BACKGROUND OF THE INVENTION
1. Field of the Invention

The present invention relates to a novel imidazopyridine derivative, a method for preparing the same, and a pharmaceutical composition containing the same as an active ingredient for preventing or treating cancer.


2. Description of the Related Art

Chronic myeloid leukemia (CML) is a kind of blood cancer which is developed by chromosome aberration in hematopoietic stem cells existing in bone marrow. That is, Bcr (breakpoint cluster region) gene on chromosome 22 and Abl (V-abl Abelson murine leukemia viral oncogene homolog) gene on chromosome 9 are crossed and inverted to form the Bcr-Abl tyrosine fusion tumor gene. The tyrosine kinase which is produced by the Bcr-Abl gene continues its activity to activate intracellular cell division related signal transduction system, resulting in hyperproliferation of leukocytes, and at the same time inhibits apoptosis related signal transduction, resulting in leukemia. P210-Bcr-Abl is known as a direct tumor factor causing chronic myeloid leukemia (CML).


Gleevec has an excellent therapeutic effect and safety, so that it has been widely used as the primary standard therapy for the treatment of chronic myeloid leukemia (CML). However, many of CML patients who had been treated with Gleevec display resistance, and recently, the variable species showing resistance have been confirmed. Gleevec resistance is caused by a point mutation that occurs at the active site of Bcr-Abl tyrosine kinase. For example, such mutations as T315I in which the 315th threonine is replaced with isoleucine and T253H in which the 253rd tyrosine is replaced with histidine are most frequent. Among the Gleevec resistant point mutations, T315I-Bcr-Abl is the most dominant.


The proliferation of cells having point mutations is not regulated by Gleevec anymore. The therapeutic effect is not any better even with increasing the dose of Gleevec.


The second generation anticancer agents that can treat Gleevec resistance are nilotinib (Tasigna) and dasatinib (Sprycel). However, their ability to inhibit the T315I-Bcr-Abl mutant is very weak. Since the activity of the existing second generation anticancer agents to inhibit mutant species is very weak, continuous study is still requested and also the development of a novel next generation anticancer agent capable of preventing or treating Gleevec resistance is highly requested as well.


In the meantime, RET (rearranged during transfection) is one of the receptor tyrosine kinases belonging to cadherin. RET tyrosine kinase has a transmembrane region in the center, a tyrosine kinase region in the carboxyl terminus, and an extracellular region in the amino terminus. Three types of proteins are present due to the difference of splicing in the carboxyl terminus.


RET forms a dimer mediated by the ligand/GFR complex, by which its tyrosine is phosphorylated, resulting in the activation of RET. When an abnormality occurs in RET gene (point mutation, chromosomal translocation, chromosome inversion, or gene amplification), it is involved in carcinogenesis. For example, in the case of thyroid cancer, a point mutation in RET gene is observed and thereby the expression of RET tyrosine kinase involved in carcinogenesis is confirmed. In the case of thyroid papillary carcinoma, RET gene is fused with CCDC6 gene (coiled-coildomain containing 6) or NCOA4 gene (nuclear receptor coactivator 4) by such a mutation in RET gene as chromosomal inversion or chromosomal translocation to express the fusion type tyrosine kinase RET/PTC which induces cancer. In the case of non small cell lung cancer, RET is fused with K1F5B gene (kinesin family protein 5B), one of the constituent molecules of the protein complex involved in microtubule transport in cells, or CCDC6 gene, and as a result, non small cell lung cancer is developed by the tyrosine kinase activity of the fusion type tyrosine kinase KIF5B-RET or CCDC6-RET.


Therefore, a compound having the activity of inhibiting RET tyrosine kinase is very useful for the prevention or treatment of cancer. It was reported that such multi-kinase inhibitors as Sorafenib, Sunitinib, XL184, Vandetanib and Ponatinib were able to inhibit cell proliferation in the cell line expressing KIF5B-RET (J Clin Oncol 30, 2012, suppl; Abstract no: 7510).


A fibroblast growth factor receptor (FGFR) tyrosine kinase is composed of approximately 800 amino acids and is a type 5 receptor tyrosine kinase having three kinds of immunoglobulin (Ig)-like domains (D1, D2 and D3). FGFR has largely 4 kinds of sub-types: FGFR1, FGFR2, FGFR3 and FGFR4.


Fibroblast growth factor (FGF) and its receptor (FGFR) are a part of unique and diverse signal transduction systems playing an important role in various physiological processes including embryogenesis and various aspects of adult pathophysiology. It is known that FGF stimulates broad cell functions including migration, proliferation, differentiation and survival by binding with FGFR.


The over-expression or mutation of FGFR can cause cancer (for example, bladder cancer, breast cancer, cervical cancer, colorectal cancer, endometrial cancer, stomach cancer, head and neck cancer, kidney cancer, liver cancer, lung cancer, ovarian cancer, and prostate cancer), hematopoietic malignant tumor (for example, multiple myeloma, chronic lymphocytic lymphoma, adult T-cell leukemia, acute myelogenous leukemia, non-Hodgkin's lymphoma, myeloproliferative neoplasm, and Waldenstrom's macroglubulinemia), glioblastoma, melanoma and rhabdoid tumor. FGFR gene fusion occurs in various types of cancer, and activation of FGFR signal transduction is known to promote cancer cell proliferation. Thus, efforts have been made to develop drugs targeting FGFR for the purpose of treating cancer.


In particular, numbers of in vivo and in vitro studies have been performed to identify FGFR1-FGFR 4 as important cancer targeting agents. However, effective drug development has not been achieved at a desired level so far, and thus continuous efforts are requested.


The present inventors tried to develop a drug to treat cancer or tumor that can overcome T315I resistance and inhibit Ret or FGFR efficiently. In the course of our study, the present inventors confirmed from the experiment with K562 (wild type Bcr-Abl) cell line that the compound of the present invention can overcome T315I resistance and inhibit Ret and FGFR efficiently and further inhibit the proliferation of cancer cells in a xenograft model efficiently. Thus, the present inventors confirmed that a pharmaceutical composition comprising the compound of the present invention as an active ingredient can be effectively used for the prevention or treatment of cancer, leading to the completion of the present invention.


The present inventors also confirmed that the compound of the present invention had an excellent activity to inhibit Src/Fyn enzyme involved in metabolic disease including diabetic nephropathy in addition to cancer. The representative disease involved in Src/Fyn enzyme is diabetic nephropathy (DN), which is one of major complications of diabetes along with retinopathy and neuropathy.


Most of the recent studies on diabetic nephropathy are focused on glomerular sclerosis due to proliferation and hypertrophy of mesangium or fibrosis caused by extracellular matrix accumulation of renal tubular epilepsy.


More recently, it has been suggested that the extracellular domain of nephrin can form a slit membrane and the tyrosine residue of the intracellular domain can be phosphorylated by Fyn belonging to src-kinase family to be involved in signal transduction in podocytes.


Previous studies are focused and progressed on the idea that Nck (non-catalytic region of tyrosine kinase adaptor protein 1) or PI3K (Phosphoinositide 3-kinase) having SH2 (Src homology 2) domain recognizes the phosphorylated region of nephrin so that it plays an important role in keeping the structure of podocytes by regulating actin cytoskeleton mediated by the recognition above. However, studies about the signal transduction and its regulators in podocytes via nephrin phosphorylation are still insufficient.


From the continued study, the present inventors confirmed that the compound of the present invention was very useful as a novel therapeutic agent for diabetic nephropathy and further the present inventors evaluated the pharmaceutical effect of the compound of the present invention by using urinary obstruction and diabetic-induced mouse models. As a result, to our surprise, the compound of the present invention was confirmed to be effective in preventing or treating diabetic nephropathy, leading to the completion of the present invention.

<Experimental Example 2> Evaluation of Cancer Cell Proliferation Inhibition (Cancer Cell Apoptosis) Activity

The following experiment was performed to evaluate the cancer cell proliferation inhibition (cancer cell apoptosis) activity of the compound of the present invention.


MTS assay was performed to evaluate the cancer cell proliferation inhibition (cancer cell apoptosis) effect of the compounds of examples of the present invention. Particularly, the assay was performed using the cancer cell lines GIST-T1, GIST-T1/816, GIST-430, GIST-430/654, GIST-R1, GIST-R3, M-NFS-60, RetParental (Ba/F3), Retwt (Ba/F3), RetV804M (Ba/F3), RET (LC2/ad-CDC6), FYN (MCP-1), FYN (FN), MDA-MB-231, Huh7, K562, T315I(Ba/F3), SK-MEL-28 and A375. Cell culture was performed using a medium suitable for each cell line.


More precisely, GIST-T1 (imatinib-sensitive, p.V560_Y578del (exon 11)), GIST-T1/816 (imatinib-resistant, p.V560_Y578del (exon 11), p.D816E (exon 17)), GIST-430 (imatinib-sensitive, p.V560_L576del (exon 11)), GIST-430/654 (imatinib-resistant, p.V560_L576del (exon 11), p.V654A (exon 13)) cell lines were seeded in each well of a 96-well flat bottom plate (SPL Life Sciences) at the density of 2×104/100 μl, while the GIST patient originated cell lines GIST-R1 (imatinib-resistant, p.W557_K558del (exon 11)) and GIST-R3 (imatinib/sunitinib-resistant, p.558_560KVV>1 (exon 11), p.Y823D (exon 17)) were seeded in each well of a 96-well white plate (Corning) at the density of 2×104/100 μl. On the next day, the compounds of examples of the present invention were treated thereto at 8 different concentrations. 72 hours later, cell survival rate was measured by using EZ-cytox cell viability kit (DAEIL Lab, Seoul, Korea) or CellTiter-Glo Luminescent cell viability assay (Promega) according to the manufacturer's protocol. Each experiment was performed twice independently. Data were presented as % by the vehicle treated cells and IC50 values were calculated by using GraphPad Prism 5.0 software (GraphPad software Inc., San Diego).


M-NFS-60 cell line was cultured in the complete growth medium prepared by adding 10% FBS, 0.05 mM 2-mercaptoethanol and 62 ng of human M-CSF to RPMI. When the confluence reached 80% in T-75 flask, the cells were collected in a 50 ml tube for seeding, followed by centrifugation at 800 rpm for 5 minutes. The cells were suspended in 10 mL of growth medium. The cell number was counted by using a hematocytometer to determine the necessary cell number and the medium volume for seeding. The cells were seeded in a 96-well plate at the density of 20000 cells/well (200 μL/well), followed by stabilization in a 37° C. CO2 incubator, while the compounds of the present invention were prepared. The compounds of the present invention were serially diluted with DMSO at the ratio of 1/3 with setting the maximum concentration at 1968 nM, which were loaded in a new V-bottom 96-well plate, resulting in the preparation of total 11 concentrations including the DMSO control. The cells that had been placed in the incubator were taken out, to which the compounds of the present invention were added (2 μl/well). The plate treated with the compounds was cultured in a 37° C. CO2 incubator for 72 hours. 72 hours later, the plate treated with the compounds was taken out, to which CCK-8 solution was treated (20 μl/well). After well mixing, the plate was further cultured in a 37° C. CO2 incubator for 2 hours. Then, OD450 was measured by using a microplate reader. To obtain accurate results, the wells displaying bubbles were eliminated from the measurement.


In the meantime, MDA-MB-231 and A375 cells were seeded in a 96well plate at the density of 2×103/100 μl/well, which stood for a day for attachment. The culture fluid was eliminated. After removing the culture medium, the medium was replaced with the culture medium containing the compounds of the present invention at 3-times serially diluted 9 concentrations (0.0015-10 μM) and the DMSO control, followed by incubation in a 37° C. CO2 incubator for 72 hours. On the other hand, K-562 and Ba/F3-T315I cells were seeded in a 96-well plate at the density of 1×104/90 μl/well. The plate containing K-562 cells was added with the culture medium containing the compounds of the present invention at 3-times serially diluted 9 concentrations (0.015-100 μM) and the DMSO control (10 μl/well). The plate containing Ba/F3-T315I cells was added with the culture medium containing the compounds of the present invention at 5-times serially diluted 9 concentrations (0.000256-100 μM) and the DMSO control (10 μl/well). The final concentration was made 0-10 μM and then the cells were cultured in a 37° C. CO2 incubator for 72 hours.


The real time cell proliferation of MDA-MB-231 was measured for 72 hours by using IncuCyte ZOOM® analyzer software and then IC50 was calculated using GraphPad Prism 6 software.


A375, K-562 and Ba/F3-T315I cells were added with CCK-8 solution at the concentration of 10 μl/well, followed by orbital shaking for 30 seconds. Then, the cells were cultured in a 37° C. CO2 incubator for 2 hours. OD450 was measured by using a microplate reader. The OD value of the well treated with the culture medium and CCK-8 solution alone was subtracted from the OD value measured above, followed by calculation of IC50 using GraphPad Prism 6 software.


Other cell lines were seeded in a 96-well plate containing the corresponding medium appropriate for each cell line at the density of 3,000 cells/well, followed by culture in a 5% CO2 and 37° C. incubator for 24 hours. The compounds of examples of the present invention were added to each well at the concentration of from the highest volume of 50 μM to every step of serial dilution. The solvent control, dimethylsulfoxide (DMSO), was treated at the same concentration of 0.05% (v/v) as the volume used for the treatment of the compounds above. Each cell line was cultured for 72 hours. To investigate the cell viability, the MTS and PMS (phenazine methosulfate) mixture provided in CellTiter 96® AQuous Non-Radioactive Cell Proliferation Assay Kit (Promega) was added to each cell culture medium, followed by additional culture at 37° C. for 2 hours. Then, OD450 was measured. Based on OD of the solvent control cells not treated with any compounds of the present invention, the cell proliferation inhibition rate was calculated according to the treatment concentration of each compound. At this time, the concentration of each compound that was able to inhibit cancer cell proliferation up to 50% was determined as IC50 (uM). IC50 of each compound was determined with three data sets and calculated by using Prism softwater (version 6.01, GraphPad).


The results of the experiments on each cell line described above are shown in Tables 4, 5 and 6, respectively.

Urine albumin and KIM-1 were measured by using ALPCO (Westlake, Ohio, USA) and R&D Systems (Minneapolis, Minn., USA) ELISA Kits, respectively.


Histological and Immunohistochemical (IHC) Observations


The right kidney was fixed in 2% paraformaldehyde-lysin-periodate (pH 7.4). After dehydration and hardening the kidney in paraffin, thin sections were made. Periodic acid-Schiff (PAS) staining was performed and 15 cortical glomeruli were randomly selected and photographed. The mean size of each glomerulus and fractional mesangial area (FAM) were measured. Standardized Masson's Trichrome staining was performed to confirm the collagen matrix deposition in the kidney, and IHC staining was performed using CD68 antibody to measure the chronic inflammatory response.


All the staining photographs were observed with a Zeiss microscope equipped with Axio Cam HRC digital camera and Axio Cam software (Carl Zeiss, Thornwood, N.Y., USA) and quantified using Image-Pro Plus4.5 software (Media Cybernetics).


Real Time Quantitative PCR


RNA was extracted by using TRIzol (Invitrogen, Carlsbad, Calif., USA). The expression of mRNA was quantified with Real-time PCR ABI7300 (Applied Biosystems, Carlsbad, Calif., USA) using cDNA transcripts, primer and SYBR Green PCR Master Mix (Applied Biosystems) mixture (20 μl). The primer sequences are shown in Table 1. The standardization was accomplished by using the house keeping gene 18S.

<Experimental Example 3-2> Experiment with Diabetes Induced White Mice

Male SD white mice at 6-7 weeks of age (Japan SLC Inc., Hamamatsu, Japan) were used. Streptozotocin (STZ, 60 mg/kg, intraperitoneally administered) was administered to the experimental animals to induce type I diabetes. The STZ non-treated control group was treated with sodium citrate buffer (sodium citrate 100 mM, citric acid 100 mM, pH 4.5). To investigate the therapeutic effect of the compound of example 11, the compound was orally administered to the experimental animals for 8 weeks from the beginning of diabetes induction. The effect was compared with that of losartan (1 mg/kg/d) that is an angiotensin receptor antagonist being used clinically as a drug to treat diabetic nephropathy. The diabetic control (treated with STZ alone) was administered with the solvent of Example 11, DMSO/Tween 70.DW (10:5:85).
