Study on the mechanism of Gualou Xiebai Guizhi decoction (GLXBGZD) in the treatment of coronary heart disease based on network pharmacology.

ABSTRACT

BACKGROUND: This study aims to analyze the mechanism of Gualou Xiebai Guizhi decoction (GLXBGZD) in treating coronary heart disease (CHD) utilizing network pharmacology. METHODS: The GLXBGZD effective components were searched on the pharmacological database platform of the Traditional Chinese Medicine Systems Pharmacol, and its potential target was predicted. The Online Mendelian Inheritance obtained CHD disease target in Man and GeneCards database. The Venn map of the intersection target for GLXBGZD and CHD was constructed by using Venn online website. The "drug-component-target-disease" network map was constructed by Cytoscape 3.7.2 software. The DAVID online platform was used to analyze the function of Gene Ontology (GO) enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) at the intersection of targets of drugs and diseases. RESULTS: A total of 27 articles were searched for GLXBGZD, including 111 potential targets, 5521 disease targets, 100 drug and disease intersection targets. The core target network map shows that Interleukin (IL)-6, TNF, vascular endothelial growth factor (VEGFA), TP53, EGF, JUN, MAPK1, Catalase (CAT), and prostaglandin-endoperoxide synthase 2 (PTGS2) may be the key targets in CHD therapy. GO functional enrichment analysis revealed that the biological functions of GLXBGZD involved biological processes such as response to drugs, positive regulation of nitric oxide biosynthesis process, and response to hypoxia. KEGG pathway enrichment analysis showed that GLXBGZD might participate in CHD treatment through Hypoxia-inducible factor-1 (HIF-1), Tumor necrosis factor (TNF), PhosphoInositide-3 Kinase--Threonine protein kinase (PI3K-Akt), and the calcium signal pathway. CONCLUSIONS: This study reveals that the GLXBGZD mechanism in CHD treatment has the characteristics of multi-components, multi-targets, and multi-pathways, which provides a theoretical basis for its clinical application and subsequent experimental verification.
