CAS 517-09-9: (+)-Equilenin

Description:(+)-Equilenin is a naturally occurring steroid and a member of the class of compounds known as estrogens. It is primarily derived from the urine of pregnant mares and is often used in hormone replacement therapy. The molecular structure of (+)-Equilenin features a phenolic hydroxyl group, which contributes to its estrogenic activity. This compound exhibits a unique stereochemistry, characterized by its specific optical rotation, which is crucial for its biological activity. As a synthetic derivative of equine estrogens, it is known for its ability to bind to estrogen receptors, influencing various physiological processes such as reproductive health and bone density maintenance. In terms of solubility, (+)-Equilenin is generally more soluble in organic solvents than in water, which affects its formulation in pharmaceutical applications. Safety and efficacy are critical considerations in its use, as with all hormone therapies, necessitating careful monitoring of potential side effects. Overall, (+)-Equilenin plays a significant role in both veterinary and human medicine, particularly in managing menopausal symptoms and other estrogen-related conditions.
