HETEROARYL DERIVATIVE COMPOUND AND USE THEREOF

TECHNICAL FIELD

The present disclosure relates to a heteroaryl derivative compound and medicinal uses thereof. Specifically, the present disclosure relates to a heteroaryl derivative compound having HER2 and/or EGFR inhibitory activity.

BACKGROUND ART

Protein kinases act as molecular switches to participate in signal transduction pathways, and the transition between active and inactive states of target proteins by kinases in cells should be smoothly controlled. If the transition between the active and inactive states is abnormally controlled, intracellular signal transduction is excessively activated or deactivated to induce uncontrollable cell division and proliferation. In particular, abnormal activation by mutation, amplification and/or overexpression of protein kinase genes causes the development and progression of various tumors or plays a crucial role in the development of various diseases such as inflammatory diseases, degenerative brain diseases, and autoimmune diseases.

In particular, HER2 (ErbB2), which is a receptor tyrosine kinase of the ErbB family, forms homodimers or heterodimers with other EGFR receptors such as HER1 (EGFR, ErbB1), HER3 (ErbB3), or HER4 (ErbB4) and is activated by autophosphorylation at intracellular tyrosine residues to play an important role in cell proliferation, differentiation and survival in normal cells and cancer cells (Di Fore P P, et al., Science. 1987; 237: 178-182). HER2 is known to be overexpressed in various carcinomas such as breast cancer, gastric cancer and ovarian cancer (Hardwick R, et al., Eur. J Surg Oncol. 1997 (23): 30-35; Korkaya H, et al., Oncogene. 2008; 27 (47): 6120-6130;).

In addition, it is known that epidermal growth factor receptor (EGFR), which is another ErbB family, is abnormally active in many epithelial cell tumors, including non-small cell lung carcinoma (NSCLC), breast cancer, glioma, squamous cell carcinoma of the head and neck, colorectal cancer, rectal adenocarcinoma, head and neck cancer, stomach cancer and prostate cancer, and the activation of the EGFR-tyrosine kinase causes continuous cell proliferation, invasion of surrounding tissues, distant metastasis, and angiogenesis, and increases cell survival.

There are afatinib (GILOTRIF) and trastuzumab (HERCEPTIN), etc., as anticancer drugs that target HER2 and EGFR, but these anticancer drugs have problems in that cancer recurs after treatment or only some patient groups show reactivity. For example, in the case of trastuzumab, the following cases have been reported that about 11.6% of patients with HER2-overexpressing breast cancer who received conventional anticancer treatment are responsive to trastuzumab, and the remaining 88.4% of patients have no or weak response to trastuzumab (Baselga et al., J. Clin. Oncol. 14:737-744 (1996)).

As described above, there is an increasing unmet need for novel compounds capable of being usefully utilized in the treatment of HER2- and EGFR-related diseases by modulating HER2 and EGFR activities.

[Step-1] Preparation of methyl 4-(4-methoxy-3-nitrophenyl)thiophen-2-carboxylate

In 1,4-dioxane (0.1 M) and water (0.5 M), 4-bromo-1-methoxy-2-nitrobenzene (1.0 equiv.), (5-(methoxycarbonyl)thiophen-3-yl) boronic acid (2.0 equiv.), and K₃PO₄(2.2 equiv.) were dissolved, and degassed using nitro gas. Then, Xphos Pd G2 (0.13 equiv.) was added at 80° C., and the mixture was stirred at 100° C. for 1 hour. The reaction mixture was filtered through a celite filter, and concentrated.

<Experimental Example 2> Evaluation of SK-BR-3, BT-474, N-87, and HaCaT Cell Proliferation Inhibitory Activity

To evaluate the cell proliferation inhibitory activity of the compound according to the present invention on HER2 and EGFR kinases, the following method was performed using HER2 overexpressing cell lines (SK-BR-3, BT-474, and N-87) and EGFR expressing cell line (HaCaT).

McCOY'S 5A supplemented with 10% FBS was used for SK-BR-3 cells, RPMI-1640 medium supplemented with 20% FBS was used for BT-474 cancer cells, and RPMI-1640 medium supplemented with 10% FBS was used for N-87 cancer cells. DMEM supplemented with 10% FBS was used for HaCaT cells.

For SK-BR-3 cells, 5000 cells were aliquoted into each well of a white clear bottom 96 well plate (Corning) 48 hours before treatment with the compounds of Examples. For BT-474 cells, 5000 cells were aliquoted into each well of a white clear bottom 96 well plate (Corning) 48 hours before treatment with the compounds of Examples. For N-87 cells, 5000 cells were aliquoted into each well of a white clear bottom 96 well plate (Corning) 24 hours before treatment with the compounds of Examples. For HaCaT cells, 3000 cells were aliquoted into each well of a white clear bottom 96 well plate (Corning) 24 hours before treatment with the compounds of Examples. For SK-BR-3 cells and BT-474 cells, the compounds of Examples were diluted in dimethyl sulfoxide (three-fold dilution, a total of 11 concentrations) and injected each in an amount of 1 μl to a final concentration of 0.2 nM to 10 μM. For N-87 cells, the compounds of Examples were diluted in dimethyl sulfoxide (five-fold dilution, a total of 11 concentrations) and injected each in an amount of 0.5 μl to a final concentration of 0.5 μM to 5 μM. For HaCaT cells, the compounds of Examples were diluted in dimethyl sulfoxide (three-fold dilution, a total of 11 concentrations) and injected each in an amount of 0.5 μl to a final concentration of 0.8 nM to 45 μM. For the measurement of living cells, the cells were stored at room temperature for 10 minutes using CellTiter-Glo cell viability reagent (Promega) after a certain period of time (SK-BR-3: 120 hours, BT-474: 120 hours, N-87: 72 hours, and HaCaT: 72 hours) post treatment with the compounds of Examples, and the luminescence intensity thereof was measured using a reader (SynergyNeo, Biotek). Each test was repeated three times.

The result values were calculated as a cell growth rate (%) compared to those of the control group. A graph was created using the GraphPad Prism version 5.0 program, and GI₅₀values were calculated. Results thereof are shown in Table 14 below.

<Experimental Example 3> Evaluation of Transduced Ba/F3 Cell Proliferation Inhibitory Activity

For Ba/F3 cells, RPMI-1640 supplemented with 10% FBS and 5 ng/ml IL-3 (R&D Systems) was used. Transduced Ba/F3 cells were cultured by adding 1 μg/ml puromycin (Invitrogen) to the same medium.

3000 to 5000 cells were aliquoted into each well of a white clear bottom 96 well plate (Corning) 24 hours before treatment with the compounds of Examples. The compounds of Examples were diluted in dimethyl sulfoxide (three-fold dilution, a total of 12 concentrations) and injected each in an amount of 1 μl to a final concentration of 0.2 nM to 5 μM. For the measurement of living cells, the cells were stored at room temperature for 10 minutes using CellTiter-Glo luminescent cell-viability reagent (Promega) in 72 hours after treatment with the compounds of Examples, and the luminescence intensity thereof was measured using a reader (SynergyNeo, Biotek). Each test was repeated three times. The result values were calculated as a cell growth rate (%) compared to those of the control group. A graph was created using the GraphPad Prism version 8.3.0 program, and GI₅₀values were calculated.

Table 15 below shows the results of evaluating the Ba/F3 cell proliferation inhibitory activity of L869R, L756S, T798I, and T862A expressing HER2 rare or uncommon and drug-resistant mutations and G719A, L861Q, S768I, G719A/S768I, and Del19/T790M expressing EGFR rare or uncommon and drug-resistant mutations.
