No. 14/394,373, filed on Oct. 14, 2014, which was a 371 of International Patent Application No. PCT/JP2013/061348, filed on Apr. 17, 2013, and claims priority to Japanese Patent Application No. 2012-094278, filed on Apr. 17, 2012, and Japanese Patent Application No. 2013-051487, filed on Mar. 14, 2013.


TECHNICAL FIELD
The present invention relates to a pharmaceutical composition, for example, a nitrogen-containing bicyclic aromatic heterocyclic compound useful as an active ingredient of a pharmaceutical composition for preventing and/or treating autoimmune disease, allergic disease, graft rejection of an organ, bone marrow or tissue, or systemic lupus erythematosus (SLE).
BACKGROUND ART
Cathepsin S is mainly a lysosomal cysteine protease that is expressed on antigen-presenting cells such as dendritic cells, macrophages, and B-cells, and plays a role in the degradation of an invariant chain bonded when major histocompatibility gene complex class II (MHC class II) molecules are generated. MHC class II molecules are bonded to self-peptide or non-self peptide taken from the outside of a cell, and by presenting the non-self peptide or pathogenic self-peptide to CD4 positive T cells, secretion of various cytokines is induced. It is confirmed that by inhibiting cathepsin S or making cathepsin S deficient, loading of antigenic peptide to MHC class II molecules are inhibited, and antigen presentation to CD4 positive T cells is suppressed, and by these, an immune response with respect to a foreign antigen is decreased (Nakagawa et al, Immunity, 1999, Vol. 10, No. 2, pp. 207-217).
In this respect, an inhibitor of cathepsin S can be useful as an agent for preventing and/or treating inflammation and immune disease such as rheumatoid arthritis, multiple sclerosis, SLE, psoriasis and Crohn's disease, and as an agent for preventing and/or treating graft rejection.
It have been reported that the compounds represented by the following formulas (A) (Patent Documents 1 and 2), (B) (Patent Document 3), (C) (Patent Document 4), and (D) (Patent Document 5) exhibit cathepsin S inhibition, and are useful as an agent for treating inflammations such as rheumatismimmune disorders and the like. It have been reported that the compound represented by the following formula (E) exhibits cathepsin S inhibition, and is useful as an agent for treating inflammations such as rheumatismimmune disorders and the like (Patent Document 6).

Next, 10-fold dilution of the test compound (a 10 mM DMSO solution) was serially performed with a buffer solution for assay (a solution of 50 mM sodium methoxide, 250 mM sodium chloride and 5 mM dithiothreitol (DTT), adjusted to pH=4.5 with 1 N hydrochloric acid) six times such that the final concentration becomes 0.1 nM to 10 μM, then, 20 μL of each of the solutions was added to the wells (the final DMSO concentration was 0.1%), and 25 μL of synthetic substrate VVR-AMC (3211-V manufactured by PEPTIDE INSTITUTE, INC.) was added thereto such that the final concentration becomes 40 μM, thereby starting a enzyme reaction. A fluorescence intensity (an excitation wavelength: 380 nm and a fluorescent wavelength: 460 nm) was measured at 37° C. for 10 minutes immediately after the start of the reaction using a fluorescence spectrophotometer (SPECTRA MAX GEMINI, manufactured by Molecular Devices Corporation), and the reaction rate at the time (5 minutes or 10 minutes) when linearity was observed was determined at each concentration of the test compound.

Test Example 2
Evaluation of In Vitro MHC Class II Expression Inhibitory Effect Using Mouse Spleen Cells (Cell Evaluation System)
In antigen-presenting cells, the inhibition of cathepsin S inhibits the expression of MHC class II molecules. As a result, antibody production is inhibited, and decrease in an immune response occurs. For an increased expression of MHC class II in B cells, the inhibitory effect of the compound represented by formula (I) was examined.
First, spleen cells collected from C57BL/6 mice were seeded in a 96-well plate so as to be a 1×105 cells/well, then, 5-fold dilution of 10 mM DMSO solution of the test compound was serially performed with RPMI 1640 medium (including 10% fetal bovine serum (FCS), 5×10−5 M 2-mercaptoethanol, 50 IU/mL penicillin and 50 μg/mL streptomycin) nine times such that the final concentration becomes 0.026 nM to 10 μM, and the resultant products were added thereto (the final DMSO concentration was 0.1%). At the same time, LPS (Sigma L4005) was added to the wells such that the final concentration becomes 2 μg/mL, and culture was performed at 37° C. for 48 hours in 5% CO2. After culturing, the cells were stained at 4° C. for 20 minutes with PE-labeled streptavidin (BD BIOSCIENCE 554061) and biotin-labeled YAe antibody (EBIOSCIENCE 13-5741-85) together with FITC-labeled anti-mouse B220 antibody (BD BIOSCIENCE 553088), and an expression level (fluorescence intensity of YAe-biotin/streptavidin-PE) of MHC class II to which Ea peptide in B220 positive B cells was bonded was measured using a flow cytometry system (Guava EasyCyte Plus System, manufactured by Millipore Corporation). A value at the time of unstimulation of LPS in which the test compound was not added and a value at the time of stimulation of LPS in which the test compound was not added were set to 100% inhibition and 0% inhibition, respectively, then, an inhibition rate at each concentration was determined, and IC50 values were calculated by a linear regression method. The results are shown in Table 2. In the Table, Ex represents Example compound No., and Data 2 represents an IC50 value (nM).

Test Example 3
Evaluation of Ex Vivo MHC Class II Expression Inhibitory Effect Using Mouse Peripheral Blood
The expression inhibitory effect of MHC class II molecules was evaluated in an ex vivo system.
The test compound was orally administered into C57BL/6mice, and the inhibitory effect with respect to the increased expression of MHC class II in B cells in peripheral blood after oral administration was examined. That is, 10 mL/kg of the test compound dissolved in a vehicle (30% propylene glycol solvent (propylene glycol:cured castor oil (HCO40):Tween 80=4:2:1)/HCl (2 equivalents with respect to the test compound)/water) was orally administered (dose: 0.1 mg/kg, 0.3 mg/kg, 1 mg/kg, or 3 mg/kg) to a C57BL/6mice, and the peripheral blood was collected after 3 hours. 10 μL of RPMI 1640 medium (including 5×10−5 M of 2-mercaptoethanol, 50 IU/mL of penicillin, and 50 μg/mL of streptomycin) or 10 μL of LPS adjusted with the medium such that the final concentration becomes 100 μg/mL was added to 90 μL of the peripheral blood, and culture was performed at 37° C. for 15 hours in 5% CO2. After culturing, the cells were stained at 4° C. for 30 minutes with FITC-labeled anti-mouse I-A/I-E antibody (BD BIOSCIENCE 553623) and PE-labeled B220 antibody (BD BIOSCIENCE 553090), and hemolysis and fixation were performed at 37° C. for 10 minutes using a buffer (BD BIOSCIENCE Phosflow Lyse/Fix Buffer 558049). After washing, using a flow cytometry system (FACSCanto II, manufactured by BD BIOSCIENCE), an expression level of MHC class II on a B220 positive B cell surface was measured by using a fluorescence intensity of FITC (hereinafter, referred to as MFI) as an indicator. The difference between a MFI at the time of stimulation of LPS and a MFI at the time of unstimulation of LPS was set to a ΔMFI, a ΔMFI of a mouse in which 10 mL/kg of only vehicle was administered was set to 1, and the inhibition rate of ΔMFI by the test compound administration was calculated.
From the results of the above Test 3, the compound of Example 28 exhibited 40±1.4% inhibition (0.3 mg/kg, p<0.001), the compound of Example 39 exhibited 61±1.2% inhibition (1 mg/kg, p<0.001), and the compound of Example 158 exhibited 59±1.5% inhibition (0.3 mg/kg, p<0.001), and thus, the increased expression of MHC class II was significantly inhibited. That is, it was confirmed that some compounds of the formula (I) inhibit the increased expression of MHC class II in peripheral blood B cells.
Test Example 4
Evaluation of Antibody Production Inhibitory Effect in Mouse OVA-Induced Antibody Production Model
Evaluation of an antibody production inhibitory effect in vivo was performed.
The BALB/c male mice were sensitized by intraperitoneal administration of 200 μL of an emulsion consisting of 100 μg of ovalbumin (OVA) (SIGMA A5503) and 100 μL of a complete Freund's adjuvant (CFA) (DIFCO 231131) (Day 0), and a week after that, the mice were sensitized by intraperitoneal administration of 200 μL of an emulsion consisting of 50 μg of OVA and 100 μL of an incomplete Freund's adjuvant (IFA) (DIFCO 263910) (Day 7). The test compound dissolved in a vehicle (30% propylene glycol solvent (propylene glycol:HCO40:Tween 80=4:2:1)/HCl (2 equivalents with respect to the test compound)/water) was orally administered (dose: 0.3 mg/kg, 1 mg/kg, or 3 mg/kg) at 10 mL/kg/day from Day 0 to Day 14, and an OVA specific IgG antibody titer in blood plasma at Day 14 was evaluated. Measurement of antibody titer was carried out using a blood plasma sample which was diluted 40,000 times by an ELISA method, and the antibody titer was represented as a ratio with respect to control blood plasma. An antibody titer of a mouse to which the vehicle was orally administered at 10 mL/kg/day from Day 0 to Day 14 was set to 0% inhibition, an antibody titer of a normal mouse to which the vehicle was orally administered at 10 mL/kg/day from Day 0 to Day 14 and which was not sensitized with OVA was set to 100% inhibition, and the inhibition rate at the time of the test compound administration was calculated.
From the results of the above Test 4, the compound of Example 2 exhibited 61±10% inhibition (1 mg/kg, p=0.02), the compound of Example 28 exhibited 83±2% inhibition (1 mg/kg, p<0.001), and the compound of Example 39 exhibited 74±8% inhibition (0.3 mg/kg, p<0.001), and thus, the antibody production was significantly inhibited. That is, it was confirmed that some compounds of the formula (I) inhibit the antibody production.
Test Example 5
Evaluation of SLE Onset Inhibitory Effect in Spontaneous Model Using NZB/W F1 Mouse
NZB/W F1 mice are used as a model of SLE that spontaneously develops a condition close to humans (Helyer et al, Proceedings of the university otago medical school (New Zealand), 1961, Vol. 39, p. 3; Advances in Immunology, 1985, Vol. 37, p. 269-390; Perry et al, Journal of Biomedicine and Biotechnology, 2011, Article ID 271694, Review Article).
NZB/W F1 female mice were grouped on the basis of a urine protein level at the time of 20 weeks old, an anti-dsDNA antibody titer (IgG, IgM), an expression level of MHC class II in peripheral blood B cells, and a body weight. At this time, an individual having greater than 100 mg/dL of urine protein was excluded. After 20 weeks old, the test compound was orally administered once a day, urine collection and blood collection were performed every 4 weeks thereafter, and time-dependent transitions of urine protein, an anti-dsDNA antibody titer, and an expression level of MHC class II in peripheral blood B cells were evaluated. The evaluation ended at the time when urine protein-increased individual in the vehicle administration group reached the majority (at the time of 41 weeks old).
From the results of the above Test 5, at the time of 41 weeks old, urine protein of individuals of 6 cases among 8 cases in the vehicle administration group was 1,000 mg/dL or more. In the compound administration group (dose: 0.3 mg/kg) of Example 39, urine protein of all individuals of 10 cases was 100 mg/dL or less. Therefore, it was confirmed that the compound of Example 39 included in the formula (I) inhibits an increase of urine protein, and maintains kidney functions.
In addition, in the above Test 5, an anti-dsDNA IgG antibody titer at the time of 41 weeks old was measured by the ELISA method. The average of an anti-dsDNA IgG antibody titer of the vehicle administration group 6 cases was 69,375±20,607 (mU/mL). In the compound administration group (dose: 0.3 mg/kg) of Example 39, the average of an anti-dsDNA IgG antibody titer of 10 cases was 9,263±1,700 (mU/mL). Therefore, it was confirmed that the compound of Example 39 included in the formula (I) inhibits an increase of an anti-dsDNA antibody titer.
Furthermore, a pathology evaluation of kidney tissue in the above Test 5 was performed. A formalin-fixed paraffin-embedded section of kidney tissue was prepared, then, a specimen was prepared by periodic acid-methenamine-silver (PAM) staining, and the specimen was observed with a microscope. In accordance with histological classification of lupus nephritis by WHO, a histopathological image was classified into Class I (normal glomerulus), Class II (mesangium lesion), Class III (focal segmental glomerulonephritis), Class IV (diffuse glomerulonephritis), and Class VI (progressive sclerosing lupus nephritis).
From the results of the above Test 5, it was confirmed that the compound of Example 39 included in the formula (I) can be used for preventing and/or treating SLE.
From the above results, the compound of the formula (I) or salts thereof can be used for preventing and/or treating autoimmune disease, allergic disease, graft rejection of an organ, bone marrow or tissue, SLE, or lupus nephritis.
As an aspect of the graft rejection of an organ, bone marrow or tissue, antibody-related type rejection in which B cells are involved and T cell-related type rejection in which T cells are involved can be exemplified. As another aspect, antibody-related type rejection in which B cells are involved can be exemplified. As an aspect of the autoimmune disease, rheumatoid arthritis, psoriasis, ulcerative colitis, Crohn's disease, systemic lupus erythematosus, Sjogren's syndrome, multiple sclerosis, and the like can be exemplified. As an aspect of the allergic disease, asthma, atopic dermatitis, and the like can be exemplified. As an aspect of SLE, lupus nephritis, central nervous system lupus, and the like can be exemplified.
