Description
Technical field
The invention belongs to the fabricating technologies of steroid hormone drug, and in particular to prepare protein anabolic hormone medicine to a kind of
The method of object danabol.
Background technique
Danabol is a kind of protein anabolic hormone drug, has both androgenic effect, is clinically mainly used for burning
Wound, wound and aftertreatment, the treatment etc. of childhood dystrophy are also used for treatment alpastic anemia, chronic debilitating disease
The convalescence of disease and patient etc. that is long-term or widely applying cortex hormone of aadrenaline, market tool are big.
The conventional production methods of danabol are to extract Chinese yam saponin from Chinese yam plant, through protection, oxidation,
Cracking is eliminated, and the key intermediate acetic acid gestation diene alcohol ketone (abbreviation diene) of acquisition is raw material, through oximate, Beckmann rearrangement,
3 step such as sour water solution, which is reacted, is made Dehydroepiandrosterone Acetate, then by dehydroepiandros-sterone again through grignard reaction, basic hydrolysis, Ovshinsky oxygen
4 steps such as 1 change, DDQ dehydrogenation, which are reacted, is made danabol, and synthetic route is shown in attached drawing 1.Wherein Chinese yam saponin mentions
It takes, oxicracking, Beckmann rearrangement, acid, basic hydrolysis, the techniques such as DDQ dehydrogenation reaction, it is more to generate waste water, and it is not easy to handle, it is easily dirty
Contaminate environment；The Ovshinsky oxidation technology used in production need to use steam distillation, and water consume, energy consumption is high.Importantly, with open country
Raw Chinese yam plant resources are increasingly depleted, and artificial growth Chinese yam plant, also because of the increasingly rising of the planting costs such as artificial, chemical fertilizer,
Cause the production cost of saponin, diene to be doubled and redoubled, the production cost of danabol is caused substantially to increase with the market price
It is long, significant impact was produced to global danabol pharmaceutical market already.
According to the design feature of product danabol, particularly, there are three the preparations of danabol
Key point, first point is to convert α-CH for the 17th in raw material ketone group3With β-OH；Second point is double in the 4th upper introducing
Key；It is thirdly in the 1st upper introducing double bond.The method of most traditional production danabol is using double bond at 5
On Dehydroepiandrosterone Acetate be raw material, first upper introduce α-CH at 173With β-OH, then at 4 while 3 introducing ketone groups
Double bond is introduced, finally obtains danabol in 1 upper double bond that introduces, i.e. the scheme as shown in Fig. 1 of the present invention.In the application
The preparation method of another danabol is disclosed in the first invention CN201710754305 of people, specifically uses 17
α-CH is had been incorporated on position3Mestanlone with β-OH is raw material, double bromine Mestanlones is first formed at 1 and 4, then at 1
Danabol is obtained with 4 formation double bonds.
But this field still needs the preparation method of more excellent danabol.
Summary of the invention
And it is raw material that the solution of the present invention, which is the IDD for directly having formed double bond using 1 and 4, up at 17
Fall ketone group and introduces α-CH3With β-OH, a step obtains danabol.
Therefore, the present invention provides a kind of method for preparing danabol, and the method includes first nutrition being used to train
It supports base and one or more microorganism fungus kinds makes phytosterol that Isosorbide-5-Nitrae-androsadiendione be prepared after microbial fermentation i.e.
IDD, then using the IDD as raw material, in the presence of methyl-magnesium-halide, organic solvent and acid, in 17 introducing α-CH3With β-OH,
The danabol is prepared.
