摘要: | 目的:研究桃仁-红花药对治疗股骨头坏死(ONFH)的作用机制。方法:采用网络药理学方法。以化合物口服利用度(OB)>30%和类药性(DL)>0.18为标准,通过中药系统药理学分析平台(TCMSP)、反向分子对接服务器(DRAR-CPI)、人类基因数据库(GeneCards)和在线《人类孟德尔遗传》数据库(OMIM)筛选桃仁-红花药对的活性成分及治疗ONFH的作用靶标。借助网络拓扑属性分析软件Cytoscape 3.6.0构建活性成分- ONFH靶标网络。结合STRING数据库构建靶蛋白相互作用网络,筛选连接度排名前5的靶蛋白,并利用分子对接服务器预测其与桃仁-红花药对活性成分的结合活性。利用生物学信息注释数据库(DAVID)对靶点基因本体(GO)生物过程和京都基因与基因组百科全书(KEGG)中代谢通路进行富集分析。结果:从桃仁-红花药对中筛选出活性成分44个,包括黄芩苷、槲皮素等,与ONFH相关的作用靶点78个,包括血管内皮生长因子(VEGF)、内皮细胞生长抑制因子(VEGI)、急性C反应蛋白(CRP)等。经分子对接服务器分析发现,桃仁-红花药对的活性成分与靶蛋白结合能力较强。经GO和KEGG通路富集分析发现,桃仁-红花药对治疗ONFH的生物过程与凋亡过程负向调节、核转录因子κB活动的正向调节等有关,主要通过调节分泌型糖蛋白信号通路、黑色素生成信号通路、VEGF信号通路、基底部细胞癌信号通路、腺苷酸活化蛋白激酶信号通路等发挥作用。结论:本研究初步明确了桃仁-红花药对治疗ONFH的主要靶标和通路,可为后续进一步研究其药理作用奠定基础。 |
ABSTRACT: | OBJECTIVE: To study the mechanism of Prunus persica-Carthamus tinctorius couplet medicine in the treatment of osteonecrosis of the femoral head (ONFH). METHODS: The network pharmacology was adopted. The active components of P. persica -C. tinctorius couplet medicine and ONFH target were screened through TCM systematic pharmacological analysis platform target (TCMSP), DRAR-CPI, hnuman gene database (GeneCards) and online medelian inheritance in man (OMIM) using oral availability of compounds (OB)>30% and drug like (DL)>0.18 as standard. Network topology attribute analysis software Cytoscape 3.6.0 was utilized to construct the active components-ONFH targets network. Target protein interaction network was established on the basis of STRING database, and top 5 target proteins in the list of connectivity were screened, and molecular docking server was used to predict the combination activity of active components from P. persica -C. tinctorius couplet medicine. The biological processes of target gene ontology (GO) and metabolic pathways in Kyoto encyclopedia of genes and genomes (KEGG) were enriched and analyzed by DAVID. RESULTS: A total of 44 active components were screened from P. persica -C. tinctorius couplet medicine, including baicalin, quercetin, etc., and 78 targets related to ONFH including VEGF, VEGI, CRP, etc. Through analysis of molecular docking server, binding activity of active components of P. persica -C. tinctorius couplet medicine to target protein was strong. GO and KEGG pathway enrichment analysis showed that biological process of P. persica -C. tinctorius couplet medicine for ONFH was related with negative regulation of apoptosis process and positive regulation of nuclear factor-κB transcription factor, mainly through regulating secretory glycoprotein signaling pathway, melanogenesis signaling pathway, VEGF signaling pathway, signaling pathway of basal cell carcinoma, adenosine-activated protein kinase signaling pathway. CONCLUSIONS: This study preliminarily validates the major targets and pathways of P. persica -C. tinctorius couplet medicine for ONFH, which lay a foundation for further study on their pharmacological action. |
