摘要: 目的:系统研究新型冠状病毒肺炎一种预防方(湖北方,肺炎二号方)的主要化学成分,并结合网络药理学研究,为其药效物质研究提供一定的参考依据。方法:采用超高效液相色谱四极杆-飞行时间质谱联用仪(UHPLC-Q-TOF/MS)对该方剂的入血成分进行全面分析,采用TCMSP数据库、Swiss Target Prediction数据平台对鉴定得到的入血成分进行靶点预测,并运用网络可视化软件Cytoscape 3.7.2绘制关联网络图,最后对关键靶点进行GO富集分析和KEGG通路富集分析。借助CB-Dock在线分子对接平台对关键靶点与入血化合物进行分子对接,并利用Ligplot软件展示Affinity值较好的对接组合,以验证肺炎二号方对新冠肺炎的预防作用。结果:该方剂的体外化合物识别共有52个化学成分,其中入血成分13个,主要来自黄芪、麸炒白术、防风、金银花和陈皮。上述化合物作用于17个核心靶点,包括MAPK3、TNF等靶点与炎症有关,MPO等靶点与氧化应激有关,VEGFR、KDR等靶点与血管内皮有关。分子对接结果表明,入血化合物与关键靶点间具有较好的结合活性。结论:肺炎二号方中所含化合物通过参与调节炎症、氧化应激、血管和细胞生理等活动,调节IL-17、PI3K-Akt、MAPK等通路来发挥预防新冠肺炎功效。

Abstract: AIM: The main chemical components of Yufang Fangji II (Hubei Fang) of COVID-19 were studied systematically and combined with network pharmacology to provide a reference for the study of its effective substances. METHODS: Ultra high-performance liquid chromatography quadrupole time of flight mass spectrometry (UHPLC-Q-TOF/MS) was applied to identify the absorbed components of the prescription in rat plasma. TCMSP database and Swiss Target Prediction data platform were used to predict the target of the identified blood components, and network visualization software Cytoscape 3.7.2 was used draw the association network diagram, and GO enrichment analysis and KEGG pathway enrichment analysis were conducted for the key targets. With the help of CB-Dock online molecular docking platform, the molecular docking of key targets and blood entering compounds was carried out, and the docking combination with good affinity value was displayed by ligplot software to verify the preventive effect of Yufang Fangji II on COVID-19. RESULTS: A total of 52 chemical components identified in the prescription, in which 13 components were absorbed in the rat plasma as the prototype, and they were from Astragalus membranaceus, Atractylodes macrocephala, Saposhnikoviae Radix, Lonicerae Japonicae Flos, and Citri Reticulatae Pericarpium, respectively. These compounds were recognized to act on 17 core targets, including mapk3, TNF and other targets related to inflammation, MPO and other targets related to oxidative stress, VEGFR, KDR and other targets related to vascular endothelium. The results of molecular docking showed that the absorbed components had good binding activity with the key targets. CONCLUSION: Compounds in Yufang Fangji II are involved in regulating inflammation, oxidative stress, vascular and cellular physiological activities, which have preventive effects on COVID-19 through regulating IL-17, PI3K Akt, MAPK and other pathways.
