Exploring the antitumor effect of curcumin-piperlongumine hybrid molecule (CP) on EGFR-TKI-resistant non-small cell lung cancer using network pharmacological analysis and experimental verification.

EGFR-tyrosine kinase inhibitor (TKI) therapy is the most effective targeted therapy for non-small cell lung cancer (NSCLC). However, drug resistance remains a significant factor in the failure of lung cancer therapy. In the present study, we utilize network pharmacology, molecular docking, in vitro and in vivo experiments to explore the targets and biological mechanisms of CP, a novel curcumin-piperlongumine hybrid molecule, in EGFR-TKI-resistant NSCLC cells. The results reveal that CP exhibits enhanced biological activity compared to its parent compounds. CP can effectively inhibit cell proliferation by arresting cell cycle in the G2/M phase and inducing apoptosis. Mechanistically, CP-induced apoptosis is partially mediated by PI3K/AKT signaling pathway. These findings highlight the potential of CP as a promising therapeutic agent for EGFR-TKI-resistant lung cancer therapy.
