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.

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

Acquired resistance to third-generation EGFR tyrosine kinase inhibitors (TKIs) such as osimertinib (AZD9291) remains an unresolved clinical bottleneck in non-small cell lung cancer (NSCLC), with median progression-free survival plateauing at 18.9 months. This study evaluates CP, a novel curcumin-piperlongumine hybrid molecule, against AZD9291-resistant NSCLC using network pharmacology, molecular docking, and in vitro/in vivo validation. PPI network analysis of intersecting targets identified EGFR, SRC, PIK3R, PIK3CA, KDR, MET, GRB2, PIK3CB, HSP90AA1, and ITGB1 as core nodes, with KEGG enrichment converging on the PI3K/AKT signaling axis. Molecular docking confirmed hydrogen-bond-mediated binding between CP and these targets. Western blot analysis demonstrated that CP markedly suppressed phosphorylation of EGFR, PI3K, AKT, and GSK-3β. Functionally, CP arrested the cell cycle at G2/M and induced apoptosis in drug-resistant NSCLC cells, with enhanced potency relative to parent compounds curcumin and piperlongumine. In vivo xenograft experiments corroborated growth inhibition. The data position CP as a dual-pathway inhibitor targeting both EGFR and PI3K/AKT cascades, providing a mechanistic rationale for its development as a therapeutic candidate in EGFR-TKI-resistant advanced NSCLC. The unresolved question of whether GSK-3β inhibition operates independently of EGFR-AKT signaling warrants further investigation.
