A series of quinazolin-4(3H)-one derivatives bearing dithiocarbamate side chain at the C2-position were synthesized and evaluated for their antiproliferative activities against A549, MCF-7, HeLa, HT29 and HCT-116 cell lines. Most of the synthesized compounds exhibited broad spectrum antitproliferative activity against five cell lines, of which 5c was the most potent against HT29 cell line with an IC50
合成了一系列在C2位带有二硫代氨基甲酸酯侧链的quinazolin-4(3 H)-one衍生物,并评估了其对A549,MCF-7,HeLa,HT29和HCT-116细胞系的抗增殖活性。大多数合成的化合物对五种细胞系均表现出广谱抗增殖活性,其中5c对HT29细胞系最有效,IC 50值为5.53μM,在HT29细胞中诱导了G2 / M期停滞。用5c处理HT29细胞会导致BubR1磷酸化,并以时间依赖性方式增加有丝分裂指数。此外,5c促进了微管蛋白的体外聚合。这些结果表明,在C2位带有二硫代氨基甲酸酯侧链的quinazolin-4(3 H)-one衍生物可能是靶向微管蛋白以激活纺锤体装配检查点的潜在新型抗肿瘤药。
