Metabolite Identification
Common NameEndoxifen O-glucuronide
DescriptionEndoxifen O-glucuronide belongs to the class of organic compounds known as stilbene glycosides. Stilbene glycosides are compounds structurally characterized by the presence of a carbohydrate moiety glycosidically linked to the stilbene skeleton. Endoxifen O-glucuronide is a very strong basic compound (based on its pKa). Endoxifen O-glucuronide is a metabolite of tamoxifen. endoxifen O-glucuronide and uridine 5'-diphosphate can be biosynthesized from endoxifen and uridine diphosphate glucuronic acid through the action of the enzyme UDP-glucuronosyltransferase 1-10. In humans, endoxifen O-glucuronide is involved in tamoxifen action pathway. Tamoxifen is an antagonist of the estrogen receptor in breast tissue via its active metabolite, hydroxytamoxifen. 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.
