The present invention relates to triazole compounds and medicinal use thereof. The present invention relates to isoxazole compounds and medicinal use thereof.
In particular, the present invention relates to compounds which can inhibit retinoid-related orphan receptor gamma (RORγ), thereby the differentiation and activation of T helper 17 (Th17) cells can be inhibited, and the production of interleukin-17 (IL-17) can be inhibited.
Specifically, the present invention relates to compounds for preventing or treating a disease related to Th17 cells, for example, autoimmune disease such as rheumatoid arthritis, psoriasis, inflammatory bowel disease such as Crohn's disease and ulcerative colitis, multiple sclerosis, systemic lupus erythematosus (SLE), ankylosing spondylitis, uveitis, polymyalgia rheumatica, and type I diabetes; allergic disease such as asthma; dry eye; fibrosis such as pulmonary fibrosis and primary biliary cirrhosis; and metabolic disease such as diabetes and medicinal use thereof.
RORγ is a nuclear receptor which is important for the differentiation and activation of Th17 cells. RORγt is also known as a splice variant of RORγ. RORγ and RORγt differ only in their N-terminal domains, and share the same ligand-binding domain and DNA-binding domain. It is reported that RORγ is expressed in other tissues besides Th17 cells. By inhibiting RORγ, the differentiation and activation of Th17 cells can be inhibited. IL-17 produced in Th17 cells is involved in the induction of a variety of chemokines, cytokines, metalloproteases and other inflammatory mediators, and the migration of neutrophil, hence, the inhibition of IL-17 may lead to the inhibition of such induction and migration. RORγ in adipose tissues is related to the regulation of adipogenesis, and by inhibiting RORγ, insulin resistance can be improved.
It is known that Th17 cells are involved in autoimmune disease such as rheumatoid arthritis, psoriasis, inflammatory bowel disease such as Crohn's disease and ulcerative colitis, multiple sclerosis, systemic lupus erythematosus, ankylosing spondylitis, uveitis, polymyalgia rheumatica, and type I diabetes; allergic disease; dry eye; and fibrosis such as pulmonary fibrosis and primary biliary cirrhosis.
As for rheumatoid arthritis, for example, it is reported that the administration of anti-IL-17 antibody can improve swelling and joint destruction associated with collagen-induced arthritis. Moreover, it is reported that swelling and joint destruction associated with collagen-induced arthritis can be improved in IL-17-deficient mice.
As for psoriasis, it is reported that in a clinical trial, the administration of anti-IL-17 antibody is effective in treating psoriasis.
As for inflammatory bowel disease such as Crohn's disease and ulcerative colitis, in a colitis model induced by the adaptive transfer of naive T-cells, the adaptive transfer of naive T-cells derived from RORγ-KO mice does not increase IL-17 in the mucosa, thereby the onset of colitis can be suppressed.
As for multiple sclerosis, the disease state of mouse experimental autoimmune encephalomyelitis model which is an animal model of multiple sclerosis can be suppressed in RORγt-KO mice.
As for systemic lupus erythematosus, it is reported that the onset of GBM nephritis model which is an animal model of glomerulonephritis can be inhibited in RORγt-KO mice. Nephritis associated with SLE may also be suppressed.
As for ankylosing spondylitis, it is reported that the administration of anti-IL-17 antibody is effective in treating ankylosing spondylitis.
As for uveitis, it is reported that the administration of anti-IL-17 antibody is effective in treating uveitis associated with Behcet's disease, sarcoidosis and Harada disease.
As for polymyalgia rheumatica, an efficacy of anti-IL-antibody in treatment of polymyalgia rheumatica is currently tested in a clinical trial.
As for type I diabetes, the disease state of NOD mice which is a type I diabetes model can be suppressed by the administration of anti-IL-17 antibody.
As for allergic disease such as asthma; in OVA-sensitized model, the attenuated eosinophilic pulmonary inflammation, the reduced numbers of CD4+ lymphocytes, and the decrease of Th2 cytokines/chemokines level are exhibited in RORγ-KO mice, that is, the allergenic reaction can be inhibited in RORγ-KO mice.
As for dry eye, it is reported that the Th17 cells increases in an animal model of dry eye, and an efficacy of anti-IL-17 antibody in dry eye patient is currently tested in a clinical trial.
As for fibrosis, in a bleomycin-induced pulmonary fibrosis model which is an animal model of pulmonary fibrosis, the administration of anti-IL-17 antibody can inhibit inflammation and fibrosis in lung and can increase survival of the animal.
As for primary biliary cirrhosis, it is reported that Th17 cells in the lesion area of a patient with a primary biliary cirrhosis increase, and an efficacy of an antibody to IL-23 which activates Th17 cells is currently tested in a clinical trial.
As for metabolic disease, the insulin resistance which is induced by feeding a high-fat diet can be suppressed in RORγ KO mice.
On the basis of these findings, RORγ antagonists are thought to be useful for preventing or treating autoimmune disease such as rheumatoid arthritis, psoriasis, inflammatory bowel disease such as Crohn's disease and ulcerative colitis, multiple sclerosis, systemic lupus erythematosus, ankylosing spondylitis, uveitis, polymyalgia rheumatica, and type I diabetes; allergic disease such as asthma; dry eye; fibrosis such as pulmonary fibrosis and primary biliary cirrhosis; and metabolic disease such as diabetes.
An object of the present invention is to provide novel RORγ antagonists. Another object of the present invention is to provide medicaments of preventing or treating autoimmune disease such as rheumatoid arthritis, psoriasis, inflammatory bowel disease such as Crohn's disease and ulcerative colitis, multiple sclerosis, systemic lupus erythematosus, ankylosing spondylitis, uveitis, polymyalgia rheumatica, and type I diabetes; allergic disease such as asthma; dry eye; fibrosis such as pulmonary fibrosis and primary biliary cirrhosis; and metabolic disease such as diabetes.

Such salts can be formed by reacting compounds of Formula [I] and the like with inorganic base, organic base, inorganic acid, organic acid, or amino acid by conventional methods.
The term “solvate” refers to the compounds of Formula [I] and the like or pharmaceutically acceptable salts thereof which coordinate to the solvent molecules, and also includes hydrates. Such solvates are preferably pharmaceutically acceptable solvates. Such solvate includes for example hydrate, ethanol solvate, dimethyl sulfoxide solvate and the like of compounds of Formula [I] and the like or pharmaceutically acceptable salts thereof.

Such solvates can be produced by conventional methods.
In addition, the compounds of Formula [I] and the like may have a variety of “isomer”. For example, the compounds can exist in E or Z forms or cis or trans isomers as geometric isomers. Moreover, the compounds which have asymmetric carbon atom(s) include enantiomers and diastereomers as stereoisomers according to said asymmetric carbon atom(s). Besides, the compounds which have axial chirality include stereoisomers according to said axial chirality. In some cases, tautomer may be included. Therefore, the present invention includes all of these isomers and mixtures thereof.

When a general formula, a chemical structure, or a compound name is described herein without indicating stereochemistry, the compound includes the above possible isomers, unless otherwise designated.
A diastereomer mixture can be separated into each diastereomer by a conventional method such as chromatography and crystallization. Alternatively, a single diastereomer can be produced by using a stereochemically-single starting material or by synthesis process using a stereoselective reaction.
An enantiomer mixture can be separated into each enantiomer by using a method well-known in the art.
For example, an enantiomer mixture is reacted with a compound which is a substantially pure enantiomer (known as a chiral auxiliary) to give a diastereomer mixture, and then by using a standard technique such as fractionated crystallization or chromatography the diastereomer mixture can be separated into a single diastereomer which has a high isomeric ratio (i.e. substantially pure). The resulting single diastereomer is cleaved to remove the added chiral auxiliary to give an enantiomer of interest.
An enantiomer mixture of a compound can be directly separated by using a chromatography using a chiral stationary phase which is well-known in the art.
Further, either enantiomer of a compound can be obtained by using a substantially pure optically-active starting material, or by stereoselective synthesis (asymmetric induction) wherein a prochiral intermediate is treated with a chiral auxiliary or an asymmetric catalysis.
An absolute configuration can be determined by X-ray crystallographic analysis of a crystalline or an intermediate. The crystalline or the intermediate may be derivatized with a reagent having an asymmetric center whose configuration is known.

Pharmacological effects of the typical compounds of the present invention were observed.
In vitro assay of inhibitory effect against RORγ transcriptional activity
Inhibitory effect of test article on transcriptional activity of RORγ was measured by means of the following luciferase reporter gene assay.
A cDNA encoding human and mouse RORγ ligand binding domain (LBD) were obtained based on the reported sequences (Genebank accession number and sequence: human, NM_005060.3 and from Ser253 to Lys518; mouse, NM_011281.2 and from Ile251 to Lys516).
The cDNA of human RORγ or mouse RORγ was inserted into pFA-CMV vector (Strategene), which expresses GAL4-DNA binding domain fusion protein.
The resulting plasmids are hereinafter referred to as GAL4-hRORγ plasmid and GAL4-mRORγ plasmid, respectively.
Human or mouse GAL4-RORγ plasmid was transiently co-transfected into Chinese hamster ovary cells (CHO cells) with pGL5-Luc plasmid, a reporter plasmid expressing firefly luciferase depending on GAL4.
TransIT CHO transfection reagent (Mirus) was used to co-transfect human or mouse GAL4-RORγ plasmid into CHO cells with pG5-Luc plasmid.
One day before the assay, CHO cells were suspended in HAM F-12 Nutrient medium containing 10 v/v % fetal bovine serum and seeded at 6×106 cells per 175 cm2 cell culture flask.
Fifty four micro litters of Transit-CHO reagent was added into a 15 ml tube containing 1.16 ml of HAM F-12 Nutrient medium without fetal bovine serum and incubated at room temperature for 10 min.
A total 36 uL plasmid solution containing the GAL4-hRORγ plasmid (400 ng), pG5-Luc plasmid (9000 ng) and pcDNA3 plasmid (8600 ng) were added into the tube and mixed gently.
In case of mouse assay, the GAL4-mRORγ plasmid (250 ng), pG5-Luc plasmid (9000 ng) and pcDNA3 plasmid (8750 ng) were added.
The mixture was incubated at room temperature for 10 min.
Nine micro litters of CHO Mojo Reagent was then added into each tube and mixed gently. The mixture was incubated at room temperature for 10 min.
The resultant transfection reagent was applied to the cell culture.
After incubation at 37° C., 5% CO2 for 4 hr, the transfected CHO cells were harvested by a trypsin treatment.
The collected cells were resuspended in HAM F-12 Nutrient medium supplemented with 10 v/v % fetal bovine serum and plated into a 384-well-white plate at 8,000 cells/50 uL/well.
The plate was incubated at room temperature for 1 hour and then further incubated at 37° C., 5% CO2 for 3 hours.
The test articles were dissolved in dimethylsulfoxide (DMSO) to obtain a concentration of 10 mmol/L. The resulting solution was diluted with the medium just before use and added to the cells in the plate to prepare 8 different concentrations of the test article.
The final concentration of DMSO was 0.1 v/v % After the addition of the test articles, the cells were incubated at 37° C., 5% CO2 for 2 days.
Cell viability was tested by a fluorescence method using Resazurin (invitrogen).
Two days after the addition of the test article, Resazurin was diluted with culture medium to make the 20 umol/L resazurin solution.
10 uL of the diluted resazurin solution was added into the 384-well-plate.
Then, the fluorescence was measured immediately at 615 nm with the excitation wavelength of 570 nm (0 hr reading). After incubation at 37° C., 5% CO2 for 2 hr, the fluorescence was measured at 615 nm with the excitation wavelength of 570 nm again (2 hr reading).
The fluorescence counts (2 hr-0 hr) were calculated by subtracting the 0 hr readings from the 2 hr readings.
The luminescence count in the cells treated with 0.1% DMSO alone was defined as 100%, and the cell viability in the test article was calculated as a percentage (%-of-control) based on the value of 0.1% DMSO alone.
When the cell viability is 70% or less, it was judged that the test article has cytotoxicity.
RORγ transcriptional activity was detected as the intracellular luciferase activity using SteadyLite HTS Reporter Gene Assay System (Perkin Elmer).
StedyLite Reagent was diluted five-fold into a solution containing 10 mM Tricine, 0.2% w/v BSA, 0.02% v/v Tween-20 to obtain the luciferase substrate solution.
After the measurement of the cell viability using Resazurin, the culture media in the 384 well-plate were removed. Then the Luc substrate solution was added into each well.
After the incubation at room temperature for 10 minutes, luminescence of each well was measured by a microplate reader.
The luciferase activity derived from the luminescence count in the vehicle-control well treated with 0.1% DMSO alone was defined as 100%, and the luciferase activity in the test article was calculated as a percentage (%-of-control) based on the value of the vehicle-control.
EC50 value of test article was calculated by curve fitting with GraphPad Prism.
The luminescence counts at the concentration of the test article where the cytotoxicity was observed were excluded from the data analysis.
The results are shown in Tables 360-385.
In the tables, “+” means EC50≧3 μM, and “++” means EC50<3 μM.
