Description

イミダゾール誘導体及びそれを含有する医薬Imidazole derivative and medicament containing the same
 本発明はレチノイン酸受容体関連オーファン受容体γt (retinoic acidreceptor-related orphan receptor-γt:RORγt)阻害作用を有する新規なイミダゾール誘導体又はその塩、及び該イミダゾール誘導体又はその塩を有効成分として含有する医薬に関する。 The present invention comprises a novel imidazole derivative having an inhibitory action on retinoic acid receptor-related orphan receptor γt (retinoic acid receptor-related orphan receptor-γt: RORγt) or a salt thereof, and the imidazole derivative or a salt thereof as an active ingredient It relates to medicine.
 レチノイン酸受容体関連オーファン受容体(retinoic acid receptor-related orphan receptor:ROR)は、オーファン核内受容体サブファミリーの1つであり、RORα、RORβ及びRORγの3つのサブタイプが存在する。RORγtはRORγのアイソフォームであり、主に免疫系の細胞に発現する。近年、RORγtはTh17細胞分化の重要な制御因子として機能していることが明らかとなった(非特許文献1)。Th17細胞の分化におけるRORγtの重要性とTh17細胞の疾患への関与については、RORγtノックアウトマウスのT細胞においてTh17細胞への分化とIL-17産生が抑制されること、多発性硬化症の病態モデルであるExperimental Autoimmune encephalomyelitisの病態が抑制されることにより示されている(非特許文献2)。 The retinoic acid receptor-related orphan receptor (ROR) is one of the orphan nuclear receptor subfamily, and there are three subtypes of RORα, RORβ and RORγ. RORγt is an isoform of RORγ and is mainly expressed in cells of the immune system. In recent years, it has been revealed that RORγt functions as an important regulator of Th17 cell differentiation (Non-patent Document 1). Regarding the importance of RORγt in differentiation of Th17 cells and involvement in disease of Th17 cells, suppression of differentiation to Th17 cells and IL-17 production in T cells of RORγt knockout mice, pathogenesis model of multiple sclerosis It is shown by the suppression of the pathological condition of Experimental Autoimmune encephalomyelitis (Non-patent Document 2).
 Th17細胞は、IL-17A、IL-17F、IL-21及びIL-22などの炎症性サイトカインを産生する、ヘルパーT細胞サブセットの1つである。Th17細胞あるいはIL-17AやIL-17Fなどの炎症性サイトカインは、乾癬、多発性硬化症、炎症性腸疾患(クローン病及び潰瘍性大腸炎等)、関節リウマチ、全身性エリテマトーデスをはじめとする各種自己免疫疾患やアレルギー性疾患においてその関連性が示されている(非特許文献3)。したがって、RORγtの作用を阻害する薬剤は、Th17細胞の分化ならびに活性化を抑制し、Th17細胞あるいはIL-17AやIL-17Fなどの炎症性サイトカインが関与する各種疾患において治療又は予防効果を発揮することが期待される。 Th17 cells are one of the helper T cell subsets that produce inflammatory cytokines such as IL-17A, IL-17F, IL-21 and IL-22. Inflammatory cytokines such as Th17 cells or IL-17A and IL-17F include various species including psoriasis, multiple sclerosis, inflammatory bowel disease (such as Crohn's disease and ulcerative colitis), rheumatoid arthritis, systemic lupus erythematosus, etc. Its relevance has been shown in autoimmune diseases and allergic diseases (Non-patent Document 3). Therefore, drugs that inhibit the action of RORγt inhibit differentiation and activation of Th17 cells, and exert therapeutic or prophylactic effects in various diseases involving inflammatory cytokines such as Th17 cells or IL-17A or IL-17F. It is expected.
