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.
