A series of novel 2,4,5-trisubstituted 1,3-thiazole derivatives containing hydrazide–hydrazine, and carboxamide moiety including 46 compounds T were synthesized, and evaluated for their antitumor activity in vitro against a panel of five human cancer cell lines. Eighteen title compounds T displayed higher inhibitory activity than that of 5-Fu against MCF-7, HepG2, BGC-823, Hela, and A549 cell lines
合成了一系列新颖的2,4,5-三取代1,3,3-噻唑衍生物,其中包括酰肼-肼,以及包括46个化合物T的羧酰胺部分,并评估了它们在体外对五种人类癌细胞系的抗肿瘤活性。18种标题化合物T对MCF-7,HepG2,BGC-823,Hela和A549细胞系的抑制活性高于5-Fu。尤其是,T1,T26和T38表现出最佳的IC 50细胞毒性活性分别针对MCF-7,BCG-823和HepG2细胞系的2.21μg/ mL,1.67μg/ mL和1.11μg/ mL值。这些结果表明,1,3-噻唑,酰肼-hydr和羧酰胺部分的组合对细胞毒性活性非常有利。此外,流式细胞仪分析表明,化合物T1和T38可以诱导HepG2细胞凋亡,并证实T38通过S细胞周期停滞诱导了细胞凋亡的诱导。
