Neurosteroid. Zuranolone, an example of a neurosteroid, used for the treatment of postpartum depression. Neurosteroids, also known as neuroactive steroids, are endogenous or exogenous steroids that rapidly alter neuronal excitability through interaction with ligand-gated ion channels and other cell surface receptors. [ 1 ][ 2 ] The term ...
Steroidogenic enzymes are enzymes that are involved in steroidogenesis and steroid biosynthesis. [2][3][4][5] They are responsible for the biosynthesis of the steroid hormones, including sex steroids (androgens, estrogens, and progestogens) and corticosteroids (glucocorticoids and mineralocorticoids), as well as neurosteroids, from cholesterol ...
Research has shown that 5α-reductase is the rate-limiting enzyme in neurosteroid synthesis, specifically in the conversion of progesterone to allopregnanolone, [35] low levels of allopregnanolone has been tied to depression, anxiety and schizophrenia.
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.

Allopregnanolone, a major endogenous inhibitory neurosteroid. Steroid ring system.. This is a list of neurosteroids, or natural and synthetic steroids that are active on the mammalian nervous system through receptors other than steroid hormone receptors.
Dehydroepiandrosterone (DHEA), also known as androstenolone, is an endogenous steroid hormone precursor. [4] It is one of the most abundant circulating steroids in humans. [5] DHEA is produced in the adrenal glands, [6] the gonads, and the brain. [7]
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]
Allopregnanolone is a naturally occurring neurosteroid which is made in the body from the hormone progesterone. [10][11] As a medication, allopregnanolone is referred to as brexanolone, sold under the brand name Zulresso, [6][12] and used to treat postpartum depression. [11][13][14] It is given by injection into a vein. [11][6] Side effects of ...
