Embodiment 1

[0020] The activity and selectivity of the compounds of Example 1 inhibiting EGFR in vitro

[0021] Screening of EGFR kinase in vitro activity: The method used in the experiment is Caliper Mobility Shift Assay, which is a detection platform based on the mobility detection technology of microfluidic chip technology. Experimental steps: configure 1.25x kinase reaction buffer (62.5mmol / L HEPES, pH 7.5; 0.001875% Brij-35; 12.5mmol / LMgCl2; 2.5mM DTT) and kinase reaction termination solution (100mmol / L HEPES, pH 7.5; 0.015 %Brij-35; 0.2% Coating Reagent#3); Add 10 μl of 2.5x FGFR1 Kinase Solution (in 1.25x Kinase Reaction Buffer) Add kinase), incubate at room temperature for 10min, then add 10μl of 2.5x substrate peptide solution (add FAM-labeled peptide and ATP to 1.25x kinase reaction buffer), add 25μl kinase reaction stop solution after reacting at 28°C for a specific time . Test and collect data on Caliper, inhibition rate of kinase activity=(max-conversion) / (max-min)*100. "m...

Embodiment 2

[0024] Antitumor activity verification of compound on the cell level in Example 2

[0025] The anti-tumor activity of compound WZ00411 at the cell level by MTT method was selected to contain EGFR T790M Highly expressed human NSCLC cell line (H1975), EGFR WT Seven kinds of cells, including the highly expressed human large cell lung cancer cell line (A549) and the human lung cancer cell line with primary dislocation mutation of EGFR (HCC827), were tested for their proliferation inhibitory activity. During the determination, PBS was used as the blank control, EGF was used as the negative control, (EGF+WZ4002) was used as the positive control, (EGF+sample to be tested) was used as the experimental group, 6 concentration gradients were set for each sample, and the IC was calculated. 50 value.

[0026] The effect of active compounds on intracellular EGFR pro-proliferation signaling pathway: the compound WZ00411 was selected, and EGF combined with different concentrations of WZ0041...

Description

technical field [0001] The invention belongs to the field of medicinal chemistry, in particular, the invention relates to a pyrazol[5,6-d]pyrimidine compound with good antitumor activity. In addition, the present invention also relates to a pharmaceutical composition containing the compound and its use in the preparation of antitumor drugs and the like. Background technique [0002] Lung cancer is one of the malignant tumors with the highest morbidity and mortality. Worldwide, lung cancer causes more than 1 million deaths per year. In my country, the morbidity and mortality of lung cancer rank first among malignant tumors, among which non Small cell lung cancer (NSCLC) is the most common, accounting for more than 85% of the total number of cases. At present, classic surgical resection or radiotherapy and chemotherapy often have many defects such as high postoperative recurrence rate, high toxicity and side effects, metastasis and drug resistance. In view of the important ro...
