TECHNICAL FIELD [0001] The present invention relates to a preventive and/or therapeutic agent of immune diseases, particularly, a preventive and/or therapeutic agent of allergic diseases or autoimmune diseases, comprising a novel fused pyrimidine compound or a salt thereof which has Bruton's tyrosine kinase (BTK) inhibitory effect, as an active ingredient. BACKGROUND ART [0002] It is known that various protein kinases exist in vivo and are involved in the regulation of a variety of functions. Bruton's tyrosine kinase (BTK) is a protein kinase that belongs to Tec kinase family, which is expressed in myeloid cells such as B-cells, monocyte/macrophages, neutrophils, mast cells and osteoclasts, and is involved in regulating functions of these cells (Non-Patent Literatures 1 and 2). BTK is located in the downstream of the immunereceptor signals such as B-cell receptor (BCR) or Fc receptor (FcR) family, being involved in the proliferation, survival, differentiation and activation of B-cells, and involved in regulating expression of inflammatory cytokines (for example, tumor necrosis factor-α or interleukin-1β) or chemical mediators (for example, histamine or leukotriene) in monocyte/macrophage or in mast cells (Non-Patent Literature 3). An inhibitor capable of regulating BTK activity is considered to be useful as a therapeutic agent for diseases associated with abnormal hyperactivity of BTK signaling pathway (for example, cancer, allergic diseases, or autoimmune diseases). [0003] In recent years, it has been considered that, in addition to B-cells which are involved in antibody production, various cells such as monocytes/macrophages, neutrophils, mast cells and osteoclasts, which express Fc receptor (FcR) family or its related molecules, are closely associated with incidence or progress of autoimmune diseases such as rheumatoid arthritis (Non-Patent Literature 4). Since BTK signals are associated with activation of these cells or abnormal activation of functions thereof (Non-Patent Literatures 2 and 3), it is expected that a compound with BTK inhibitory effect has a therapeutic efficacy against autoimmune diseases. In addition, since BTK is also involved in activation of mast cells, it is expected that a compound with BTK inhibitory effect has a therapeutic efficacy against allergic diseases with which B-cells or mast cells are associated. [0004] Currently known BTK inhibitors include PCI-32765 (Non-Patent Literature 5) and the compounds described in Patent Literatures 1 and 2 (Patent Literatures 1 and 2). The PCI-32765 is known to inhibit EGFR as well as BTK, and to be a compound useful as a therapeutic agent for immune diseases (such as rheumatoid arthritis) (Non-Patent Literature 5). [0005] Meanwhile, it is known that EGFR binds to, for example, epidermal growth factor (EGF) which is a ligand, and participates in the proliferation and survival (for example, inhibition of apoptosis) of various cells (Non-Patent Literature 6). It is known that inhibitors targeting EGFR cause adverse effects such as skin disorders and gastrointestinal dysfunction in common, and it is widely supposed that these adverse effects may be related to the inhibition of the wild type EGFR signaling pathway (Non-Patent Literature 7), and therefore, an inhibitor which has a high BTK selectivity and is highly useful has been desired as a preventive and/or therapeutic agent of immune diseases.

Nature Reviews Clinical Oncology. 9, 2012 SUMMARY OF INVENTION Technical Problem [0015] If the inhibitory activities against BTK and EGFR are separated from each other, it is possible to expect reduction of the adverse effects as mentioned above. [0016] That is, from the viewpoint of reducing adverse effects, a preventive and/or therapeutic agent of immune diseases that has a high inhibitory activity against BTK with low inhibitory activities against other kinases such as EGFR, which is at the same time excellent in efficacy, has been desired. [0017] Thus, an object of the present invention is to provide a preventive and/or therapeutic agent of immune diseases having a better effect against immune diseases than that of a conventional BTK inhibitor with reduced adverse effects, particularly, a preventive and/or therapeutic agent of allergic diseases or autoimmune diseases. Solution to Problem [0018] As a result of extensive researches, the inventors of the present invention have found that compounds represented by the following general formula (I) exhibit an excellent inhibitory activity against BTK and an excellent selectivity for BTK, and are useful as a medical drug for treating autoimmune diseases such as rheumatoid arthritis or systemic lupus erythematosus, or immune diseases such as allergic disease, for example, atopic dermatitis, and have accomplished the present invention. [0019] Specifically, the present invention provides a preventive and/or therapeutic agent of immune diseases which comprises the compound represented by the following general formula (I), or a salt thereof as an active ingredient: [0000] [0000] where X represents a nitrogen-containing C3-C10 heterocycloalkylene which may have one or more substituents; [0020] Y represents —C(R 4 )═C(R 5 )(R 6 ) or —C≡C—R 7 ; [0021] W and Z each independently represent N or CH; [0022] n represents an integer from 0 to 2; [0023] R 1 represents an amino group which may have one or more substituents; [0024] R 2 and R 3 , which may be identical or different, each represent a hydrogen atom, a halogen atom, a C1-C6 alkyl group which may have one or more substituents, a C1-C6 alkoxy group which may have one or more substituents, a C3-C7 cycloalkyl group which may have one or more substituents, a C6-C14 aromatic hydrocarbon group which may have one or more substituents, a 4-to 10-membered monocyclic or polycyclic unsaturated heterocyclic group containing 1 to 3 heteroatoms of the same kind or different kinds selected from the group consisting of a nitrogen atom, an oxygen atom and a sulfur atom, which heterocyclic group may have one or more substituents, or a cyano group; and [0025] R 4 , R 5 , R 6 and R 7 , which may be identical or different, each represent a hydrogen atom, or a C1-C6 alkyl group which may have one or more substituents.

[0029] As mentioned above, the PCI-32765 is known as a BTK inhibitor, and characterized by having a phenoxyphenyl group; however, it is significantly different from the compound of the present invention in view of lacking a benzoxazole group or an oxazolopyridine group, which represents a feature of the compound of the present invention. Furthermore, the compound of the present invention is characterized by having a higher BTK selectivity than that of PCI-32765 (Reference compound 1), as described later. [0030] Furthermore, the compounds described in Patent Literatures 1 and 2 also lack the benzoxazole group or the oxazolopyridine group, which is a feature of the compound of the present invention, and their structures are significantly different. [0031] Furthermore, the compound disclosed in WO 2007/067781 is known. [0032] However, the compounds disclosed therein are those which inhibit aurora kinases, and there is no disclosure of any specific compound having a benzoxazole group or an oxazolopyridine group. The Literature is also silent on the presence or absence of the BTK inhibitory activity or usefulness of a preventive and/or therapeutic agent of immune diseases. Advantageous Effects of Invention [0033] According to the present invention, provided is a preventive and/or therapeutic agent of immune diseases, particularly, allergic diseases or autoimmune diseases, which contains a novel compound represented by the above formula (I) or a salt thereof, which is useful as a BTK inhibitor, as an active ingredient. [0034] It has been made clear that the compound of the present invention or a salt thereof has an excellent BTK inhibitory activity and exhibits an excellent efficacy in an immunological disease model. Furthermore, since the compound of the present invention or a salt thereof strongly inhibits BTK selectively over EGFR, adverse effects can be reduced, and enhancement of safety can be expected. Therefore, the compound of the present invention or a salt thereof is useful as a preventive and/or therapeutic agent of immune diseases, particularly, as a preventive and/or therapeutic agent of allergic diseases or autoimmune diseases.

[0350] In general formula (VII), the leaving group represented by L 3 is a bromine atom or an iodine atom, and regarding the relevant compound, a commercially available product may be used, or the compound can be produced according to a known method.

The reaction temperature may be from 0° C. to a temperature at which the solvent boils, and preferably from 0° C. to 150° C. [0355] After this reaction, since a mixture of the carboxylic acid compound (VIII) and an ester form corresponding to the alcohol used is obtained, a hydrolysis reaction is conducted in order to converge the mixture into the compound represented by general formula (VIII).

Inhibitory Activity (In Vitro) [0592] Regarding the setting of the conditions for a method for measuring the inhibitory activity of a compound against BTK kinase activity in vitro, it is described in the consumable reagent supplies price list for LabChip (registered trademark) series of PerkinElmer, Inc. that FL-PEPTIDE 2 corresponds to a substrate peptide for the measurement of BTK kinase activity. Therefore, FL-PEPTIDE 2 was used as a substrate. The purified recombinant human BTK protein used in the test was purchased from Carna Biosciences, Inc. [0593] Regarding the measurement of the inhibitory activity of the compounds, firstly, the compounds of the present invention were diluted stepwise with DMSO. Subsequently, BTK protein, a substrate peptide (final concentration was 1 μM), magnesium chloride (final concentration was 10 mM), ATP (final concentration was 45 μM), and a DMSO solution of the compounds of the present invention (final concentration of DMSO was 5%) were added to a buffer solution for kinase reaction (20 mM HEPES (pH 7.5), 2 mM dithiotheitol, 0.01% Triton X-100), and after the solution was incubated for 40 minutes at 25° C., a kinase reaction was carried out. The reaction was terminated by adding EDTA thereto so as to obtain a final concentration of 30 mM. Finally, a substrate peptide that was not phosphorylated (S) and a phosphorylated peptide (P) were separated and detected by microchannel capillary electrophoresis with a LabChip EZ Reader II (PerkinElmer, Inc.). The amounts of phosphorylation reaction were determined from the respective peak heights of S and P, and the compound concentration at which the phosphorylation reaction could be suppressed by 50% was defined as the IC50 value (nM). The results are shown in Table 15 to Table 17 below.

Test Example 2 BTK Inhibition Selectivity Compared with EGFR Kinase Inhibitory Activity (In Vitro) [0595] 1) Measurement of BTK Inhibitory Activity [0596] The BTK inhibitory activity was measured in the same manner as in Test Example 1. [0597] 2) Measurement of EGFR Inhibitory Activity [0598] Regarding the setting of the conditions for a method for measuring the inhibitory activity of a compound against EGFR kinase activity in vitro, it is described in the consumable reagent supplies price list for LabChip (registered trademark) series of PerkinElmer, Inc. that FL-PEPTIDE 22 corresponds to a substrate peptide for the measurement of EGFR kinase activity. Therefore, a biotinated peptide (biotin-EEPLYWSFPAKKK) was produced by referring to the amino acid sequence of the peptide. The purified recombinant human EGFR protein used in the test was purchased from Carna Biosciences, Inc. [0599] Regarding the measurement of the inhibitory activity of the compounds, firstly, the compounds of the present invention were diluted stepwise with DMSO. Subsequently, EGFR protein, a substrate peptide (final concentration was 250 nM), magnesium chloride (final concentration was 10 mM), manganese chloride (final concentration was 10 mM), ATP (final concentration was 1.5 μM), and a DMSO solution of the compound of the present invention (final concentration of DMSO was 2.5%) were added to a buffer solution for kinase reaction (20 mM HEPES (pH 7.5), 2 mM dithiotheitol, 0.01% Triton X-100), and after the solution was incubated for 120 minutes at 25° C., a kinase reaction was carried out. The reaction was terminated by adding EDTA thereto so as to obtain a final concentration of 24 mM. Subsequently, a detection liquid containing Eu-labeled anti-phosphorylated tyrosine antibody PT66 (PerkinElmer, Inc.) and SureLight APC-SA (PerkinElmer, Inc.) was added thereto, and the system was left to stand for 2 hours or longer at room temperature. Finally, the amount of fluorescence upon irradiation with excitation light having a wavelength of 337 nm was measured at two wavelengths of 620 nm and 665 nm, with a PHERAstar FS (BMG Labtech GmbH). The amount of phosphorylation reaction was determined from the ratio of the amounts of fluorescence at the two wavelengths, and the compound concentration at which the phosphorylation reaction could be suppressed in 50% was defined as the IC50 value (nM). [0600] 3) BTK Inhibition Selectivity [0601] The “EGFR inhibitory activity IC50 value (nM)/BTK inhibitory activity IC50 value (nM)” was calculated on the basis of the results obtained in the above sections 1) and 2), and thereby the BTK inhibition selectivity of the test compound was identified. [0000] TABLE 18 EGFR inhibitory activity IC50 value (nM)/BTK Example inhibitory activity IC50 No. value (nM) 4 929.2 5 241.0 6 33.3 8 22.9 9 28.4 11 1294.6 12 84.2 13 28.8 14 128.1 15 145.0 16 158.1 17 157.2 18 121.3 19 144.8 20 138.2 21 147.4 22 260.1 25 173.7 26 642.8 30 21.3 32 43.1 33 43.4 34 79.3 35 35.1 36 59.8 [0000] TABLE 19 EGFR inhibitory activity IC50 value (nM)/BTK Example inhibitory activity IC50 No. value (nM) 37 70.5 39 37.5 40 10.0 42 19.4 44 17.1 47 20.4 49 24.8 50 22.1 51 31.1 52 20.6 53 25.5 54 37.1 56 17.6 57 19.3 58 23.5 59 16.3 60 32.4 61 67.5 Reference 1.3 compound 1 [0602] From these test results, it was made clear that the selectivity of the compound of the present invention to BTK inhibition over EGFR kinase in vitro was about 7.5 times or more compared with that of the Reference compound 1, and the compounds of the present invention have an excellent BTK inhibition selectivity. These results show that the compounds of the present invention can reduce adverse effects compared with existing BTK inhibitors. Test Example 3 Test for Measuring Proliferation Inhibitory Activity Against Cell Lines Expressing BTK and EGFR (In Vitro), and Comparison of its Selectivity [0603] TMD8 cells, which are of a diffuse large B-cell lymphoma cell line expressing BTK, were suspended in RPMI1640 medium (Life Technologies Corp.) containing 10% fetal bovine serum. A431 cells, which are of an EGFR-overexpressing, highly activated human epidermoid carcinoma cell line, were suspended in DMEM, high glucose medium (Life Technologies Corp.) containing 10% fetal bovine serum. The cell suspensions were inoculated into each well of 384-well flat-bottomed microplates, and the cells were cultured for one day at 37° C. in an incubator containing 5% carbon dioxide gas. The compounds of the present invention and Reference compound 1 were each dissolved in DMSO, and the solutions were diluted to a concentration of 500 times the final concentration of the test compound with DMSO. A DMSO solution of the test compounds was diluted with the medium used in the suspension of the each cell, and this was added to each of the wells of the cell culture plates such that the final concentration of DMSO would be 0.2%. The cells were further cultured for three days at 37° C. in an incubator containing 5% carbon dioxide gas. Counting of the number of cells before the addition of the compounds and after the culture for three days in the presence of the compounds, was carried out with a CELLTITER GLO (Promega Corp.) on the basis of the protocol recommended by Promega Corp. The proliferation inhibition ratio was calculated by the following formula, and the concentration of the test compound inhibiting 50% (GI50 (nM)) was determined. [0000] Proliferation inhibition ratio (%)=( C−T )/( C−C 0)×100 [0604] T: Luminescence intensity of a well in which the test compound was added [0605] C: Luminescence intensity of a well in which the test compound was not added [0606] C 0 : Luminescence intensity of a well measured before the addition of the test compound [0607] When a comparison is made between the cell proliferation inhibitory activity against A431 cells that depends on the EGFR proliferation signaling and the cell proliferation inhibitory activity against TMD8 cells that depends on the BTK proliferation signaling, the influence of the respective kinases at a cellular level is able to be evaluated. That is, when the “A431 cell proliferation inhibition ratio/TMD8 cell proliferation inhibition ratio” is calculated, it is contemplated that as the value of the ratio is larger, the selectivity to BTK over EGFR in the cells is higher. The values of “A431 cell proliferation inhibition ratio/TMD8 cell proliferation inhibition ratio” are indicated in Table 20 and Table 21.

These results show that the compounds of the present invention can reduce adverse effects compared with existing BTK inhibitors. Test Example 4 Inhibitory Activity Against B-Cell Activation Using Ramos Cells [0609] The human B-cell lymphoma-derived cell line, Ramos cells were suspended in RPMI1640 medium, and then the cells were inoculated in a culture plate at a concentration of 2.0×10 6 (cells/well). The cells were cultured in a CO 2 incubator (Sanyo Electric Biomedical Co., Ltd.) at 37° C. for 12 hours. Each of Reference compound 1, Example Compound 12, and Example Compound 13 was diluted stepwise with DMSO, the dilution was added to the plate inoculated with cells, and the cells were cultured in a CO 2 incubator for 1 hour. Then, 10 minutes of stimulation was provided with Goat F(ab′)2 anti-human IgM antibody-UNLB (southern biotech Corp.). Thereafter, the cells were harvested, and 50 μL of (a cell extract (NP-40; Invitrogen, Inc.) containing 1×protease inhibitor (Hoffmann-La Roche AG) and 1×phosphatase cocktail inhibitor (Sigma-Aldrich Co.)) was added to the cell pellets. The cell pellets were left to stand for 10 minutes on ice. The amount of protein in the collected cell extract was quantitatively analyzed by a DC protein assay (Bio-Rad Laboratories, Inc.), and 20 μg of proteins per lane was applied to a Criterion TGX™ (Bio-Rad Laboratories, Inc.). After electrophoresis was performed, Western blotting was performed with Trans-Blot™ Turbo™ (Bio-Rad Laboratories, Inc.). Thereafter, phosphorylated BTK protein and BTK protein were detected with LAS4000 (GE Healthcare, Inc.) with a BTK phosphor (pY223) antibody (EPITOMICS Inc.) and a BTK antibody (Abcam, plc.). Then, a ratio of phosphorylated BTK protein to BTK protein was obtained from a luminescence intensity of each of the detected proteins, and the compound concentration at which the phosphorylated BTK protein could be suppressed in 50% was defined as the IC50 value (nM). Table 22 shows the phosphorylated BTK inhibitory concentration (IC50; (nM)). [0610] Table 22 showed that Reference compound 1 exhibited the BTK phosphorylation inhibition at 0.70 (nM), while the compounds of the present invention exhibited equivalent or higher BTK phosphorylation inhibitions, and it was found that the compounds of the present invention inhibit an activation signal of a B-cell through a stimulation of a B-cell receptor. [0611] Rituxan targeted to B-cell is known to exhibit an effect in autoimmune diseases induced by autoantibodies, including rheumatoid arthritis (Non-Patent Literature: Rastetter et al., Annu Rev Med, 55, 2004). [0612] Since it was confirmed from the test that the compounds of the present invention suppress an activation of a B-cell through a stimulation of a B-cell receptor, the compounds of the present invention were considered to exhibit an excellent drug efficacy against autoimmune diseases associated with B cell involved in autoantibody production.

After a culture supernatant was removed and the cells were washed, an anti-DNP-mouse IgE (Alpha Diagnostic Inc.) solution was added thereto, and the cells were cultured in the CO 2 incubator for 1 hour. After a culture supernatant was removed and the cells were washed, an MEM medium was added thereto. Each of Reference Compound 1, Example Compound 1, Example Compound 12, and Example Compound 13 was diluted stepwise with DMSO, the dilution was added to the plate inoculated with cells, and the cells were cultured in the CO 2 incubator for 30 minutes. [0614] Further, a DNP-BSA (LSL, Inc.) solution was added thereto and the cells were cultured in the CO 2 incubator for 15 minutes. A culture supernatant was collected and reacted, with PGD 2 -MOX EIA kit (Cayman Chemical Inc.) on the basis of the protocol attached thereto, and absorbance was measured by SUNRISE RAINBOW THERMO (TECAM Inc.). Amount of PGD 2 in the culture supernatant was calculated on the basis of the measured absorbance, and the compound concentration at which the PGD 2 production amount could be suppressed by 50% compared to the control was defined as the IC50 value (nM). Table 23 shows the concentrations at which the PGD 2 production is inhibited (IC50; (nM)). [0615] Table 23 showed that Reference compound 1 exhibited a PGD 2 production inhibition at about 350 (nM), while the compounds of the present invention exhibited PGD 2 production inhibition property far stronger than that of Reference compound 1. [0616] When IgE antibodies are bound to FCε receptors on mast cells, and those antibodies are cross-linked by an antigen, the mast cells are activated and various chemical mediators (histamine, PGD 2 , or leukotriene) are excreted or secreted. These are known to be significantly associated with incidence of allergic diseases, for example, bronchial asthma and allergic rhinitis (Non-Patent Literature: Ellmeier W., et al., FEBS Journal., 278, 2011). [0617] Since it was confirmed that the compounds of the present invention regulate the excretion or secretion of the chemical mediators of mast cells in the downstream of the FCε receptor, the compounds of the present invention were considered to exhibit an excellent drug efficacy against allergic diseases.

(Initial immunization). After 21 days therefrom, the mice were intracutaneously injected in the base of the tail with 100 μL/body of the equal amount-mixed solution (emulsion) of a 4 mg/mL bovine type 2 collagen solution (Collagen Research Center) and a complete freund's adjuvant (DIFCO Inc.) to carry out an additional immunization. Once-a-day oral administration of Vehicle, Example Compound 12, Example Compound 13, or Reference compound 1 was continued for 21 days including the day in which the additional immunization was carried out (set as day 0). Symptoms of arthritis in day 0, day 4, day 7, day 10, day 14, day 17, and day 21 were scored with the naked eye (0: No change, 1: Swelling of one finger, 2: Swelling of two fingers or more, 3: Swelling of instep, 4: Swelling of all fingers besides swelling extending to wrist/ankle), and a total of four limbs was obtained as a point of an individual (maximum 16 points) to compare the effect in the same model in each of the administration groups. The results are shown in FIG. 1 . [0619] From FIG. 1 , it has been confirmed that the compounds of the present invention completely suppressed increase of the arthritis score after the additional immunization, compared to Reference compound 1, and that the compounds of the present invention have an excellent preventing effect against incidence of rheumatoid arthritis. Incidentally, toxicity causing, for example, a remarkable decrease in body weight or skin disorders including epilation was not observed at the doses of the Example Compounds used in the test. Test Example 7 Mouse Collagen-Induced Arthritis Model (Therapeutic Effect) [0620] The test was carried out in accordance with the method described in Non-Patent Literature (Brand D D, et al., Nat Protoc. 2007; 2, 1269-1275, Xu D. et al., JPET, 2012 April; 341(1): 90-103). Seven-week-old male/DBA/1 mice (CHARLES RIVER LABORATORIES JAPAN, INC.) were intracutaneously injected in the dorsum with 100 μL/body of an equal amount-mixed solution (emulsion) of a 4 mg/mL bovine type 2 collagen solution (Collagen Research Center) and a complete freund's adjuvant (DIFCO Inc.) (Initial immunization). After 21 days therefrom, the mice were intracutaneously injected in the base of the tail with 100 μL/body of the equal amount-mixed solution (emulsion) of a 4 mg/mL of bovine type 2 collagen solution (Collagen Research Center) and a complete freund's adjuvant (DIFCO Inc.) to carry out an additional immunization. Once-a-day oral administration of Vehicle, Example Compound 13, or Reference compound 1 was continued for 15 days, setting the sixth day from the additional immunization as the administration initiation day (day 0). Symptoms of arthritis in day 0, day 4, day 7, day 11, and day 14 were scored with the naked eye (0: No change, 1: Swelling of a finger, 2: Swelling of two fingers or more, 3: Swelling of instep, 4: Swelling of all fingers besides swelling extending to wrist/ankle), and a total of four limbs was obtained as a point of an individual (maximum 16 points). The results are shown in FIG. 2 . [0621] From FIG. 2 , it has been confirmed that the compounds of the present invention decreased the arthritis score while Reference compound 1 delayed the further increase of the increased arthritis score, and that the compounds of the present invention have an excellent therapeutic effect against rheumatoid arthritis which has already established. Incidentally, toxicity causing, for example, a remarkable decrease in body weight or skin disorders including epilation was not recognized at the doses of the Example Compounds used in the test. Test Example 8 Mouse Collagen-Induced Arthritis Model (Therapeutic Effect) [0622] A test similar to Test example 7 was carried out, by using the Vehicle, Example Compound 12, and Reference compound 1. The results are shown in FIG. 3 . [0623] From FIG. 3 , it has been confirmed that the compounds of the present invention remarkably decreased the arthritis score while Reference compound 1 delayed the further increase of the increased arthritis score, and that the compounds of the present invention have an excellent therapeutic effect against rheumatoid arthritis which has been already established. Incidentally, toxicity causing, for example, a remarkable decrease in body weight or skin disorders including epilation was not recognized at the doses of the Example Compounds used in the test. Test Example 9 Mouse Antigen-Induced Dermatitis Model [0624] Type I allergy models accompanied by a skin symptom (a dermatitis model) were produced, with TNP-IgE mice (CLEA Japan, Inc.). The mice are genetically modified BALB/c mice that constantly produce an IgE specific to hapten TNP (trinitrophenol) which is widely used as an allergen (antigen). It is possible to induce an allergic reaction in the mice, only by administering an allergen, without carrying out an immunization. An 0.025% acetone solution of picryl chloride (NACALAI TESQUE, INC.) which is an allergen was applied to ear skin of both ears of the mice at 10 L/ear, and in 2 hours after the application of the antigen, thickenings of the ears were measured by a dial thickness gauge (Ozaki Mfg., PEACOCK G-2M). An average value of thickening values of both ears was obtained as a value of an individual (provided that a previous value before the allergen application was 0 mm). Vehicle, Reference compound 1, Example Compound 1, Example Compound 6, Example Compound 12, or Example Compound 13 was orally administered 30 minutes before the allergen application. [0625] Ear swelling control ratio (%) was calculated by the following formula. The results are shown in Table 24. [0000] Ear swelling control ratio (%)=(1−(Average value of ear thickening of compound administered group)/(Average value of ear thickening of vehicle administered group))×100 [0000] TABLE 24 Example Ear swelling (control No. Dosage (mg/kg) ratio (%) 1 1 66 3 81 12.5 91 6 3 45 12 1 64 3 80 12.5 83 13 1 54 3 79 12.5 77 Reference 12.5 49 compound 1 [0626] From Table 24, it was confirmed that Example Compound 1, Example Compound 6, Example Compound 12, and Example Compound 13 suppressed equivalently or strongly ear swellings induced by the allergen application from low dose of each compound compared with Reference compound 1, and that the compounds of the present invention exhibit an excellent drug efficacy against atopic dermatitis. Test Example 10 Guinea Pig Antigen-Induced Rhinitis Model [0627] A type-I allergy model accompanied by a rhinocleisis (a rhinitis model) was produced, by using a guinea pig (Japan SLC, Inc.). The model is sensitized by subcutaneous administration with 1 mL/body of physiological saline containing 1 mg/mL ovalbumin (OVA solution) by use of a 1 mL syringe with 23 G needle, and the sensitization day was set as day 0. It is possible to induce an allergic reaction by administering each 20 μL of 10 mg/mL OVA solution to both of the nasal cavities on day 7, day 14 and day 21. A single oral administration of vehicle or Example Compound 13 was carried out two hours before the antigen induction of day 21. On day 20, resistance values in nasal cavities of the individuals were measured severally as a pre value of an individual, and on day 21, 15 minutes and 240 minutes after the antigen induction, the resistance values in nasal cavities were measured. [0628] The resistance values in nasal cavities (change ratio; %) was calculated by the following formula. The results are shown in FIG. 4 . [0629] Resistance value in nasal cavity (change ratio; %)=((Resistance values in nasal cavity of vehicle administered group or Example Compound administered group (15 min. or 240 min.; day 21))/(Resistance value in nasal cavity of vehicle administered group or Example Compound administered group (pre; day 20))−1)×100 [0630] Compared with the vehicle administered group that exhibited increases in the resistance in nasal cavities due to the antigen induction, Example Compound 13 suppressed the increase of the resistance in nasal cavities in the early phase and in the late phase in a dose-response fashion, according to FIG. 4 . Thus, it has been confirmed that the compounds of the present invention exhibit an excellent efficacy against allergic rhinitis or pollinosis. Test Example 11 Influence on Body Weight of SD Rat by Repeated Administration with the Compounds of the Present Invention (In Vivo) [0631] The influence on the increase in the body weight of SD rats by repeated administration with Reference compound 1 and the compounds of the present invention for two weeks, was compared with that of a vehicle-administered group. The rats were grouped as follows, with four animals in each group, by a random classification method such that the average body weights of the respective groups would be almost uniform (Day 1). [0632] Group 1: Reference compound 1 (280 mg/kg) was orally administered once a day, Group 2: Example Compound 12 (750 mg/kg) was orally administered once a day, and Group 3: Example Compound 13 (750 mg/kg) was orally administered once a day. [0633] The body weight change (BWC) was used as an index indicating the systemic toxicity caused by the compound administration. The BWC was calculated by the following formula. [0000] BWC (%)=([(Rat body weight on 14 days after the administration)−(Rat body weight at the time of grouping)]/(Rat body weight at the time of grouping))×100 [0634] The relative body weight change ratios in the each compound-administered groups were calculated by the following formula when the BWC in the vehicle-administered group was set as 1, and the results are indicated in Table 25. [0000] Relative body weight change ratio (%)=(BWC in the compound-administered group)/BWC in the vehicle-administered group)×100 [0000] TABLE 25 Relative body weight Dosage (mg/kg) change ratio (%) Group 1 280 30.9 Group 2 750 91.2 Group 3 750 79.1 [0635] According to the results, the width of rat body weight increase was very small in Group 1, which was the Reference compound 1-administered group compared with the vehicle-administered group. Whereas in Groups 2 and 3, which were the groups administered the compounds of the present invention, the increase of the rat body weight was hardly affected. The compounds of the present invention were administered with a 2.5-fold or more the amount of the Reference compound 1 (an approximately 5-fold amount in terms of AUC 0-24 (μM: hr)). Furthermore, in Group 1, individuals suffering from loose bowel were recognized; however, in Groups 2 and 3, no such individuals were recognized. Therefore, the compounds of the present invention have an excellent effect that the level of adverse effects is low despite that the amount of exposure is far larger than that of the Reference compound 1. [0636] As described above, it was made clear that the compounds of the present invention are compounds having superior profiles with reduced toxicity compared with the Reference compound 1. Test Example 12 Mouse Systematic Lupus Erythematosus Model [0637] MRL/lpr mice (Japan SLC, Inc.) were used to evaluate drug efficacy in this test, since the mice are widely used as mice models in which symptoms of autoimmune diseases similar to human systemic lupus erythematosus spontaneously express. A grouping was carried out on the basis of swellings of lymph nodes in submaxilla and axilla at 14 weeks old, and once-daily oral administration was continued for 42 days from the day of grouping, with vehicle or Example Compound 13 suspension. Urea nitrogen concentration and anti-dsDNA antibody concentration in peripheral blood at the final administration day were measured. The results are shown in FIG. 5 . [0638] From FIG. 5 , it has been confirmed that Example Compound 13 suppressed the increased urea nitrogen which was a renal function marker or the increased anti-dsDNA antibody which was an autoantibody compared with the vehicle administered group, and that the compounds of the present invention exhibit an excellent efficacy against a systemic lupus erythematosus which has been already established. Incidentally, a remarkable decrease in body weight was not recognized at the doses of the Example Compound used in the test.
