A series of deoxyvasicinone derivatives with benzenesulfonamide substituents were designed and synthesized to find a multifunctional anti-Alzheimer's disease (AD) drug. The results of the biological activity evaluation indicated that most compounds demonstrated selective inhibition of acetylcholinesterase (AChE). Among them, g17 exhibited the most potent inhibitory effect on AChE (IC50 = 0.24 ± 0.04 μM)
设计并合成了一系列带有苯磺酰胺取代基的脱氧凡西酮衍生物,以寻找多功能的抗阿尔茨海默病(AD)药物。生物活性评价结果表明,大多数化合物对乙酰胆碱酯酶(AChE)具有选择性抑制作用。其中, g17对AChE的抑制作用最强(IC 50 = 0.24 ± 0.04 μM)。此外, g17作为金属螯合剂和淀粉样 β 肽自聚集抑制剂表现出有前景的特性 (68.34 % ± 1.16 %)。氧化应激研究表明, g17具有神经保护作用,可有效抑制细胞内活性氧的积累。此外, g17通过显着减少促炎细胞因子(如NO、IL-1β和TNF-α)的产生并抑制炎症介质iNOS和COX-2的表达而表现出显着的抗神经炎症作用。体内研究表明, g17显着改善了 AD 模型小鼠的认知和记忆能力。使用苏木精和伊红染色对小鼠海马组织切片进行组织学检查表明, g17可以有效减轻神经元损伤。考虑到g17的多功能特性,它被认为是治疗 AD
