Description

本発明は、環状アミン誘導体及びその医薬用途に関する。 The present invention relates to cyclic amine derivatives and their pharmaceutical use.

自己免疫疾患は、過剰な免疫反応が自己の正常な細胞や組織を攻撃することで症状を来す疾患の総称であり、例えば、多発性硬化症、乾癬、関節リウマチ、全身性エリテマトーデス、炎症性腸疾患、強直性脊椎炎、ぶどう膜炎又はリウマチ性多発性筋痛症が挙げられる。 Autoimmune disease is a general term for diseases in which excessive immune reactions attack normal cells and tissues of self, and causes symptoms such as multiple sclerosis, psoriasis, rheumatoid arthritis, systemic lupus erythematosus, and inflammatory disease. Intestinal disorders, ankylosing spondylitis, uveitis or polymyalgia rheumatica.

アレルギー性疾患は、免疫反応が特定の抗原に対して過剰に起こることに由来する疾患であり、例えば、アレルギー性皮膚炎、アトピー性皮膚炎、アレルギー性鼻炎(花粉症)、アレルギー性結膜炎、アレルギー性胃腸炎、気管支喘息、小児喘息又は食物アレルギーが挙げられる。 An allergic disease is a disease resulting from an excessive immune reaction to a specific antigen, and examples thereof include allergic dermatitis, atopic dermatitis, allergic rhinitis (hay fever), allergic conjunctivitis, and allergies. Gastroenteritis, bronchial asthma, childhood asthma or food allergies.

自己免疫疾患やアレルギー性疾患の発症及び進展には様々なメカニズムが提唱されているが、その一つとして、ヘルパーT細胞のサブセットの一つであるTh17細胞及びそれが産生する炎症性サイトカインであるIL−17が自己免疫疾患の発症及び進展において重要な役割を果たしていることが知られている(非特許文献1及び2)。 Various mechanisms have been proposed for the onset and progression of autoimmune diseases and allergic diseases, and one of them is Th17 cells, which is one of the subsets of helper T cells, and inflammatory cytokines produced by them. It is known that IL-17 plays an important role in the onset and progression of autoimmune diseases (Non-patent documents 1 and 2).

IL−17は、線維芽細胞、上皮細胞、血管内皮細胞、マクロファージ等の種々の細胞に作用し、炎症性サイトカイン、ケモカイン、メタロプロテアーゼ及びその他の炎症性メディエーターの誘導や好中球の遊走に関わっている。このため、IL−17の産生又は機能を抑制することができれば強い抗炎症作用が発揮されると考えられており、種々の自己免疫疾患を適応症とした抗IL−17抗体の臨床試験が実施されている。 IL-17 acts on various cells such as fibroblasts, epithelial cells, vascular endothelial cells, and macrophages, and is involved in the induction of inflammatory cytokines, chemokines, metalloproteases and other inflammatory mediators and migration of neutrophils. ing. Therefore, it is considered that if the production or function of IL-17 can be suppressed, a strong anti-inflammatory action will be exerted, and clinical studies of anti-IL-17 antibody for various autoimmune diseases are conducted. Has been done.

近年、核内受容体であるレチノイド関連オーファン受容体γ(以下、RORγ)が、Th17細胞の分化増殖及びIL−17の発現に必須な転写因子として機能していることが明らかとなり(非特許文献3)、RORγの発現又は機能を抑制することによって、Th17細胞の分化及び活性化並びにIL−17の産生が抑制されることが示された(非特許文献4)。 In recent years, it has been clarified that the retinoid-related orphan receptor γ (hereinafter referred to as RORγ), which is a nuclear receptor, functions as a transcription factor essential for Th17 cell differentiation/proliferation and IL-17 expression (non-patent document). Reference 3), it was shown that by suppressing the expression or function of RORγ, the differentiation and activation of Th17 cells and the production of IL-17 were suppressed (Non-Patent Document 4).

自己免疫疾患(多発性硬化症、乾癬、全身性エリテマトーデス等)患者やアレルギー性疾患(アレルギー性皮膚炎等)患者では、末梢血単核球又は皮膚組織におけるRORγ発現量が健常人と比較して高い値を示すことが報告されている(非特許文献5〜7)。RORγのノックアウトマウスでは、多発性硬化症の動物モデルであるマウス実験的自己免疫性脳脊髄炎モデルの病態が抑制されることや、大腸炎等の自己免疫疾患の症状や喘息等のアレルギー性疾患の症状が抑制されることが報告されている(非特許文献3、8及び9)。 In patients with autoimmune diseases (multiple sclerosis, psoriasis, systemic lupus erythematosus, etc.) and patients with allergic diseases (allergic dermatitis, etc.), the RORγ expression level in peripheral blood mononuclear cells or skin tissues is higher than that in healthy individuals. It has been reported to show a high value (Non-Patent Documents 5 to 7). In RORγ knockout mice, the pathology of mouse experimental autoimmune encephalomyelitis model, which is an animal model of multiple sclerosis, is suppressed, and symptoms of autoimmune diseases such as colitis and allergic diseases such as asthma It has been reported that the symptom is suppressed (Non-patent documents 3, 8 and 9).

さらに、RORγが転写因子として機能するためには、RORγとコアクチベーターとの結合が必要であることが示唆されている(非特許文献10)。このため、RORγとコアクチベーターとの結合を阻害する化合物であるRORγアンタゴニストは、自己免疫疾患の治療剤又は予防剤として有用であると期待されている。 Furthermore, it has been suggested that RORγ needs to bind to a coactivator in order for RORγ to function as a transcription factor (Non-Patent Document 10). Therefore, a RORγ antagonist, which is a compound that inhibits the binding between RORγ and coactivator, is expected to be useful as a therapeutic or preventive agent for autoimmune diseases.

一方、RORγアンタゴニストとしては、これまでにN−(5−(N−(4−(1,1,1,3,3,3−ヘキサフルオロ−2−ヒドロキシプロパン−2−イル)フェニル)スルファモイル)−4−メチルチアゾール−2−イル)アセトアミド(非特許文献11)や、6−(2−クロロ−4−メチルフェニル)−3−(4−シクロプロピル−5−(3−ネオペンチルシクロブチル)イソオキサゾール−3−イル)−5−オキソヘキサン酸をはじめとする置換アゾール誘導体(特許文献1)や、N−(2−クロロ−2’−(トリフルオロメトキシ)−[1,1’−ビフェニル]−4−イル)−2−(4−(メチルスルホニル)フェニル)アセトアミド等のスルホニルベンゼン誘導体(特許文献2)が報告されているが、1位置換ピペリジン−2−カルボキサミド等の環状アミン構造を有するものは開示されていない。 On the other hand, as RORγ antagonists, N-(5-(N-(4-(1,1,1,3,3,3-hexafluoro-2-hydroxypropan-2-yl)phenyl)sulfamoyl) has hitherto been used. -4-Methylthiazol-2-yl)acetamide (Non-Patent Document 11) and 6-(2-chloro-4-methylphenyl)-3-(4-cyclopropyl-5-(3-neopentylcyclobutyl). Substituted azole derivatives such as isoxazol-3-yl)-5-oxohexanoic acid (Patent Document 1) and N-(2-chloro-2′-(trifluoromethoxy)-[1,1′-biphenyl ] 4-sulfonyl)-2-(4-(methylsulfonyl)phenyl)acetamide and other sulfonylbenzene derivatives (Patent Document 2) have been reported, but a cyclic amine structure such as 1-position substituted piperidine-2-carboxamide has been reported. What has has not been disclosed.

また、1位置換ピペリジン−2−カルボキサミド等の環状アミン構造を有する化合物としては、C型肝炎ウイルス複製阻害剤として、(S)−1−プロピオニル−N−(4’−(2−((S)−1−プロピオニルピロリジン−2−イル)−1H−イミダゾール−4−イル)−[1,1’−ビフェニル]−4−イル)ピロリジン−2−カルボキサミド等(特許文献3)、及び、2−((4−((4−アミノフェニル)チオ)−3−((7−イソプロピルピリド[2,3−d]ピリミジン−4−イル)アミノ)フェニル)カルバモイル)ピロリジン−1−カルボン酸 (S)−ベンジル等が報告されているが(特許文献4)、これらの化合物のRORγに対する作用については開示も示唆もされていない。 Moreover, as a compound having a cyclic amine structure such as 1-position substituted piperidine-2-carboxamide, as a hepatitis C virus replication inhibitor, (S)-1-propionyl-N-(4′-(2-((S )-1-propionylpyrrolidin-2-yl)-1H-imidazol-4-yl)-[1,1′-biphenyl]-4-yl)pyrrolidin-2-carboxamide and the like (Patent Document 3) and 2- ((4-((4-aminophenyl)thio)-3-((7-isopropylpyrido[2,3-d]pyrimidin-4-yl)amino)phenyl)carbamoyl)pyrrolidine-1-carboxylic acid (S )-Benzyl and the like have been reported (Patent Document 4), but neither the action nor the action of these compounds on RORγ is disclosed or suggested.

しかしながら、自己免疫疾患やアレルギー性疾患の実際の治療には、免疫系全体に対して作用するステロイド剤又は免疫抑制剤が内服薬として用いられており、感染症等の重篤な副作用の懸念から十分な薬効が認められる前に投与を中止せざるを得ないケースが臨床的に多数存在しているのが現状である。このため、自己免疫疾患やアレルギー性疾患の発症及び進展メカニズムにおいて重要な役割を果たしている分子を標的とした新たな医薬の開発が切望されている。 However, for the actual treatment of autoimmune diseases and allergic diseases, steroids or immunosuppressive agents that act on the entire immune system are used as internal medicines, which is sufficient from the fear of serious side effects such as infectious diseases. The current situation is that there are many clinical cases in which the drug must be discontinued before its efficacy is recognized. Therefore, there is a strong demand for the development of a new drug targeting a molecule that plays an important role in the mechanism of onset and progress of autoimmune diseases and allergic diseases.

そこで本発明は、RORγアンタゴニスト活性を有し、多発性硬化症若しくは乾癬等の自己免疫疾患又は接触性皮膚炎若しくはアトピー性皮膚炎等のアレルギー性皮膚炎等のアレルギー性疾患に対して治療効果又は予防効果を発揮する新規な化合物を提供することを目的とする。 Therefore, the present invention has a RORγ antagonist activity and has a therapeutic effect on an autoimmune disease such as multiple sclerosis or psoriasis or an allergic disease such as allergic dermatitis such as contact dermatitis or atopic dermatitis or the like.
