5-pregnene-3B,20A-diol

Description:

5-Pregnene-3β,20α-diol, with the CAS number 901-56-4, is a steroid compound that is part of the pregnane family. It is characterized by a steroid nucleus, which consists of four fused carbon rings. This compound features hydroxyl (-OH) groups at the 3β and 20α positions, contributing to its biological activity and solubility properties. It is a naturally occurring metabolite in the biosynthesis of steroid hormones and is involved in various physiological processes. The presence of hydroxyl groups makes it more polar compared to other steroids, influencing its interaction with biological systems and its solubility in different solvents. 5-Pregnene-3β,20α-diol is of interest in pharmacology and biochemistry due to its potential roles in hormone regulation and its implications in health and disease. Its structural characteristics also make it a subject of study in the synthesis of other steroid derivatives.

20a-Dihydro pregnenolone

Controlled Product

CAS: 901-56-4

Pregnenolone is a steroid hormone that is synthesized in the adrenal cortex. It has been used as a diagnostic agent for detecting low levels of human chorionic gonadotropin (hCG). Pregnenolone interacts with the 3β-hydroxysteroid dehydrogenase, which is an enzyme involved in the conversion of pregnenolone to progesterone. The gene encoding this enzyme has been found to be mutated in patients with hydroxylase deficiency. Pregnenolone can also be converted into other hormones such as cortisol and androstenedione by various hydroxylases. This process may be inhibited by 20a-dihydroprogesterone, leading to increased concentrations of pregnenolone in the plasma.
