Abstract:

This study aimed to explore the mechanism of Clematidis Radix Rhizoma in the treatment of rheumatoid arthritis based on network pharmacology and molecular docking. Traditional Chinese medicine systems pharmaclogy database and analysis platform database, PubChem, and SwissTargetPrediction database were used to screen the active ingredients of Clematidis Radix Rhizoma and their targets. The targets of rheumatoid arthritis were predicted using OMIM database and GeneCards database. Venn diagram was used to obtain the intersection targets of Clematidis Radix Rhizoma and rheumatoid arthritis. Protein interaction network was constructed using STRING database and imported into Cytoscape3.7.1 to obtain core targets. DAVID database was used for Gene Ontology(GO) analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG) analysis. AutoDock Vina1.5.6 was employed to perform molecular docking of key active ingredients and core targets. The key active ingredients in Clematidis Radix Rhizoma, such as oleanolic acid, β-sitosterol, stigmasterol, and 3-epioleanolic acid, act on core targets, such as MAPK3, PTGS2, and CYP19A1, and play a role in the treatment of rheumatoid arthritis by regulating arachidonic acid metabolic pathway and ovarian steroidogenesis. The result of molecular docking suggested that the key active ingredients had good binding activity with the core targets. In this paper, the key active ingredients, core targets, and related pathways of Clematidis Radix Rhizoma in the treatment of rheumatoid arthritis were preliminarily discussed, serving as a reference for clinical application of Clematidis Radix Rhizoma.
