Abstract: This work explores the mechanism of mangiferin sodium salt(MF-Na)in the treatment of atherosclerosis(AS)based on network pharmacology, molecular docking and in vitro validation. The target of MF-Na was screened by TCMSP, STITCH, SWISS and SEA databases. OMIM, GAD and Genecards databases were used to screen out the related targets of AS disease.

Using Cytoscape 3.6.1 software, the relationship network of “compound target pathway disease was drawn and analyzed”. The screened target genes were analyzed by GO and KEGG, and the molecular docking was carried out by AutoDock Vina software to evaluate the screening targets. Finally, the contents of TNF-α, NF-κB, IL-6, CCL2 and CXCL1 in vitro were determined by enzyme linked immunosorbent assay(ELISA). The expression of NF-κB p65 and NF-κB P50 were detected by immunocytochemistry. 119 MF-Na related targets, 433 as related targets and 23 drug disease common targets were screened, and 46 pathways were enriched. Cell experiments showed that MF-Na could significantly reduce the expression of TNF-α、NF-κB. Levels of IL-6, CCL2 and CXCL1, and TNF-α/NF-κB/CCL2 pathway works. The potential targets of MF-Na were screened by network pharmacology, and it was found that MF-Na may be through TNF-α/NF-κB/CCL2 pathway to reduce the expression of inflammatory factors and play a role in the treatment of AS.
