Investigation on the Material Basis of Sijicao Granules in Treating Eczema Based on Network Pharmacology.

Objectives] To explore the pharmacodynamic material basis of Sijicao granules for the treatment of eczema through chemical com- position-network pharmacology. [Methods] First of all, the chemical constituents of Polygonum capitatum and Plantago asiatica from Sijicao granules were collected, and the relevant target information of the constituents was collected by TCMSP, PubChem, DisGeNET, GeneCards and STRING databases. Furthermore, Cytoscape 3.8.2 software was used to construct the chemical compounds-target network map of Sijicao granules. Finally, STRING database was used for PPI protein network analysis, GO functional enrichment analysis and KEGG pathway enrich- ment analysis of core targets, and molecular docking between core constituents and protein targets was also performed. [Results] 30 constitu- ents, including quercetin, kaempferol, luteolin, ellagic acid and gallic acid, were discovered to be the key effective compounds of Sijicao gran- ules in the treatment of eczema. And its core action protein targets were PTGS2, NOS2, AKTI, TP53, IL6, HMOX1. What's more, through GO functional enrichment analysis of biological process (BP), cell component (CC), molecular function (MF) analysis and KEGG pathway enrichment analysis, the main pathways of action of Sijicao granules for the treatment of eczema including IL-17 signaling pathway, T cell re- ceptor signaling pathway, cancer signaling pathway, TNF signaling pathway and Relaxin signaling pathway. In addition, molecular docking re- sults displayed that the primary active constituents quercetin, kaempferol and luteolin were well combined with the core protein targets AKTI and IL6. [Conclusions] Sijicao granules could play an important role for the treatment of eczema through multi-component, multi-target, multi-pathway and their interaction. [ABSTRACT FROM AUTHOR]
