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 (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, 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.
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.

3β-Dihydroprogesterone (3β-DHP), also known as 3β-hydroxyprogesterone, or pregn-4-en-3β-ol-20-one (4-pregnenolone, δ 4-pregnenolone), is an endogenous steroid. [1] It is biosynthesized by 3β-hydroxysteroid dehydrogenase from progesterone .
Tetrahydrocortisol is a neurosteroid and has been found to act as a negative allosteric modulator of the GABA A receptor, similarly to pregnenolone sulfate. [ 2 ] [ 3 ] [ 4 ] See also
