Description

  The present invention relates to a novel ROS tyrosine kinase inhibitor containing an aminopyrazine derivative as an active ingredient.

ROS tyrosine kinase is a receptor-type protein tyrosine kinase similar to the EGF receptor, and is considered to be involved in signal transduction related to cell proliferation and differentiation (see, for example, Non-Patent Document 1).
To date, changes in the gene level of ROS tyrosine kinase have been reported in several malignant tumors. For example, overexpression of ROS tyrosine kinase is reported in glioma, meningioma, etc. (see, for example, Non-Patent Documents 2 and 3), and patient cells of chronic myelomonocytic leukemia (for example, see Non-Patent Document 4). Has been. Furthermore, a FIG-ROS fusion gene in a glioblastoma cell line (see, for example, Non-Patent Document 5), an SLC34A2-ROS fusion gene in a non-small cell lung cancer cell line (see, for example, Non-Patent Document 6), and a non-small cell lung cancer. A CD74-ROS fusion gene has been found in clinical specimens (see, for example, Non-Patent Document 6).
In addition, it has been reported that the FIG-ROS fusion gene has properties as an oncogene (see, for example, Non-Patent Document 7). Furthermore, ROS tyrosine kinase is a homolog of the oncogene v-ROS of a virus that infects birds (see, for example, Non-Patent Document 8), and activation of ROS tyrosine kinase is thought to lead to canceration.
More recently, a FIG-ROS fusion gene has been found in cholangiocarcinoma (see, for example, Non-Patent Document 9), suggesting the possibility of abnormal ROS in liver cancer, kidney cancer, pancreatic cancer, and testicular cancer. (For example, refer to Patent Document 1).
From the above, it is considered that the ROS tyrosine kinase inhibitor is effective as a therapeutic agent for the diseases described above.

Test Example 1 ROS tyrosine kinase inhibitory activity test

1. Preparation of test substance The test substance was dissolved in dimethyl sulfoxide (DMSO) at 10 mM, and further diluted with DMSO to a concentration 100 times the measured concentration (10, 1 μM). Further, the test substance solution was diluted 25 times with assay buffer. As a negative control, a solution obtained by diluting DMSO 25 times with assay buffer was used. (20 mM HEPES (pH 7.5), 0.01 (v / v)% Triton X-100, 2 mM dithiothreitol) was used as the assay buffer.
2. Measurement of ROS tyrosine kinase activity

For the measurement of the activity, an off-chip mobility shift assay (MSA) method was used. 5 μL of a test substance solution having a concentration 4 times the final concentration prepared in the assay buffer, 5 μL of a substrate / ATP / metal solution (200 μM ATP 20 mM MgCl ₂ 4000 nM peptide substrate) having a concentration 4 times the final concentration dissolved in the assay buffer, and the assay buffer 10 μL of the ROS tyrosine kinase solution having a concentration twice the final concentration dissolved in the solution was mixed in the well of a polypropylene 384-well plate and reacted at room temperature for 1 hour (n = 2). Wells without kinase were used as background wells. After completion of the reaction, 60 μL of Termination Buffer (Quick Scout Screening Assist MSA; Carna Biosciences) was added to stop the reaction. The substrate peptide and phosphorylated peptide in the reaction solution were separated and quantified by LabChip 3000 system (Caliper Life Science).

3. Analysis of Measurement Results The fluorescence intensity of the substrate peptide and phosphopeptide quantified by the above system is expressed as the peak height of the waveform data. The inhibition rate (%) of the kinase was determined by using the height of the substrate peptide peak (S) and the height of the phosphorylated peptide peak (P), [(1 − {[P / (P + S)] Mean value—mean value of [P / (P + S)] of background well}} / {mean value of [P / (P + S)] of well with 0 drug concentration—of [P / (P + S)] of background well Average value}] × 100.
