Novel crystal forms of a kind of Sorafenib Tosylate and its production and use
Technical field
The present invention relates to medical technical field, particularly relate to novel crystal forms of a kind of Sorafenib Tosylate and preparation method thereofAnd purposes.
Background technology
Sorafenib Tosylate (SorafenibTsOH, molecular formula C28H24ClF3N4O6S, molecular weight 637.03) haveStructure shown in formula I, chemical name is 4-{4-[3-(the chloro-3-trifluoromethyl of 4-) uride] phenoxy group } pyridine-2-carboxamide is to firstBenzene sulfonic acid. By many target spots of one anti-cancer agent of German Bayer and Onyx exploitation listing (trade name: Nexavar, how luckyBeautiful). In December, 2005, Sorafenib Tosylate is ratified the line medicine as treatment advanced renal cell cancer fast through U.S. FDAThing Initial Public Offering. In June, 2006, Sorafenib Tosylate is used for the treatment of metastatic hepatic carcinoma indication and has obtained again FDAExamination & approval qualification fast. In August, 2009, state food and drug administration approval Bayer Bitterfeld GmbH drugmaker to tolueneSulfonic acid Sorafenib sheet formally enters Chinese market, for inoperable advanced liver cancer treatment.
Sorafenib Tosylate, as the oral anti-cancer agent of micromolecular many target spots, can not only suppress RAF-MEK-ERKPath, can also suppress the activity of the multiple receptor type tyrosine kinases such as VEGFR, PDGFR, Flt-3, C-Kit, thereby reachThe effect of inhibition tumor cell propagation and tumor angiogenesis.
The preparation side of Sorafenib Tosylate is disclosed in CN101052619, WO2009034308, US20130005980Method. CN101065360 discloses tri-kinds of crystal of I, II, III, the Sorafenib Tosylate first of Sorafenib TosylateAlcoholic solvent compound and alcohol solvent compound and corresponding preparation method. Wherein, polymorphic I is stable crystal form, and polymorphic IIBe metastable, be heated to 200 DEG C by polymorphic II, then be down to long-time stirring of room temperature with given pace and turn crystalline substance and obtain polymorphicI, is unfavorable for industry's enlarging production. It is a kind of with reflux in acetone acetonitrile mixed solvent salify, cooling that CN104177292A providesCrystallization, obtains the preparation method of polymorphic I Sorafenib Tosylate, and the method adopts mixed solvent, has increased in medicineThe possibility of dissolvent residual, although method is easy, what obtain remains polymorphic I.
The different polymorphics of a bulk drug can have different chemistry and physical characteristic, comprise fusing point, chemical reactivity, apparentSolubility, rate of dissolution, optics and engineering properties, vapour pressure and density. These characteristics can directly affect bulk drug and preparationProcessing and/or production, and can affect stability, solubility and the bioavilability of preparation. In the time there is polymorphic in compound,Because specific polymorph has specific macroscopic property and stability, therefore, in the process of preparation, understand in each agentThe crystal formation of the compound of applying in type is important, to ensure the pharmaceutical active compounds of process application same modality. Therefore,Keeping pharmaceutical active compounds is that single crystal formation or the known mixture of some crystal formations is necessary.
The discovery of the new polymorph of pharmaceutical active compounds provides the machine that improves medicine physical characteristic or prepare new formulationMeeting, has expanded whole character of material, and for example different polymorphs may have different solubility or pharmacokineticsMatter, can know the research of pharmaceutical active compounds and preparation thereof better. And in the time judging that whether which kind of crystal formation preferred,Much character and the preferred polymorph that must compare them make a choice based on many physical propertys. Completely possibleA kind of polymorphic in some aspects as difficulty or ease, the stability etc. of preparation to be considered under critical condition be preferred.
Therefore, Sorafenib Tosylate one water thing (SorafenibnTsOHmonohydrate, molecular formula provided by the inventionC21H16ClF3N4O3·nC7H8O3SH2O, molecular weight 464.82+172.20n+18.01) there is the structure shown in formula II, chemistryName is called 4-{4-[3-(the chloro-3-trifluoromethyl of 4-) uride] phenoxy group } polymorphic of pyridine-2-carboxamide p-methyl benzenesulfonic acid one hydrationThing has commercial value and researching value in the manufacture of medicine and application thereof.
