文摘基于超高效液相色谱-四极杆静电场轨道阱质谱(UPLC-Q-Exactive Orbitrap-MS)技术及网络药理学探讨化浊散结除痹方治疗痛风性关节炎(gouty arthritis,GA)的药效物质及潜在机制。采用UPLC-Q-Exactive Orbitrap-MS技术鉴定化浊散结除痹方药物成分,对其有效成分进行定性分析,共鉴定出化浊散结除痹方中184个有效成分;通过PharmMapper在线数据库筛选有效成分靶点897个,在OMIM、GeneCards、CTD等数据库获取GA相关的疾病靶点491个,进行韦恩分析后获得二者的交集靶点60个,通过Cytoscape平台构建“成分靶点-GA靶点”网络图,利用STRING数据库构建蛋白-蛋白互作网络,筛选出16个核心靶点,将核心靶点进行基因本体论(Gene Ontology,GO)与京都基因和基因组百科全书(Kyoto Encyclopedia of Genes and Genomes,KEGG)信号通路的富集分析,并构建“成分-靶点-通路”网络图,发现该方治疗GA的主要有效成分为酚类、黄酮类、生物碱类、萜类化合物,关键靶点有SRC、MMP3、MMP9、REN、ALB、IGF1R、PPARG、MAPK1、HPRT1、CASP1,通过GO分析发现其治疗GA主要涉及脂质反应、细菌反应、生物刺激的反应等生物过程,通过KEGG分析发现其治疗GA相关的通路有脂质和动脉粥样硬化、中性粒细胞胞外诱捕网、IL-17等。综上,该研究揭示了酚类、黄酮类、生物碱类、萜类化合物可能是化浊散结除痹方治疗GA的核心药效物质,其药效机制可能与SRC、MMP3、MMP9等靶点及脂质和动脉粥样硬化、中性粒细胞胞外诱捕网、IL-17等通路相关。
