基于血清药物化学和网络药理学探讨通腑止血方治疗脑出血的药效物质和作用机制
Pharmacodynamic material basis and mechanisms of Tongfu Zhixue formula treating cerebral hemorrhage based on serum pharamcochemistry and network pharmacology
目的 基于超高效液相色谱串联四极杆静电场轨道阱质谱(UPLC-Q-exactive orbitrap MS)技术定性分析通腑止血方的入血成分,并结合网络药理学探究其治疗脑出血的潜在作用机制。 方法 通过对比含药血清、空白血清的色谱图,并结合数据库二级图谱、文献及对照品裂解信息,分析鉴定通腑止血方的入血成分。借助中药系统药理学数据库与分析平台(TCMSP)、Swiss Target Prediction、Comparative Toxicogenomics Database和Genecards数据库分别对入血成分、疾病进行靶点收集筛选,运用Cytoscape软件进行网络可视化处理,以中心度≥1 252.14、度值≥37.94为阈值筛选关键靶点,构建药材-入血成分-关键靶点图;取度值前10的靶点为核心靶点,对核心靶点进行京都基因与基因组百科全书(KEGG)通路富集分析和基因本体(GO)富集分析,运用Pymol软件对筛选出的度值前10的核心靶点与相联系的入血成分进行分子对接验证。 结果 共鉴定出14个原形成分,分别为人参皂苷Rf、人参皂苷Rb1、人参皂苷Rg1、人参皂苷F1、人参皂苷Rh1、三七素、槲皮素、柠檬酸、水杨酸、芦荟大黄素、大黄酸、大黄素、大黄酚和大黄素甲醚;关键靶点共111个,其中度值前10的核心靶点分别为PTGS2、IL-1β、TNF、CASP3、IL-6、HSP90AA1、Bcl-2、CYP3A4、RELA和AKT1。KEGG富集分析显示,核心靶点主要富集于TNF信号通路、IL-17信号通路及NF-κB信号通路。分子对接表明,除水杨酸和柠檬酸外,其他核心成分(如人参皂苷Rb1、大黄酸)与核心靶点结合能均≤-6.0 kcal/mol,其中大黄酸与HSP90AA1结合能达-10.4 kcal/mol。 结论 通腑止血方主要通过人参皂苷Rb1、人参皂苷Rg1、芦荟大黄素、大黄酸、大黄素、大黄酚和大黄素甲醚7个入血成分调控TNF、IL-1β、RELA、AKT1等核心靶点,从而抑制TNF/NF-κB炎症级联反应及凋亡通路,同时激活PI3K-Akt促存活信号,协同发挥抗炎、抗凋亡及血管修复作用。
Objective To qualitatively analyze the blood components of Tongfu Zhixue formula by ultra-high performance liquid chromatography tandem quadrupole electrostatic field orbit trap mass spectrometry(UPLC-Q-Exactive Orbitrap MS), and explore the potential mechanism of its treatment of intracerebral hemorrhage(ICH) by network pharmacology. Methods By comparing the chromatograms of medicated serum and blank serum, combined with database secondary spectra, literature, and reference substance lysis information, the absorbed components of Tongfu Zhixue formula were analyzed and identified. The target genes of absorbed components and diseases were collected and screened using databases such as Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP), Swiss Target Prediction, Comparative Toxicogenomics Database, and Genecards, and network visua⁃lization processing was performed using Cytoscape software. Key targets were screened using a threshold of centrality ≥1 252.14 and degree value ≥37.94, and then a medicinal material-blood-entering component-key target diagram was constructed. The top 10 targets by degree value were taken as the core targets, and analyzed by Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analysis and Gene Ontology(GO) enrichment analysis. The molecular docking of the top 10 core targets screened by degree value using Pymol software and their associated blood-entering components were verified. Results A total of 14 prototype components(absorbed without metabolism) were identified, including ginsenoside Rf, ginsenoside Rb1, ginsenoside Rg1, ginsenoside F1, ginseno⁃side Rh1, dencichine, quercetin, citric acid, salicylic acid, aloe emodin, rhein, emodin, chrysophanol, and physcion. A total of 111 key targets were identified, and the top 10 core targets by degree value were PTGS2, IL-1β, TNF, CASP3, IL-6, HSP90AA1, Bcl-2, CYP3A4, RELA, and AKT1. The core targets were mainly enriched in TNF signaling pathway, IL-17 signaling pathway, and NF-κB signaling pathway. Molecular docking indicated that, apart from salicylic acid and citric acid, the binding energies of other core components(such as ginsenoside Rb1, rhein) with core targets were all ≤-6.0 kcal/mol, and the binding energy of rhein with HSP90AA1 was -10.4 kcal/mol. Conclusion Tongfu Zhixue formula exerts its synergistic anti-inflammatory, anti-apoptotic, and vascular repair effects by inhibiting TNF/NF-κB inflammatory cascade and apoptotic pathways, activating PI3K-Akt pro-survival signaling pathway through seven absorbed components(ginsenoside Rb1, ginsenoside Rg1, aloe-emodin, rhein, emodin, chrysophanol, and physcion), which regulates core targets(e.g., TNF, IL-1β, RELA, AKT1).
