Description:

18,19-Dinorpregn-20-yn-3-one, 13-ethyl-17-hydroxy-, (5α,17α)-, commonly referred to by its CAS number 78088-19-4, is a synthetic steroid compound. It is characterized by a complex steroid structure, which includes a pregnane backbone with specific modifications at the 18 and 19 positions, as well as a triple bond at the 20 position. The presence of a hydroxyl group at the 17 position and an ethyl group at the 13 position further defines its chemical properties. This compound is often studied for its potential biological activities, particularly in the context of hormonal regulation and its effects on various physiological processes. Its stereochemistry, indicated by the (5α,17α) configuration, suggests specific spatial arrangements of atoms that can influence its interaction with biological receptors. As a steroid, it may exhibit lipophilic characteristics, allowing it to easily cross cell membranes and interact with intracellular targets. Overall, this compound is of interest in both pharmacological research and the study of steroid biochemistry.
