cell lines. Compounds 6h, 6d, 7a, and 7d exhibited more potent antiproliferative effects than the other compounds. Especially, compounds 6d and 7d displayed NQO1-dependent cytotoxicity and competitive NQO1 inhibitory effects in both drug sensitive HeLaS3 and multidrug resistant KB-vin cell lines. Furthermore, compounds 6h, 6d, 7a, and 7d induced a dose-dependent lethal mitochondrial dysfunction in both
通过在喹啉-5,8-的C6-或C7-位偶联不同的烷基或芳基氨基片段,设计并合成了十四种新颖的氨基喹啉-5,8-二酮衍生物(6a-h和7a-h)。 dione。在药物敏感性HeLaS3和耐多药KB-vin细胞系中,所有目标化合物均在低微摩尔范围内显示出抗增殖能力。与其他化合物相比,化合物6h,6d,7a和7d表现出更强的抗增殖作用。特别是化合物6d和7d在对药物敏感的HeLaS3和对多药耐药的KB-vin细胞系中均显示出NQO1依赖性的细胞毒性和竞争性NQO1抑制作用。此外,化合物6h,6d,7a和7d通过增加细胞内活性氧(ROS)水平,在药物敏感性HeLaS3和多药耐药KB-vin细胞中诱导了剂量依赖性致死线粒体功能障碍。值得注意的是,化合物7d在体外选择性抑制癌细胞,但不抑制非肿瘤肝细胞增殖并通过剂量依赖性方式调节Bcl-2,Bax和裂解的caspase-3凋亡蛋白显着触发HeLaS3细
