Abstract:

This study aimed to investigate the mechanism of Ranunculi Ternati Radix in the treatment of tuberculosis based on network pharmacology. The active ingredients and related targets of Ranunculi Ternati Radix were screened using the Traditional Chinese Medicine System Pharmacology database and analysis platform. With the help of the GeneCards database to search disease targets, the intersections of active ingredient targets and disease targets are used as the predicted targets of Ranunculi Ternati Radix for tuberculosis treatment. A protein-protein interaction network diagram was constructed using the STRING database, and gene ontoeogy and Kyoto encyclopedia of gene and genomes(KEGG) enrichment analyses were performed for the overlapping genes. Finally, molecular docking verification between active ingredients and potential targets was performed using the AutoDock software. In total, 12 active compounds were selected from Ranunculi Ternati Radix. These active ingredients mainly act on the key targets of tuberculosis, including CASP3, CASP8, CASP9, BCL2, and BAX. KEGG results indicate that Ranunculi Ternati Radix may interfere with tuberculosis by regulating the apoptosis signaling pathway. The main components of Ranunculi Ternati Radix identified using molecular docking include stigmasta-4,6,8, vittadinoside, stigmasterol, stigmasterol glucoside, sitosterol acetate, and beta-sitosterol. These components were known to have obvious effects on BAX, CASP3, and CASP9. This study explored the active ingredients of Ranunculi Ternati Radix and corresponding potential targets when treating tuberculosis at the molecular level based on network pharmacology. Furthermore, the mechanism of action of Ranunculi Ternati Radix was verified.
