Network Pharmacology Identifies the Mechanisms of Sang-Xing-Zhi-Ke-Fang against Pharyngitis

Abstract EN

Background.

Sang-Xing-Zhi-Ke-Fang (SXZKF) demonstrates good therapeutic effect against pharyngitis.

Nevertheless, the pharmacological mechanism underlying its effectiveness is still unclear.

Objective.

To investigate the underlying mechanisms of SXZKF against pharyngitis using network pharmacology method.

Methods.

Bioactive ingredients of SXZKF were collected and screened using published literature and two public databases.

Using four public databases, the overlapping genes between these bioactive compound-related and pharyngitis-related genes were identified by Venn diagram.

Protein-protein interaction (PPI) was obtained using “Search Tool for the Retrieval of Interacting Genes (STRING)” database.

“Database for Annotation, Visualization, and Integrated Discovery ver.

6.8 (DAVID 6.8)” was used to perform Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis to explore the molecular mechanisms of SXZKF against pharyngitis.

Finally, Cytoscape 3.7.2 software was used to construct and visualize the networks.

Result.

A total of 102 bioactive compounds were identified.

Among them, 886 compounds-related and 6258 pharyngitis-related genes were identified, including 387 overlapping genes.

Sixty-three core targets were obtained, including ALB, PPARγ, MAPK3, EGF, and PTGS2.

Signaling pathways closely related to mechanisms of SXZKF for pharyngitis were identified, including serotonergic synapse, VEGF signaling pathway, Fc epsilon RI signaling pathway, Ras signaling pathway, MAPK signaling pathway, and influenza A.

Conclusion.

This is the first identification of in-depth study of SXZKF against pharyngitis using network pharmacology.

This new evidence could be informative in providing new support on the clinical effects of SXZKF on pharyngitis and for the development of personalized medicine for pharyngitis.
