Description

Technical Field

[0001] Cross - Reference to Related Applications

[0002] This application claims the priority and benefit of Korean Patent Application No. 10 - 2022 - 0182613, filed on December 23, 2022, the disclosure of which is incorporated herein by reference in its entirety.

[0003] The present invention relates to a novel compound as a protein kinase inhibitor. Specifically, the present invention relates to a novel compound as a RON inhibitor. Background Art

[0004] There are known to be at least 400 protein kinases that catalyze the transfer of a phosphate group from adenosine triphosphate (ATP) to a protein substrate. Since the specific amino acid to which the phosphate group is transferred in the target protein is tyrosine, serine, or threonine, protein kinases are generally referred to as protein tyrosine kinases (PTKs) or serine / threonine kinases (STKs).

[0005] Protein kinases include a large class of structurally related proteins that are essential for regulating various signal transduction pathways within cells. The signal transduction pathways include many different signal transduction pathways by transferring a phosphate group to a target protein. These phosphorylation processes act as molecular on / off switches that can regulate the biological functions of target proteins or protein complexes. The proper function of protein kinases in signal transduction pathways is to activate or inactivate metabolic enzymes, regulatory proteins, receptors, cytoskeletal proteins, ion channels and pumps, transcription factors, etc. Improper regulation of signal transduction caused by defects in protein phosphorylation regulation is associated with many diseases, including inflammation, cancer, allergies / asthma, immune system diseases, central nervous system diseases, and angiogenesis.

[0006] Most kinases include a similar catalytic site consisting of 250 to 300 amino acids. Kinases can be classified according to the substrates they phosphorylate, and sequence motifs corresponding broadly to each of these kinase families have been identified.

[0007] Meanwhile, the receptor d'origine Nantais (RON) is one of the tyrosine - protein kinase receptors, also known as macrophage - stimulating 1 receptor (MST1R), which is reported to promote the invasion and metastasis of cancer cells. Overexpression of RON has also been reported in various tumor types.

[0008] Activation of tyrosine protein kinases, such as RON mentioned above, in tumor cells enhances the proliferation, invasion and metastasis of tumor cells, and also increases the resistance of tumor cells to apoptosis and cytotoxic therapies. Therefore, it is expected that selective small molecule kinase regulators targeting tyrosine protein kinases such as RON have therapeutic potential for treating cancers in which the activation of RON receptor or other receptors plays an important role in the occurrence and progression of primary tumors and secondary metastases. Therefore, continuous research is being conducted on various inhibitors to selectively inhibit the activity of RON, one of the tyrosine protein kinases. Summary of the Invention

[0508] The cMET protein was diluted to a concentration of 263 nM in cMET storage buffer (50 mM Tris-HCl (pH 7.5), 150 mM NaCl, 0.05% Brij35, 1 mM DTT, 10% glycerol) and then further diluted to 2 nM with 1x kinase reaction buffer. As a substrate mixture, a MET-specific substrate mixture (5 μM TK peptide, 10 mM ATP) was prepared at a concentration twice the final reaction concentration.

[0509] Subsequently, a 384-well plate was prepared. 2.5 μl of the diluted example compounds were added to each experimental group well, and 2.5 μl of a 4% DMSO solution was dispensed into the high control well and the low control well.

[0510] Subsequently, 2.5 μl of 2 nM cMET was dispensed into the high control well and the experimental group wells, and 2.5 μl of 1x kinase reaction buffer was added to the low control well. After centrifuging the mixture at 1000 RPM for 40 seconds at room temperature, the mixture was incubated at room temperature for 20 to 30 minutes. Then, 5 μl of the substrate mixture (2x) was dispensed into all wells. After centrifuging the mixture at 1000 RPM for 40 seconds at room temperature, the mixture was incubated at room temperature for 60 minutes. Then, 5 μl of 90 mM EDTA was added to all wells to terminate the reaction, and the mixture was incubated at room temperature for another 5 minutes. Thereafter, 5 μl of a 4x phosphotyrosine antibody containing europium (PerkinElmer) was added to all wells and incubated at room temperature for 60 minutes. After incubation, the 384-well plate was read using a Vison plate reader. At this time, the excitation wavelength was 340 nm, and the emission wavelengths were 620 nm and 665 nm. The IC 50 value of each example compound was obtained using the GraphPd Prism7 program.
