Abstract excerpt
To study whether an in-vitro model for three different genotypes of human CYP2C9*3 polymorphism would be useful for predicting the in-vivo kinetics of (S)-warfarin in patients with the corresponding genotypes, the intrinsic clearance (Cl(int) or Vmax/Km) for (S)-warfarin 7-hydroxylation obtained from recombinant human CYP2C9*1 [wild-type (wt)] and CYP2C9*3 (Leu359/Leu) expressed in yeast and the mixture of equal...
