Pregna-1,4,9(11)-triene-3,20-dione,21-chloro-17-[(2-furanylcarbonyl)oxy]-16-methyl-, (16a)- (9CI)

Description:

Pregna-1,4,9(11)-triene-3,20-dione,21-chloro-17-[(2-furanylcarbonyl)oxy]-16-methyl-, (16a)-, commonly referred to by its CAS number 83880-65-3, is a synthetic steroid compound. This substance features a complex steroidal structure characterized by a fused four-ring system typical of steroids, with specific functional groups that contribute to its biological activity. The presence of a chloro group and a furan moiety indicates potential reactivity and interaction with biological targets. The compound is likely to exhibit hormonal activity, given its structural similarity to natural steroid hormones, and may be involved in various physiological processes. Its unique configuration and substituents suggest potential applications in medicinal chemistry, particularly in the development of therapeutic agents. However, detailed studies on its pharmacokinetics, toxicity, and specific biological effects would be necessary to fully understand its characteristics and potential uses in clinical settings.
