Analog of the fungal toxin fumitremorgin C. Potent and selective inhibitor of the breast cancer resistance protein multidrug transporter (BCRP, EC90=26nM). Highly effective for increasing the intracellular drug accumulation and reversing BCRP-mediated multidrug resistance yet has little activity against P-glycoprotein, multidrug resistance-associated protein (MRP1) and other known drug transporters. In mouse models Ko143 was able to restore the intracellular accumulation and abolish the directionality in net flux of dasatinib. It is a highly useful tool for the identification of drug transport processes in complex experimental systems.
