Three series of novel spin-labeled rotenone derivatives were synthesized and evaluated for cytotoxicity against four tumor cell lines, A-549, DU-145, KB and KBvin. All of the derivatives showed promising in vitro cytotoxic activity against the tumor cell lines tested, with IC50 values ranging from 0.075 to 0.738 μg/mL. Remarkably, all of the compounds were more potent than paclitaxel against KBvin
合成了三个系列的新型自旋标记鱼藤酮衍生物,并评估了它们对四种肿瘤细胞系A-549,DU-145,KB和KBvin的细胞毒性。所有衍生物均显示出对测试的肿瘤细胞系有希望的体外细胞毒性活性,IC 50值范围为0.075至0.738μg/ mL。值得注意的是,所有化合物在体外对KBvin的作用均优于紫杉醇,并且化合物3a和3d对这种细胞系表现出最高的细胞毒性(IC 50分别为0.075和0.092μg/ mL)。基于观察到的细胞毒性,已经描述了结构-活性关系。
