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 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
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.
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.

Pregnenolone acetate (brand names Antofin, Previsone, Pregno-Pan), also known as pregn-5-en-3β-ol-20-one 3β-acetate, is a synthetic pregnane steroid and an ester of pregnenolone which is described as a glucocorticoid and as a skin-conditioning and skin anti-aging agent.
5α-Dihydroprogesterone (5α-DHP, allopregnanedione, [1] or 5α-pregnane-3,20-dione) is an endogenous progestogen and neurosteroid that is synthesized from progesterone. [2] [3] It is also an intermediate in the synthesis of allopregnanolone and isopregnanolone from progesterone.
