Estriol is an antagonist of the G-protein coupled estrogen receptor in estrogen receptor-negative breast cancer cells.Target: Estrogen Receptor/ERRA recent study shows that estrogen (estrone, estradiol, and estriol) inhibits Alzheimer's disease-associated low-order Aβ oligomer formation, and among them, estriol shows the strongest in vitro activity [1]. In mPTEN+/- mice, estriol treatments resulted in a 187.54% gain in the relative ratio of uterine wet weight to body weight; estriol also

Estriol is a 3-hydroxy steroid that is estra-1,3,5(10)-trien-3-ol substituted by additional hydroxy groups at positions 16 and 17 (16alpha,17beta-stereoisomer). It has a role as an estrogen, a human metabolite, a human xenobiotic metabolite and a mouse metabolite. It is a 3-hydroxy steroid, a 16alpha-hydroxy steroid and a 17beta-hydroxy steroid. It derives from a hydride of an estrane.|A hydroxylated metabolite of estradiol or estrone that has a hydroxyl group at C3-beta, 16-alpha, and 17-beta position. Estriol is a major urinary estrogen. During pregnancy, large amount of estriol is produced by the placenta. Isomers with inversion of the hydroxyl group or groups are called epiestriol. Though estriol is used as part of the primarily North American phenomenon of bioidentical hormone replacement therapy, it is not approved for use by the FDA or Health Canada. It is however available in the United States by prescription filled only by compounding pharmacies. It has also been approved and marketed throughout Europe and Asia for approximately 40 years for the treatment of post-menopausal hot flashes.|A hydroxylated metabolite of ESTRADIOL or ESTRONE that has a hydroxyl group at C3, 16-alpha, and 17-beta position. Estriol is a major urinary estrogen. During PREGNANCY, a large amount of estriol is produced by the PLACENTA. Isomers with inversion of the hydroxyl group or groups are called epiestriol.
