Описание
Прегненолон (3β-hydroxypregn-5-en-20-one), also known as P5, is an endogenous steroid hormone. It is the precursor of the progestogens, mineralocorticoids, glucocorticoids, андрогены, and estrogens, as well as the neuroactive steroids. Он регулирует гонадотропную секрецию и дифференцировку вольфова протока., pregnenolone is biologically active in its own right, acting as a neurosteroid.
Like other steroids, pregnenolone consists of four interconnected cyclic hydrocarbons. It contains ketone and hydroxyl functional groups, two methyl branches, and a double bond at C5, in the B cyclic hydrocarbon ring. Like many steroid hormones, it is hydrophobic. Its esterified version, pregnenolone sulfate, is water-soluble.
Pregnenolone undergoes further steroid metabolism in one of three ways.
Pregnenolone can be converted to progesterone. The critical enzyme step is two-fold using a 3-beta-hydroxysteroid dehydrogenase and a delta 4-5 isomerase. The latter transfers the double bond from C5 to C4 on the A ring. Progesterone is the entry into the delta-4-pathway, resulting in production of 17-hydroxy progesterone and andros tenedione, precursor to test osterone and estrone. Aldosterone and corticosteroids are also derived from progesterone or its derivatives.
Pregnenolone can be converted to 17-hydroxy-pregnenolone by the enzyme 17α-hydroxylase (CYP17A1). Using this pathway, termed delta-5 pathway, the next step is conversion to dehydroepiandros terone (DH EA) using a desmolase. DH EA is the precursor of andros tenedione.
Pregnenolone can be converted to androsta-5,16-dien-3 beta-ol by 16-ene synthetase.
заявка:
Pregnenolone is a steroid hormone involved in the steroidogenesis of progesterone, mineralocorticoids, glucocorticoids, андрогены, and estrogens. As such it is a prohormone. Pregnenolone is a GABAA antagonist and increases neurogenesis in the hippocampus.

3.With the same function of corticosteroids anti-inflammatory.
