Abstract
Crystal form of a kind of cyclin dependent kinase (CDK4＆6) inhibitor and preparation method thereof is provided.Specifically; 6 acetyl group, 8 cyclopenta 5 methyl 2 ((5 (base of piperidines 4) base of pyridine 2) amino) pyrido [2 is provided; 3 d] pyrimidine 7 (8H) ketone (formula (I) compound) II types crystallization and preparation method thereof; the crystallization has X ray powder diffractions as shown in Figure 1; it possesses good chemical stability and stability of crystal form; and using low toxicity, the recrystallisation solvent of low-residual, clinical treatment can be preferably applied to.
Description
The present invention relates to 6- acetyl group -8- cyclopenta -5- methyl -2- ((5- (piperidin-4-yl) pyridine -2- bases) amino) pyrido [2,3-d] pyrimidine -7 (8H) -one and its II crystal formations.Formula (I) compound that the method according to the invention is prepared can be used for the treatment of breast cancer.
Breast cancer is one of most common malignant tumour of women, high with the incidence of disease, has much invasion, but course advancement is slow, and Chinese population association 2010 year 2 month issues in Beijing on the 1st《Chinese mammary gland disease survey report》Report display, the death rate of China's urban area breast cancer increases 38.91%, breast cancer, which has become, threatens WomanHealth maximum disease, at present at least 156 kinds of breast cancer medicines for grinding and listing, wherein 68% is target therapeutic agent, and numerous studies find that tumour is unusual related to the cell cycle, and the mass mutation of mitogenic signals albumen and antimitotic signal protein defect cause Proliferative Disorders in tumour cell；Simultaneously all there is genomic instability (GIN) and genome unstability (CIN) in most of tumour, and these three basic cell cycle defects are all directly or indirectly caused by the out of control of CDKs.Cyclin dependent kinase (CDK, Cyclin Dependent Kinase) inhibitor is increasingly becoming popular target.
The a generation two generations CDK inhibitor developed at present is a lot, two generation medicines of greatest concern include the CDK4＆6 inhibitor PD-0332991 of Pfizer companies and Onyx companies joint development, its activity by suppressing CDK4＆6, suppress Rb phosphorylation, E2F-Rb compounds is detained in endochylema, block the startup of cell cycle.Clinical test results (NCT00721409) are shown, progresson free survival phase (the Progression-free survival of the patient of Letrozole single therapy, PFS) it is 7.5 months, and the patient of Letrozole and the treatment of PD-0332991 drug combinations then extends to 26.1 months its progresson free survival phase, FDA thinks that this is probably a kind of breakthrough cancer therapy drug after the term results of this medicine have been audited at the beginning of this significant advantage obtains extensive concern, 2013.
WO2014183520 discloses the CDK4＆6 inhibitor similar to PD-0332991 structures, inhibitory activity and high selectivity with significant CDK4＆6, including following compound：
But WO2014183520 does not further investigate the crystal form of the compound.It is as well known to those skilled in the art, the crystalline structure of medicinal active component often has influence on the chemical stability of the medicine, the difference of crystallization condition and condition of storage is likely to result in the change of the crystalline structure of compound, sometimes can also be along with the crystal formation for producing other forms.In general, unformed drug products do not have well-regulated crystalline structure, often with other defects, such as product stability is poor, and crystallization is thinner, and it is more difficult to filter, easily caking, poor fluidity etc..Therefore, it is necessary to improve each side's surface properties of above-claimed cpd, it would be desirable to which it is higher and possess the novel crystal forms of good chemical stability that crystal form purity is found in further investigation.
The content of the invention
The invention provides the new crystal form of 6- acetyl group -8- cyclopenta -5- methyl -2- ((5- (piperidin-4-yl) pyridine -2- bases) amino) pyrido [2,3-d] pyrimidine -7 (8H) -one (as shown in formula (I)).
The series of crystallization product that compound shown in formula (I) is obtained under different crystallization conditions, X- diffraction and DSC detections have been carried out to gained crystallized product, it was found that compound shown in formula (I) is under conventional crystallization condition, a kind of crystal formation having good stability can be obtained, we are called the crystallization of II types.The DSC collection of illustrative plates of II types crystallization in the application, which is shown in 294.42 DEG C, nearby has melting endothermic peak, X-ray powder diffraction collection is as shown in Figure 1, radiated using Cu-Ka, the X-ray powder diffraction collection represented with 2 θ angles and interplanar distance (d values), wherein in 5.84 (15.12), 6.16 (14.35), 10.75 (8.22), 12.56 (7.04), 12.96 (6.82), 16.25 (5.45), 17.24 (5.14), 18.97 (4.67), 20.22 (4.39), 21.74 (4.08), 22.99 (3.87), there is characteristic peak with 25.85 (3.44).
Present invention also offers prepare 6- acetyl group -8- cyclopenta -5- methyl -2- ((5- (piperidin-4-yl) pyridine -2- bases) amino) pyrido [2; 3-d] pyrimidine -7 (8H) -one the crystallization of II types method, methods described comprises the steps：
1) compound shown in any crystal formation or unformed formula (I) is added in appropriate solvent, add acid, add alkali after dissolved clarification, crystallization, the solvent is selected from the mixed solvent with water of any one or they that carbon number is less than or equal to 3 alcohols, ketone, nitrile；
2) filtering for crystallizing and wash, dry.
The acid is inorganic acid, preferably hydrochloric acid in preferred embodiments；The alkali is inorganic base, preferably sodium hydroxide or potassium hydroxide.
Step 1 in preferred embodiments) described in solvent be methanol, ethanol, isopropanol, acetone, acetonitrile or methanol/water, ethanol/water, acetone/water, acetonitrile/water, isopropanol/water；Preferred alcohol.
The method of recrystallization is not particularly limited, and can be carried out with common recrystallization operation method.For example, can with compound shown in raw material formula (I) after organic solvent heating for dissolving slowly cooling crystallization, after the completion of crystallization, through filtration drying, you can obtain required crystallization.Specifically, the crystalline solid of institute's leaching generally under reduced pressure, is dried in vacuo under 30~100 DEG C or so, preferably 40~60 DEG C of heating condition, and the effect of recrystallization solvent is removed with regard to that can reach.
Determined by differential scanning calorimeter (DSC), X- diffracting spectrums, crystal formation research has been carried out to compound crystalline solid shown in obtained formula (I), while the dissolvent residual crystallized to gained is detected.
The crystallization of compound II types is not contained or the only residual solvent containing lower content shown in formula (I) prepared by the method according to the present invention, meet the limitation requirement about medical product residual solvent as defined in NF, thus the crystallization of the present invention can use preferably as medicating active ingredients.
Research has shown that, the II types crystallization of compound shown in formula (I) prepared by the present invention has good stability under conditions of illumination, high temperature, high humidity, and grinding, pressure and it is heated etc. under the conditions of, stability of crystal form is good, it disclosure satisfy that the medicinal requirements of production and transport storage, stable processing technique repeats controllable, can adapt in industrialized production.
The X-ray powder diffraction collection of the crystallization of compound II types shown in Fig. 1 formulas (I).
The DSC collection of illustrative plates of the crystallization of compound II types shown in Fig. 2 formulas (I).
The present invention is explained in greater detail below with reference to embodiment, embodiments of the invention are merely to illustrate technical scheme, and non-limiting the spirit and scope of the invention.
