Novel 6,7-methylenedioxy-4-substituted phenylquinolin-2(1H)-one derivatives 12a–n were designed and prepared through an intramolecular cyclization reaction and evaluated for in vitro anticancer activity. Among the synthesized compounds, 6,7-methylenedioxy-4-(2,4-dimethoxyphenyl)quinolin-2(1H)-one (12e) displayed potent cytotoxicity against several different tumor cell lines at a sub-micromolar level
通过分子内环化反应设计和制备了新型 6,7-亚甲二氧基-4-取代的苯基喹啉-2(1 H )-one 衍生物12a – n,并评估了其体外抗癌活性。在合成的化合物中,6,7-亚甲二氧基-4-(2,4-二甲氧基苯基)喹啉-2(1 H )-one ( 12e ) 在亚微摩尔水平对几种不同的肿瘤细胞系显示出有效的细胞毒性。此外,荧光激活细胞分选 (FACS) 分析的结果表明12e诱导细胞周期停滞在 G2/M 期,伴随着 HL-60 和 H460 细胞的凋亡。Hoechst 染色和 caspase-3 激活证实了这一作用。由于其易于合成和显着的生物活性,4-苯基喹啉-2(1 H )-one 类似物 (4-PQs) 是基于喹啉支架的有前途的新型抗癌先导物。因此,化合物12e被鉴定为一种新的先导化合物,值得进一步优化和开发作为抗癌候选物。
