EQUILENIN Chemical Properties,Uses,Production
Uses
Estrogenic steroidal hormone isolated from urine of pregnant mares. Occurs naturally in the d-form. Not found in human urine. Component of conjugated estrogenic hormones. Estrogen.
Uses
Equilenin is a naturally occuring estrogenic steroidal hormone (1,2) isolated from urine of pregnant mares (3). Not found in human urine. Component of conjugated estrogenic hormones. Estrogen. This compound is a contaminant of emerging concern (CECs). Drinking water contaminant candidate list 3 (CCL 3) compound as per United States Environmental Protection Agency (EPA), environmental, and food contaminants.
Definition
ChEBI: Equilenin is a 3-hydroxy steroid that is estrone which carries two double bonds at positions 6 and 8. It is found in the urine of pregnant mare's and extensively used for estrogen replacement therapy in postmenopausal women. It has a role as a mammalian metabolite and an antioxidant. It is a 3-hydroxy steroid and a 17-oxo steroid.
Purification Methods
Crystallise (+)-equilenin from EtOH (solubility is 0.63% at 18o, 2.5% at 78o), aqueous EtOH or *C6H6 (Norite) and dry it in a vacuum. It sublimes on melting and at 170-180o/0.01mm. The acetate crystallises from MeOH with m 165-167o and [ ] D +71o (c 1, CHCl3). [Bachmann et al. J Am Chem Soc 62 824 1940, Beilstein 8 III 1522, 1523, 1525, 8 IV 1420.]
