A network pharmacological analysis of Dracocephalum moldavica L. extract in the treatment of ulcerative colitis

Objective: To investigate the mechanism of action of Dracocephalum moldavica L. extract in the treatment of ulcerative colitis based on network pharmacology. Methods: The database was used to collect the target genes of Dracocephalum moldavica L. and ulcerative colitis. GO functional enrichment analysis and KEGG pathway enrichment analysis were performed on target genes through protein-protein interaction (PPI) network analysis and central topology screening. Results: A total of 172 potential targets for the treatment of ulcerative colitis with the active ingredients of Dracocephalum moldavica L. were obtained by searching the database. Meanwhile, the key therapeutic genes were screened by PPI network analysis, and the biological functions of the protein groups were analyzed for annotation. In addition, KEGG pathway enrichment analysis indicated multiple relevant pathways involved in digestion, immune system response and inflammatory response when Dracocephalum moldavica L. extract treating ulcerative colitis. Conclusions: The active ingredients in Dracocephalum moldavica L. extract have a variety of biological functions, which could act on sorts of inflammation, immune and cancer-related pathways for its multi-component and multi-target synergy.
