Objective Explored the network regulation mechanism of Gualoupi Injection for the treatment of coronary heart disease and stable angina pectoris using network pharmacology. Methods Based on the selection principle of main components and main structural types, 19 compounds of Gualoupi Injection were determined as the research object. The potential targets of compounds were predicted through Swiss Target Prediction and TCMSP databases. The disease targets of coronary heart disease and stable angina pectoris were collected through GeneCards, DisGeNET, and OMIM databases. The drug targets and disease targets were intersected, and the "component- target" network was constructed by Cytoscape software. The protein-protein interaction network was constructed using string database, and the gene ontology (GO) function enrichment analysis and signal pathway analysis were carried out with the help of Omicsbean software and KEGG database. The activity of key components was verified by the H2O2-induced H9c2 cells injury model. Results 110 Disease targets of 19 compounds were screened, and 14 key targets including APDH, TNF, EGFR, MMP9, PTGS2, ACHE, REN, PPARG, F2, HSP90AA1, MMP2, IL-2, HMOX1, and FGF2 were obtained by analyzing the network topology parameters, which play a role in the treatment of coronary heart disease and stable angina pectoris by participating in the regulation of PI3K-Akt signaling pathway, platelet activation, renin-angiotensin system, apoptosis, TNF signaling pathway, and arachidonic acid metabolism, calcium signaling pathway and other signaling pathways. Conclusion Gualoupi Injection plays a therapeutic role on coronary heart disease and stable angina pectoris mainly through anti-inflammatory, protecting vascular endothelium, regulating oxidative stress, intervening renin angiotensin system and regulating energy metabolism.
