摘要: 为了探究太子参抗心肌缺血的潜在作用机制,采用网络药理学方法对太子参的活性成分及心肌缺血的相关靶点进行预测,构建太子参抗心肌缺血的关键靶点网络,对其进行基因本体(gene ontologyGO)功能及Pathway富集分析,并将太子参活性成分与关键靶点进行分子对接验证。筛选获得太子参活性成分8个,对应的抗心肌缺血关键靶点50个。GO功能及Pathway富集分析显示:太子参抗心肌缺血主要参与细胞凋亡、血管新生及炎症反应等生物过程,涉及MyD88-independent TLR4 cascade(非依赖MyD88TLR4信号传导通路)、MyD88:Mal cascade initiated on plasma membraneMyD88:质膜上启动的MAL级联)及Activated TLR4 signalling(激活的TLR4信号通路)等,其中主要的作用靶点包括JUNMAPK1IKBKGPTPN11RELA等;分子对接验证蒲公英萜醇与关键靶点AKT1IL6MAPK1TP53的结合性最好。该研究揭示了太子参通过多途径、多靶点抗心肌缺血的作用机制,为进一步研究其抗心肌缺血作用提供了基础。

Abstract: To explore the potential mechanism of anti-myocardial ischemia of Pseudostellariae Radix, the active components and targets associated with myocardial ischemia were predicted using network pharmacology, and the key target network of anti-myocardial ischemia was constructed. GO(gene ontology) function and Pathway enrichment analysis were conducted, and molecular docking verification was performed between the active components and the key targets. Eight active components of Pseudostellariae Radix and 50 key targets of anti-myocardial ischemia were obtained. GO function and Pathway enrichment analysis showed that anti-myocardial ischemia effects of Pseudostellariae Radix were mainly involved in biological processes such as apoptosis, angiogenesis, and inflammation, including MyD88-independent TLR4 cascade (MyD88-independent TLR4 signal transduction pathway), MyD88:MAL cascade initiated on plasma membrane, and TLR4 signaling (activated TLR4 signal pathway). The main targets included JUN, MAPK1, IKBKG, PTPN11, and RELA. Molecular docking showed that dandelion terpenol had the best binding with the key targets AKT1, IL6, MAPK1 and TP53. The mechanism of anti-myocardial ischemia of Pseudostellariae Radix through multiple pathway and multiple targets was revealed in this study, which provides a basis for further study of the anti-myocardial ischemia effect of Pseudostellariae Radix.
