得的分子中,化合物36表现出最平衡和最广泛的活性谱(ee AChE IC50 = 2.86 μM;eq BuChE IC 50 = 60 nM;h BuChE IC 50 = 20 nM;h BACE1 IC 50 = 5.9 μM;10 μM 时对 Aβ 聚集的抑制 = 57.9%;m GAT1 IC 50 = 10.96 μM;和m GAT2 IC 50
