General description

A non-tetrahydroisoquinoline BCRP specific inhibitor based on the anthranilic acid scaffold, that displays an IC50 of 1.39 µM in a Hoechst 33343 assay in stably transfected MDCK BCRP cells, which is ˜50-fold more potent than novobiocin (IC50 = 65 µM), and shows no effect towards other ATP binding cassette (ABC) transporters P-gp and MRP1 at up to a concentration of 10 µM. It is shown to be an allosteric inhibitor in enzyme kinetics assays in the presence of BCRP specific substrates pheophorbide A and imitanib, and does not lead to a decrease in cell viability up to a concentration of 10 µM.
