Webments established conditions for all substrates wherein the rate of metabolite formation was limited only by the concentra-tion of microsomal protein. Hepatic microsomal cytochrome P-450 concentrations were determined from the carbon mon-oxide difference spectrum of dithionite-treated microsomes assuming a value of 91 mM'crrf1 for the molar ... WebFor most substrates, multiple cDNA-expressed cytochrome P450 isoforms were found to catalyze the formation of the fluorescent product. However, among the combinations tested, rat CYP2D2 displayed high selectivity for AMMC demethylation (a substrate selective for CYP2D6 in human liver microsomes).
WebCytochrome P450 2C9 (CYP2C9) CYP2C9 is an enzyme that is responsible for breaking down (metabolizing) several of the drugs that are commonly used today. Some medications, such as celecoxib, warfarin, and phenytoin require CYP2C9 in order for the medication to be metabolized to forms that are not active and are more easily eliminated from the body.
