(S)-MEPHENYTOIN Usage And Synthesis
Chemical PropertiesWhite Crystalline Solid
UsesS-Mephenytoin has been used as a CYP2C19 substrate for the analysis of cytochrome P450 metabolism. S-Mephenytoin has also been used as probe substrates for LC/MS-based analysis of relative activity factor (RAF).
Uses(S)-Mephenytoin can be used as an anticonvulsant agent.
DefinitionChEBI: (S)-Mephenytoin is an imidazolidine-2,4-dione.
Biological Activity(s)-mephenytoin is an anticonvulsive drug which is metabolized by n-demethylation and 4-hydroxylation (of the aromatic ring). (s)-mephenytoin is a substrate of the cytochrome p450 (cyp) isoform cyp2c19, also known as mephenytoin 4-hydroxylase [1].cyp2c19 is the main mephenytoin 4-hydroxylase in humans implicated in metabolizing a variety of therapeutic agents, such as omeprazole, proguanil, diazepam, propranolol, citalopram, imipramine, and certain barbiturates [2].
Biochem/physiol ActionsCYP2B6 & CYP2C19 substrate. Methenytoin isomer. Anticonvulsant; antiepileptic.
in vitroin the presence of cytochrome b5, the km value for s-mephenytoin was 1.25 mm with all five purified cytochrome p-450s preparations, and vmax values were 0.8-1.25 nmol of 4-hydroxy product formed per min/nmol of p-450 [1].
