Estra-5(10),9(11)-diene-3,17-dione, cyclic 3-(1,2-ethanediyl acetal)

Description:

Estra-5(10),9(11)-diene-3,17-dione, cyclic 3-(1,2-ethanediyl acetal) is a synthetic organic compound that belongs to the class of steroids, specifically a derivative of estradiol. This compound features a steroid backbone with a diene structure, indicating the presence of two double bonds in the cyclopentanoperhydrophenanthrene framework. The cyclic acetal formation suggests that it has a protective group that stabilizes the carbonyl functionalities at positions 3 and 17, which are characteristic of steroid hormones. The presence of the 1,2-ethanediyl acetal moiety indicates that it has been modified to enhance its stability or bioavailability. This compound may exhibit hormonal activity, potentially influencing biological processes related to estrogenic activity. Its unique structure may also confer specific pharmacological properties, making it of interest in medicinal chemistry and hormone replacement therapies. As with many steroid derivatives, its synthesis and application would require careful consideration of its biological effects and potential side effects.
