Metabolite Identification
Common Name4-Hydroxytamoxifen
Description4-Hydroxytamoxifen, also known as 4-OHT or tamogel, belongs to the class of organic compounds known as stilbenes. These are organic compounds containing a 1,2-diphenylethylene moiety. Stilbenes (C6-C2-C6 ) are derived from the common phenylpropene (C6-C3) skeleton building block. The introduction of one or more hydroxyl groups to a phenyl ring lead to stilbenoids. 4-Hydroxytamoxifen is a drug. 4-Hydroxytamoxifen is a very strong basic compound (based on its pKa). Within humans, 4-hydroxytamoxifen participates in a number of enzymatic reactions. In particular, 4-hydroxytamoxifen can be biosynthesized from tamoxifen through the action of the enzyme cytochrome P450 2D6. In addition, 4-hydroxytamoxifen and uridine diphosphate glucuronic acid can be converted into 4-hydroxytamoxifen-O-glucuronide and uridine 5'-diphosphate through its interaction with the enzyme UDP-glucuronosyltransferase 1-4. In humans, 4-hydroxytamoxifen is involved in tamoxifen metabolism pathway. 4-Hydroxytamoxifen is a potentially toxic compound.
