- n. The metabolic activation of xenobiotic compounds into reactive, toxic compounds
Sorry, no etymologies found.
Blood leaving the liver is eventually distributed to all other areas of the body; however, much of the absorbed xenobiotic has undergone detoxication or bioactivation.
There are two types of metabolism - detoxification and bioactivation.
To characterise whether some selective serotonin reuptake inhibitor (SSRI) antidepressants reduce tamoxifen's effectiveness by inhibiting its bioactivation by cytochrome P450 2D6 (CYP2D6).
Steinkellner H, Rabot S, Freywald C, et al. Effects of cruciferous vegetables and their constituents on drug metabolizing enzymes involved in the bioactivation of DNA-reactive dietary carcinogens.
The cytochrome P450 (CYP) gene family catalyzes drug metabolism and bioactivation and is therefore relevant to drug development.
2 The bioactivation of tamoxifen to endoxifen is mainly catalysed by the cytochrome P450 isoenzyme 2D6 (CYP2D6) .2
