Quinoline that cyano group replaces and its production and use

Technical field

The present invention relates to some novel quinoline or its pharmacy acceptable salt, the methods of treatment that it has anti-tumor activity and therefore is applicable to human or animal body.The invention still further relates to the preparation method of described quinoline, the pharmaceutical composition that comprises them and their application in methods of treatment, for example be used for preventing or treating the application of the medicine of solid tumor disease in warm-blooded animal such as the human body in preparation.

Background technology

The disease that present many treatments are caused unusually by cell proliferation regulation and control such as the scheme of psoriasis and cancer have been utilized the compound that suppresses the synthetic and cell proliferation of DNA.So far, the compound that is used for this treatment has cytotoxicity usually, pretends usefulness but they have for quick noble cells such as cancer cells, and this effect is favourable.Developed at present the method for replaceable these cell toxicant antitumour drugs, for example the selective depressant of cell signal approach.The inhibitor of these types can show and strengthen selectively acting in the potentiality of antitumor cell, and therefore can reduce the probability of the adverse side effect that treatment has.

Eukaryotic cell makes like this and can carry out communication between the biological intravital cell constantly to many different extracellular signal reactions.The intracellular many physical responses of these Signal Regulation comprise propagation, differentiation, apoptosis and motion.The extracellular signal shows as various water-soluble factor form, comprises somatomedin and paracrine and endocrine factor.By the binding specificity transmembrane receptor, these parts to the intracellular signal transduction approach, therefore, pass signal transduction the extracellular signal combination plasma membrane and allow cell individual that its extracellular signal is replied.Many signal transduction processes are utilized the reverse process of protein phosphorylation effect, and described albumen participates in promoting above various cell responses.The phosphorylation state of target protein is regulated by specificity kinases and phosphoesterase, and these enzymes proteic about 1/3 are regulated all of mammalian genes group coding.Because phosphorylation is the very important regulation mechanism in the signal transduction process, therefore be understood that the not normal cell that will cause of approach is grown and prosoplasia in these cells, and (summary is referring to Cohen et al. therefore to promote transformation, Curr OpinChem Biol, 1999,3,459-465).

Well-known many Tyrosylprotein kinases sport the constitutive activity form and/or cause various human cells to transform after by overexpression.Kinase whose these sudden changes or overexpression form in accounting for the human tumor of significant proportion, all exist (summary referring to Kolibaba et al., Biochimica et BiophysicaActa, 1997,133, F217-F248).Because the vital role that Tyrosylprotein kinase has in the propagation of various tissues and differentiation has the research of a lot of development of new anti-cancer therapies all to concentrate on these enzymes.This family's enzyme is divided into two groups: receptor tyrosine kinase and nonreceptor tyrosine kinase, be respectively for example EGF acceptor and SRC family. from the big quantity research result of (comprising the Human Genome Project), about 90 kinds of Tyrosylprotein kinases in human genome, have been identified, wherein 58 kinds is receptor type, and 32 kinds for non-receptor type. they can be divided into 20 kinds of receptor tyrosine kinases and 10 kinds of nonreceptor tyrosine kinase subfamily (Robinson et al., Oncogene, 2000,19,5548-5557).

Receptor tyrosine kinase is to causing the mitogenesis signal transduction particularly important of cellular replication.These big glycoprotein of crossing over cytoplasmic membrane have the integrated structure city, extracellular at its ligands specific (for example Urogastron of EGF acceptor (EGF)).Binding partner causes the kinase whose enzymic activity of activated receptor, and kinase activity is by the intracellular portion coding of acceptor.Crux tyrosine amino acid in this active phosphorus acidifying target protein makes the proliferation signal transduction pass cytoplasmic membrane.

The erbB family of known receptor Tyrosylprotein kinase (comprises EGFR, erbB2, erbB3 and erbB4) usually participate in promoting the propagation of tumour cell and survival (to summarize referring to Olayioye et al, EMBO J., 2000,19,3159). a kind of mechanism that can finish this effect is the overexpression receptor protein, overexpression is the result of gene amplification normally. and this observes in a lot of common human cancers, and (summary is referring to Mapper et al., Adv.Cancer Res., 2000,77,25), mammary cancer (Sainsbury et al., Brit.J.Cancer, 1988 for example, 58,458; Guerin et al., OncogeneRes., 1988,3,21; Slamon et al., Science, 1989,244,707; Kliin et al., BreastCancer Res..Treat., 1994,29,73; Summary is referring to Salomon et al., Crit.Rev.Oncol.Hemato., 1995,19,183); Nonsmall-cell lung cancer (NSCLC) comprises gland cancer Cernyet al., Brit.J.Cancer, 1986,54,265; Reubi et al., Int.J.Cancer, 1990,45,269; Rusch et al., Cancer Research, 1993,53,2379; Brabender et al., Clin.Cancer Res., 2001,7,1850) and other lung cancer (Hendler et al., Cancer Cells, 1989,7,347; Ohsaki et al., Oncol, Rep., 2000,7,603), bladder cancer (Neal et al., Lancet, 1985,366; Chow et al., Clin.Cancer Res., 2001,7,1957, Zhau etal., Mol Carcinog., 3,254), esophagus cancer (Mukaida et al., Cancer, 1991,68,142), gastrointestinal cancer colorectal carcinoma, the rectum cancer or cancer of the stomach (Bolen et al., Oncogene Res. for example, 1987,1,149; Kapitanovic et al., Gastroenterology.2000,112,1103; Ross et al., Cancer Invest., 2001,19,554), prostate cancer (Visakorpi et al., Histochem.J., 1992,24,481; Kumar et al., 2000,32,73; Scher et al., J.Natl.Cancer Inst., 2000,92,1866), leukemia (Konaka et al., Cell, 1984,37,1035, Martin-Suberoet al., Cancer Genet Cytoggenet., 2001,127,174), ovarian cancer (Hellstrom et al., Cancer Res., 2001,61,2420), head and neck cancer (Shiga et al., Head Neck, 2000,22,599) or carcinoma of the pancreas (Ovotny et al., Neoplasm, 2001,48,188).Along with the expression of more mankind tumor tissue being tested the erbB family of its receptor tyrosine kinase, expection future their ubiquity and importance will further strengthen.
