General description
CYP2C19 metabolite of mephenytoin.
Application
4-Hydroxymephenytoin has been used for developing ultra performance LC (UPLC)- tandem mass spectrometry (MS/MS) assays for evaluating cytochrome P450 (CYP) probe drugs and their relevant metabolites in human urine or plasma samples. 4-hydroxymephenytoin has also been used for developing sub-2-micron particle LC/MS/MS-based methods for analyzing CYP450 probe substrate metabolites.
Biochem/physiol Actions
4-Hydroxymephenytoin catabolism displays genetic polymorphism and is a direct indicator of Cytochrome P450 2C19 (CYP2C19) activity. Detection and quantification of 4-hydroxymephenytoin in biological samples by HPLC method is well optimized.
Packaging
Bottomless glass bottle. Contents are inside inserted fused cone.

The efficiency of drug metabolism by a single enzyme can be measured as the fractional metabolic clearance which can be used as a measure of whole body activity for that enzyme. Measurement of activity of multiple enzymes simultaneously is feasible

The preferential hydroxylation of (S)-mephenytoin to 4'-hydroxymephenytoin (4'-OH-M) displays a genetic polymorphism of drug metabolism in humans. Thus the excreted 4'-OH-M is considered to be an important marker for the hepatic (S)-mephenytoin 4'-hydroxylase. Accordingly, a mixture of urine containing total

To assess the possible relationship between the metabolic disposition of pantoprazole and genetically determined S-mephenytoin 4'-hydroxylation phenotype and genotype. The pharmacokinetic disposition of pantoprazole was investigated in 14 Japanese male volunteers (seven extensive and seven poor metabolizers of S-mephenytoin). All
