Ethisterone Usage And Synthesis
Chemical PropertiesOff-White Powder
OriginatorLutocyclin,Ciba
UsesSynthetic progestogen; metabolite of Danazol; intermediate in the synthesis of Spironolactone
DefinitionChEBI: 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 Process0.5 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 FunctionProgestin
