5-Oxo-hexahydroquinoline derivatives as modulators of P-gp, MRP1 and BCRP transporters to overcome multidrug resistance in cancer cells
Multidrug resistance (MDR) in cancer cells is often associated with overexpression of ATP-binding cassette (ABC) transporters, including P-glycoprotein (P-gp/ABCB1), multidrug resistance-associated protein 1 (MRP1/ABCC1) and breast cancer resistance protein (BCRP/ABCG2). Modulators of these transporters might be helpful in overcoming MDR. Moreover, exploiting collateral sensitivity (CS) could be another approach for efficient treatment of cancer.
