Cas no 797-58-0 (18,19-Dinorpregn-4-en-3-one,13-ethyl-17-hydroxy-, (17a)-)

18,19-Dinorpregn-4-en-3-one,13-ethyl-17-hydroxy-, (17α)- is a synthetic steroid derivative with a modified pregnane skeleton, featuring a 13-ethyl substitution and a 17α-hydroxy group. This structural configuration enhances its stability and bioavailability, making it suitable for specialized pharmaceutical or research applications. The compound's unsaturated 4-en-3-one moiety is characteristic of many bioactive steroids, suggesting potential interactions with steroid receptors or enzymes. Its precise pharmacological profile depends on further functionalization or context of use. The 13-ethyl group may influence metabolic resistance, while the 17α-hydroxy group could modulate solubility or binding affinity. This compound serves as a versatile intermediate for steroid synthesis or mechanistic studies.
