| Common Name | Endoxifen sulfate |
|---|
| Description | Endoxifen sulfate 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. Endoxifen sulfate is a very strong basic compound (based on its pKa). endoxifen sulfate and adenosine 3',5'-diphosphate can be biosynthesized from endoxifen and phosphoadenosine phosphosulfate through the action of the enzyme sulfotransferase 1A1. Endoxifen sulfate is a metabolite of tamoxifen. In humans, endoxifen sulfate is involved in tamoxifen metabolism pathway. In other tissues such as the endometrium, it behaves as an agonist, and thus may be characterized as a mixed agonist/antagonist. Tamoxifen is the usual endocrine therapy for hormone receptor-positive breast cancer in pre-menopausal women, and is also a standard in post-menopausal women although aromatase inhibitors are also frequently used in that setting. Tamoxifen is an antagonist of the estrogen receptor in breast tissue via its active metabolite, hydroxytamoxifen. |
