The Therapeutic Mechanisms of Huayu Quban Capsule in Treating Acne Vulgaris Are Uncovered Through Network Pharmacology and Molecular Docking.

Purpose: To uncover how the Huayu Quban (HYQB) capsule treats acne vulgaris (AV) through the use of network pharmacology and molecular docking technology.

Methods: The traditional Chinese medicine system pharmacology database (TCMSP) was used to identify the components and potential targets of HYQB capsule. Targets related to AV were identified by screening the GeneCards, Disease Gene Network (DisGeNET) and Online Mendelian Inheritance in Man (OMIM) databases. The protein-protein interaction (PPI) network between targets of active ingredients and AV targets was built using the STRING database. Cytoscape3.7.2 software was used to create the visualization network for the 'herb-component-target' and identify the key targets. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) were utilized for functional enrichment analysis of the primary targets. Subsequently, molecular docking technology was employed to confirm the interaction between key components and core targets.

Results: The technique discovered 50 different active substances and 270 associated therapeutic targets in the HYQB capsule as well as predicting 70 targets for treating acne vulgaris. Cytoscape hubba plug-in identified 19 key target genes, with the top 5 being TNF, IL1B, CCL2, SIRT1, IFNG, and IL10. Analysis of KEGG pathways revealed significant enrichment of immune-related pathways, including TNF and IL-17 signaling pathways, among the target genes. The HYQB capsule also involves lipid and atherosclerosis, Th17 cell differentiation, and the AGE-RAGE signaling pathway in diabetic complication signaling pathways. Molecular docking results showed that quercetin, luteolin, kaempferol, and wogonin, the core components of HYQB, had good binding ability with the first 4 core targets.

Conclusions: The HYQB capsule may have a synergistic effect on inhibiting sebaceous adipogenesis and sebum cell differentiation and play an effect on AV through anti-inflammatory and antioxidant effects of different signaling pathways.
