In a continuing effort to develop multitargeted compounds as potential treatment agents against Alzheimer’s disease (AD), a series of chromone derivatives were designed, synthesized and evaluated. In vitro assay indicated that most of the target compounds have both MAOs inhibition activities, antioxidant activity and biometal chelating ability. Especially, compound s19 exhibits good inhibitory potency
在不断开发多目标化合物作为对抗阿尔茨海默氏病(AD)的潜在治疗剂的过程中,设计,合成和评估了一系列色酮衍生物。体外测定表明,大多数目标化合物均具有MAOs抑制活性,抗氧化活性和生物金属螯合能力。特别是,化合物S19用于抑制MAOS(IC的表现出良好的抑制效力50值5.12μM为ħ MAO-A和0.816μM为ħ MAO-B),A的中等抑制β聚集(75.1%,在20μM),金属螯合,控制ROS的产生和抗氧化活性(ORAC = 3.62)。另外,s19可以减少氧化应激诱导的PC12细胞死亡并穿透血脑屏障(BBB)。综上所述,这些结果表明,s19可能是用于AD治疗的有希望的多靶点化合物。
