Objective To explore the potential mechanism of Erpixing Granules in treatment of infantile infantile anorexia by using network pharmacology and molecular docking. Methods The active components and corresponding targets in Erpixing Granules were retrieved from the TCMSP database. Infantile anorexia related target genes were obtained by searching GeneCards, OMIM, DrugBank, and TTD databases. The drug target and the disease target were intersected to obtain the effective targets of Erpixing Granules in treatment of infantile anorexia, and the drug disease Venn diagram was drawn. Cytoscape 3.9.0 software was used to construct a network diagram of drug-disease target interaction. The protein-protein interaction (PPI) network was constructed by using STRING database, and the network topology was analyzed. Through Bioconductor database and R language, GO and KEGG enrichment analysis of relevant targets were conducted to understand the possible biological processes and pathways of Erpixing Granules in reatment of infantile anorexia. Finally, molecular docking verification is carried out by using SYBYL-x2.0 software. Results 46 Active components and 236 drug targets of Epixing Granules were screened. A total of 1 372 targets related to anorexia were retrieved, and 118 targets were common between active ingredients and diseases. 13 Key targets such as JUN, RELA, TNF, IL, and PI3K-Akt were found to play an important role in treatment of infantile anorexia with Erpixing Granules. GO and KEGG enrichment analysis showed that 2 521 biological functions and 181 signaling pathways were involved in the potential targets. The results of molecular docking showed that the active compounds of Erpixing Granules had high binding ability to several key disease targets. Conclusion Erpixing Granules may play a multi-component, multi-target and multi-pathway mechanism by regulating JUN, RELA, TNF, IL, PI3K-Akt and other key targets, which provides reference for further mechanism research and clinical application.
