4(1H)-quinolone derivatives was synthesized and evaluated for antiproliferative activity in vitro. The results showed that these compounds exhibited more potent antiproliferative effect against a panel of human tumor cell lines than the lead compound 7-chloro-4(1H)-quinolone 1. Compound 7e was found to be the most potent antiproliferative agent and to exhibit selective cytotoxic activity against HepG2
合成了一系列新颖的4(1 H)-喹诺酮衍生物,并评价了其体外抗增殖活性。结果表明,这些化合物对人类肿瘤细胞系显示出比先导化合物7-chloro-4(1 H)-quinolone 1更有效的抗增殖作用。发现化合物7e是最有效的抗增殖剂,并且对HepG2细胞系表现出选择性的细胞毒活性,IC 50值低于1.0μM。膜联蛋白V / FITC-PI测定表明化合物7e以剂量依赖性方式诱导HepG2细胞凋亡。蛋白质印迹分析表明化合物7e 通过依赖p53的途径诱导G2 / M期细胞周期停滞。
