| Application: |
17α-Ethynylestradiol has been used to study the effect of exogenous estrogen and selective estrogen receptor modulator (SERM) in rats. It also has been used to increase the concentration of low density lipoprotein (LDL) receptor in rabbit liver. |
| Biochem/physiol Actions: |
17α-Ethynylestradiol is an orally bio-active synthetic estrogen used as an oral contraceptive. |
| General description: |
17α-Ethynylestradiol (EE2) is a synthetic hormone. It is a derivative of estradiol (E2). It is implicated in estrogen replacement therapy and suspension of breastfeeding. EE2 is used to treat osteoporosis, menopausal and postmenopausal syndrome. It is also used to treat prostatic cancer and breast cancer in postmenopausal women.
