Abstract
The invention provides a group of 4-substituted phenylaminoquinoline compounds having antitumor activity, relates to the field of pharmaceutical chemistry and particularly relates to a group of tyrosine kinase inhibitors (4-substituted phenylaminoquinoline compounds) having antitumor activity. The compounds have a chemical structure shown in general formula (I). The compounds have an inhibiting effect on EGFR (epidermal growth factor receptor) high-expression tumors and an especially strong inhibiting effect on stomach cancer cells. In the general formula (I), R1 is F or H, R2 is H or OCH3, and R3 represents one or more of halogen, CH3, OCH3, CH(CH3)2, NO2, OH and CN.
Description
Technical field
The present invention relates to the pharmaceutical chemistry field, be specifically related to one group of 4-substituted benzene aminoquinoline compounds with anti-tumor activity.
Background technology
Tyrosylprotein kinase (PTKs) is the key protein matter of intracellular signal transduction pathway, is that a class can catalytic tyrosine residue phosphorylation, the kinases that has vital role in cell growth, propagation, differentiation.The unconventionality expression of Tyrosylprotein kinase will cause cell proliferation to be regulated getting muddled, and will be also closely related with the chemotherapy resistance of the invasion and attack of tumour and transfer, tumor neovasculature generation, tumour.
Research is EGF-R ELISA (EGFR) the most widely in the protein tyrosine kinase, over surplus in the of nearly ten year, people design and filter out and can attack with EGFR is the organic micromolecule compound of target spot, and wherein successfully listings such as Buddhist nun are replaced for Buddhist nun and Ka Nai in imatinib, Gefitinib, dust Lip river.In these organic micromolecule compounds, quinazoline compounds is one of the most successful antineoplastic chemotherapy medicine classification, and Gefitinib, dust Lip river all belong to the quinazoline ditosylate salt tyrosine kinase inhibitor for Buddhist nun and Ka Nai for Buddhist nun etc.Based on this, the Pharmaceutical Chemist pair quinoline compound close with the quinazoline chemical structure carried out extensive studies, as the exploitation HKI-272 of Wyeth, SKI-606 is a 3-cyano quinolines class tyrosine kinase inhibitor, CN100540551C, CN100540552C discloses the anti-tumor activity of 3-cyano quinoline compound, CN1830964A discloses the restraining effect of 4-substituted benzene amino-3-nitroquinoline compound to A-431 human skin squamous cell carcinoma and MDA-MB-468 human breast cancer cell, and CN101258129A discloses the anti-tumor activity of 8-methoxyl group-2-phenoxyquinolines compound.
Summary of the invention
The object of the present invention is to provide a kind of is raw material with 2-anisidine (or 3-fluoroaniline) with ethoxy methylene diethyl malonate (EMME), through getting 4-chloroquinoline compound through condensation, the cyclization of Gould-Jacobs high temperature, hydrolysis, decarboxylation, chlorination reaction, further prepare 4-substituted benzene aminoquinoline compounds again with substituted aniline generation nucleophilic substitution reaction, this compound is inhibited to the tumour of EGF-R ELISA (EGFR) high expression level, especially has stronger restraining effect for stomach cancer cell.
The objective of the invention is to be achieved through the following technical solutions:
Primary aspect of the present invention has provided formula
ICompound:
Wherein, R
1=F or H,
R
2=H or OCH
3,
The one or more halogens of R3=, CH3, OCH3, CH (CH3) 2, NO2, OH, CN
Preferred compound of the present invention is specifically represented with following formula:
Compound of the present invention is adopted in the following method and is made:
The present invention also provides the application of compound at the preparation antitumor drug.
Compound of the present invention is estimated with the pharmacology inspection procedure of standard, selecting tumour cell human cervical carcinoma Hela cell and people's cancer of the stomach BGC-823 cell of EGF-R ELISA (EGFR) high expression level is target cell, detect of the inhibition of this compounds with mtt assay, by power to the growth-inhibiting comparative compound antitumor action of tumour cell to growth of tumour cell.
Below be the pharmacological experiment and the data of The compounds of this invention:
The human cervical carcinoma Hela cell who takes the logarithm vegetative period and people's cancer of the stomach BGC-823 cell cultures are in 96 well culture plates, and every hole 100 μ L(approximately contain 4000 cells), put 37 ℃, cultivate in the 5% CO2 incubator.The administration group adds the tester that contains different concns after cultivating 24h, and each concentration is established three parallel holes at least.Negative control group adds and the isopyknic solvent of administration group, and establishes the blank group that only adds substratum, puts 37 ℃, cultivates in the 5% CO2 incubator.Abandon nutrient solution after 48 hours, every hole adds 50 μ L 1mg/mL MTT solution (PBS preparation).Hatched 4 hours for 37 ℃, abandon supernatant, every hole adds DMSO 150 μ L Rong Xie Jia Za particles, the gentle agitation dissolving.Under microplate reader wavelength 490nm condition, measure optical density value (OD), calculate the inhibiting rate of medicine pair cell with following formula:
Inhibiting rate=(negative control group OD value-dosing group OD value)/(negative control group OD value-blank group OD value) * 100%.
The pharmacological results sees Table 1 and table 2
Table 1 compound of the present invention is to the inhibiting rate (%) of cervical cancer HeLa cell growth
Table 2 compound of the present invention is to the inhibiting rate (%) of cancer of the stomach BGC-823 cell growth
Gefitinib is the 4-anilinoquinazoline class EGFR tyrosine kinase inhibitor of AstraZeneca (AstraZeneca) company development, obtains the FDA approval in U.S.'s listing in 2003, is the active good antitumor medicine of open report, with it as positive control drug.Have certain anti-tumor activity by table 1 and the visible compound of the present invention of table 2, part of compounds is better than the positive control drug Gefitinib to HeLa Cells and people's cancer of the stomach BGC-823 cytoactive.
Advantage of the present invention and effect are:
The The compounds of this invention structure is simple relatively, is easy to preparation.Anti tumor activity in vitro studies show that this compound is inhibited to the tumour of EGF-R ELISA (EGFR) high expression level, especially has stronger restraining effect for stomach cancer cell.
