Description
Technical field
The present invention relates to a class 4-substituted benzene amino-3-nitroquinoline compounds, this compounds is inhibited to the cell growth of being rich in EGF-R ELISA (EGFR), can be used for preparing the medicine of the disease that the excessive or undesired hyperplasia of treatment causes, the invention still further relates to the preparation method of this compounds.
Background technology
Cancer is a big persistent ailment of serious harm human health.The annual cancered people in the whole world has 9,000,000, and the patient who dies from cancer is 6,000,000, and China's cancer year number of the infected is about 1,200,000, and the number of dying from cancer every year is up to more than 900,000, and patient to be treated surpasses 1,500,000.Capturing the cancer difficulty is medical worker's great task.
The medicine that people study and use for a long time all is with the effect target of cancer cells as medicine, thus cytotoxic drug be always the treatment cancer main medicine, but indeterminable all the time is the toxic side effect problem of this kind cancer therapy drug.Raising along with biotechnology, and subject development such as combinatorial chemistry, high flux screening, the searching of cancer therapy drug progresses into aims at the specific proteic stage, and wherein, the vital role of protein tyrosine kinase in cancer cell multiplication makes it become the cancer therapy target of very attractive.Protein tyrosine kinase (PTKs) plays crucial effect in the tumour generating process, having known has expression of proto-oncogenes over half to possess the active albumen of PTK.The effect of protein tyrosine kinase is that the phosphate of ATP is transferred on the specific tyrosine residues of functional protein, and the processes such as growth, propagation and differentiation of this tyrosine phosphorylation process energy regulating cell.
Research is EGF-R ELISA (EGFR) the most widely in the protein tyrosine kinase, EGFR is the transmembrane glycoprotein of a 170KDa, and its structure comprises the outer ligand binding domain of film, membrane-spanning domain, cell intracellular domain (possessing the PTK activity) and a C-terminal structural domain.Epidermal Growth Factor Receptor Family comprises four member: EGFR (ErbB-1), ErbB-2 (HER2), ErbB-3 (HER3), ErbB-4 (HER4).
The cancer clinical study shows that this receptor and its part all have important relation with a lot of tumours, the overexpression of EGFR occurs in 60% the cancer.This exception table has a variety of forms now, but every kind all can cause excessive tyrosine phosphorylation signal to import cell into unusually.In cell system, EGF or other ErbB family part often cause uncontrollable cell proliferation, thereby make cell be converted into typical abnormal morphology by normal morphology.Outer part of film and EGFR combination cause the EGFR acceptor to form dimer (homodimer or special-shaped dimerization), activate Tyrosylprotein kinase, import proliferation signal into cell.Utilize drug effect in EGFR, can end the proliferation signal that it mediates, thereby stop the excessive breeding of cancer cells.Have two class medicines can play such effect: a class is a monoclonal antibody, and another kind of is small-molecule drug.The mode of action of monoclonal antibody drug is the outer part of film that occupies EGFR, endogenous ligands such as EGF can't be combined with EGFR, thereby stop signal to import cell into.Small-molecule drug then by Tyrosylprotein kinase catalytic domain in the blocking-up EGFR born of the same parents, stops tyrosine phosphorylation, thereby has blocked the cell proliferation signal.
Small molecules EGFR inhibitor comprises natural product inhibitor and organic synthesis compound.The research of natural product inhibitor mainly be by the natural product structural modification is sought the EGFR inhibitor (Alexander J.Bridges, Chem.Rev.2001,101,2541-2571).The natural product inhibitor has better inhibited activity to EGFR, but because the reason of aspects such as cytotoxicity, enzyme selectivity (especially kinases selectivity) and the mechanism of action does not find the natural product parent nucleus with drug development future at present as yet.
The organic synthesis type small molecular inhibitor can be divided into reversible inhibitor and irreversible inhibitor according to the mode of action with EGFR, can be divided into 4-phenylamino (mixing) ring miazines and 4-phenylamino-3-cyano quinolines class according to the parent nucleus type.4-phenylamino (mixing) ring miazines is to study a class EGFR inhibitor the most widely, comprises 4-phenylamino quinazoline ditosylate salt, 4-phenylamino Pyridopyrimidine class and 4-phenylamino Pyrrolopyrimidine etc., and wherein 4-phenylamino quinazoline ditosylate salt is the most representative.
By the end of the year 2004, there has been the synthetic class inhibitor Iressa of a kind of EGFR to pass through FDA authentication listing as the active drug of treatment non-small cell carcinoma, also have tens kinds of medicines to be in senior clinical experimental stage in addition.
Still there are a lot of problems in the exploitation of EGFR inhibitor, as causes the unknown toxic problem of 4-phenylamino quinazoline compounds that people pay close attention to, the problem of enzyme selectivity etc.Address these problems, the EGFR inhibitor of development of new is the popular research topic of present world the world of medicine.
Kinds of tumors such as squamous cell carcinoma, neurospongioma and former generation the human breast carcinoma kind amplification of EGFR gene is all arranged, wherein, squamous cell carcinoma is A431 and MCF-7 MDA-MB-468, becomes focus (the Shimizu N et al that studies EGF effect and EGFR function now owing to the high-caliber EGFR of its abnormal expression and to the abnormal response of EGF; PNAS, 1983,801:1337).Unusual high-caliber EGFR in the A431 cell is relevant with No. 7 chromosomal transposition, and at No. 7 chromosomal p13, q22 contains in the zone c-erbB/EGFR gene.Also found the amplification of R gene in the MDA-MB-468 human breast cancer cell, and be positioned No. 7 chromosomal zone of unusual apparent generation (7pABR) go up (Filmus J et al.Somat Cell Mol Genet1984,10-45).Therefore, the EGFR inhibitor is that the cell proliferation of A431 and MCF-7 MDA-MB-468 also can play effect for the squamous cell carcinoma that suppresses to be rich in EGFR.
In sum, with EGFR as the cancer target, the EGFR inhibitor that designs and synthesizes, must be inhibited to the growth of cancer cells that is rich in EGF-R ELISA (EGFR), also can be used for preparing the medicine of the disease that the excessive or undesired hyperplasia of treatment causes, the exploitation of cancer therapy drug is had outstanding meaning.
