Description

複素環化合物Heterocyclic compounds
 本発明は、プロテインキナーゼC(本明細書中「PKC」と略記する場合がある)阻害作用を有し、免疫性疾患、炎症性疾患等の治療に有用な複素環化合物、それらを含有する医薬組成物などに関する。 The present invention relates to a heterocyclic compound having an inhibitory action on protein kinase C (sometimes abbreviated as “PKC” in the present specification) and useful for the treatment of immune diseases, inflammatory diseases, and the like, and a medicament containing them It relates to compositions and the like.
(発明の背景)
 免疫システムにおいて、T細胞は、ウイルスや細菌などの外来抗原や癌を排除する獲得免疫機構の一部として重要な役割を果たしている。一方、過剰なT細胞の活性化は、自己免疫疾患の発症に関与することや、移植にともなう拒絶などの人体に対して有害な反応を引き起こすことが知られていることから、T細胞は、これらの疾患において有望な治療ターゲットであると考えられている(非特許文献1)。このことは、腎移植、肝移植、心移植、肺移植、膵移植、小腸移植などの臓器移植における拒絶反応、骨髄移植における拒絶反応、移植片対宿主病、ベーチェット病、尋常性乾癬、膿疱性乾癬、乾癬性紅皮症、関節症性乾癬、再生不良性貧血、赤芽球癆、ネフローゼ症候群、全身型重症筋無力症、アトピー性皮膚炎、潰瘍性大腸炎等の疾患において、T細胞の活性化を抑制する薬剤であるカルシニューリン阻害薬(TacrolimusおよびCyclosporin A)が、予防薬もしくは治療薬として日本において承認されていることからも明白である(非特許文献2および3)。
 PKCファミリーは少なくとも12種類のサブタイプからなり、様々な組織で発現することが知られている。また、PKCファミリーはT細胞、B細胞やマクロファージなどの免疫担当細胞で発現し、種々の免疫反応に重要な役割を果たしていることから、免疫疾患や炎症性疾患に関与すると考えられている(非特許文献4)。
 その中で、PKC-θは、T細胞に選択的に発現するリン酸化酵素であり、T細胞受容体に対する刺激の細胞内への伝達を担い、T細胞の活性化に重要な役割を果たしている。
 PKC-θの阻害は、T細胞の活性化を抑制することが知られており(非特許文献5)、またPKC-θ欠損マウスは、多発性硬化症モデル、炎症性腸疾患モデル、移植片体宿主病モデル、慢性関節リウマチモデルおよび喘息モデルにおいて抵抗性であることが報告されている(非特許文献6~8)。
 以上のことから、PKC(例、PKC-θ)阻害薬は、腎移植、肝移植、心移植、肺移植、膵移植、小腸移植などの臓器移植における拒絶反応、骨髄移植における拒絶反応、移植片対宿主病、ベーチェット病、尋常性乾癬、膿疱性乾癬、乾癬性紅皮症、関節症性乾癬、再生不良性貧血、赤芽球癆、ネフローゼ症候群、全身型重症筋無力症、アトピー性皮膚炎、潰瘍性大腸炎、喘息等の様々な免疫性疾患および炎症性疾患において予防薬もしくは治療薬になる。
(Background of the Invention)
In the immune system, T cells play an important role as part of an acquired immune mechanism that eliminates foreign antigens such as viruses and bacteria and cancer. On the other hand, it is known that excessive T cell activation is involved in the development of autoimmune diseases and causes adverse reactions to the human body such as rejection associated with transplantation. It is considered to be a promising therapeutic target in these diseases (Non-patent Document 1). This includes rejection in organ transplantation such as kidney transplantation, liver transplantation, heart transplantation, lung transplantation, pancreas transplantation, small intestine transplantation, rejection in bone marrow transplantation, graft-versus-host disease, Behcet's disease, psoriasis vulgaris, pustular In diseases such as psoriasis, psoriatic erythroderma, arthritic psoriasis, aplastic anemia, erythroblastosis, nephrotic syndrome, systemic myasthenia gravis, atopic dermatitis, ulcerative colitis, It is also clear from the fact that calcineurin inhibitors (Tacrolimus and Cyclosporin A), which are drugs that suppress activation, are approved in Japan as prophylactic or therapeutic agents (Non-patent Documents 2 and 3).
The PKC family consists of at least 12 types and is known to be expressed in various tissues. In addition, the PKC family is expressed in immunocompetent cells such as T cells, B cells, and macrophages and plays an important role in various immune responses, and is therefore considered to be involved in immune diseases and inflammatory diseases (non-) Patent Document 4).
Among them, PKC-θ is a phosphorylase that is selectively expressed in T cells, plays a role in the activation of T cells, is responsible for the transmission of stimuli to T cell receptors into cells. .
Inhibition of PKC-θ is known to suppress T cell activation (Non-patent Document 5), and PKC-θ-deficient mice are used in multiple sclerosis models, inflammatory bowel disease models, grafts. It has been reported to be resistant in somatic host disease models, rheumatoid arthritis models, and asthma models (Non-Patent Documents 6 to 8).
Based on the above, PKC (eg, PKC-θ) inhibitors are used for rejection in organ transplantation such as kidney transplantation, liver transplantation, heart transplantation, lung transplantation, pancreatic transplantation, small intestine transplantation, rejection reaction in bone marrow transplantation, graft Anti-host disease, Behcet's disease, psoriasis vulgaris, pustular psoriasis, erythrodermic psoriasis, psoriatic arthritis, aplastic anemia, erythroblastosis, nephrotic syndrome, systemic myasthenia gravis, atopic dermatitis It becomes a prophylactic or therapeutic agent in various immune diseases and inflammatory diseases such as ulcerative colitis and asthma.
