18,19-Dinorpregna-2,5(10)-dien-20-yn-17-ol, 13-ethyl-3-methoxy-, (17α)-(±)-

Description:

18,19-Dinorpregna-2,5(10)-dien-20-yn-17-ol, 13-ethyl-3-methoxy-, (17α)-(±)-, commonly known by its CAS number 799-43-9, is a synthetic steroid compound that exhibits characteristics typical of progestins. This compound features a steroid backbone with specific modifications, including a 20-yn-17-ol structure, which contributes to its biological activity. The presence of the methoxy group at the 3-position and the ethyl group at the 13-position are significant for its pharmacological properties. As a progestin, it is primarily involved in the regulation of reproductive processes and may be utilized in various hormonal therapies. The stereochemistry indicated by (17α)-(±)- suggests that the compound exists as a racemic mixture, containing both enantiomers. Its chemical stability, solubility, and interaction with hormone receptors are critical for its effectiveness in therapeutic applications. Overall, this compound is of interest in the fields of endocrinology and reproductive health, particularly in the development of contraceptives and hormone replacement therapies.
