A series of structurally new diheteroaryl thioether analogs was designed, prepared and screened toward MGC-803, MKN-45, EC-109 and H1650. Most of the target compounds displayed moderate to potent antiproliferative activities. Among them, compound 5 showed the best antiproliferative activity against the tested cell lines with the half maximal inhibitory concentration (IC50) values below 10 μM. In addition
针对MGC-803,MKN-45,EC-109和H1650,设计,制备并筛选了一系列结构上新的二杂芳基硫醚类似物。大多数目标化合物显示出中等至有效的抗增殖活性。其中,化合物5对测试的细胞系表现出最佳的抗增殖活性,其半数最大抑制浓度(IC 50)值低于10μM。另外,流式细胞仪分析表明,化合物5增加Bax表达,下调Bcl-2表达,切割caspases-3 / 9,最终诱导MKN-45细胞凋亡,并使细胞周期停滞在G2 / M期。这项研究表明,二杂芳基硫醚是用于开发抗肿瘤剂或生物探针的一类新兴化学型,化合物5可作为设计新的细胞凋亡诱导剂的良好起点。
