series of new aryloxyacetamide derivatives 10a-s and 14a-m are designed and synthesized. Their protective activities against the glutamate-induced cell death were investigated in differentiated rat pheochromocytoma cells (PC12 cells). Most compounds exhibited neuroprotective effects, especially for 10m, 10r, 14b and 14c, which showed potential protection of PC12 cells at three doses (0.1, 1.0, 10muM)
设计并合成了一系列新的芳氧基乙酰胺衍生物10a-s和14a-m。在分化的大鼠嗜铬细胞瘤细胞(PC12细胞)中研究了它们对谷氨酸诱导的细胞死亡的保护活性。大多数化合物表现出神经保护作用,尤其是对10m,10r,14b和14c表现出神经保护作用,在三种剂量(0.1、1.0、10μM)下,PC12细胞都有潜在的保护作用。MTT分析,Hoechst 33342 / PI双重染色和高含量筛选(HCS)显示,用10m,10r,14b和14c预处理细胞以剂量依赖的方式显着降低了细胞凋亡的程度。蛋白质印迹分析的结果表明,这些化合物通过caspase-3途径抑制了谷氨酸诱导的PC12细胞凋亡。这些化合物可以是用于进一步发现用于治疗脑缺血性中风的神经保护剂的先导化合物。还介绍了基本的结构-活性关系。
