Network pharmacology and molecular docking reveal the mechanism of action of Bergapten against non‑small cell lung cancer

Non-small cell lung cancer (NSCLC) is a leading cause of cancer mortality worldwide, necessitating new treatment approaches with minimal side effects. In the present study, the potential of Bergapten (5-methoxypsoralen), a natural furanocoumarin compound, as a therapeutic agent against NSCLC was investigated by using network pharmacology, molecular docking and <i>in vitro</i> validation. Bergapten targets were identified using the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform and SwissTarget databases, whilst lung cancer-related targets were sourced from GeneCards and DisGeNET. Protein-protein interaction analysis and molecular docking were performed to identify key targets. The inhibitory effects of Bergapten on lung cancer cells were assessed using Cell Counting Kit-8 assays, wound healing assays, cell migration experiments, flow cytometry and western blotting. SC79 was used to verify the regulation of Bergapten on the PI3K/AKT pathway. Network pharmacology identified 51 targets, one signaling pathway and four Gene Ontology projects associated with the action of Bergapten against NSCLC. Key targets identified included glycogen synthase kinase-3β, Janus kinase 2, phosphatidylinositol-4,5-bisphosphate 3-kinase, catalytic subunit α and protein tyrosine kinase 2. <i>In vitro</i> experiments demonstrated that Bergapten significantly inhibited cell viability, promoted apoptosis, induced cellular senescence and inhibited the PI3K/AKT signaling pathway in NSCLC cells. In conclusion, Bergapten exerts its anti-NSCLC effects through the PI3K/AKT pathway, promoting cell senescence and inhibiting inflammation. These findings suggest that Bergapten has potential as a therapeutic agent for NSCLC.
