Mechanism of Jingfang Granules in relieving alcohol and protecting liver based on bioinformatics technology / 中国中药杂志

ABSTRACT

The present study explored the potential mechanism of Jingfang Granules in relieving alcohol and protecting liver by network pharmacology and molecular docking and verified the effects and related pathways by animal experiments. The active components of Jingfang Granules were retrieved from Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP). Targets of drugs and diseases were obtained from PubChem, Swiss Target Prediction and CTD. The common targets were uploaded to STRING to plot the protein-protein interaction(PPI) network. The core targets were screened out and the target organs were identified by Bio GPS and Metascape, followed by Gene Ontology(GO) analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analysis of common targets. The acute drunk mouse model was established and the effects of Jingfang Granules on serum ethanol level and the expression of proteins related to the phosphatidylinositol 3-kinase(PI3 K)/protein kinase B(Akt) signaling pathway in the liver tissue of mice were observed. A total of 187 active components of Jingfang Granules were obtained, including 47 common targets with alcoholic liver injury. GO enrichment analysis and KEGG pathway analysis showed that Jingfang Granules might play the role of relieving alcohol and protecting liver through the PI3 K-Akt signaling pathway. The drug-component-target and component-target-pathway networks revealed that the important active components of Jingfang Granules in relieving alcohol and protecting liver included quercetin, 5-O-methylvisamminol, glyasperin M, glyasperin B and hederagenin. Molecular docking showed that the active components had a good affinity with AKT1, EGFR, ESR1 and PTGS2. Experimental results showed that Jingfang Granules(15 and 10. 5 g·kg-1) could significantly reduce the content of serum ethanol in mice and up-regulate the protein expression ratios of p-PI3 K/PI3 K and p-Akt/Akt in the liver tissue. Jingfang Granules could relieve alcohol and protect liver through multi-component and multitarget, and the mechanism may be related to the activation of the PI3 K-Akt signaling pathway.
