[ 1 ] - Effects of salidroside on rat CYP enzymes by a cocktail of probe drugs
Objective(s): In this study, we aimed to evaluate the effect of salidroside on the activities of the different drug-metabolizing enzymes CYP1A2, CYP2B6, CYP2C9, CYP2D6 and CYP3A4 in rats, in which a specific probe drug was used for each enzyme. Materials and Methods: After pretreatment with salidroside, five probe drugs were simultaneously administered to rats by gavage. The given dose was 2.0 ...
[ 2 ] - Evaluation of CYP2C9 activity in rats: use of tolbutamide alone and in combined with bupropion
A “cocktail”of several probe drugs is often used to evaluate metabolic activity of multiple cytochrome P450 enzymes in one session. Some interactions among probe drugs can appear and may impact the rate of biotransformation of other ones. Our presented work was to aim on the influence of bupropion on rat cytochrome P450-mediated metabolism of tolbutamide. The biotransformation rates of tolbutam...
