1 New insights into the P-glycoprotein-mediated effluxes of rhodamines. Rhodamines ATP binding cassette subfamily B member 1 Homo sapiens
2 The kinetic parameter, ka = VM/km, which is a measure of the efficiency of the P-gp-mediated efflux of a substrate was similar for almost all the rhodamine analogues tested. Rhodamines ATP binding cassette subfamily B member 1 Homo sapiens
3 Our conclusion is that the compounds of these two classes of molecules, anthracyclines and rhodamines, are substrates of P-gp and that their pumping rates at limiting low substrate concentration are similar. Rhodamines ATP binding cassette subfamily B member 1 Homo sapiens
4 The findings presented here are the first to show quantitative information about the kinetic parameters for P-gp-mediated efflux of rhodamine analogues in intact cells. Rhodamines ATP binding cassette subfamily B member 1 Homo sapiens
