Description
Technical field
The present invention relates to the pharmaceutical field of tumour.Specifically, the present invention relates to the tyrosine kinase inhibitor, its preparation method that the medicative class of above-mentioned disease tool are replaced to structure containing novel Benzoquinazole and ortho position fluorine, and at pharmaceutical applications.
Background technology
Tumour is one of principal disease of serious threat human life and quality of life, and according to WHO statistics, the patient about 6,900,000 of tumour is died from the whole world every year.Due to the change of living environment and life habit, under the effect of poor environment and some unfavorable factors, the M & M of tumour is in recent years in quick ascendant trend.
One of maximum family of protein kinase composition people fermentoid, and regulate many different intracellular signaling processes by adding on phosphate group to protein.Especially, tyrosine kinases phosphorylate protein is at the phenol moieties of tyrosine residues.Family tyrosine kinase comprises the member controlling Growth of Cells, migration and differentiation.Abnormal kinase activity has related to many human diseasess, comprises cancer, autoimmune disease and inflammatory diseases.Because protein kinase belongs to the key regulator of cell signaling, they provide the target regulating cell function with small molecule kinase inhibitors, and therefore become good medicinal design target.Except the treatment of kinase mediated lysis, the selectivity of kinase activity and effective inhibitor also can be used for studying cell signaling processes and identifying that other has the cell target of therapeutic potential.
The treatment of tumour was realized by finding tumour and destroying in the past, now along with deepening continuously of studying cell signaling pathway, people to the effect of the oncogene of inside tumor cells and antioncogene understand more and more deep, the antitumor drug new for the specific molecular shot design of tumour more and more receives publicity, become the hot fields of research, and anti-tumor drugs targeting has also been applied to clinical as a kind of new methods for the treatment of, and obtain significant progress in recent years.Now known, protein tyrosine kinase (Proteintyrosinekinases, PTK) propagation of signal path and tumour cell, differentiation, migration and apoptosis have substantial connection, utilize ptk inhibitor to disturb or block Tyrosylprotein kinase path to may be used for oncotherapy.PTK is the member in the cancer protein and proto-protein family played an important role in normal and abnormality proliferation process, it is a kind of a kind of enzyme that optionally can make the tyrosine residues phosphorylation of different substrate, γ-the phosphate of their catalysis ATP is transferred on the tyrosine residues of many key proteins, makes phenolic hydroxyl group phosphorylation.Protein tyrosine kinase is divided into receptor tyrosine kinase (receptortyrosinekinase, RTK), (the RobinsonD.R. such as nonreceptor tyrosine kinase and IR and Janus kinases, etal, Oncogene, 2000,19,5548-5557), wherein majority is receptor type tyrosine kinase (RTK).RTK is that a class has intrinsic protein tyrosine kinases, participates in the regulation and control of various kinds of cell activity, has extremely important status, regulate and control the Proliferation and differentiation of cell in the conduction of the mitogenesis signal copied at active cell.All RTK belong to I type membranin, and its molecule has similar topological framework: an outer ligand binding domain of large glycosylated born of the same parents, a hydrophobic single pass transmembrane district, and an intracellular tyrosine kinase catalyst structure domain and regulating and controlling sequence.The combination (as Urogastron (EGF) and the combination of EGFR) of part causes the kinase activation of code segment in recipient cell to activate, make the key tyrosine phosphorylation in target protein, cause proliferation signals to cross over cytoplasmic membrane transduction.
In recent years, people are devoted to T suppression cell signal transduction pathway with development of new target spot antitumor drug.Signal transduction inhibitor lowers existence and the proliferation signal of tumour, promotes apoptosis, instead of by cytotoxicity, therefore selectivity is higher, toxic side effect is less.Existing tens kinds of signal transduction inhibitors are applied to clinical treatment tumour at present, be mainly tyrosine kinase inhibitor series antineoplastic medicament, the wherein comparative maturity of the compound exploitation of 4-(substituted anilinic) quinazoline structure type, as the micromolecular inhibitor Gefitinib (Iressa) of EGFR Tyrosylprotein kinase target spot, erlotinib (Tarceva) and lapatinibditosylate (Lapatinib) etc.
Gefitinib (Gefitinib), trade(brand)name Iressa (Iressa), the EGFR tyrosine kinase inhibitor of AstraZeneca exploitation, it is the epidermal growth factor recipient tyrosine kinase inhibitor entering clinical study the earliest, went on the market in 2002 in Japan, next year goes on the market in the U.S., is used for the treatment of the late period or Metastatic Nsclc (NSCLC) that previously receive chemotherapy.Erlotinib (Erlotinib), trade(brand)name Tarceva (Erlotinib), the EGFR tyrosine kinase inhibitor of OSI company exploitation, assigns in Genentech and Roche Holding Ag.Within 2004, in U.S.'s listing, be used for the treatment of NSCLC and carcinoma of the pancreas.Belong to the aniline quinazoline type small molecular inhibitor of first-generation treatment NSCLC, also be current uniquely confirmed EGFR tyrosine kinase inhibitor advanced Non-small cell lung to survival advantage, all effective to all kinds of Patients with Non-small-cell Lung, and better tolerance, without bone marrow depression and neurotoxicity, can significant prolongation lifetime, improve patients ' life quality.
Small molecule tyrosine kinase inhibitors is as new anti-tumor drugs targeting, and for the treatment of tumour and prevention open a fan new window, and its side effect is slight, has good tolerance.Although existing more than 10 small molecule tyrosine kinase inhibitors is that clinical cancer therapy has made very large contribution at present, but still needs to find that some have the other compound of the pharmacological characteristics of better activity in vivo and/or improvement than existing tyrosine kinase inhibitor.Therefore develop new improvement or more efficient tyrosine kinase inhibitor, more in depth understand relation between such medicine and known target protein and its mechanism playing antitumor action has great importance to clinical therapy of tumor.
The invention discloses the tyrosine kinase inhibitor of the novel Benzoquinazole of a class and ortho position fluorine replacement structure, these compounds can be used for the medicine preparing tumour.
