- W3175603989 abstract "对3-芳基香豆素母核进行修饰,以芳基乙酸和水杨醛为起始原料,三乙胺为催化剂,乙酸酐为溶剂,经缩合反应分别引入吸电子基团三氟甲基和给电子基甲氧基,合成了3-(4'-三氟甲基苯基)香豆素(2a)和新化合物3-(4'-甲氧基苯基)香豆素(2b),其结构经UV-Vis、1H NMR、IR和MS表征.并对其生物活性和荧光标记特性进行了研究.结果 表明:2a和2b显示较强的细胞增殖抑制活性、抑菌活性,浓度为4000 μmol·L-1时,对ECV304细胞的抑制率分别为84.22％和65.56％,对大肠杆菌、绿脓杆菌和金黄色葡萄球菌均显示抑菌活性,具有较好的荧光特性,可用于细胞染色及荧光标记." @default.
