Based on network pharmacology and molecular docking technology to explore the mechanism of Panax notoginseng in the treatment of membranous nephropathy.

Objective: Based on network pharmacology and molecular docking technology to explore the mechanism of Professor Cao Enze 's application of Panax notoginseng in the treatment of membranous nephropathy. Methods: TCMSP database was used to obtain the effective components and corresponding target information of Panax notoginseng, and Gene Cards database was used to obtain the disease target genes of membranous nephropathy. The intersection targets of the two were taken and the Venn diagram was drawn. The STRING database was used to obtain the protein interaction relationship, and the PPI network diagram was constructed by Cytoscape 3.9.1 software to screen out the core targets of Panax notoginseng in the treatment of membranous nephropathy. GO function and KEGG pathway enrichment analysis were performed using the David database to obtain the potential pathway of Panax notoginseng in the treatment of membranous nephropathy. Finally, Autodock software was used to verify the molecular docking of the main active components of the drug with the core targets. Results: A total of 7 effective components such as quercetin, ginsenoside rh2, Mandenol and Stigmasterol were retrieved, and 127 potential targets of Panax notoginseng in the treatment of membranous nephropathy were screened out. By PPI network topology analysis, 23 core targets such as JUN, TP53, RELA, AKT1 and MAPK1 were screened out. GO functional enrichment analysis contained 703 biological processes, 55 cell components and 121 molecular functions, and KEGG signal pathway enrichment analysis enriched 171 signal pathways. The results of molecular docking showed that there was a strong binding ability between the main core targets and the main components of Panax notoginseng. Conclusion: Through network pharmacology, it is concluded that Panax notoginseng treats membranous nephropathy through multiple targets and multiple pathways, which provides a theoretical basis for subsequent basic research.
