[目的] 从天然产物中筛选人类免疫缺陷病毒(HIV)非核苷类逆转录酶抑制剂(NNRTI)和整合酶链转移抑制剂(INSTI)作用位点的双靶点抑制剂[RT (NNRTI)/IN]。[方法] 运用分子模拟技术和计算机辅助药物设计(CADD)方法,构建HIV RT (NNRTI)/IN双靶点抑制剂分子相似性搜索模型、NNRTI和RT以及INSTI和IN对接模型,采用两种策略对中药化学数据库(TCMD)进行筛选。[结果] 共命中与RT和IN对接得分均大于6的化合物35个,包括黄酮类、生物碱类、苷类、多酚类等,黄酮类化合物(15个)占到了42.86%。[结论] 黄酮类化合物是开发潜在HIV RT (NNRTI)/IN双靶点抑制剂的主要来源,上述研究为天然产物来源的HIV双靶点药物发现提供了新线索。 |

Abstract: |
[Objective] To find double target inhibitor of RT(NNRTI)/IN against HIV from natural products.[Methods] Molecular simulation and CADD technologies were used to build molecular similarity search model of double target inhibitor of RT(NNRTI)/IN against HIV, docking model of NNRTI and RT, docking model of INSTI and IN. Two strategies were used to screen Traditional Chinese Medicine Database(TCMD).[Results] The 35 molecules which docking scores with RT and IN were both above 6 were hit. There were flavonoids, alkaloids, glycosides, polyphenols, etc. Flavonoids(15) accounted for 42.86%.[Conclusion] Flavonoids are the main sources for the development of potential double target inhibitor of RT(NNRTI)/IN against HIV. These results provide new clues for the study of the dual target drugs of HIV derived from natural products. |
