17α-Epiestriol (17-epiestriol, 16α-hydroxy-17α-estradiol or estra-1,3,5(10)-triene-3,16α,17α-triol) is the 17α-epimer of estriol, a minor hydroxylated estradiol metabolite and a selective estrogen receptor (ER) beta agonist. 17α-Epiestriol is described as a relatively weak estrogen, which is in accordance with its relatively low affinity for the ERα. 17α-Epiestriol has been found to be approximately 400-fold more potent than estradiol in inhibiting tumor necrosis factor α (TNFα)-induced vascular cell adhesion molecule 1 (VCAM-1) expression in vitro.

Sample Use Guides
Human umbilical vein endothelial cells (HUVEC) was used for activity evaluation. Human umbilical vein endothelial cells were preincubated with either 17-epiestriol (10, 30, 100, 300 pM and 1, 3, 10 nM) various concentrations for 48 h, and TNFalpha (10 ng/ml) was added to the culture media for the last 4 h. Following this, the cells were collected and total RNA was extracted. RNA was loaded on 1% agarose-formaldehyde gel, electrophoresed, and visualized under UV light after ethidium bromide staining.
