A series of 4-aminoalkyl-1(2H)-phthalazinone derivatives was designed and synthesized as potential multifunctional agents for Alzheimer's disease (AD) treatment. In vitro biological assay results demonstrated that most synthesized compounds exhibited significant AChE inhibition, moderate to high MAOs inhibitory potencies and good anti-platelet aggregation abilities. Among them, compound 15b exhibited
设计并合成了一系列 4-氨基烷基-1(2 H )-酞嗪酮衍生物作为治疗阿尔茨海默病 (AD) 的潜在多功能药物。体外生物测定结果表明,大多数合成的化合物表现出显着的 AChE 抑制、中到高度的 MAO 抑制效力和良好的抗血小板聚集能力。其中,化合物15b对 MAO-B 和 MAO-A 表现出最高的抑制效力(IC 50 分别为 0.7 µM 和 6.4 µM),对 AChE 的抑制作用中等(IC 50 = 8.2 µM),以及对自身和铜的良好活性2+诱导的 A β 1–42聚集和血小板聚集。此外,15b还显示出抗氧化、神经保护效力、抗神经炎症和 BBB 通透性。这些优异的结果表明,化合物15b值得进一步研究,被认为是治疗 AD 的有前途的多功能候选物。
