The present invention relates to a novel fused pyrimidine derivative having an inhibitory activity for tyrosine kinases, and a pharmaceutical composition comprising same as an active ingredient.
There are many signal transduction systems in cells which are functionally linked to each other to control the proliferation, growth, metastasis and apoptosis of cells (William G. Kaelin Jr., Nature Reviews Cancer 5, 689, 2005). The breakdown of the intracellular controlling system by genetic and environmental factors causes abnormal amplification or destruction of the signal transduction system leading to tumor cell generation (Douglas Hanahan and Robert A. Weinberg, Cell 100, 57, 2000).
Protein tyrosine kinases play important roles in such cellular regulation (Irena Melnikova and James Golden, Nature Reviews Drug Discovery 3, 993, 2004), and their abnormal expression or mutation has been observed in cancer cells or autoimmune diseases. The protein tyrosine kinase is an enzyme which catalyzes the transportation of phosphate groups from ATP to tyrosines located on protein substrates. Many growth factor receptor proteins function as tyrosine kinases to transport cellular signals. The interaction between growth factors and their receptors normally controls the cellular growth, but abnormal signal transduction caused by the mutation or overexpression of any of the receptors often induces various cancers or autoimmune diseases such as rheumatoid arthritis.
With regard to the roles of these tyrosine kinases, a variety growth factors and receptors thereof have been investigated, and among them, epidermal growth factors (EGF) and EGF receptor (EGFR) tyrosine kinases have been intensely studied (Nancy E. Hynes and Heidi A. Lane, Nature Reviews Cancer 5, 341, 2005). An EGFR tyrosine kinase is composed of a receptor and tyrosine kinase, and delivers extracellular signals to cell nucleus through the cellular membrane. Various EGFR tyrosine kinases are classified based on their structural differences into four subtypes, i.e., EGFR (Erb-B1), Erb-B2, Erb-B3 and Erb-B4, and it is known that EGFR activating mutations, such as L858R point mutation in exon 21 and in-frame deletions in exon 19 of the EGFR tyrosine kinase domain, are the important cause of non-small cell lung cancer.
Gefitinib (AstraZeneca) was initially developed as a small molecule for the inhibition of EGFR tyrosine kinases, which selectively and reversibly inhibits EGFR (Erb-B1). Erlotinib (Roche) has also similar characteristics. These EGFR-targeted drugs are efficacious for non-small cell lung cancer (NSCLC) and provide therapeutic convenience for patients with EGFR activating mutations.
However, it has been reported that the development of resistance lowers the activity of a particular drug used in EGFR-targeted therapies. It has been already reported that about half of the patients administered with Gefitinib or Erlotinib exhibited the resistance to the drugs due to the induction of the secondary EGFR T790M mutation (William Pao et al., Public Library of Science Medicine, 2(3), 225, 2005, Cancer Res, 67(24), 11924, 2007). Further, it has been recently found that irreversible inhibitors to target for EGFR are more beneficial in securing excellent efficacy and overcoming the resistance development, as compared to the conventional reversible inhibitors such as Gefitinib and Erlotinib (Danan Li et al., Cancer Cell 12, 81, 2007; and Anja Michalczyk et al., Bioorganic & Medicinal Chemistry 16, 3482, 2008). Hence, irreversible inhibitors such as BIBW-2992 (Afatinib, Boeringer Ingelheim) (C H Mom et al., British Journal of Cancer 98, 80, 2007), PF00299804 (Dacomitinib, Pfizer) (Engelman J A, et al., Cancer Res. 67, 11924, 2007), and AV-412 (AVEO Pharmaceuticals) (Tsuyoshi Suzuki et al., Cancer Sci. 98(12), 1977, 2007) have been developed and are currently in the clinical stage. The compounds have been known to form a covalent bond with Cystein773 (Cys773) positioned at an ATP domain of EGFR, thereby irreversibly blocking the autophosphorylation of EGFR and thus efficiently inhibiting the signal transduction of cancer cells (David W. Fry et al., Proc. Natl. Acad. Sci. U.S.A. 95, 12022, 1998), and exhibit higher inhibitory activities compared to the reversible inhibitors commercially available as dual inhibitors of EGFR/HER-2, or pan-HER inhibitors in in vitro activities and in various in vivo models of carcinomas (Jeff B. Smaill et al., J. Med. Chem. 42, 1803, 1999). However, the compounds may cause serious side effects such as skin rashes, diarrhea and weight loss due to high activities to EGFR WT (wild type) present in normal cells, when they are administered in a dose sufficient to overcome the resistance induced by EGFR T790M mutations, and this has been limited their clinical application, (Martin L. Sos, et al., Cancer Res. 70, 868, 2010).
As evidenced by clinical tests of the irreversible inhibitors in non-small cell lung cancer, the compounds have exhibited improved activities but still weak therapeutic effects in the resistance development of cancer patients, compared to the conventional reversible inhibitors. Accordingly, there has been a continued need to develop a novel drug that is effective in drug-resistant cancers and has no adverse side effects.
Meanwhile, there are various evidences that B-cells (B-lymphocytes) and T-cells (T-lymphocytes) play a key role in the pathogenesis of inflammatory diseases, autoimmune diseases and/or immunity mediated diseases.
For instance, aberrant signaling can induce deregulated B-cell proliferation and differentiation to cause all sorts of lymphoma including various acute or chronic lymphoid leukemia and can cause formation of autoantibodies that lead to multiple inflammatory diseases, autoimmune diseases and/or immunity mediated diseases.
Bruton's tyrosine kinase (BTK) is a member of the TEC family of tyrosine kinases, and plays an important role in B-cell activation and signal transduction. BTK plays an essential role in B-cell signaling pathway which links the B-cell receptor (BCR) stimuli on the surface of B-cells to the response in downstream cells. Further, BTK has been known to be a critical regulator of B-cell development and mature B-cell activation and survival (Khan et al., Immunity 3, 283, 1995; Ellmeier et al., J. Exp. Med. 192, 1611, 2000; Kurosaki, Current Opinion in Immunology 12, 276, 2000; Schaeffer and Schwartzberg, Current Opinion in Immunology 12, 282, 2000). Thus, inhibition of BTK could be a therapeutic approach to block B-cell mediated disease processes.
For example, it has been known that BTK-deficient mice are resistant to collagen-induced arthritis and BTK inhibitors have been demonstrated dose-dependent efficacies in a mouse model of arthritis (Jansson and Holmdahl, Clin. Exp. Immunol. 94, 459, 1993; Pan et al., Chem. Med. Chem. 2, 58, 2007). Thus, effective BTK inhibitors may be useful in the treatment of rheumatoid arthritis.
In addition, BTK is also expressed by cells other than B-cells that may be involved in disease processes, i.e., bone marrow-derived mast cells. It has been reported that the antigen-induced degranulation is suppressed in BTK-deficient bone marrow-derived mast cells (Iwaki et al., J. Biol. Chem. 280, 40261, 2005). This shows that BTK could be useful to treat pathological mast cell responses such as allergy and asthma.
Also, monocytes, in which BTK activity is absent, showed decreased TNF-α production following stimulation (Horwood et al. J Exp Med. 197, 1603, 2003). Therefore, TNF-α mediated inflammation could be modulated by BTK inhibitors.
Furthermore, BTK has been reported to play a role in apoptosis as some of regulators (Islam and Smith, Immunol. Rev. 178, 49, 2000). Thus, BTK inhibitors would be useful for the treatment of certain B-cell lymphomas and leukemias (Feldhahn et al., J. Exp. Med. 201, 1837, 2005).
Meanwhile, T-cells play a role in transmitting signals delivered through the T-cell receptor (TCR) on the cell surface from antigen presenting cells into downstream effectors by the activation of intercellular various kinases such as janus kinases. At this time, they secrete various interleukin (IL) or interferon-γ to activate various leukocytes as well as the B-cells. Protein kinases involved in signal transduction in T-cells are Janus kinases (JAK) such as JAK1, JAK2, JAK3 and TYK2, IL-2 inducible T-cell kinases (ITK), and TEC family of kinases such as resting lymphocyte kinases (RLK).
Janus kinases involving JAK3 have been widely investigated as a target for autoimmune and/or inflammatory diseases. Among them, unlike JAK2 involved in hematosis and erythrocyte homeostasis or JAK1 expressed in various tissues, JAK3 is expressed in lymphocytes and plays a very important role in signal transduction via various cytokines, i.e., IL-2, IL-4, IL-7, IL-9 and IL-15, which is more attractive (Flanagan et al, Journal of medicinal Chemistry, 53, 8468, 2010). According to animal studies, JAK3 plays a role in the maturation of B-cells and T-cells as well as in maintaining T-cell functions.
Therefore, JAK3 inhibitors may be useful in the treatment of rheumatoid arthritis, psoriasis, atopic dermatitis, lupus, multiple sclerosis, Type I diabetes and complications from diabetes, cancer, asthma, autoimmune thyroid disorders, ulcerative colitis, Crohn's disease, Alzheimer's disease, leukemia, and other indications where immunosuppression would be desirable, such as organ transplants or xeno transplantation (Pesu M, Laurence A, Kishore N, et al., Immunol Rev 223, 132, 2008.; Kawahara A, Minami Y, Miyazaki T, et al., Proc Natl Acad Sci USA 92, 8724, 1995; Nosaka T, van Deursen J M A, Tripp R A, et al., Science 270, 800, 1995; Papageorgiou Ac, Wikman L E K., et al., Trends Pharm Sci 25, 558, 2004).
Meanwhile, other TEC family of kinases also play an important role in T-cell activation (Pamela L. Schwartzberg, et al., Nature Reviews Immunology 5, 284, 2005). For example, deletion of ITK which is characteristically expressed in T-cells in mice led to decreased cell proliferation which is induced by stimulation via T-cell receptors and decreased secretion of various cytokines such as IL-2, IL-4, IL-5, IL-10 and IFN-γ (Schaeffer et al., Science 284, 638, 1999; Fowell et al., Immunity 11, 399, 1999; Schaffer et al., Nature Immunology 2, 1183, 2001).
In addition, in ITK-deficient mice, immune symptoms of allergic asthma were attenuated and lung inflammation, eosinophil infiltration, and mucous production in response to challenge with the allergen ovalbumin were drastically reduced (Muller et al., Journal of Immunology 170, 5056, 2003). This shows that ITK inhibitors would be useful in the treatment of asthma.
Further, ITK has also been implicated in atopic dermatitis. This gene has been reported to be more highly expressed in peripheral blood T-cells from patients with severe atopic dermatitis, compared with controls or patients with mild atopic dermatitis (Matsumoto et al., International archives of Allergy and Immunology 129, 327, 2002).
Meanwhile, RLK functions to activate the secretion of IL-2 which is produced by signal transduction of T-cell receptors of splenocytes. Thus, the inhibition of RLK may reduce various responses by T-cells (Schaeffer et al., Nature Immunology 2, 1183, 2001; Schaeffer et al., Science 284, 638, 1999).
In addition, bone marrow tyrosine kinase (BMX) has been known to be involved in epithelial and endothelial cell migration (Pan et al., Mol. Cell. Biol. 2002, 22, 7512). Therefore, BMK inhibitors may be developed as anticancer agents for inhibiting the metastasis of cancer cells and angiogenesis.
As above, since TEC family kinases such as BTK, ITK, RLK, BMX and others and Janus kinases such as JAK3 play a critical role in the activation of B-cells and/or T-cells which is implicated in the pathogenesis of inflammatory diseases, autoimmune diseases, and immunologically mediated diseases, a compound for effectively inhibiting the kinases may be useful as a therapeutic agent for various inflammatory diseases, autoimmune diseases, and immunity mediated diseases.
Furthermore, a compound for inhibiting BTK involved in B-cell activation inducing B-cell lymphoma, and BMX involved in metastasis of cancer cells may be useful as an anticancer or antitumor agent.
Therefore, the development of a compound, which can inhibit above kinases and selectively inhibit variant EGFRs such as secondary T790M mutations as well as L858R point mutation at exon 21 or in-frame deletion at exon 19, is one of very important challenges.
Even though it was suggested that EGFR irreversible inhibitors, which form a covalent bond with Cystein773 (Cys773) positioned at an ATP domain of EGFR, may show inhibitory effects on the activities of TEC family of kinases such as BTK, ITK, RLK and BMX in which cysteine is present in a same position of the amino acid sequence, as well as kinases such as JAK3 or BLK (Wooyoung Hur, et al., Bioorg. Med. Chem. Lett. 18, 5916, 2008), there has been no developed for a compound which can inhibit irreversibly, selectively and effectively variant EGFR, BTK, JAK3, ITK, RLK, BMX and/or BLK.
Therefore, it is an object of the present invention to provide a novel fused pyrimidine derivative which selectively and effectively inhibits cancers or tumors induced by an epidermal growth factor receptor (EGFR) tyrosine kinase or a mutant thereof with reduced adverse side effects.
It is another object of the present invention to provide a novel fused pyrimidine derivative which can treat cancers, tumors, inflammatory diseases, autoimmune diseases, or immunologically mediated diseases mediated by abnormally activated B-lymphocytes, T-lymphocytes or both, by repressing non-receptor tyrosine kinases such as TEC family kinases (e.g. BTK, ITK, BMX or RLK) and janus kinases (e.g. JAK3).
It is still another object of the present invention to provide a pharmaceutical composition for preventing or treating cancers, tumors, inflammatory diseases, autoimmune diseases, or immunologically mediated diseases which comprises said novel fused pyrimidine derivative.

In order to identify that the inventive compounds obtained in Examples 1 to 237 selectively inhibit on the growth of the cancer cell expressing EGFR mutants compared than EGFR WT, the inhibiting test of the inventive compounds on the cancer cell growth was conducted as follow. For the test, a skin cancer cell line, A431 overexpressing EGFR wild-type (WT), a lung cancer cell line, HCC827 whose in-frame is deleted at position 19 exon in EGFR tyrosine kinase, and NCI-H1975 expressing EGFR L858R/T790M mutant which have resistance to the approved EGFR inhibitors such as Gefitinib or Erlotinib were employed.
The inhibiting test of the inventive compounds on the cancer cell growth was conducted in A431 (ATCC CRL-1555), HCC827 (ATCC CRL-2868) and NCI-H1975 (ATCC CRL-5908) cell lines.
A431 cell line was incubated in a high-glucose DMEM (Dulbecco's Modified Eagle's Medium) supplemented with 10% fetal bovine serum (FBS) and 1% penicillin/streptomycin (Gibco BRL), and HCC827 and NCI-H1975 cell lines were incubated in an RPMI medium supplemented with 10% FBS, 1% penicillin/streptomycin and 1% sodium pyruvate.
The cancer cell lines stored in a liquid nitrogen tank were each quickly thawed at 37° C., and centrifuged to remove the medium. The resulting cell pellet was mixed with a culture medium, incubated in a culture flask at 37° C. under 5% CO2 for 2 to 3 days, and the medium was removed. The remaining cells were washed with DPBS (Dulbecco's Phosphate Buffered Saline) and separated from the flask by using Tripsin-EDTA. The separated cells were diluted with a culture medium to a concentration of 1×105 A431 cells/ml, except that in case of HCC827 and NCI-H1975 cells, the dilution was carried out to 5×104 cells/ml. 100 μl of the diluted cell solution was added to each well of a 96-well plate, and incubated at 37° C. under 5% CO2 for 1 day. NCI-H1975 cells were starved in a RPMI-1640 medium containing 0.1% FBS and 1% penicillin/streptomycin to maximize the reacting activities of the cell on the test compounds on the following day.
The compounds obtained in Examples 1 to 237 were each dissolved in 99.5% dimethylsulfoxide (DMSO) to a concentration of 25 mM. In case that the test compound was not soluble in DMSO, 1% HCl was added thereto and treated in a 40° C. water bath for 30 mins until a complete dissolution was attained. The DMSO solution containing test compound was diluted with a culture medium to a final concentration of 100 μM, and then diluted 10 times serially to 10−6 μM (a final concentration of DMSO was less than 1%).
The medium was removed from each well of the 96-well plate. And then, 100 μl of a test compound solution was added to each well holding the cultured cells, and the plate was incubated at 37° C. under 5% CO2 for 72 hours (except that NCI-H1975 cells were incubated for 48 hours). After removing the medium from the plate, 50 μl of 10% trichloroacetic acid was added to each well, and the plate was kept at 4° C. for 1 hour to fix the cells to the bottom of the plate. The added 10% trichloroacetic acid solution was removed from each well, the plate was dried, 100 μl of an SRB (Sulforhodamine-B) dye solution at a concentration of 0.4% dissolved in 1% acetic acid was added thereto, and the resulting mixture was reacted for 10 mins at room temperature. After removing the dye solution, the plate was washed with water, and well dried. When the dye solution was not effectively removed by water, 1% acetic acid was used. 150 μl of 10 mM trisma base was added to each well, and the absorbance at 540 nm wavelength was determined with a microplate reader. In case of NCI-H1975, the cell viabilities were determined as the absorbance at 490 nm wavelength using Celltiter 96 Aqueous One solution (MTS, promega).
GI50, the concentration at which 50% inhibition occurs, was evaluated based on the difference between the final density of the test cells and the initial density of the cells incubated in a well not-treated with the test compound which was regarded as 100%. The calculation of GI50 and the result analysis were carried out by using Microsoft Excel, and the results are shown in Tables 14a to 14f. Wherein, A means that GI50≦50 nM, B means that GI50 is 50-100 nM, C means that GI50 is 100-1,000 nM, and D means that GI50≧1,000 nM.
As shown in Tables 14a to 14f, almost of the inventive compounds showed an excellent anticancer activity by selectively inhibiting the growth of the HCC827 and NCI-H1975 non-small cell lung cancer (NSCLC) cells expressing EGFR mutants (GI50=A or B), with no anticancer activity on A431 cell expressing EGFR WT (GI50=D). Such the inhibition mechanisms of the inventive compounds are very different from those of the commercially marketable EGFR tyrosine kinases (e.g., Erlotinib and Lapatinib) or the being developed material (BIBW2992).
As shown in Table 14f, Erlotinib as the first generation EGFR inhibitor was very effective in inhibiting the growth of NSCLC cell lines expressing EGFR mutants (HCC827, GI50=A), while it provided no inhibition activity against NSCLC cell lines expressing EGFR T790M point mutation (NCI-H1975, GI50=D). Also, the currently marketable Lapatinib which inhibits both EGFR and HER-2 showed a weak inhibition activity (HCC827, GI50=C) or no inhibition activity (NCI-H1975, GI50=D) against NSCLC cell lines. Further, the irreversible inhibitor having quinazoline structure, BIBW2992 (Boehringer Ingelheim, currently in the phase III stage, exhibited a strong inhibition activity against pan-HER and effectively inhibited all the cancer cell lines disclosed in Tables 14a to 14f including A431 cell line (GI50=A). However, such irreversible inhibitor having the quinazoline structure may cause serious adverse side effects (e.g., diarrhea, skin rash and weight loss) when treated in an amount for inhibiting EGFR T790M, and therefore, there still has been a need to develop a safe drug for overcoming the problems of the resistance development of EGFR T790M. Therefore, the inventive compounds showed a highly improved inhibition activity against EGFR mutants including EGFR T790M, with no inhibition activity against EGFR WT expressed in normal cell, which suggests that the inventive compounds can be used as more effective and safe anticancer drugs to NSCLC patients.
The inhibiting activities of the inventive compounds obtained in Examples 1 to 237 against EGFR WT and EGFR L858R/T790M kinase were determined using z-lyte kinase assay kit (Invitrogen, PV3191). The kinases used in the test were purchased from Invitrogen.
The compounds obtained in Examples 1 to 237 were each prepared to 10 mM DMSO solution, and a solution containing 4% DMSO were prepared therefrom and diluted to a concentration of 1 μM to 0.0001 μM. Then, an approximate Kd value of each kinase was calculated, and diluted using a kinase buffer (50 mM HEPES (PH 7.4), 10 mM MgCl2, 1 mM EGTA and 0.01% BRIJ-35) to 1 to 100 ng/assay concentration. The test was conducted in a 384 well polystyrene flat-bottomed plates. 5 μl of the diluted solution of each compound was added to each well, and 10 μl of a mixture of peptide substrate and kinase in a suitable concentration and 5 μl of 5-300 μM ATP solution were successively added thereto and the plate was incubated in a stirrer at room temperature for 60 minutes. After 60 mins, 10 μl of coloring reagent was added to the resulting mixture to initiate a fluorescence reaction of peptide substrate and a terminating solution was added thereto for terminating the reaction. A fluorescence value of each well was determined with a fluorescence meter (Molecular Device) at 400 nm (excitation filter) and 520 nm (emission filter). The inhibiting activity of the test compounds against the kinases was determined as a phosphorylation percentage (%) compared with control group, according to the kit protocol, and measured for IC50, the concentration of x-axis at which 50% inhibition was observed. The calculation of IC50 and the result analysis were carried out by using Microsoft Excel. The results are shown in Table 15. Wherein, A means that IC50≦50 nM, B means that IC50 is 50-100 nM, C means that IC50 is 100-1,000 nM, and D means that IC50≧1,000 nM.
As shown in Table 15, the inventive compounds showed a relatively low inhibition activity against EGFR WT related with the adverse effects (IC50=C or D), while it showed an excellent inhibition activity against EGFR L858R/T790M mutants having a resistance to the commercially marketable EGFR inhibitors (IC50=A). Like the results from Test Example 1, such the inhibition mechanisms of the inventive compounds are very different from those of the commercially marketable EGFR tyrosine kinases (e.g., Erlotinib and Lapatinib) or the being developed material (BIBW2992) which strongly inhibit EGFR WT (IC50=A or B). Therefore, the inventive compounds are effective and safe drug employable to NSCLC patients by showing an effectively excellent inhibition activity against EGFR mutants including EGFR T790M with no inhibition activity against EGFR WT expressed in normal cell.
The inhibiting activities of the inventive compounds obtained in Examples 1 to 237 against BTK and JAK3 kinases were determined, respectively. The procedure of Test Example 2 was repeated except that BTK and JAK3 kinases (Invitrogen) were employed instead of using the EGFR kinase. The results are shown in Tables 16a to 16c. Wherein, A means that IC50≦50 nM, B means that IC50 is 50-100 nM, C means that IC50 is 100-1,000 nM, and D means that IC50≧1,000 nM.
As shown in Tables 16a to 16c, the inventive compound showed an excellent inhibition activity against BTK and JAK kinases (IC50=A or B).
The compound obtained in Example 1 was measured for its inhibitory activity on TEC family kinases, i.e., BMX, ITK, TEX and RLK. The measurement was carried out in the same process as in Example 2, except for using BMX, ITK, TEC and RLK enzymes (Invitrogen) instead of EGFR enzyme. The results are shown in Table 17. The letter ‘A’ in the table means IC50≦50 nM, ‘B’ means IC50=50-100 nM, ‘C’ means IC50=100-1,000 nM, and ‘D’ means IC50≧1,000 nM.
As shown in Table 17, the compound of Example 1 according to the present invention effectively inhibited TEC family kinases such as BTK, BMX, ITK, and RLK kinases (IC50=A or B).
The compound according to the present invention (Example 2) was tested for its anticancer effect and toxicity in nude mice xenografted with NCI-H1975 cancer cells which shows resistance to Erlotinib previously approved for the treatment of non-small cell lung cancer, due to the acquisition of EGFR T790M point mutation. In order to evaluate the anticancer efficacy and toxicity of the compound according to the present invention, BIBW2992 (Boehringer Ingelheim), which currently exhibits excellent activity to resistant non-small cell lung cancer and is actively under development, was also used in the test.
NCI-H1975 cell (lung cancer cell) was purchased from American Type Culture Collection (ATCC). After formation of tumor by subcutaneous injection with 1×108 cells/0.3 mL of tumor cell suspension on the back of mice, passages were carried out and tumor in at least third generation was used in the test.
In the test, a tumor in the sixth generation isolated from an individual was cut into a size of 30 mg, and transplanted subcutaneously into right flanks of mice using a 12-gauge trocar. The volume of tumor (V) is calculated from following equation 1 after measuring a long diameter (L) and a short diameter (S) using a vernier caliper twice a week for 18 days of test. All test materials were orally administered one time a day for total 10 days, and the tumor growth inhibition rate (IR: tumor growth inhibition rate (%) calculated based on a vehicle-treated control) and the maximum body weight loss (mBWL: maximum body weight loss calculated based on the body weight just before administration) were calculated using following equations 2 and 3. The results are shown in Table 6 and
V=L×S2/2 <Equation 1>
wherein, L is a long diameter and S is a short diameter.
IR (%)=(1−(RTG of the treatment group of test material)/(RTG of the control group))×100 <Equation 2>
wherein, RTG is a relative tumor growth, which is the mean tumor volume on a particular day based on daily mean tumor volume.
mBWL (%)=(1−(mean body weight on day x/mean body weight just before administration))×100 <Equation 3>
wherein, day x is a day on which the body weight loss is largest during the test.
Following Table 18 is the results of IR and mBWL in an NCI-H1975 in vivo model.
1)measured on 16th day after administration;
2)measured on 10th day after administration.
The compound of the present invention did not inhibit EGFR WT and exhibited an excellent activity on EGFR mutant specific to non-small cell lung cancer (active mutant: EGFR DelR746_A750, EGFR L858R; acquired mutation: EGFR T790M). As shown in Table 18 and
In order to evaluate the efficacy of the compound according to the present invention for rheumatoid arthritis, the compound was subjected to arthritis inhibition test in a collagen-induced arthritis (CIA) model. The CIA model is a widely used, representative autoimmune arthritis model, arthritis of which is induced by injecting a mixture of type II collagen and an immunologic adjuvant to a specific mouse strain having major histocompatability complex (MHC) class II with H-2q or H-2r and thus CD4+ T cells and B-cells specifically responsive to the type II collagen are abnormally activated.
Male DBA/1J mice (8 weeks old) were first immunized by intradermal injection of 0.7 mL of a suspension liquid in which an equal volume of 2 mg/mL of type II collagen is emulsified in 4 mg/mL of complete Freund's adjuvant supplemented with bacteria tuberculosis. After 21 days, the mice were second immunized by the injection as above, except for using a suspension liquid in which an equal volume of 2 mg/mL of type II collagen is emulsified in incomplete Freund's adjuvant containing no bacteria tuberculosis. After 1 week of second immunization, mice were evaluated for clinical scores based on Table 19 and seven animals were grouped such that the average of experimental group is between 1 and 2. Test samples and vehicle of given concentrations were orally administered in an amount of 10 mL per body weight for 14 days everyday by using a Sonde. The clinical scores of arthritis (David D Brand et al., Nature Protocol. 2(5), 1269, 2007) were evaluated three times a day.
The compound of Example 1 reduced edema and flare until the last day (14 days) of the test in 10 mg/kg and 30 mg/kg groups compared to a control group, and significantly reduced edema, inflammation and flare in a 30 mg/kg group (
As shown in Tables 16a, 16b and 16c and
In addition, the compound according to the present invention significantly reduced the secretion of interleukin-6 (IL-6) and TNF-α in human peripheral blood mononuclear cells (PBMCs) and mouse splenocytes abundant in T-lymphocytes, B-lymphocytes, Cytes and macrophages after treatment of phorbol-12-myristate-13-acetate (PMA), phytohemagglutinin (PHA), lonomycin, and others which stimulate lymphocytes, compared to a control group. This demonstrates that the compound according to the present invention inhibits the activation of lymphocytes.
While the invention has been described with respect to the above specific embodiments, it should be recognized that various modifications and changes may be made to the invention by those skilled in the art which also fall within the scope of the invention as defined by the appended claims.
