Two series of novel 2-arylvinyl-naphtho[2,3-d]imidazol-3-ium iodide derivatives and 2-arylvinyl-naphtho[2,3-d]imidazol-3-ium bromide derivatives were designed and synthesized by the structural combination of YM155 with stilbenoids. All compounds were tested for anti-proliferative activity against PC-3, A375 and HeLa human cancer cell lines. Two of the compounds were selected for further investigation:
设计并合成了两个系列的新型2-芳基乙烯基萘[2,3- d ]咪唑-3-溴化碘衍生物和2-芳基乙烯基萘[2,3 - d ]咪唑-3-溴化碘衍生物。YM155与类胡萝卜素的组合。测试所有化合物对PC-3,A375和HeLa人癌细胞系的抗增殖活性。选择了两种化合物进行进一步研究:12b,对三种测试的细胞系均表现出强大的细胞毒性,IC 50值在0.06-0.21μM范围内,而7l对具有IC的PC-3细胞显示出优异的选择性仅22 nM中的50。蛋白质印迹分析结果表明,两种12b7l和7l抑制Bcl-2和Survivin蛋白的表达,有助于诱导细胞凋亡。如膜联蛋白V-FITC阳性凋亡细胞的百分比所确定,在PC-3细胞中浓度为100 nM时,12b不仅比7l更有效,而且还以剂量依赖性方式诱导细胞凋亡,效力高于7l。在A375细胞中浓度为1000 nM。因此,选择化合物12b用于进一步深入研究以研究细胞凋亡
