  摘要：

  已经设计并合成了二十七个3-（苯并[ d ]噻唑-2-基）-4-氨基喹啉衍生物作为拓扑异构酶I抑制剂。在体外针对四种人类肿瘤细胞系（MGC-803，人肝癌HepG-2，T24，和NCI-H460）和一个正常细胞系的抗增殖评价（HL-7702）表示，其中大部分表现出强的细胞毒性。其中，5a被认为是最有前途的候选物，其IC 50值低至约2.20±0.14，并被选作进一步探索。光谱分析和琼脂糖凝胶电泳分析表明5a可以与DNA相互作用并强烈抑制拓扑异构酶I（Topo I）。进一步筛选化合物5b的Topo I活性，5c，5e，5f，5h，5i，5j，5l和5n表明一些化合物可能与5a具有完全不同的细胞毒性。分子建模研究证实5a采用独特的模式与DNA和Topo I相互作用。其他分子机理研究表明，用5a处理MGC-803细胞可诱导S期阻滞，上调促凋亡蛋白，下调抗凋亡蛋白，激活caspase-3，随后诱导
