Definitions
- the invention relates to the method characterized in the claim.
- the 17a ⁇ -hydroxy-D-homo-1,4-pregnadiene-3,20-dione is known to be an important intermediate for the synthesis of pharmacologically active D-homo-steroids (DE-A-23 14 592, DE-A-24 45 818 and DE-A-24 45 817). With the help of the method according to the invention, it is possible to make this connection much easier
- Procedure runs in the desired manner; because it is known that the microorganism Bacillus lentus ATCC 13805 is generally not suitable for the oxidation of 3 ⁇ -hydroxy- ⁇ 5 steroids to 3-oxo- ⁇ 4 steroids.
- the process according to the invention is carried out under the same fermentation conditions which are also used in the known microbiological ⁇ 1 dehydrogenation of steroids with the microorganism Bacillus lentus ATCC 13805.
- Suitable substrate solvents are, for example, methanol, ethanol, glycol monomethyl ether, dimethylformamide or dimethyl sulfoxide).
- the emulsification of the substrate can be effected, for example, by dissolving it in micronized form or in a water-miscible solvent (such as methanol, ethanol, acetone, glycol monomethyl ether, dimethylformamide or dimethyl sulfoxide) with strong turbulence in (preferably decalcified) water, which is the usual Contains emulsification aids.
- a water-miscible solvent such as methanol, ethanol, acetone, glycol monomethyl ether, dimethylformamide or dimethyl sulfoxide
- Fatty acid esters of polyglycols Fatty acid esters of polyglycols.
- suitable emulsifiers are the commercially available wetting agents Tegin (R) , Tween (R) and Span (R) .
- the optimal substrate concentration, substrate addition time and fermentation time depend on the structure of the substrate used and the type of microorganism used. As is generally required in the case of microbiological steroid conversions, these quantities must be determined in individual cases by preliminary tests as are known to the person skilled in the art.
- the culture broth is extracted 3 times with 20 l of methyl isobutyl ketone, the extract in a rotary evaporator at max. Concentrated 50 ° C under vacuum. This is followed by purification by chromatography on aluminum oxide.
