Description About Ethisterone CAS:434-03-7 :

Ethisterone (INN, USAN, BAN) (brand names Pranone, Progestoral, Lutocylol, Proluton C, many others), also known as 17α-ethinyltestosterone, pregneninolone, or anhydrohydroxyprogesterone, is a steroidal progestin with androgenic activity which is derived from testosterone and was introduced for medical use in 1939.It was the second progestogen to be marketed (intramuscular progesterone was introduced as Proluton in 1934) and was both the first orally active progestogen and the first progestin (or synthetic progestogen) to be introduced.Although ethisterone has largely been superseded by newer drugs and is now little used, it continues to be available in some countries.Moreover, the 19-nortestosterone progestins, such as norethisterone, are derived from ethisterone and are widely used as hormonal contraceptives and for other indications.
