Abstract
PURPOSE: Shenfu decoction has outstanding curative effects in the treatment of COVID-19. This study aimed to explore the material basis and molecular mechanism of Shenfu Decoction through network pharmacology and molecular mechanisms, to provide a research basis for clinical medication and clues for subsequent research. METHODS: The active components and targets of Shenfu decoction were searched in the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP), and the COVID-19-associated genes were collected using the Gene Cards platform. The target protein-protein interaction network map was constructed by mapping two genes, and the 'drug-active ingredient-target' network was constructed using Cytoscape software. The Gene Ontology (GO) function and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment of the mapping targets were analyzed. RESULT: < .05, GO function was enriched in 108 biological processes, 16 cell processes and 27 molecular processes. Sixty-three signaling pathways were enriched by KEGG, which can be divided into four types: viral infection pathways, signal pathways, biological process pathways and different disease pathways. The comparison of negative and positive prescriptions further reflects the positive effect of Shenfu decoction against COVID-19. Finally, the effective ingredients with the high degree were molecular docked with Mpro, Rdrp and Spro proteins to further confirm the intervention effect of Shenfu Decoction on COVID-19. CONCLUSION: Shenfu decoction played an important role in regulating the anti-virus process, regulating immunity, inhibiting inflammation and regulating apoptosis through the interrelated regulation mechanism of multi-components and multi-targets, to treat patients with severe COVID-19.
