Pregnanolone

Description:

Pregnanolone is a naturally occurring steroid and a neuroactive metabolite of progesterone, classified as a neurosteroid. It is characterized by its role in modulating the activity of neurotransmitter receptors, particularly GABA(A) receptors, which can influence mood, anxiety, and cognitive functions. Pregnanolone is a white crystalline solid at room temperature and is soluble in organic solvents such as ethanol and chloroform, but has limited solubility in water. Its molecular formula is C21H34O2, and it features a steroid backbone with a hydroxyl group, contributing to its biological activity. Pregnanolone is involved in various physiological processes, including the regulation of the menstrual cycle and the development of the central nervous system. Additionally, it has been studied for its potential therapeutic effects in conditions such as anxiety disorders and neurodegenerative diseases. Due to its neuroactive properties, it is of interest in pharmacological research, although its clinical applications are still being explored.

Controlled Product

CAS: 128-20-1

5b-Pregnan-3a-ol-20-one is a natural product that belongs to the group of steroids. It has been shown to inhibit the polymerase chain reaction in animals. The drug also inhibits pain and has been shown to be effective in models of epilepsy. 5b-Pregnan-3a-ol-20-one binds to DNA, preventing transcription and replication. It also stabilizes the surface of cells, which may be important for its uptake by cells. This compound interacts with Tlr4, which may activate immune cells and lead to seizures. 5b-Pregnan-3a-ol-20-one is oxidized by cytochrome P450 enzymes, leading to the production of hydrogen peroxide and formation of a carbonyl group on the molecule.
