A series of new quinolinederivatives of ursolic acid were designed and synthesized in an attempt to develop potential anticancer agents. The structures of these compounds were identified by 1H NMR, 13C NMR, IR and ESI-MS spectra analysis. The target compounds were evaluated for their in vitro cytotoxicity against three human cancer cell lines (MDA-MB-231, Hela and SMMC-7721). From the results, compounds
设计并合成了一系列新的熊果酸喹啉衍生物,以试图开发潜在的抗癌药。这些化合物的结构通过1 H NMR,13 C NMR,IR和ESI-MS光谱分析鉴定。评价靶标化合物对三种人类癌细胞系(MDA-MB-231,Hela和SMMC-7721)的体外细胞毒性。从结果来看,化合物3a - d对三种癌细胞显示出显着的抗肿瘤活性。尤其是,发现化合物3b是IC 50最有效的衍生物对于MDA-MB-231,HeLa和SMMC-7721细胞,其分别为0.61±0.07、0.36±0.05、12.49±0.08μM的值要强于阳性对照依托泊苷。此外,膜联蛋白V-FITC / PI双重染色测定法揭示化合物3b可以剂量依赖性方式显着诱导MDA-MB-231细胞的凋亡。细胞周期分析还表明,化合物3b可引起MDA-MB-231细胞在G0 / G1期的细胞周期停滞。
