Description

TECHNICAL FIELD

The present invention belongs to the field of medicine, and in particular relates to a pyrimidine heterocyclic compound, and a preparation method and medical use thereof.

BACKGROUND OF THE INVENTION

Cyclin dependent kinase (CDK)/cyclin complex is identified as a conservative component of an RNA polymerase II transcription mechanism. At present, there are 20 mammalian CDKs. In mammalian CDKs, the CDK7 has solid kinase activity, and only the CDK7 has dual-functions of regulation of cell cycle progression and transcription. In the cytosol, the CDK7, as a heterotrimer complex, is considered to play a role of the CDK1/2/4/6 activating kinase (CAK), and therefore, the phosphorylation of the CDK7 to the conserved residues in the CDK1/2/4/6 is necessary for fully catalytic CDK activity and cell cycle progression. In the cell nucleus, the CDK7 forms a kinase core of an RNA polymerase II transcription factor complex and is responsible for phosphorylating the C-terminal domain (CTD) of the RNA polymerase II, which is a necessary step for gene transcription initiation. Two functions (namely CAK and CTD phosphorylation) of the CDK7 support the key aspects of cell proliferation, cell cycle and transcription together.

As an general regulatory factor of transcription, the CDK7 can be used as a therapeutic target for treating many diseases and syndromes. The CDK7 can interact with multiple transcription factors, cofactors, chromatin regulatory factors and mutants in non-coding RNA in a transcriptional regulatory region to regulate transcription. These transcription factors, cofactors, chromatin regulatory factors or mutants in non-coding RNA can cause cancers, autoimmune diseases, nervous system disorders, developmental syndromes, diabetes, cardiovascular diseases, obesity, etc. Some of these transcription factors can control RNA polymerase II mediated transcription initiation and elongation, and when their expressions or functions change, produce invasive tumor cells (such as those caused by c-Myc) or some forms of autoimmunity (such as those caused by AIRE) may occur. Therefore, the CDK7 kinase can promote the abnormal expression of some tumor-related transcription factors by regulating the overall transcription process, and promote tumor development by regulating the phosphorylation of key kinases in the cell cycle. More importantly, the CDK7 regulates the expression of oncogenic transcription factors more significantly than other housekeeping genes in cancer cells. The inhibition of the CDK7 can differentially affect the transcription of some oncogenes and housekeeping genes, thus ensuring the therapeutic window. Transcription regulation and cell cycle regulation by regulating CDK7 mediated phosphorylation may treat diseases with abnormal proliferation, including cancers. As an general regulatory factor of transcription, the CDK7 can also be used as a therapeutic target for treating diseases such as inflammations, viral replication such as HIV and EBV, cancers and cardiac hypertrophy.

The high sequence and structure similarity of kinase domains of CDK family member hinder the discovery of CDK7 selective inhibitors. Therefore, the development of selective CDK7 inhibitors is of great value for clinical applications.

This experiment was used for determining the inhibition of the activities of CDK2, CDK7, CDK9 and CDK12 kinases by the compound. The kinase reaction carried out by the present invention was measured in a 384-well plate, the final measured volume was 16 μl, and the reaction temperature was 27° C. The concentrations of the kinases were determined by optimization experiment. The specific experimental process was as follows:

• • 1) preparation of kinase solutions:
  • kinase solution (CDK2/Cyclin E1): the kinase was diluted in a assay buffer solution ((20 mM MES pH 6.75, 0.01% Tween 20, 0.05 mg/mL BSA, 2 mM MgCl₂) to obtain an enzyme solution with the corresponding 2.4× concentration;
  • kinase solution (CDK7/Cyclin H/MAT1): the kinase was diluted in the assay buffer solution (20 mM MES pH 6.75, 0.01% Tween 20, 0.05 mg/mL BSA, 6 mM MgCl₂) to obtain an enzyme solution with the corresponding 2.4× concentration;
  • kinase solution (CDK9/Cyclin T1): the kinase was diluted in the assay buffer solution (20 mM MES pH 6.75, 0.01% Tween 20, 0.05 mg/mL BSA, 10 mM MgCl₂) to obtain an enzyme solution with the corresponding 2.4× concentration; and
  • kinase solution (CDK12/Cyclin K): the kinase was diluted in a assay buffer solution (80 mM MES pH 6.5, 0.01% Tween 20, 0.05 mg/mL BSA, 10 mM MgCl₂) to obtain an enzyme solution with the corresponding 2.4× concentration.
  • 2) Preparation of compound solutions: the compound was dissolved in dimethyl sulfoxide (DMSO) at a concentration of 10 mM, the compound was diluted to 10 concentration gradients of 25 nM to 500 μM with DMSO during use, diluted in ultrapure water by 8.3 times respectively to obtain compound solutions with 6× concentration.
  • 3) Preparation of a polypeptide substrate and ATP solution: the polypeptide substrate and ATP were diluted in the assay buffer solution to obtain a polypeptide substrate and ATP mixed solution with 2.4× concentration.
  • 4) Kinase reaction process:
  • 2 ul of the test compound solution, 5 ul of the polypeptide substrate and ATP mixed solution and 5 ul of an enzyme solution were mixed and incubated at 27° C. (CDK2 was incubated for 60 min, CDK7 was incubated for 70 min, CDK9 was incubated for 70 min, and CDK12 was incubated for 280 min), and then 4 ul of EDTA with a concentration of 150 mM was added into each sample to terminate the reaction. The assay buffer solution containing 20 μM of staurosporine was used for replacing the compound solution as 100% inhibition, and DMSO was used for replacing the compound solution as 0% inhibition. Each test had at least two parallel controls. Final concentration of a reagent in CDK2 assay: ATP was 100 μM, the polypeptide substrate (5-FAM-YSPTSPSYSPTSPSYSPT SPSKKKK) was 2 μM, and CDK2/Cyclin E1 was 0.5 nM; final concentration of a reagent in CDK7 assay: ATP was 50 μM, the polypeptide substrate (5-FAM-YSPTSPSYSPTSPSYSPT SPSKKKK) was 2 μM, and CDK7/Cyclin H/MAT1 was 3 nM; final concentration of a reagent in CDK9 assay: ATP was 50 μM, the polypeptide substrate (FITC-Ahx-GSRTPMY-NH2) was 2 μM, and CDK9/Cyclin T1 was 8 nM; and final concentration of a reagent in CDK12 assay: ATP was 30 μM, the polypeptide substrate (FITC-Ahx-GSRTPMY-NH2) was 2 μM, and CDK12/Cyclin K was 50 nM.
  • 5) Data calculation and analysis: electrophoretic separation was carried out on a fluorescent substrate and a phosphorylated product on a Caliper EZ Reader II to analyze a reaction mixture. The data was calculated with GraphPad Prism version 9.0, and an IC₅₀ value was obtained by adjusting a nonlinear regression model using a dose reaction curve. The calculation formula was Y=Bottom+(Top-Bottom)/(1+10{circumflex over ( )}((LogIC50−X)*HillSlope)). X represents a log value (log of dose or concentration); Y represents an inhibition rate (% inhibition, increasing as x increases) which was increased along with the increase of X; Top represents maximum response; Bottom represents baseline response; and HillSlope represents a curve slope. Due to the limitation of the detection lower limit of a CDK7/Cyclin H/MAT1 kinase activity experiment, the inhibition of the compound in the present invention on the CDK7 kinase activity reached the experiment detection lower limit, IC₅₀ could not accurately reflect the kinase activity inhibition capability of the compound, and the binding affinity K_D of the compound was detected by adopting a surface plasmon resonance (SPR) method. The compound had an inhibition effect on the activity of CDK2, CDK9 and CDK12 kinases, and IC₅₀ obtained by detection fitting under a Km ATP condition was used for calculating Ki (Cheng and Prusoff, Biochem. Pharmacol., 22(23)3099-3108, 1973), and the conversion formula was as follows: IC₅₀=K_i(1+[substrate/K_m])+[enzyme/2]. The results of the compounds are shown in Table 1.

The experiment adopted a Biacare S200 surface plasmon resonance device (GE Healthcare) to test the dynamics and affinity parameters of a CDK7/Cyclin H dimer and the compounds. Under a condition of 10 mM MES buffer solution with pH of 6.5, CDK7/Cyclin H dimer with concentration of 50 μg/mL was coupled to a CM5 sensing chip by amino group at flow rate of 5 μL/min. Target protein was fixed on a chip channel within 600 seconds, and 7,000-10,000 response value was achieved in general. The compound underwent 2 times of gradient dilution for 5 steps in 10 mM HEPES buffer solution with pH of 7.4 and comprising 150 mM NaCl, 0.05% of surfactant P20 and 2% of DMSO to reach a concentration range of 0.6-10 nM. Each concentration cycle of the compound was operated at 100 μL/min, 180 seconds of contact time and 1800 seconds of dissociation time. For each compound, the combination of a 0 nM compound control and a reference channel was deducted to remove background signals and normalization data. Biaccore S200 evaluation software and a kinetic model were used for carrying out titration overall fitting on the compound. Fitting data was optimized, the combination rate and the dissociation rate parameter of CDK7/Cyclin H were determined, and the affinity parameter K_D of the compound was calculated by the following equation. K_D (M)=k_off (s⁻¹)/K_on (M⁻¹s⁻¹), wherein K_on (ka) represents the combination rate, K_off (kd) represents the dissociation rate, and s⁻¹ (per second) and M⁻¹s⁻¹ (per mole per second) were the units of k_off and k_on. Based on the ratio of the K_i value of off-target CDK to the direct compound combination K_D of CDK7 (measured by SPR), the selectivity of CDK7 to the compound of CDK2, CDK9 or CDK12 was determined according to the following equation. Selectivity=K_{i, off-target}/K_{D, CDK7}. The result showed that the compound had excellent selectivity to CDK7 relative to CDK2/CDK9/CDK12, and the specificity of the compound to CDK7 was at least 100 times or 300 times and even more than 500 times to other CDK7.
