Objective The mechanism of wogonin against non-small cell lung cancer （NSCLC） was explored by network pharmacology，molecular docking and experimental verification. Methods The targets of wogonin were mined using the Traditional Chinese Medicine Database and Analysis Platform （TCMSP）and SwissTargetPrediction databases， and the targets related to NSCLC were retrieved from the GeneCards，TTD，and DrugBank databases. An intersection analysis was performed to identify shared targets，which were then analyzed for protein-protein interaction （PPI） using the STRING database. The Cytoscape software was utilized for visualization and topological analysis，and the key targets were screened. The clusterProfiler package in R software was used to conduct GO function annotation and KEGG pathway enrichment analysis. The AutoDockTools1.5.6 software was employed to verify the molecular docking between key targets and wogonin. In vitro experiments were conducted to investigate the potential mechanisms of wogonin against NSCLC predicted by network pharmacology. Results A total of 44 common targets of wogonin and NSCLC were obtained. Through PPI network analysis， Akt1， TP53， and JUN were the key therapeutic targets. GO function enrichment analysis revealed that the 44 common targets were primarily associated with the regulation of reactive oxygen species metabolic process， and protein kinase regulator activity. KEGG pathway enrichment analysis showed that the antiNSCLC activity of wogonin was related to the PI3K-Akt， IL-17， and p53 signaling pathways. Molecular docking results demonstrated that wogonin had good binding ability with Akt1，TP53，and JUN. In addition，cell experiments confirmed that wogonin treatment could effectively inhibit the proliferation，migration and invasion of A549 cells and promote apoptosis. Western Blot analysis showed that the expression levels of p-Akt， TP53 and JUN were downregulated after A549 cells were treated with wogonin （P＜0.05）. Conclusion Wogonin exerts anti-NSCLC effects by regulating PI3K-Akt， IL-17， p53 and other signaling pathways， and its mechanism of action is related to the regulation of Akt1，TP53，JUN targets.
