A series of 3-(trimethoxyphenyl)-2(3H)-thiazole thiones 5 were designed as new heterocyclic analogs of combretastatin A-4 (CA-4). Indeed, the olefinic core structure of CA-4 has been replaced by 2(3H)-thiazole thione. The general synthetic strategy to prepare compounds 5 was based on the cyclocondensation reaction between triethylammonium N-(trimethoxyphenyl)dithiocarbamate and appropriate phenacyl
一系列的3-(三甲氧基苯基)-2(3 H)-噻唑硫酮5被设计为康布雷他汀A-4(CA-4)的新杂环类似物。实际上,CA-4的烯烃核心结构已被2(3 H)-噻唑硫酮取代。制备化合物5的一般合成策略是基于N-(三甲氧基苯基)二硫代氨基甲酸三乙铵与适当的苯甲酰卤之间的环缩合反应。3-(三甲氧基苯基)-2(3 H)-噻唑硫酮5对人癌细胞系T47D,MCF-7和MDA-MB-231的细胞毒活性评估表明4-甲基类似物5f对所有细胞系表现出最高的活性。化合物5f对非肿瘤细胞MRC-5没有明显的毒性,并且其细胞毒性显然对癌细胞具有选择性。生物测定的结果表明,代表性化合物5f使微管蛋白解聚,抑制细胞增殖,并诱导癌细胞凋亡。
