Method: SwissTarget Prediction, Super PRED, and SEA databases were used to screen the targets of wogonin and chlorogenic acid, and GenCards and OMIM databases were used to search for CVA targets. Construct a “compound-target-disease” network by taking the intersection of these two clusters of gene targets. Constructing protein-protein interaction (PPI) network to screen core targets. Explore the biological pathways and signaling pathways involved in its action through GO and KEGG enrichment analysis. By molecular docking, the binding ability of wogonin and chlorogenic acid to core targets was verified, and their mechanism for treating CVA was preliminarily revealed. Result: 289 targets of wogonin and chlorogenic acid, 1957 targets of CVA, and 112 intersecting targets were retrieved. After constructing and analyzing the PPI network, 10 core targets were screened: PTGS2, EGFR, PPARG, MMP9, HIF 1α, NFKB1, TLR4, CCND1, MMP2, CREB1. GO functional enrichment analysis yielded 427 entries, while KEGG pathway enrichment analysis yielded 127 signaling pathways, including HIF-1 signaling pathway, PI3K-Akt signaling pathway, and IL-17 signaling pathway. Molecular docking showed that the binding energies of each combination were all below −5.0 kcal/mol, indicating that wogonin and chlorogenic acid could bind well to the core target. Conclusion: The combination of wogonin and chlorogenic acid can treat CVA through multi-target and multi-pathway, providing a theoretical basis for the study of wogonin and chlorogenic acid in the treatment of CVA.展开更多
