Objective To explore the related targets and pathways of improving hypoxia tolerance of Chebulae Fructus and its potential mechanism of action based on network pharmacology and molecular docking technology. Methods The active ingredients of Chebula Fructus were collected and the potential targets of active ingredients in Chebula Fructus were predicted by SwissTarget Prediction platform. Hypoxia-related genes were collected from Genecards and OMIM databases. After the intersection of the two,the protein-protein interaction(PPI)network system was established by STRING and Cytoscape programs, key genes with strong correlation were searched, and Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analysis were completed. The "TCM - active ingredients - key genes - pathways" network was further constructed,and the top 5 core genes and the top 5 core components ranking by degree values of the network were selected, and the docking verification of corresponding proteins and molecules were performed by AutoDock Tools and Pymol programs. Results A total of 30 potential active ingredients of Chebulae Fructus and 312 potential targets for improving hypoxia tolerance were collected. The key genes were TNF, IL-6,ESR1,Bcl-2,Caspase-3,ALB,HIF-1α,JUN,STAT3 and NF-κB1. KEGG enrichment analysis was used to obtain prostate cancer,AGE-RAGE signaling pathway in diabetic complications. HIF-1 signaling pathway,lipid and atherosclerosis,PI3K-Akt signaling pathway,and pathways in cancer. Molecular docking results showed that the core active ingredients of Chebulae Fructus were well combined with the core genes. Conclusion Chebulae Fructus can exert the activity of enhancing hypoxia tolerance through multi-target and multi-pathway. The mechanism in this study can provide theoretical basis for the application of improving hypoxia tolerance and drug development of Chebulae Fructus.
