Biological Activity

Ko 143 is a potent and selective breast cancer resistance protein multidrug transporter (BCRP) inhibitor (EC 90 = 26 nM). Displays > 200-fold selectivity over P-gp and MRP-1 transporters. Increases intracellular drug accumulation and reverses BCRP-mediated multidrug resistance. Inhibits ABCB1 and ABCC1 at higher concentrations. Rapidly metabolized in rat plasma.
