(17α)-17-Hydroxy-19-norpregna-4,6-dien-20-yn-3-one

Description:

(17α)-17-Hydroxy-19-norpregna-4,6-dien-20-yn-3-one, commonly referred to as a synthetic steroid, is characterized by its structural modifications that distinguish it from natural steroid hormones. This compound features a pregnane backbone with specific alterations at the 17α position, where a hydroxyl group is present, and a 20-yn-3-one functional group, indicating the presence of a triple bond and a ketone. Its unique configuration contributes to its biological activity, often related to its role in modulating hormonal pathways. The compound is typically used in research settings, particularly in studies involving steroidogenesis and hormonal regulation. Its CAS number, 31528-46-8, allows for precise identification in chemical databases. As with many synthetic steroids, it may exhibit varying degrees of potency and specificity in biological assays, making it a subject of interest in pharmacological research. Safety and handling precautions are essential due to potential hormonal effects and regulatory considerations surrounding steroid compounds.
