Ethisterone Chemical Properties,Usage,Production
Description
Ethisterone is an orally bioavailable synthetic progestin and a derivative of testosterone (Item Nos. ISO60154 | 15645) that binds to progesterone and androgen receptors (EC50s = 23 and 23.1 nM, respectively, in yeast). Ethisterone (1 μM) downregulates progesterone receptors in MCF-7 cells.
Chemical Properties
Off-White Powder
Originator
Lutocyclin,Ciba
Uses
Synthetic progestogen; metabolite of Danazol; intermediate in the synthesis of Spironolactone
Uses
Ethisterone has been used as a component in Dulbecco′s modified eagle medium (DMEM) to culture the transfected COS-7 cell for transient transfection assay and?gene transfection assay.
Definition
ChEBI: A 17beta-hydroxy steroid that is testosterone in which the 17beta hydrogen is replaced by an ethynyl group. Ethisterone was the first orally active progestin and is a metabolite of danazol.
Manufacturing Process
0.5 part of δ5:6-17-ethinyl-androstendiol-(3:17) is dissolved in 10 parts of dry acetone, the solution is mixed with a solution of 1 part of tertiary aluminum butylate in 40 parts of absolute toluene and the whole is heated to boiling in a reflux apparatus for 21 hours. After the reaction mixture has cooled it is diluted with 100 parts of ether, the solution is washed with dilute mineral acid and with water, dried and the solvent is evaporated. In this manner there is obtained δ5:6-17-ethinyl-androstene-3-one-17-ol (ethisterone); MP: 270°- 272°C; it may be recrystallized from ethyl acetate.
Therapeutic Function
Progestin
General Description
Ethisterone is a?progestogen. It is a danazol derivative.
Biochem/physiol Actions
Ethisterone acts as a progestational agent. It is consumed by pregnant mothers to prevent miscarriage.
