Description

Technical Field

[0001] The present invention relates to novel regulators of retinoic acid-related orphan receptor γ (RORγ), methods for their preparation, pharmaceutical compositions containing these regulators, and their use in the treatment of RORγ-mediated inflammatory, metabolic, and autoimmune diseases. Background Art

[0002] Retinoic acid receptor-related orphan receptors (RORs) are a class of ligand-dependent transcription factors that play important roles in a series of physiological and pathological processes such as reproductive development, regulation of circadian rhythm, metabolic disorders, inflammation, and immune system regulation. RORs are members of the nuclear receptor superfamily, including RORα, RORβ, and RORγ. RORα is mainly distributed in the liver, skeletal muscle, skin, lung, adipose tissue, kidney, thymus, brain, and blood, and is related to physiological and pathological processes such as hepatic glycogenolysis, lipid metabolism, and atherosclerosis. RORβ is mainly distributed in the central nervous system, including the brain, retina, and pineal gland, and is mainly related to the processing of sensory information by the spinal cord, thalamus, and cerebellar cortex. RORγ is highly expressed in the thymus and is also distributed in the kidney, liver, heart, skeletal muscle, adipose tissue, testis, prostate, and pancreas, and is related to autoimmune diseases such as rheumatoid arthritis, psoriasis, and multiple sclerosis.

[0003] RORγ includes two subtypes, RORγ1 and RORγ2 (RORγt). RORγ1 is expressed in a variety of tissues including the thymus, muscle, kidney, and liver; RORγt is uniquely expressed only in immune system cells and plays a key role in thymopoiesis, the development of several secondary lymphoid tissues, and Th17 lineage differentiation. Studies have shown that RORγt is a key regulator of Th17 cell differentiation. Th17 cells are a subtype of T helper cells that produce IL-17 and other pro-inflammatory cytokines. Th17 cells play a key role in several murine autoimmune disease models, including experimental autoimmune encephalomyelitis (EAE) and collagen-induced arthritis (CIA). In addition, studies have shown that Th17 cells or their products are related to the pathology of various human inflammatory and autoimmune diseases, including multiple sclerosis, rheumatoid arthritis, psoriasis, Crohn's disease, and asthma. The main cause of autoimmune diseases is the intolerance to autoantigens and the development of autoreactive effector T cells that infiltrate tissues. Th17 cells are one of the important driving factors in the inflammatory process of tissue-specific autoimmunity. During the development of the disease, Th17 cells are activated and are responsible for recruiting other inflammatory cells (neutrophils), thereby mediating the lesions of target tissues.

[0004] RORγt has been reported to be a key regulator of Th17 cell differentiation, and Th17 cells have recently been found to be a subset of T helper cells that preferentially produce the cytokines IL-17A, IL-17F, IL-21, and IL-22. RORγt induces the transcription of the genes encoding IL-17A and IL-17F in naive CD4+ T helper cells. Mice deficient in RORγt show very few Th17 cells. Inhibition or deletion of RORγt ameliorates EAE.

[0005] In asthma patients, increased levels of RORγt and IL-17A expression have been shown in saliva, lung, bronchoalveolar lavage (BAL) fluid, and peripheral blood, and the levels are directly correlated with disease severity. In addition to IL-17A, recent studies have shown that another cytokine of the IL-17 family, IL-17F, may have an important role in allergic airway inflammation and thus have an important impact on airway diseases such as asthma. Overexpression of the IL-17F gene in the mouse airway is associated with airway neutrophilia, cytokine induction, increased airway hyperresponsiveness, and mucus hypersecretion.

[0006] In view of the role of RORγ in the pathogenesis of diseases, it is desirable to prepare compounds that modulate the activity of RORγ and are thus useful for treating RORγ-mediated inflammatory, metabolic, and autoimmune diseases such as the respiratory diseases asthma, chronic obstructive pulmonary disease (COPD), and bronchitis, allergic diseases including allergic rhinitis and atopic dermatitis, cystic fibrosis, and lung allograft rejection.
