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 and its 3β-sulfate, pregnenolone sulfate, like DHEA, DHEA sulfate, and progesterone, belong to the group of neurosteroids that are found in high concentrations in certain areas of the brain, and are synthesized there.
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.
In addition to oral progesterone, oral pregnenolone has also been found to act as a prodrug of allopregnanolone, [65] [66] [67] though also of pregnenolone sulfate. [ 68 ] In animal models of traumatic brain injury , allopregnanolone has been shown to reduce inflammation by attenuating the production of proinflammatory cytokines (IL-1β and TNF ...
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 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
Dehydroepiandrosterone sulfate, a major endogenous steroid sulfate. Note the steroid ester at the C3β position. Steroid sulfates are endogenous sulfate esters of steroids. [1] They are formed by steroid sulfotransferases via sulfation of endogenous steroids like cholesterol and steroid hormones. [1]
