中文摘要: 在抗肿瘤药的研发中,微管蛋白抑制剂及DNA拓扑异构酶抑制剂作为细胞毒药物的重要代表一直是研究热点。临床上DNA拓扑异构酶Ⅱ抑制剂和微管蛋白抑制剂经常联合用药,其优点是能对癌症的治疗起到协同作用、减少毒副作用,在一定程度上还能减缓肿瘤的耐药性。考虑到拓扑异构酶Ⅱ和微管蛋白的双重抑制剂将比联合用药更为简便和易于控制,本课题拟在前期工作的基础上(已获得全新结构的化合物I-4,是微管/拓扑Ⅱ双重抑制剂,有良好的体外抗肿瘤活性及抗耐药性),利用经典药物化学手段和计算机辅助设计,优化合成具有拓扑Ⅱ和微管蛋白双重抑制作用的化合物,考察其构效关系,着重改善其溶解度和体内成药性,发展一类具有自主知识产权的新型候选药物,使其有可能克服因单一作用靶点突变而引起的耐药,从而解决耐药性问题。

英文摘要: Tubulin inhibitors and DNA topoisomerase inhibitors have been hot areas of anti-tumor research for several years. There is a pressing need in the clinical treatment of human cancer for combination of the drugs tubulin inhibitors and Topo Ⅱto reduce the lousy reaction and drug resistance by the cooperative action. We have developed a direct, rapid and practicalone-pot tandem reaction for the synthesis of 2 or 2,4-substituted-α-carbolines including compound I - 4, dual inhibitors of microtubules/Topo Ⅱ,which has good antitumor activity in vitro and drug resistance. The goal of this project is to design and synthesis of microtubules/Topo Ⅱdual inhibitors based on the previous work, in silico screening and bioassays.The novel compound not only provide invaluable tools for investigating the complex resistance mechanism but also offer considerable opportunities for the treatment of cancers.
