Abstract

A series of novel 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 tumorcelllines 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 cell lines with IC value lower than 1.0μM. Annexin V/FITC-PI assay showed that compound 7e induced apoptosis in HepG2 cells with a dose-dependent manner. Western blotting analysis indicated that compound 7e induced cell cycle arrest in G2/M phase by p53-depedent pathway.

摘要

合成了一系列新型4(1H)-喹诺酮衍生物,并对其体外抗增殖活性进行了评估。结果表明,这些化合物对一组人肿瘤细胞系表现出比先导化合物7-氯-4(1H)-喹诺酮1更强的抗增殖作用。发现化合物7e是最有效的抗增殖剂,对HepG2细胞系表现出选择性细胞毒活性,IC值低于1.0μM。膜联蛋白V/异硫氰酸荧光素-碘化丙啶检测表明,化合物7e以剂量依赖方式诱导HepG2细胞凋亡。蛋白质印迹分析表明,化合物7e通过p53依赖途径诱导细胞周期阻滞在G2/M期。
