Product Description

Ko 143 is a potent and selective ABCG2 (breast cancer resistance protein multidrug transporter, BCRP) inhibitor (EC90 = 26 nM). It displays > 200-fold selectivity over P-gp and MRP-1 transporters. Ko 143 also increases intracellular drug accumulation and reverses BCRP-mediated multidrug resistance.
