CYP (Cytochrome P450)
.
CYP Substrate
Testosterone
Testosterone, a well known steroid hormone, is used in Cytochrome P450 (CYP) metabolism inhibition and CYP induction drug interaction studies. The metabolism of testosterone to its hydroxy form, 6β-hydroxytestosterone (6β-OH-T) is a commonly used assay to evaluate human CYP3A enzyme activities.
Reaction in vivo
Conversion of testosterone to 6β-hydroxytestosterone reaction is used to determine enzyme activity of CYP3A4.
Example
It is used as a substrate for pharmacokinetics experiments to add to a cell together with a candidate compound that can be a drug and confirm whether it affects drug metabolism.
