| chemical properties | white solid |
| usage | estradiol (known as α-estradiol or 17 α-estradiol) is a biologically active estrogen in human breast cancer cells in tissue culture. 17-εstradiol and its selective receptor, er-x, are not part of a classical hormone/receptor endocrine system but of a system with important autocrine/paracrine functions in the developing and adult brain. 17-estradiol may have enormous implications for hormone replacement strategies at the menopause and in the treatment of such neurodegenerative disorders as alzheimer’s disease and ischemic stroke. |
| biological activity | endogenous estrogen receptor ligand (k i values are 0.2 and 1.2 nm for er α and er β receptors respectively). |
