Description

General description

A cell-permeable estradiol derivative that acts as an estrogen antagonist and down-regulates estrogen receptors without affecting estrogen receptor-mediated progesterone receptor expression. Hence, it lacks estrogen agonist activity. Shown to be more effective than tamoxifen in reducing estrogen receptors in breast tumor cells. Suppresses the growth of MCF-7 xenografts in mice for twice as long as tamoxifen and delays tumor growth.

Please note that the molecular weight for this compound is batch-specific due to variable water content.
