thiosemicarbazone derivatives were designed and synthesized as potent anticancer agents. All these compounds were identified by 1H NMR, 13C NMR, HR-MS spectra analyses. In the in vitro anticanceractivity, most derivatives showed considerable cytotoxic activity against three human cancer cell lines (MDA-MB-231, SMMC-7721 and Hela). Among them, compound 4i exhibited most potent antitumor activity against three
设计并合成了一系列新的基于壬基酮的硫半碳zone酮衍生物作为有效的抗癌剂。所有这些化合物均通过1 H NMR,13 C NMR,HR-MS光谱分析鉴定。在体外抗癌活性中,大多数衍生物对三种人类癌细胞系(MDA-MB-231,SMMC-7721和Hela)表现出相当大的细胞毒性活性。其中,化合物4i对三种癌细胞具有最强的抗肿瘤活性,IC50值分别为2.79±0.38、2.64±0.17和3.64±0.13μM。此外,细胞周期分析表明化合物4i引起MDA-MB-231细胞在G2 / M期的细胞周期停滞。膜联蛋白V-FITC / 7-AAD双重染色测定法还显示化合物4i诱导了MDA-MB-231细胞的早期凋亡。
