简介：对化合物[Na_2（H_2O）_（10）][Cu_4（H_2O）_（12）（H_2W_（12）O_（42））]·15H_2O（简称Na_2Cu_4W_（12））进行了体外抗肿瘤活性研究.应用四甲基偶氮唑盐（3-[4,5-dimethylthiazo-2-y]-2,5-diphenyltetrazoliumbromide,MTT）比色法分析Na_2Cu_4W_（12）对人肝癌细胞（HepG2）、人神经母细胞瘤细胞（SHY5Y）增殖抑制活性.采用光学显微镜观察肿瘤细胞的凋亡形态变化,用流式细胞术分析细胞周期和细胞凋亡,计算各期细胞比例及细胞凋亡率.结果表明,Na_2Cu_4W_（12）对HepG2和SHY5Y2种肿瘤细胞增殖半数抑制浓度IC_（50）值分别为5.3和10.2μmol·L~（-1）,且呈剂量依赖性.光学显微镜下处理组细胞出现皱缩、变圆、缩小等形态变化,不同浓度Na_2Cu_4W_（12）处理12h早期凋亡细胞所占的百分比显著增加且呈剂量依赖性.综上所述,Na_2Cu_4W_（12）能够抑制胞瘤细胞增殖,诱导细胞凋亡.
