1. The inhibitory effects of tranylcypromine, a nonselective irreversible inhibitor of monoamine oxidase (MAO), on three cytochrome P450 (CYP) enzymes, namely CYP2C9, CYP2C19, and CYP2D6, have been evaluated in vitro. 2. The studies were conducted using cDNA-expressed human CYP enzymes and probe substrates. 3. A range of substrate concentrations was(More)
Dextromethorphan, a constituent of many over-the-counter cough syrups, is used as a probe drug for phenotyping subjects for their cytochrome P450 2D6 (CYP2D6) enzyme activity and for measuring CYP2D6 activity of preparations such as microsomes. In such studies, formation of the metabolite dextrorphan is used as indicator of the activity of this CYP enzyme.(More)
RATIONALE The selective serotonin reuptake inhibitor (SSRI) fluoxetine enhances some of the behavioural effects of cocaine, including locomotor stimulation. While this effect has often been interpreted as evidence for a serotonergic component to the behavioural effects of cocaine, direct evidence for this hypothesis is lacking. One alternative explanation(More)
An electron-capture gas chromatographic procedure was developed for detection and quantification of p-hydroxymephenytoin (OHMEP), a metabolite of S-mephenytoin, in human liver microsomal preparations. OHMEP was derivatized with pentafluorobenzoyl chloride (PFBC) under basic aqueous conditions prior to analysis on a gas chromatograph equipped with a(More)
