Webb1 dec. 1993 · Abstract. The present study identifies the specific human cytochrome P-450 (CYP) enzymes involved in hydroxylation leading to activation of the anticancer drug cyclophosphamide and its isomeric analogue, ifosphamide. Substantial interindividual variation (4-9-fold) was observed in the hydroxylation of these oxazaphosphorines by a … WebbTraductions en contexte de "prodrug results" en anglais-français avec Reverso Context : Subsequent administration of the prodrug results in β-lactamase catalysed hydrolysis of the prodrug at the target site with release of the active drug or unstable precursor.
