描述 | Ko 143, a potent inhibitor specific to ATP-binding cassette subfamily G member 2 (ABCG2/BCRP), exhibits over 200-fold selectivity against P-gp and MRP-1 transporters[1][2]. At a concentration of 10 nM, Ko 143 notably reduces the IC50 of MTX for HEK G2 cells and mouse G2 cells by 2.5 times. However, Ko143 metabolites, ranging from 1-100 μM, do not affect the function of ABC Transporters[1]. The drug resistance reversal in Topotecan-selected mouse MEF3.8/T6400 cells and human IGROV1/T8 cells is achieved by the FTC analogue Ko 143, applied at 0, 1, or 8 times the EC90 concentration of 25 nM[2]. Ko 143 also blocks the BCRP-mediated transport of ZD 4522 in both wild type Madin-Darby Canine Kidney (MDCK) 2-BCRP421CC cells and mutant MDCK2-BCRP421AA cells[3]. |
Animal study | When administered orally at 10 mg/kg, Ko 143 enhances the bioavailability of SKF 104864A in mice and significantly alters the pharmacokinetics of ZD 4522 in rats[2][3]. |
