Metabolite Identification
Common NameTamoxifen-N-glucuronide
DescriptionTamoxifen-N-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. In other tissues such as the endometrium, it behaves as an agonist, and thus may be characterized as a mixed agonist/antagonist. Tamoxifen-N-glucuronide is an extremely weak basic (essentially neutral) compound (based on its pKa). tamoxifen-N-glucuronide and uridine 5'-diphosphate can be biosynthesized from tamoxifen and uridine diphosphate glucuronic acid through its interaction with the enzyme UDP-glucuronosyltransferase 1-4. In humans, tamoxifen-N-glucuronide is involved in tamoxifen action pathway. Tamoxifen-N-glucuronide is a metabolite of tamoxifen. 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.
