Ko 143 is a potent and selective ATP-binding cassette subfamily G member 2 (ABCG2/BCRP) inhibitor. Ko 143 displays >200-fold selectivity over P-gp and MRP-1 transporters.
体外研究
Ko143 (10 nM) significantly decreases (2.5-fold) the IC50 of MTX for HEK G2 cells and mouse G2 cells. Ko143 (1-100 μM) metabolite does not inhibit the function of ABC Transporters. Reversal of drug resistance in SKF 104864A-selected mouse MEF3.8/T6400 cells and human IGROV1/T8 cells by FTC analogue Ko143. Ko143 is applied at zero, one, or eight times the EC90 concentration of 25 nM. Ko143 inhibits BCRP-mediated transport of ZD 4522 in Madin-Darby Canine Kidney (MDCK) 2-BCRP421CC (wild type) cells and MDCK2-BCRP421AA (mutant type) cells.
体内研究
Ko143 (10 mg/kg, p.o.) increases the oral availability of SKF 104864A in mice. Ko143 significantly affects the pharmacokinetics of ZD 4522 in rats.
