Embodiment 1

[0101] The concrete synthetic method of above-mentioned steps a-f is as follows:

[0102] Synthesis of tert-butyl (4-(2-chloro-5-nitropyrimidine-4-amino)phenyl)carbamate (step a)

[0103]

[0104] Weigh 2,4-chloro-5-nitropyrimidine (95mg, 0.49mmol) into a 10mL round bottom flask, add 3mL 1,4-dioxane, stir at room temperature, and take another (4-aminophenyl ) tert-butyl carbamate (100mg, 0.48mmol), N,N-isopropylethylamine (69mg, 0.53mmol) were dissolved in 2mL 1,4-dioxane, and added dropwise to the above reaction solution, dropwise After the addition was complete, the mixture was stirred at room temperature for 0.5 hour, followed by TLC until the starting material was completely converted. The solvent was removed by rotary evaporation, and the crude product was separated by silica gel column chromatography (petroleum ether / ethyl acetate=10:1, v / v) to obtain (4-(2-chloro-5-nitropyrimidine-4-amino)phenyl ) tert-butyl carbamate orange solid 144mg, yield 82%. 1 H NMR (400MHz, ...

Embodiment 2

[0212] Biological Activity Test Section

[0213] The experiment of the in vitro inhibitory effect of the compounds provided by the invention on the kinase activity of BLK and FLT3 was carried out as follows, wherein BLK and FLT3 were purchased from BPS, and staurosporine was used as a control compound.

[0214] Prepare 1x Kinase Substrate Buffer and Stop Buffer. 1x Kinase Substrate Buffer: 50mM HEPES, pH 7.5, 0.0015% Brij-35, 10mM Magnesium Chloride, 2mM DTT; Stop Buffer: 100mM HEPES, pH 7.5, 0.0015% Brij-35, 0.2% Coating Reagent#3, 50mM EDTA. Prepare compound solutions. Dissolve the compound in 100% DMSO, prepare a solution of 50 times the final maximum inhibitory concentration, and transfer 100 μL of the above solution to a 96-well plate; dilute the above compound solution to the final required concentration in sequence; two in the same 96-well plate Add 100 μL of 100% DMSO to the blank well as the no-compound and no-kinase control, this well plate is used as the original ...

Description

technical field [0001] The present invention relates to the synthesis of pteridinone compounds and their applications in the fields of medicinal chemistry and pharmacotherapeutics, specifically, the application of pteridinone compounds with different substituents in the preparation of drugs for tumors and immune diseases. application. Background technique [0002] Protein tyrosine kinase (protein tyrosine kinase) is a class of proteins that catalyze the transfer of γ-phosphate on ATP to specific amino acid residues in proteins. It plays a very important role in intracellular signal transduction pathways and regulates cell growth, A series of physiological processes such as differentiation and death. It has been shown that more than 50% of proto-oncogenes and their products have protein tyrosine kinase activity, and their abnormal expression will lead to the disorder of cell life cycle, and then lead to the occurrence of tumors. In addition, abnormal expression of tyrosine ...
