7- azaindoles and its application containing dihydrogen dazin structure
Technical field
The present invention relates to new Benzazole compounds, in particular to a kind of 7- Azaindoles containing dihydrogen dazin structure
Compound and its application.
Background technique
Malignant tumour is a kind of disease for seriously endangering human health and life.The death rate caused by human malignancies is only
Inferior to angiocarpy, it is arranged in second.The whole world is about diagnosed to be 10,000,000 tumor patients every year at present, and 7,000,000 people die of by swelling
Related disease caused by tumor, there are about 1,800,000 people to die of cancer, Zhan Quanqiu 1/4 every year for China.
C-Met kinases is hepatocyte growth factor receptor, is one of tyrosine kinase receptor family member, the c-Met of people
Gene is located at No. 7 chromosome long arm (7q31), and about 110kb contains 21 exons.Mature c-Met is by 5.0 × 104α it is sub-
Base and 1.4 × 105β subunit form heterodimer, extracellular region be α chain, intracellular region be β chain, two chains by disulfide bond be connected.
The phosphorylation of the Tyr1234 and Tyr1235 of region of activation can activate c-Met kinases.
C-Met kinases is widely present in epithelial tissue, is played an important role in embryonic development and wound healing.
Recent research indicate that c-Met kinases lung cancer, colon cancer, liver cancer, the carcinoma of the rectum, gastric cancer, kidney, oophoroma, glioma,
Abnormal high expression, mutation or activity change are presented in the tumor tissues such as melanoma, breast cancer, prostate cancer.C-Met kinases
The proliferation that can promote tumour cell adjusts the migration of tumour cell, enhances the invasive ability of tumour cell and induced tumor is new
The generation of angiogenic.
Currently, c-Met kinases has become an important target spot of anti-tumor drug research.Discovery oforally

The pharmacological research of product of the present invention
Extracorporeal anti-tumor cell activity
External suppression has been carried out to the 7- azaindoles containing dihydrogen dazin structure of general formula I according to the invention
Lung carcinoma cell H460, colon cancer cell HT-29, gastric carcinoma cells MKN-45, human umbilical vein endothelial cell and bladder cancer cell U- processed
87MG screening active ingredients.
(1) after 2~3 stabilizations of cell recovery and passage, make it from culture bottle bottom with trypsin solution (0.25%)
Digestion is got off.After cell dissociation buffer is poured into centrifuge tube, culture solution is added later to terminate digestion.By centrifuge tube in 800r/
It is centrifuged 10min under min, 5mL culture solution is added after discarding supernatant liquid, piping and druming mixes cell, draws 10 μ L cell suspensions and is added
It is counted in cell counting board, adjustment cell concentration is 104A/hole.Except the hole A1 is that blank well is not added extracellularly in 96 orifice plates, remaining
100 μ L cell suspensions are all added.96 orifice plates are put into incubator and are cultivated for 24 hours.
(2) with 50 μ L dmso solution given the test agent, appropriate culture solution is then added, sample is made to be dissolved into 2mg/mL
Then sample is diluted to 20,4,0.8,0.16,0.032 μ g/mL in 24 orifice plates by medical fluid.
3 holes are added in each concentration, wherein surrounding two rows, two column cell growing way is affected by environment larger, it only and is blanc cell
Hole uses.96 orifice plates are put into incubator and cultivate 72h.
(3) band medicine culture solution in 96 orifice plates is discarded, is rinsed cell twice with phosphate buffer solution (PBS), in every hole
Middle 100 μ L of addition MTT (tetrazole) (0.5mg/mL) is put into incubator after 4h, discards MTT solution, and dimethyl sulfoxide is added
100μL.Oscillation dissolves survivaling cell sufficiently with MTT reaction product formazan on magnetic force oscillator, is put into microplate reader and measures
As a result.Drug IC can be found out by Bliss method50Value.
Inhibition lung carcinoma cell H460, colon cancer cell HT-29, the gastric carcinoma cells MKN-45, lung adenocarcinoma cell of compound
A549 and bladder cancer cell U-87MG Activity Results are as shown in table 2.
The test of c-Met enzymatic activity
Test for measuring c-Met kinase activity is based on enzyme-linked immunosorbent assay (ELISA).Concrete operations are:
At room temperature, on the coated plate of 0.25mg/mL PGT, by embodiment compound, 50pM c-Met, (His- is marked
Recombined human Met (end amino acid 974-), by baculovirus expression and 5 μM of ATP in test buffer (25mM MOPS,
pH 7.4,5mM MgCl2,0.5raM MnCl2, 100 μM of sodium orthovanadates, 0.01%TritonX-100,1mM DTT, last DMSO
Concentration 1% (v/v)) it incubates 20 minutes.By rinsing removing reaction mixture and horseradish peroxidase being conjugated with 0.2 μ g/mL
(HRP) phosphotyrosine monoclonal antibody specific (PY20) detects phosphorylated polymer substrate.It is aobvious that the termination of 1M phosphoric acid is added
After color, pass through the color of the substrate (TMB) of spectrophotometry quantitative chromogenic at 450nm.Embodiment compound is to c-Met kinases
Inhibition data it is as shown in table 2.
Table 2:
From above-mentioned test result it can be clearly seen that the compound of the claimed general formula I of the present invention, has good
Anti tumor activity in vitro, quite or better than the anti-tumor drug cis-platinum listed.
The compound of formula of I of the present invention can be administered alone, but usually give with pharmaceutical carrier mixture, described medicinal
The selection of carrier will be according to required route of administration and standard pharmaceutical practice, separately below with the various drug agent of such compound
Type, such as the preparation method of tablet, capsule, injection, aerosol, suppository, film, pill, externally-applied liniment and ointment,
Illustrate its new opplication in pharmaceutical field.
