and evaluated as novel dual inhibitors of amyloid-β aggregation and monoamine oxidases. Among them, compounds 9a–d exhibited good inhibition of self-induced Aβ1-42 aggregation with inhibition ratio 57.7–71.5%. For MAO, these new hybrids exhibited good balance of inhibition for MAO-A and MAO-B. In addition, all target compounds retained the antioxidant activity of edaravone, showed equal or better antioxidant
考虑到阿尔茨海默氏病(AD)的复杂病因,多功能药物可能对该病的治疗有益。设计,合成和评估了一系列DL -3-正丁基邻苯二甲酸酯-依达拉奉杂种,作为淀粉样β聚集和单胺氧化酶的新型双重抑制剂。其中,化合物9A - d显示出的自诱导良好的抑制β 1-42聚集,抑制率57.7–71.5%。对于MAO,这些新杂种对MAO-A和MAO-B表现出良好的抑制平衡。此外,所有目标化合物均保留了依达拉奉的抗氧化活性,显示出与依达拉奉相同或更好的抗氧化活性。并行的人工膜通透性测定法对血脑屏障的测定结果表明,化合物9a – d将能够穿过血脑屏障并达到中枢神经系统的生物学目标。在所有测定中的有希望的结果表明,设计化合物背后的策略是合理且有利的。综上所述,这些初步发现表明,具有最强生物活性的化合物值得进一步研究以用于AD治疗的药理学发展。
