| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

Obtaining of 11alpha-Hydroxyandrost-4-ene-3,17-dione from Natural Sterols.[Pubmed:28710634]
Methods Mol Biol. 2017;1645:259-269.
Two-step one-pot microbial transformation enables obtaining of valuable steroids that are difficult to produce chemically. Here we describe a method for obtaining 11alpha-hydroxyandrost-4-ene-3,17-dione (11alpha-HAD) from cheap and available natural sterols (phytosterols or cholesterol).11alpha-HAD is a primary adrenal steroid in mammals and also a key precursor in the syntheses of halogenated corticoids. Conventional routes for its obtaining are based on chemical synthesis, or microbial hydroxylation of androst-4-ene-3,17-dione (AD). AD in turn is produced primarily with microbial biotransformation of natural sterols by some actinobacteria.Consequent bioconversions of sterols using two microbial strains in one bioreactor vessel without separation and purification of AD provides high yield of 11alpha-HAD. At the first fermentation step, phytosterol is converted to AD with Mycobacterium neoaurum NRRL 3805B, or relative strains, to yield about 70% (mol/mol). At the second step, AD is almost fully (98%) hydroxylated at the position 11alpha with Aspergillus ochraceus VKM F-830, or other suitable organisms, in the same bioreactor. At the average, 30% (w/w) of the high-purity crystalline 11alpha-HAD can be obtained.The method can be exploited for production of 11alpha-HAD for practical use.
