Technical field
The invention belongs to chemical medicine, more particularly to a kind of pyrimidines and its is pharmaceutically acceptable Salt, stereoisomer, prodrug and solvate, preparation method, pharmaceutical composition and medical usage.Specifically, this hair It is bright to be related to some pyrimidine compounds and its pharmaceutically acceptable salt, stereoisomer, prodrug and solvate, preparation side Method, comprising the compound, its pharmaceutically acceptable salt, stereoisomer, prodrug and/or solvate (especially these The useful polymorphic of compound and salt) the pharmaceutical composition and compound and its pharmaceutically acceptable salt, three-dimensional different Structure body, prodrug and solvate are in preparation for treating by various different forms (activated mutant body and/or the resistant mutation bodily form Formula) EGFR mediate disease drug in purposes.
Background technique
Cancer is becoming the mankind " killer " the most fatal, and in recent years, China dies of the total population of cancer every year, approaches 2000000 people.Although the discovery of various therapy approach and drug brings hope to cancer patient, these routines are controlled Treatment is there are many drawbacks, and for example side effect is big, and therapeutic effect is bad, tumor post-operation recurrence, transfer etc..There is an urgent need to new treatments Technology solves the status of the low success rate for the treatment of of cancer.The Individual Chemotherapy and targeted therapy occurred recently gives lung cancer therapy band Hope newly is carried out.Tumor cells targeted therapy is chemical or biological based on passing through to the closely related key molecule of tumour growth Learn to do a kind for the treatment of method of section selective killing tumour cell.Targeted therapies have specificity high, and selectivity is strong, and poison is secondary Act on lighter feature.When targeted therapy and classic chemotherapy, radiotherapy or tumour immunity use in conjunction, curative effect can be greatly reinforced, Reduce postoperative recurrence.Neoplasm targeted therapy is rapidly developed in recent years, is the emerging field and not of oncotherapy Carry out development trend.
Protein tyrosine kinase (PTKs) is class protein enzyme, they can be catalyzed the junket ammonia in a variety of key proteins Thus phenolic hydroxyl group phosphorylation reaction on sour residue activates the bioactivity of functional protein.The letter of this process in the cell Highly important status is occupied in number conduction path, it adjusts a series of physiochemistries such as cell growth in vivo, differentiation, death Process.Protein tyrosine kinase functional disturbance can cause a series of intracorporal diseases of biology.Studies have shown that cancer more than half The activation of protogene and oncogene is all related to protein tyrosine kinase, and the unconventionality expression of protein tyrosine kinase can lead to cell Proliferation is adjusted and is got muddled, and then leads to tumour.In addition, the unconventionality expression of tyrosine kinase also with the invasion of tumour and turn It moves, the chemotherapy drug resistance of tumor neovasculature generation, tumour is closely related.Tyrosine kinase has become anti-tumor drug and grinds The critically important target spot that hair is.
EGF-R ELISA (EGFR) is a kind of receptor tyrosine protein kinase, belongs to one in erbB receptor family Kind transmembrane protein.
EGFR has regulated and controled the proliferation of cell, survival, adhesion, migration and differentiation, its overactivity in kinds of tumor cells Or continuous activation, such as lung cancer, breast cancer, in the cells such as prostate cancer.Conversion and growth of the abnormal activation of EGFR in tumour In play critical effect.Block EGFR activation be clinically proven for effective targeting therapy on tumor cellular processes it One.EGFR has expression in 50% NSCLC (non-compactness cell lung cancer) case.This becomes EGFR and its family member The leading candidate of targeted therapy.Gefitinib (gefitinib) and Tarceva (erlotinib) are that the first generation of EGFR is small Molecule inhibitor is mainly used for treating the drug of advanced NSCLC.Clinical effectiveness shows Gefitinib or Tarceva to about The asian ancestry NSCLC patient of 10% white man NSCLC and about 35% is effective in cure.Analysis shows majority has EGFR Activating mutations NSCLC patient is significantly higher than the NSCLC patient of EGFR wild type to the reactivity of EGFR- tyrosine kinase inhibitor (TKI).
But clinical research show many patients quickly (12-14 month) just to the micromolecular inhibitor drug of these EGFR Produce drug resistance, i.e. acquired resistance.Residue (gatekeeper residue) T790M that guards the gate mutation is outside EGFR 20 A catastrophe point in aobvious son, is to cause one of drug resistant main mechanism.It is ground for the inhibitor of new generation of these EGFR mutation Study carefully and is coming in be successful.Afatinib (Afatinib) is EGFR and human epidermal growth factor receptor 2 (HER2) Potent, the irreversible double inhibitor of tyrosine kinase.Other similar multiple target points, high activity, irreversible inhibitor, example Such as, Canertinib (canertinib) replaces Buddhist nun (Dacomitinib) also just in later phase clinical test up to gram.These are novel The irreversible inhibitor of the second generation has very strong inhibiting effect to the EGFR that L858R and T790M is mutated, to Gefitinib or strategic point There is significant curative effect in Lip river for the cancer patient that Buddhist nun has developed drug resistance.But these second generations EGFR mutant inhibitor pair Wild type EGFR (WT-EGFR) similarly has extremely strong inhibition.The verified inhibition to Wild type EGFR of clinical research It will lead to drug toxicity and side effect with most of patient, for example show as fash or diarrhea in human body.
Overcome the Side effect of second generation EGFR inhibitor, must just reduce to Wild type EGFR (WT-EGFR) Inhibiting effect.The EGFR inhibitor of a new generation should keep prominent to EGFR L858R activated mutant body, Exon19 missing activation Variant and T790M resistant mutants have stronger inhibition, while showing phase to WT-EGFR and other receptor tyrosine kinases To lower inhibiting effect.Such compound, which can be used for treating, EGFR L858R activated mutant body, Exon19 missing activation The treatment of the cancer patient of mutant, and to first generation EGFR inhibitor such as Gefitinib, Tarceva or Conmana The treatment of cancer patient through the EGFR-T790M resistant mutants that develop drug resistance, and do not have to worry the suppression of second generation EGFR mutant Preparation side effect as brought by Afatinib.
Present invention show it is many it is (one or more) to EGFR mutant there is high inhibitory activity, but to Wild type EGFR The pyrimidine compound of only relatively low inhibition.The compound of the present invention has preferable physicochemical properties and safety poison Property parameter.Such compound has preferably in the treatment of cancer for the drug-resistant mutation for having EGFR activated mutant body and/or EGFR Effect.
The present invention relates to certain pyrimidine compounds and its pharmaceutically acceptable salt, can be used for by certain variation patterns EGF-R ELISA (such as L858R activated mutant body, Exon19 missing activated mutant body and T790M resistant mutants) The treatment or prevention of the disease or the patient's condition that are mediated.Such compound and its pharmaceutically acceptable salt, stereoisomer, prodrug And solvate, it can be used for the treatment or prevention of many different cancers.The invention further relates to include the compound and its medicine Acceptable salt, stereoisomer, prodrug and solvate (the especially useful polymorphics of these compounds and salt) on Pharmaceutical composition, the compound preparation in useful intermediate and relate to the use of the compound and its pharmaceutically may be used What salt, stereoisomer, prodrug and the solvate treatment of receiving were mediated by the EGFR of activation and/or resistant mutant forms The method of disease.
