Uses

4-Pregnen-17α,20β-diol-3-one (cas# 1662-06-2) is a derivative of 17α-Hydroxy Progesterone (H952330), which is a metabolite of Progesterone (P755900). It can also be used as an antagonist of cb1 receptor for therapeutic use.

Biochem/physiol Actions

17α,20β-Dihydroxy-4-pregnen-3-one, also known as maturation-inducing hormone (MIH) or DHP, is the most potent steroid for inducing final oocyte maturation in several species of fish. DHP as a progestin regulates spermiation, improves sperm motility and acts as a pheromone in male cyprinids.

Oxidation of 17α,20β- and 17α,20α-dihydroxypregn-4- en-3-ones, side products of progesterone biotransformation with recombinant microorganisms expressing cytochrome P-45017α

Progesterone biotransformation with recombinant yeasts Yarrowia lipolytica E129A15 and Saccharomyces cerevisiae GRF18/YEp5117α expressing bovine adrenocortical cytochrome P-45017α yielded 17α-hydroxyprogesterone and two diols, 17α,20β- and 17α,20α-dihydroxypregn-4-en- 3-ones. The oxidation of mixtures of the three steroids with chromic acid resulted in the cleavage of 17-20 bonds in the diols with the formation of androst-4-ene-3,17-dione. The biotransformation of pregn-4-ene-20β-ol-3-one by means of Y. lipolytica E129A15 was accompanied by the following reactions: the primary oxidation of these compounds to progesterone and the subsequent successive reactions of 17α-hydroxylation and 20α- and 20β-reduction. The results widen the possibilities of enzymatic and chemical modifications of steroids.
