摘　　要：【目的】基于网络药理学方法及分子对接技术,探讨补骨脂是否可能促进儿童性早熟及其潜在机制。【方法】通过BATMAN-TCM在线平台获取补骨脂主要活性成分及其作用靶点,从GeneCards数据库中获取性早熟相关疾病靶点,采用Cytoscape 3.7.1软件构建“活性成分-疾病靶点”可视化网络。基于STRING在线数据库进行蛋白质-蛋白质相互作用(PPI)的网络图构建。使用Metascape在线工具进行靶点基因的基因本体(GO)和京都基因与基因组百科全书(KEGG)通路的富集分析。从PubChem数据库中获取主要活性成分结构,从RCSB PDB数据库中获取核心靶点结构,导入Autodock进行分子对接,最后利用PyMOL软件绘制分子对接模拟图。【结果】得到12种补骨脂的活性成分,涉及274个靶点,其中11种活性成分和98个靶点与性早熟相关。主要活性化合物为豆甾醇、补骨脂酚、异补骨脂素、补骨脂查尔酮、补骨脂乙素、甲氧基补骨脂素,主要靶点有雌激素受体1(ESR1)、雌激素受体2(ESR2)、胰岛素样生长因子1(IGF1)、孕酮受体(PGR),主要涉及卵巢类固醇生成通路、Hippo信号通路。分子对接结果表明这些活性化合物与靶标具有良好的结合作用。【结论】补骨脂存在促进儿童性发育的可能性及具有潜在药理作用机制,分析结果可为儿童性早熟、青春期早发育等临床防治提供理论参考。Objective The network pharmacological methods and molecular docking technology were used for investigating the possibility of Psoraleae Fructus in promoting precocious puberty in children and its potential mechanism.Methods The main active ingredients of Psoraleae Fructus and their therapeutic targets were obtained from BATMAN-TCM online platform.The disease targets related with precocious puberty were obtained from GeneCards database.A visualized network of active ingredients-disease targets was constructed by Cytoscape 3.7.1 software.Protein-protein interaction(PPI)network diagrams were constructed based on the STRING online database.Gene ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analysis were conducted using Metascape online tool.The structures of the main active ingredients were obtained from PubChem database,the structures of core targets were obtained from RCSB PDB database,and then the structures were imported into Autodock for molecular docking.Finally,the mimic diagrams of the molecular docking were drawn using PYMOL software.Results A total of 12 active ingredients of Psoraleae Fructus were obtained,involving 274 targets.And there were 11 active ingredients and 98 targets associated with precocious puberty.The main active compounds were stigmasterol,bakuchiol,angelicin,bavachalcone,isobavachalcone,and xanthotoxin.The main targets were estrogen receptor 1(ESR1),estrogen receptor 2(ESR2),insulin-like growth factor 1(IGF1),and progesterone receptor(PGR),which were mainly involved in the ovarian steroidogenic pathway and Hippo signaling pathway.The molecular docking results showed that the active compounds were well binded to the targets.Conclusion It is possible that Psoraleae Fructus can promote the sexual development in children and has its potential pharmacological mechanism.The results will provide theoretical references for the clinical prevention and treatment of precocious puberty and early pubertal development in children.
