Common Name | 4-Hydroxytamoxifen |

Description | 4-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 which is used for the potential treatment of menstrual-cycle related mastalgia, fibrocystic breast disease, breast disease, gynecomastia and keloid scarring. 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; which is mediated by the enzyme UDP-glucuronosyltransferase 1-4. In humans, 4-hydroxytamoxifen is involved in tamoxifen action pathway. 4-Hydroxytamoxifen is a potentially toxic compound. |
