Investigating of harmane, harmine, and norharman as inhibitors of MDR1 and MRP1 to overcome chemotherapy resistance in cancer cells
This study investigates the potential of harmane, harmine, and norharman as inhibitors of multidrug resistance (MDR) efflux pumps, MDR1 and MRP1, in cancer cells. These pumps are primary contributors to chemotherapy failure. Through molecular docking, cytotoxicity assays, and flow cytometry, the alkaloids demonstrated interactions with drug binding sites, enhanced chemosensitivity to daunorubicin, and inhibited drug efflux. Harmane, with its high lipophilicity, showed the strongest cytotoxicity, while harmine proved more effective in inhibiting efflux pump activity. While gene and protein expression effects were limited and inconsistent, the functional inhibition of these transporters highlights β-carboline alkaloids as promising candidates for combination therapy to overcome cancer drug resistance.

Enhanced Chemosensitivity in MDR Cell Lines
Co-treatment with beta-carboline alkaloids significantly reduced the IC50 of daunorubicin in both MDR1-overexpressing EPG85.257RDB gastric adenocarcinoma and MRP1-overexpressing A2780 ovarian adenocarcinoma cells. For EPG85.257RDB, daunorubicin IC50 decreased from 9.94 µM to 8.2 µM (harmane), 6.6 µM (harmine), and 7.8 µM (norharman). In A2780 cells, IC50 reduced from 1.75 µM to 0.81 µM (harmane), 0.79 µM (harmine), and 1.26 µM (norharman). This demonstrates their potential to reverse drug resistance.
