Pregnenolone sulfate, also known as pregn-5-en-3β-ol-20-one 3β-sulfate, is a naturally occurring pregnane steroid and a derivative of cholesterol. It is the C3β sulfate ester of pregnenolone. A closely related steroid is dehydroepiandrosterone sulfate (DHEA-S), which is the C3β sulfate ester of dehydroepiandrosterone (DHEA).
Pregnenolone, sold under the brand name Enelone among others, is a medication and supplement as well as a naturally occurring and endogenous steroid. [3] [1] [4] [5] [6] It is described as a neurosteroid and anti-inflammatory drug and was used in the treatment of rheumatoid arthritis and soft-tissue rheumatism in the 1950s and is no longer prescribed today, but remains available as a supplement.
Pregnenolone (P5), or pregn-5-en-3β-ol-20-one, is an endogenous steroid and precursor/metabolic intermediate in the biosynthesis of most of the steroid hormones, including the progestogens, androgens, estrogens, glucocorticoids, and mineralocorticoids. [1]
Pregnenolone sulfate (PS): pregn-5-en-3β-ol-20-one 3β-sulfate – GABA A receptor negative allosteric modulator, NMDA receptor positive allosteric modulator, sigma-1 receptor agonist, TRPM3 agonist, other actions; The following are proneurosteroids: Pregnenolone (P5): pregn-5-en-3β-ol-20-one – of pregnenolone sulfate
Pregnanolone, also known as 3α,5β-tetrahydroprogesterone (3α,5β-THP) or as 5β-pregnan-3α-ol-20-one, is a naturally occurring pregnane steroid and a derivative of progesterone.
A neurosteroidogenesis inhibitor is a drug that inhibits the production of endogenous neurosteroids.Neurosteroids include the excitatory neurosteroids pregnenolone sulfate, dehydroepiandrosterone (DHEA), and dehydroepiandrosterone sulfate (DHEA-S), and the inhibitory neurosteroids allopregnanolone, tetrahydrodeoxycorticosterone (THDOC), and 3α-androstanediol, among others.

It is made from pregnenolone, and is a positive allosteric modulator of the action of γ-aminobutyric acid (GABA) at GABA A receptor. [10] Allopregnanolone has effects similar to those of other positive allosteric modulators of the GABA action at GABA A receptor such as the benzodiazepines, including anxiolytic, sedative, and anticonvulsant ...
In the first step in the steroidogenic pathway, cholesterol is converted into pregnenolone, which serves as the precursor to the progestogens progesterone and 17α-hydroxyprogesterone. These progestogens, along with another steroid, 17α-hydroxypregnenolone , are the precursors of all other endogenous steroids, including the androgens ...
