Etynodiol, or ethynodiol, is a steroidal progestin of the 19-nortestosterone group which was never marketed.[1][2][3] A diacylated derivative, etynodiol diacetate, is used as a hormonal contraceptive.[1][2] Etynodiol is sometimes used as a synonym for etynodiol diacetate.

It was patented in 1955.[4]

Pharmacology

Etynodiol is a prodrug of norethisterone, and is converted immediately and completely into norethisterone.[5][6][7] Etynodiol is an intermediate in the conversion of the prodrug lynestrenol into norethisterone.[8]

Etynodiol is a 19-nortestosterone derivative. Structurally, it is almost identical to norethisterone and lynestrenol, differing only in its C3 substituent. Whereas norethisterone has a ketone at C3 and lynestrenol has no substituent at C3, etynodiol has a hydroxyl group at the position.
