The synergistic mechanism of Vitiligo Capsule in treating vitiligo based on traditional Chinese medicine network pharmacology

OBJECTIVE To explore the active ingredients and action mechanism of traditional Chinese medicine preparation "Vitiligo Capsules" for vitiligo treatment based on traditional Chinese medicine network pharmacology.METHODS The active compounds and targets of Vitiligo Capsule in the treatment of vitiligo were collected by database search,kinetic parameter screening,literature mining and target prediction techniques.Cytoscape software was used to construct a "herb-compound-target" network diagram and perform topological analysis to explore key active ingredients.The STRING database explores protein interactions of potential therapeutic targets and analyzes core targets.The DAVID online enrichment analysis platform performs gene ontology(GO)and biological pathway(KEGG)functional enrichment of potential therapeutic targets.RESULTS A total of 133 compounds and 693 targets were collected from Vitiligo Capsules,of which 85 were potential vitiligo treatment targets.The results of network analysis showed that Quercetin,Luteolin,beta-sitosterol,Folcidin,Kaempferol,Shikonin,Baicalein,Folinic acid,Isorhamnetin,Isovitexin are important active ingredients.A total of 99 KEGG pathways,144 biological processes,19 cellular components,and 27 molecular functions were enriched using the DAVID platform.CONCLUSION "Vitiligo Capsules" exerts its effects through biological processes such as inflammatory response,positive regulation of T cell proliferation,negative regulation of apoptotic process and immune response.ATP binding,oxidoreductase activity,non-transmembrane protein tyrosine acid kinase activity and other molecular functions are involved.Besides,multiple signaling pathway are closely related,such as PI3K-Akt signaling pathway,MAPK signaling pathway,Toll-like receptor signaling pathway,tyrosine metabolism,Jak-STAT signaling pathway,apoptosis,NOD-like receptor signaling pathway,melanin production,phenylalanine metabolism and NF-κB signaling pathway.
