[Abstract]
Objective To explore the potential mechanism of Sanqifang Formula in the treatment of insomnia using network pharmacology and molecular docking technology. Methods The active ingredients of Sanqifang Formula and the potential targets were screened through the Traditional Chinese Medicine System Pharmacology Database and Analysis Platform (TCMSP), and the insomnia related targets were screened by GeneCards, OMIM and TTD databases, and the common targets were obtained by Venn diagram analysis. Cytoscape software was used to construct the PPI network, screen the core target proteins of Sanqifang Formula, and draw the drug-component-target network diagram to determine the main active components. Based on the common targets, Gene Ontology (GO) enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were performed to disclose the key pathways of the Sanqifang Formula in treating insomnia. For the purpose of further validating the analysis results, Autodock software was adopted for molecular docking verification.Results A total of 37 active ingredients and 233 potential targets were screened from four Chinese herbs (Ziziphi Spinosae Semen, Spatholobus Suberectus Dunn, Herba Cirsii and Panax Notoginseng), and 82 targets were shared with insomnia. According to PPI network analysis and drug-component-target network diagram, 29 active ingredients and 80 targets related to insomnia were screened. Among them, the key targets include interleukin-6 (IL-6), tumor necrosis factor (TNF), interleukin-1β (IL-1β), cellular tumor antigen P53 (TP53) and RAC-α serine/threonine protein kinase (AKT1). The core active ingredients were quercetin, stigmasterol, β-sitosterol and luteolin. A total of 77 signaling pathways were obtained by KEGG and GO enrichment analysis, which were mainly involved in molecular mechanisms such as inflammatory response, immune response, lipid metabolism, atherosclerosis, reactive oxygen species production, and apoptosis signaling pathway regulation. Molecular docking results showed that the core components had strong binding stability to the core targets and could play a role by regulating multiple key targets. Conclusion Sanqifang Formula has synergistic effect on insomnia through multi-component, multi-target and multi-pathway, and its anti-inflammatory effect and possible molecular mechanism deserve attention and further study.
