A series of twelve 4-methyl-2-(2-, 3- and 4-pyridinyl)quinolines 7–9 was synthesized using modified Kametani reaction protocol and their in vitro cytotoxicity was tested against human cancer cell lines MCF-7, SKBR-3, PC3, HeLa, comparing with human dermis fibroblast as non-tumor cells. In general, these molecules displayed potent anticancer properties, but also demonstrated a narrow safe margin, as
使用改良的Kametani反应方案合成了一系列十二个4-甲基-2-(2-,3-和4-吡啶基)喹啉7-9,并测试了它们对人癌细胞MCF-7,SKBR-的细胞毒性。 3,PC3,HeLa,与人真皮成纤维细胞比较为非肿瘤细胞。通常,这些分子显示出有效的抗癌特性,但也显示出窄的安全限度,就像对阿霉素所观察到的那样。化合物8a,8b,9a和9d具有较高的IC 50表现出显着的选择性细胞毒性与参考药物阿霉素在前列腺癌,宫颈上皮癌和乳腺癌中的比较值(没有过表达HER2 / c-erb-2基因)。4-甲基-2-(3-吡啶基)喹啉(8A)由它的低的非特异性细胞毒性突出(IC 50 = 476.69μM)和PC3细胞中高度选择性出色的(IC 50 = 4.40μM)作为抗肿瘤一个有趣的模型抗前列腺癌的药物。 与阿霉素(IC 50 = 3.62 µM,SI = 0.7)相比,其4-吡啶基类似物9a对HeLa细胞(IC
