Abstract
6-fluoro-9 alpha -hydroxyandrost-4 ene-3,17-diones, including the novel 6 alpha -isomer, are prepared by microbial degradation of the 6-fluoro- DELTA <4>-3- keto derivatives of sterols using a mutant microorganism selected from Arthrobacter, Bacillus, Brevibacterium, Corynebacterium, Mycobacterium, Microbacterium, Nocardia, Protaminobacter, Serratia and Streptomyces, esp. Mycobacterium fortuitum NRRL B-8119. The products are of use in the synthesis of 6-fluoro- corticoids.
Description
SPECIFICATION
Steroid bioconversion process and product
US Patent Specifications Nos. 4,029,549; 4,214,051 and 4,035,236 disclose the use of Mycabacterium fortuitum NRRLB-8119to make 9-hydroxy - 3 - oxo - 4 - pregnene - 20 - carboxylic acid (9 - hydroxybisnoracid), its methyl ester, and 9 - hydroxy - 4 androstene - 3,17 - dione, respectively.
According to the present invention, a 6 - fluoro - 9a hydroxyandrost - 4- ene - 3,17 - dione (6 - fluoro
HAD) is prepared by conversion of a 6 - fluoro - A4 - 3 ketone derivative of a sterol, e.g. one or more of cholesterol, sitosterol, stigmasterol and campesterol. This process is preferably conducted by use of
M. fortuitum NRRL B-8119. The invention also encompasses the use of mutants obtained from the genera of micro-organisms disclosed in US Patent
Specification No 4,029,549, i.e. Arthrobacter, Bacillus, Brevibacterium, Coryn ebacterium, Microbacterium, Mycobacterium, Nocardia, Protaminobacter,
Serratia and Strepomyces. The micro-organisms of these genera are all well known sterol-degraders.
The wild-type strains of these genera degrade sterols non-selectively to small molecular weight compounds, e.g. CO2 + H2O. Mutants can be made from these wild types by following the procedures disclosed in Example 1 of US Patent Specification No 4,029,549. This example discloses the preparation of
M. fortuitum NRRLB-8119.
6c-fluoro - HAD is a novel compound. The products ofthe invention are useful intermediates.
Mutants which are characterised by their ability to selectively convert 6 - fluoro - A4 - 3 - ketone derivatives of sterols having 17-alkyl side chains and accumulate 6 - fluoro - HAD in the fermentation beer can be obtained by mutating micro-organisms ofthe genera: Arthrobacter, Bacillus, Brevibacterium,
Corynebacterium, Microbacterium, Mycobacterium,
Nocardia, Protaminobacter, Serratia and Strep tomyces Mycobacterium fortuitum NRRL 8-8119 is described in U.S. Patent 4,029,549. M. fortuitum
NRRL B-8119 has been deposited in the permanent collection at the Northern Regional Research
Laboratory, U.S. Department of Agriculture, Peoria,
Illinois, U.S.A. It has been available to the public at least since issuance of the above-mentioned U.S.
patents disclosing the microbe. It should be understood that the availability of the culture does not constitute a license to practice the subject invention in derogation of patent rights granted with the subject instrument by governmental action.
6-Fluoro-HAD is useful as an intermediate in the synthesis of valuable corticoids. For example, by application of current technology as disclosed in the steroid literature, the fluoro-HAD derivatives can be transformed to the pharmacologically important steroids such as fluocinolone acetonide, fluocinonide, flurandrenolide, paramethasone, fluprednisolone.
Following are examples which illustrate the fermentation process of the subject invention. These examples are merely illustrative, and, thus, should not be construed as limiting. All percentages are by weight and all solvent mixture proportions are by volume unless otherwise noted.
Example 1 - Fermentation of 6P - F - Cholestenone
The biotransformation medium contains (per liter) Ucon, 8.0 g; Cerelose, 5.0 g; NH4CI, 3.0 g; CaCO3, 3.0 g; Na3 [citrate] 2H2O, 3.0 g; Tween 80, 2.0 g; soyf lour, 1.0 g; KH2PO4, 0.5 g; urea, 0.5 g and 6P-F cholestenone, 2.0 g in tap water with the pH adjusted to 7.0.Flasks containing 100 ml portions of this medium are innoculated with 10 ml of seed cultures ofM. fortuitum NRRL B-8119, grown at 28 in a medium containing (per liter) nutrient broth, 8.0 g; glycerol, 5.0 g; yeast extract, 1.0 g and Tween 80, 1.0 g in distilled water with the pH adjusted to 7.0. The cultures are then incubated at 28" for 336 hr on a rotary shaker. Following incubation, the mixture is extracted with an equal volume of CH3Cl2 and the product, 6ssfiuoro-HAD, is isolated from this extract using standard chromatography.
Example 2
Upon substituting 6 a-fluorocholestenone for 6p- fluorocholestenone in Example 1, there is obtained 6a-fluoro-9cr-hydroxy-AD.
Example 3
Upon substituting 6ss-fluorocholestenone in
Example 1 with a P-fluoroketone derivative of another sterol, e.g., sitosterol, stigmasterol, and the like, there is obtained 6ssfluoro-HAD. The sterols can be used singiy or in combination and in pure or crude form.
Example 4
By substituting a sterol-degrading microorganism from the generaArthrobacter, Bacillus, Brevibacterium, Coryn ebacterium, Microbacterium, Nocardia, Protaminobacter, Serratia, and Streptmyces, for
Mycobacterium fortuitum NRRL B-8119 in the process disclosed in U.S. Patent 4,029,549 for preparing
M. fortuitum NRRL B-8119, there are obtained mutant microorganisms which are characterized by their ability to selectively convert 6-fluoro-A4-3-ketone derivatives of sterols with a C-17 side chain and accumulate 6-fluoro-HAD as a product.
Example 5
Upon substituting Gp-fluorocholestenone in
Example 1 with a 6a-fluoro-A4-3-ketone derivative of another sterol, e.g., sitosterol, stigmasterol, and the like, there is obtained 6a-fluoro-HAD. The sterols can be used singly or in combination and in pure or crude form.
Example 6
By substituting the mutants obtained in Example 4 forM. fortuitum NRRL B-8119 in Examples 1 and 3, there is obtained 6ssfluoro-HAD.
Example 7
By substituting the mutants obtained in Example 4 forM. fortuitum NRRL B-8119 in Examples 2 and 5, there is obtained 6a-fluoro-HAD.
Example 8
The 6-fluoro-A4-3-ketone derivatives of sterols can be prepared by following the procedures disclosed in U.S. Patent 4,100,027.
1. A process for preparing a compound of the formula
**WARNING** end of DESC field may overlap start of CLMS **.
Claims (8)
1. A process for preparing a compound of the formula
which comprises cultivating a mutant microorganism selected from the generaArthrobacter,
Bacillus, Brevibacterium, Corynebacterium, Myco bacterium, Microb acterium, Nocardia,
Proaminobacter, Serratia and Streptomyces, the mutant being characterised by its ability to selectively convert the 6-fluoro-A4-3-ketone derivative of a sterol with a C-17 side-chain and accumulate 6-fluoro-HAD in the fermentation beer, in an aqueous nutrient medium, under aerobic conditions, in the presence of a 6-fluoro-A4-3-ketone derivative of a sterol with or without a C-17 side-chain.
2. A process according to claim 1, wherein the mutant is of the Mycobacterium genus and the sterol has a C-17 side-chain.
3. A process for preparing a compound as defined in claim 1, which comprises cultivating
Mycobacterium fortuitum NRRL B-8119 in an aqueous nutrient medium, under aerobic conditions, in the presence of a 6-fluoro-ss4-3-ketone derivative of a sterol with a C-17 side-chain.
4. A process according to any preceding claim, wherein the sterol is one or more of sitosterol, cholesterol, stimasterol and campesterol.
5. A process according to claim 4, wherein the sterol derivative is 6,3-fluorocholestenone.
6. A process according to claim 4, wherein the sterol derivative is 6c-fluorocholestenone.
7. A process according to claim 1, substantially as described in any of the Examples.
8. Gcr-Fluoro-Sa- hydroxyandrost-4- ene-3,17 dione.
