吡咯并吡啶类整合酶抑制剂的设计、合成和生物活性研究

摘要

Objective To design and synthesze novel pyrrolopyridine as integrase inhibitors. Method The launched anti-HIV drug raltegravir was selected as template compounds. According to the concept of bioisosterism and molecular docking ,a series of pyrrolopyridine compounds(6a-6t)were designed,synthesized and their anti-integrase 3′-processing activity were analyzed. Re⁃sults The designed compounds were successfully synthesized and the structures of these compounds were confirmed by 1H NMR,13C NMR and ESI-HRMS. The anti-IN 3′-P activity of these compounds were also measured. The binding mode and docking energy of rep⁃resentative compounds were analyzed. Conclusion The structure-activity relationships of these compounds were also analyzed by the results of docking. These results lay the foundation for the further optimization of these compounds.%目的：设计并合成新型的吡咯并吡啶类整合酶抑制剂。方法利用生物电子等排和分子对接方法，以已上市药物雷特格韦作为前体设计了一系列吡咯并吡啶类整合酶抑制剂（6a~6t），通过全合成方法得到目标产物，并测定这些化合物对整合酶3′加工抑制活性。结果成功合成了所设计的吡咯并吡啶类化合物，产物结构经过1H NMR、13C NMR和高分辨质谱确证。部分化合物都显示出一定的整合酶3′加工抑制活性，同时对特定化合物进行了分子对接及结合能量的分析。结论通过分子对接的方法对目标产物进行了构效关系的分析，阐明了该类化合物的作用机制，并为该类化合物的继续优化奠定了基础。
