Description
Technical field
The present invention relates to field of medicaments, and in particular to a kind of shellfish is up to the purifying of quinoline free alkali and the preparation side of stable crystal form
Method.
Background technique
It is successfully a kind of novel biaryl quinolin class that shellfish, which is researched and developed up to quinoline (bedaquiline) by Johnson Co.,
Anti- mycobacteria drug, is clinically used for tuberculotherapy.Entitled (1R, the 2S) -1- of its chemistry (the bromo- 2- methoxyl group -3- quinoline of 6-
Base) -4- dimethylamino -2- (1- naphthalene) -1- phenyl -2- butanol, structural formula is as follows:
It is the unique antituberculosis new drug for ratifying listing in the late four decades that shellfish, which reaches quinoline,.Its fumarate system of Johson & Johnson
At oral solid formulation, trade name Si Nairui (Sirturo) is a kind of novel anti-mycobacteria medicine of biaryl quinolin class
Object, by inhibiting mycobacterium tuberculosis ATP to synthesize the activity of enzyme proton pump, to influence the ATP synthesis of mycobacterium tuberculosis, thus
Antibacterial and bactericidal effect are played, for treating adult Drug resistant pulmonary tubeculosis (MDR-PTB), is suitable for treating adult (>=18 years old) resistance to
Multi-drug resistance pulmonary tuberculosis.
Shellfish has same bactericidal activity to common and drug resistant M. tuberculosis strains up to quinoline, with existing treating tuberculosis
Drug is and equally effective to suspend mode bacterium without crossing drug resistant.China is that global tuberculosis bears most heavy one of country, tuberculosis sufferer
Person's quantity is more than 5,000,000 people, is only second to India, occupies the whole world second.The medicine can cope with tuberculosis for China, and this serious public is defended
Raw problem provides new therapeutic choice, is expected to improve the therapeutic effect of Drug resistant pulmonary tubeculosis, meets Drug resistant pulmonary tubeculosis patient and face
Bed Treatment need, reduces China's tuberculosis Disease Spectrum.
Shellfish, which reaches in quinoline molecule, 2 chiral centres, and synthesis technology is more complex, and technical process can generate multiple process impurities
And chiral isomer.The shellfish that shellfish is obtained at salt up to quinoline and fumaric acid up to quinoline fumarate in multi-solvents dissolubility compared with
Difference, impurity are difficult to remove by purification.Though patent CN106316943 reports shellfish up to quinoline fumarate process for refining
Road, but attempted according to the method for this report, purification yield is not high (60~80%), and refines the rear impurity content range of decrease not
Greatly.Therefore there is an urgent need to grope a kind of method for effectively purifying shellfish and reaching quinoline, the shellfish before making into salt reaches the Control of Impurities of quinoline
Reach the level of finished product.
Since shellfish is difficult to refine up to the fumarate of quinoline, consider to purify shellfish up to quinoline, make after its impurity qualification again at
Salt.According to the description for reaching quinoline free alkali separation method in patent CN200680017475 to shellfish, many experiments are attempted, and use ethyl alcohol
Mashing handles the shellfish to dissociate and reaches quinoline grease, and solid is precipitated and is easy agglomerating, unobvious, the purity of impurity removing before and after solid is precipitated
It is only shown by 96.5% raising to 97.1%, HPLC and is difficult to remove there are two major impurity.
Summary of the invention
The defect of quinoline purification technique is reached in view of existing shellfish, technical problem to be solved by the invention is to provide a kind of shellfishes to reach
The preparation method of the purifying crystal form of quinoline.By the method for the invention, the powdered crystal that shellfish reaches quinoline free alkali, dispersed is precipitated
State is good, and impurity removing effect is obvious before and after crystallization, and purity is improved by 96.5% to 99.7%, and single maximum contaminant content is reduced
To 0.1% hereinafter, having reached the quality standard of finished product.
We devise the experimental program of system, are touched by the condition of screening and purification process to multiple dicyandiamide solutions
Rope, we have surprisingly found that, are dissolved free shellfish out up to quinoline using suitable ketone, then suitable pure and mild purified water is added dropwise,
The powdered crystal that shellfish reaches quinoline free alkali is precipitated, dispersity is good, and it is obvious to remove effect for impurity before and after crystallization.
Shellfish of the present invention is as follows up to quinoline purification process:
1) shellfish of mixed is reached into quinoline and resolution reagent dinaphthol phosphate in organic solvent into salt, shellfish is then demultiplex out
Up to quinoline-dinaphthol phosphate ester salt；
2) it will split after obtained shellfish dissociates to fall resolution reagent up to quinoline-dinaphthol phosphate ester salt buck, be extracted with toluene
Take, be concentrated after obtain grease, ketone stirring and dissolving is added；
3) alcohol is added dropwise into solution, stirs, then pure water is added dropwise；Or pure water is first added dropwise into solution, it stirs, then be added dropwise
Alcohol；
4) it stirs, the powdered crystal that shellfish reaches quinoline free alkali is precipitated.
The ketone of dissolution grease is acetone, butanone, pentanone, cyclohexanone etc. in step 2), and ketone and Bei Da quinoline (reach quinoline by shellfish
Quinoline-dinaphthol phosphate ester salt meter) volume mass ratio be (1.5~3) ml/1g, the temperature of stirring and dissolving is 30~60 DEG C, preferably
50~60 DEG C.
The alcohol being added dropwise in step 3) is methanol, ethyl alcohol, isopropanol etc., and alcohol and Bei Da quinoline (reach quinoline-dinaphthol phosphorus by shellfish
Acid esters salt meter) volume mass ratio be (1.5~3) ml/1g.
The volume mass of the purified water and Bei Da quinoline (by shellfish up to based on quinoline-dinaphthol phosphate ester salt) that are added dropwise in step 3)
Than for (1.5~3) ml/1g.
In step 3), it is added dropwise and the temperature of whipping process is 30~60 DEG C, preferably 50~60 DEG C.
According to the method for the present invention, the stable shellfish purified reaches the crystal form feature of quinoline are as follows: its X-ray powder diffraction
The principal character peak of map 2 θ values be 4.78 °, 7.99 °, 10.38 °, 10.64 °, 11.21 °, 11.58 °, 13.02 °,
13.69°、15.22°、15.89°、18.14°、18.49°、19.42°、19.84°、20.48°、20.94°、22.10°、22.76°、
23.03°、24.18°、25.48°、26.68°、28.70°。
The present invention is that anti-tubercular drug of new generation --- shellfish provides a kind of efficient and convenient purification process, yield up to quinoline
Height, it is quality controllable.The method of the present invention is easy to operate, technique, up to quinoline purity is high, can reach into convenient for amplification production, resulting shellfish
Qualified shellfish can be obtained up to quinoline fumarate finished product at salt with fumaric acid (pharmaceutical grade) in the medicinal standard of product.And the shellfish reaches
The crystal form of quinoline proves that its stability is good by stability experiment, convenient for storage, convenient for carrying out the conjunction that shellfish reaches other salt of quinoline
At and research.
