  • JAK family (JAK1-3, TYK2) is a tyrosine kinase essential for cytokines to exert their biological activities. JAK is activated in the cell after the cytokine binds to the receptor, and activates the transcription factor Stat downstream thereof. JAK1 and JAK2 are widely expressed in vivo, while JAK3 is locally expressed in blood cells. This deficiency in JAK3 resulted in lymphocyte differentiation and proliferation failure in both humans and mice and exhibited severe combined immunodeficiency (SCID) (Japanese Journal of Clinical Immunology, 32, (2) 85. (2009) (Non-Patent Document 1)). This suggests that immunosuppression occurs by blocking signal pathways via JAK3. Therefore, a compound that inhibits JAK3 is expected to have an effect of controlling an immune response and is expected to be useful for the prevention and / or treatment of various autoimmune diseases.

Description

ウレイド基とアミノカルボニル基を置換基として有するチオフェン誘導体を有効成分として含有する新規JAK3阻害剤Novel JAK3 inhibitor containing as an active ingredient a thiophene derivative having a ureido group and an aminocarbonyl group as substituents
 本発明はウレイド基とアミノカルボニル基を置換基として有するチオフェン誘導体またはその塩の少なくとも一つを有効成分として含有する新規JAK3阻害剤、およびウレイド基とアミノカルボニル基を置換基として有する新規チオフェン誘導体またはその塩に関する。本発明のJAK3阻害剤は、JAK3が関与するとされる疾患の予防および/または治療剤として有用であることが期待される。また本発明は、チオフェン誘導体またはその塩を用いた、JAK3が関与するとされる疾患の予防および/または治療方法に関する。本発明はさらに、チオフェン誘導体またはその塩の、JAK3阻害剤を製造するための使用にも関する。 The present invention relates to a novel JAK3 inhibitor containing at least one of a thiophene derivative having a ureido group and an aminocarbonyl group as a substituent or a salt thereof as an active ingredient, and a novel thiophene derivative having a ureido group and an aminocarbonyl group as a substituent, or Relates to the salt. The JAK3 inhibitor of the present invention is expected to be useful as a preventive and / or therapeutic agent for a disease in which JAK3 is involved. The present invention also relates to a method for preventing and / or treating a disease that involves JAK3, using a thiophene derivative or a salt thereof. The present invention further relates to the use of a thiophene derivative or a salt thereof for producing a JAK3 inhibitor.
 JAKファミリー(JAK1~3、TYK2)は、サイトカインがその生物活性を発揮するために必須のチロシンキナーゼである。JAKはサイトカインが受容体へ結合後、細胞内で活性化され、その下流において転写因子Statを活性化する。JAK1とJAK2は生体内において広範に発現しているが、JAK3は血球系細胞において限局的に発現している。このJAK3の欠損はヒト、マウス何れにおいてもリンパ球系細胞の分化・増殖不全を来たし重症複合型免疫不全症(Severe Combined Immunodefiency;SCID)を呈する(Japanese Journal of Clinical Immunology, 32,(2) 85 (2009)(非特許文献1))。このことは、免疫抑制がJAK3を介したシグナル経路の遮断により生じることを示唆している。従って、JAK3を阻害する化合物には、免疫応答の制御作用が見込まれ、各種自己免疫疾患などの予防および/または治療に有用であることが期待される。 The JAK family (JAK1-3, TYK2) is a tyrosine kinase essential for cytokines to exert their biological activities. JAK is activated in the cell after the cytokine binds to the receptor, and activates the transcription factor Stat downstream thereof. JAK1 and JAK2 are widely expressed in vivo, while JAK3 is locally expressed in blood cells. This deficiency in JAK3 resulted in lymphocyte differentiation and proliferation failure in both humans and mice and exhibited severe combined immunodeficiency (SCID) (Japanese Journal of Clinical Immunology, 32, (2) 85. (2009) (Non-Patent Document 1)). This suggests that immunosuppression occurs by blocking signal pathways via JAK3. Therefore, a compound that inhibits JAK3 is expected to have an effect of controlling an immune response and is expected to be useful for the prevention and / or treatment of various autoimmune diseases.
 既存のJAK3を阻害する化合物としては、ピロロピリミジン骨格を有する化合物(Bioorganic & Medicinal Chemistry Letters, 16, 5633 (2006)(非特許文献2))、四環性ピリドン骨格を有する化合物(Bioorganic & Medicinal Chemistry Letters, 12, 1219 (2002)(非特許文献3))、オキシインドール骨格を有する化合物(非特許文献2)などが知られている。 As compounds that inhibit existing JAK3, compounds having a pyrrolopyrimidine skeleton (Bioorganic & Medicinal Chemistry Letters, 16, 5633 (2006) (Non-patent Document 2)), compounds having a tetracyclic pyridone skeleton (Bioorganic & Medicinal Chemistry) Letters, 12, 1219 (2002) (non-patent document 3)), compounds having an oxindole skeleton (non-patent document 2), and the like are known.
 一方、ウレイド基とアミノカルボニル基を置換基として有するチオフェン誘導体が、IKK-2阻害剤として知られている(The Journal of Pharmacology and Experimental Therapeutics, 312, 373 (2005)(非特許文献4))。 On the other hand, thiophene derivatives having a ureido group and an aminocarbonyl group as substituents are known as IKK-2 inhibitors (The Journal of Pharmacology and Experimental Therapeutics, 312, 373 (2005) (Non-Patent Document 4)).
 しかしながら、本願に係るウレイド基とアミノカルボニル基を置換基として有するチオフェン誘導体がJAK3に対して阻害活性を有することについては全く知られていない。 However, it is not known at all that the thiophene derivative having a ureido group and an aminocarbonyl group as substituents according to the present application has an inhibitory activity against JAK3.
 新規JAK3阻害剤を見出すこと、およびJAK3阻害活性を有する新規化学構造の化合物を見出すことは非常に興味深い課題である。 Finding a novel JAK3 inhibitor and finding a compound with a novel chemical structure having JAK3 inhibitory activity are very interesting issues.
 本発明者らは、どのような化学構造の化合物がJAK3阻害活性を有するかについて、鋭意探索研究を行った結果、ウレイド基とアミノカルボニル基を置換基として有するチオフェン誘導体がJAK3阻害活性を有することを見出した。 As a result of intensive research on the chemical structure of a compound having JAK3 inhibitory activity, the present inventors have found that a thiophene derivative having a ureido group and an aminocarbonyl group as substituents has JAK3 inhibitory activity. I found.
 さらに、ウレイド基とアミノカルボニル基を置換基として有する新規チオフェン誘導体を数多く合成し、それらの化合物の薬理作用を鋭意探索研究した結果、それらの化合物においてもJAK3阻害活性を有することを見出し、本発明を完成させた。 Furthermore, as a result of synthesizing a large number of novel thiophene derivatives having ureido groups and aminocarbonyl groups as substituents, and intensively researching the pharmacological action of these compounds, it was found that these compounds also have JAK3 inhibitory activity.
