Description

含窒素複素環誘導体Nitrogen-containing heterocyclic derivatives
 本発明は、Apoptosis signal-regulating kinase 1(以下、ASK1と表す場合もある)阻害活性を有し、例えば、筋萎縮性側索硬化症(Amyotrophic lateral sclerosis、以下、ALSと表す場合もある)の予防及び/又は治療剤として有用な含窒素複素環誘導体又はその薬学的に許容される塩等に関する。 The present invention has inhibitory activity on Apoptosis signal-regulating kinase 1 (hereinafter also referred to as ASK1), for example, amyotrophic lateral sclerosis (hereinafter also referred to as ALS). The present invention relates to a nitrogen-containing heterocyclic derivative useful as a preventive and / or therapeutic agent or a pharmaceutically acceptable salt thereof.
 MAPキナーゼ(mitogen-activated protein kinase、以下、MAPKと表す)カスケードは、サイトカインレセプター刺激や物理化学ストレス等の多様な刺激により活性化したMAPKキナーゼキナーゼ(以下、MAPKKKと表す)が下流のMAPKキナーゼ(以下、MAPKKと表す)をリン酸化することによりMAPKKを活性化し、活性化したMAPKKが更に下流のMAPKをリン酸化するという、真核生物に共通かつ普遍的に存在するシグナル伝達系である。MAPKカスケードは、細胞においては増殖や生存、分化、アポトーシス等、種々の細胞応答を誘導すると共に、個体レベルでは、癌、炎症、虚血性疾患、神経変性疾患等の様々な病態において重要な役割を果たしている。 The MAP kinase (mitogen-activated protein kinase, hereinafter referred to as MAPK) cascade is a downstream MAPK kinase (hereinafter referred to as MAPKKK) activated by various stimuli such as cytokine receptor stimulation and physicochemical stress. This is a signal transduction system that is common and universal in eukaryotes, in which MAPKK is activated by phosphorylating (hereinafter referred to as MAPKK), and the activated MAPKK further phosphorylates downstream MAPK. The MAPK cascade induces various cellular responses such as proliferation, survival, differentiation, and apoptosis in cells, and at the individual level, it plays an important role in various pathologies such as cancer, inflammation, ischemic diseases, and neurodegenerative diseases. Plays.
 ASK1はMAPKKKの一つであり、サイトカインレセプター刺激のほか、酸化ストレスや小胞体ストレス等の物理化学ストレスによっても強く活性化される。構成的活性化型ASK1を細胞に過剰発現させると、SEK1-JNK経路とMKK3/6-p38経路を選択的に活性化すると共にアポトーシスを惹起する。一方、上皮細胞や未分化な神経細胞においては、ASK1の活性化を介してp38を活性化する経路が分化や生存を誘導することも報告されている。従って、ASK1は細胞の生死を制御するだけでなく、分化においても重要な役割を果たしていると考えられる。 ASK1 is one of MAPKKK and is strongly activated not only by cytokine receptor stimulation but also by physicochemical stress such as oxidative stress and endoplasmic reticulum stress. When constitutively activated ASK1 is overexpressed in cells, it selectively activates the SEK1-JNK pathway and the MKK3 / 6-p38 pathway and induces apoptosis. On the other hand, in epithelial cells and undifferentiated neurons, it has also been reported that a pathway that activates p38 through activation of ASK1 induces differentiation and survival. Therefore, ASK1 is thought to play an important role not only in controlling cell survival but also in differentiation.
 ALSは、運動神経が特異的に障害される進行性疾患である。ALSは、主に壮年期に発症し、筋萎縮が徐々に全身に広がり、歩行困難、言語障害、嚥下障害、呼吸障害に及び、気管切開/人工呼吸器装着等を施さなければ発症後3~5年で死に至るきわめて重篤な疾患である。ALSは、「難病性疾患克服研究事業対象疾患」に指定されているにもかかわらず、日本国内での患者数は約7000人と、他の神経変性疾患(アルツハイマー病、パーキンソン病等)に比べて患者数が少ないため、治療薬開発への取り組みが遅れている。現在の治療法は、適度なリハビリテーションによる筋力低下予防と、唯一の保険適応薬剤であるリルゾール(グルタミン酸の神経終末放出を抑制する薬物)による一時的な病態進行の遅延だけであり、ALSの病態分子メカニズムに基づく根本的な治療法は皆無である。 ALS is a progressive disease in which motor nerves are specifically damaged. ALS develops mainly in the middle period, and muscle atrophy gradually spreads throughout the body. It is difficult to walk, speech disorder, dysphagia, respiratory disorder, and 3 to 3 after the onset unless tracheostomy / ventilator is used. It is a very serious disease that will die in 5 years. Despite being designated as a “target disease for intractable disease overcoming research project”, ALS has approximately 7,000 patients in Japan, compared with other neurodegenerative diseases (Alzheimer's disease, Parkinson's disease, etc.). Due to the small number of patients, efforts to develop therapeutic drugs are delayed. The current treatment is only prevention of muscle weakness by moderate rehabilitation and temporary delay in the progression of disease due to riluzole (a drug that suppresses the release of glutamate nerve endings), the only insurance indication drug. There is no fundamental cure based on the mechanism.
 ALSの原因を解明する上でのブレイクスルーは、家族性ALSの原因遺伝子として1993年にRosenらによって同定されたCu/Zn superoxide dismutase 1(SOD1)の遺伝子変異の発見である。全ALS患者のうち約10%が家族性であり、そのうちの約20%がSOD1遺伝子変異による。原因遺伝子であるSOD1の発見は、家族性ALSのみならず孤発性ALSの病態解明にも飛躍的な進歩をもたらすものと期待されているが、ALSに共通する病態を説明しうる分子メカニズムは明らかにされていない。SOD1遺伝子上には、これまで100種類以上の点変異が報告されており、それらの多くが優性遺伝形式をとること、幾つかの変異型SOD1トランスジェニックマウスがALSと類似した症状を呈すること、ならびにSOD1タンパク質の機能喪失によっては病態を発症しないこと等から、変異型SOD1タンパク質が何らかの獲得性神経細胞毒性を発揮し、運動神経細胞死とそれに伴う個体の神経症状をもたらすものと考えられている。しかし、その際に変異型SOD1が細胞内でどのようなシグナルを発信し、どのようなメカニズムで細胞を傷害するかという点については不明である。 A breakthrough in elucidating the cause of ALS is the discovery of a mutation in Cu / Zn superoxide dismutase 1 (SOD1), identified by Rosen et al. In 1993 as a causative gene for familial ALS. About 10% of all ALS patients are familial, of which about 20% are due to SOD1 gene mutations. The discovery of the causative gene, SOD1, is expected to bring about dramatic progress in elucidating the pathogenesis of sporadic ALS as well as familial ALS, but the molecular mechanism that can explain the pathophysiology common to ALS is It has not been revealed. More than 100 types of point mutations have been reported so far on the SOD1 gene, many of them adopt a dominant inheritance form, some mutant SOD1 transgenic mice exhibit symptoms similar to ALS, In addition, it is considered that mutant SOD1 protein exerts some acquired neurocytotoxicity and causes motor neuron death and accompanying neurological symptoms due to loss of function of SOD1 protein. . However, at this time, it is unclear what signal the mutant SOD1 emits in the cell and what mechanism damages the cell.
 一條らは、ALSにおける変異型SOD1による神経細胞死分子メカニズムとして、小胞体ストレスが深く関与していることを明らかにしている(Genes Dev. 2008年, Jun 1;22(11):1451-64頁)。すなわち、変異型SOD1が特異的に結合する標的タンパク質の一つとして、小胞体の品質管理に重要な役割を担う小胞体膜タンパク質Derlin-1を同定し、その結合が神経細胞の小胞体品質管理機構の破綻をきたし、小胞体ストレスを惹起することを見出した。さらに、変異型SOD1依存的小胞体ストレス誘導による神経細胞死のメディエーターとして、ストレス応答性MAPキナーゼの一つであるASK1が関与することを明らかにしている。従って、ASK1の阻害剤は、ALSの予防及び/又は治療剤になり得る可能性がある。 Ichijo et al. Have revealed that endoplasmic reticulum stress is deeply involved as a neuronal death molecular mechanism by mutant SOD1 in ALS (Genes Dev. 2008, Jun 1; 22 (11): 1451-64 page). That is, we identified the endoplasmic reticulum membrane protein Derlin-1, which plays an important role in the quality control of the endoplasmic reticulum, as one of the target proteins to which the mutant SOD1 specifically binds. It has been found that the failure of the mechanism causes endoplasmic reticulum stress. Furthermore, it has been clarified that ASK1, one of stress-responsive MAP kinases, is involved as a mediator of neuronal cell death induced by mutant SOD1-dependent endoplasmic reticulum stress. Therefore, an ASK1 inhibitor may be a preventive and / or therapeutic agent for ALS.

 レンチウィルスを用いたSOD1(G93A)の過剰発現によって約80%の運動神経細胞死が起こることが示されている(Genes Dev. 2008年, Jun 1;22(11):1451-64頁)。一方、支持細胞であるGFAP陽性のグリア細胞は、SOD1(G93A)によって影響を受けない。これらの結果とほぼ同様の結果が、図1及び図2のコントロール群(溶媒DMSO投与群)において観察された。この運動神経細胞死実験系にASK1活性阻害剤(化合物6)を作用させたところ、0.1μM、0.3μM、1μMと濃度依存的に運動神経細胞死の抑制が観察された(図1)。しかしながら、3μMにおいては野生型SOD1を発現させた細胞においても、約70%の運動神経細胞死が観察され、化合物6による運動神経細胞毒性が認められた(図1)。また、グリア細胞においても、3μMでは約40%の細胞死が観察された(図2)。 It has been shown that overexpression of SOD1 (G93A) using lentivirus causes about 80% motor neuron death (Genes Dev. 2008, Jun 1; 22 (11): 1451-64). On the other hand, GFAP-positive glial cells that are support cells are not affected by SOD1 (G93A). Results similar to these results were observed in the control group (solvent DMSO administration group) of FIGS. When an ASK1 activity inhibitor (compound 6) was allowed to act on this motor neuron death experimental system, suppression of motor neuron death was observed in a concentration-dependent manner of 0.1 μM, 0.3 μM, and 1 μM (FIG. 1). However, at 3 μM, about 70% of motor neuron death was observed even in cells expressing wild-type SOD1, and motor neurotoxicity due to compound 6 was observed (FIG. 1). In addition, about 40% cell death was observed in glial cells at 3 μM (FIG. 2).
 従って、in vitro初代運動神経細胞培養の実験系においては、1μMまでの濃度において化合物6は変異型SOD1(G93A)依存的運動神経細胞死抑制効果があることが明らかとなった。 Therefore, in an experimental system for in vitro vitro primary motor neuron culture, compound 6 was found to have a mutant SOD1 (G93A) -dependent motor neuron death inhibitory effect at concentrations up to 1 μM.
 以上の結果より、本発明の化合物は、変異型SOD1(G93A)依存的運動神経細胞死抑制効果を介し、ALSの予防及び/又は治療剤として有望であることが示唆された。 From the above results, it was suggested that the compound of the present invention is promising as a preventive and / or therapeutic agent for ALS through the mutant SOD1 (G93A) -dependent motor neuron death inhibitory effect.

The drug administration group averaged 3 animals at 0 hours, 6 animals at 5 hours, the non-drug administration group averaged 3 animals at 0 hours, and 5 animals after 5 hours, and the data is the average +/- Shown by SEM.
<化合物7のFasによる肝障害に対する影響>
 マウス(C57BL/6、オス)20匹を2群に分け、一方の群(10匹)に化合物7を100 mg/kgで経口投与し(薬物投与群)、他方の群(10匹)には溶媒(10% DMSO, 10% Cremophore EL)を投与した(薬物非投与群)。薬物投与群及び薬物非投与群に90分後に0.4 μg/gの抗Fas抗体(Jo2, BD PharMingen社)を腹腔内投与した。各群の抗Fas抗体投与の0時間後、3.5時間後及び5時間後の血清中のALT値を測定した。薬物投与群は、0時間後は3匹、3.5時間後は3匹、5時間後は4匹の、薬物非投与群は、0時間後は3匹、3.5時間後は4匹、5時間後は3匹の平均を取り、データは平均+/- SEMで示した。
 結果を図3A(化合物6)、図3B(化合物7)に示す。
<Influence of Compound 7 on Fas Caused by Fas>
20 mice (C57BL / 6, male) were divided into 2 groups, and one group (10 mice) was orally administered Compound 7 at 100 mg / kg (drug administration group), the other group (10 mice) A solvent (10% DMSO, 10% Cremophore EL) was administered (drug non-administration group). After 90 minutes, 0.4 μg / g anti-Fas antibody (Jo2, BD PharMingen) was intraperitoneally administered to the drug administration group and the drug non-administration group. Serum ALT levels were measured at 0, 3.5, and 5 hours after administration of anti-Fas antibody in each group. The drug-administered group was 3 animals after 0 hours, 3 animals after 3.5 hours, 4 animals after 5 hours, and the non-drug-administered group was 3 animals after 0 hours, 4 animals after 3.5 hours, and 5 hours later Took the average of 3 animals and the data are shown as mean +/- SEM.
The results are shown in FIG. 3A (Compound 6) and FIG. 3B (Compound 7).
 C57BL/6マウスにJo2を投与するとALTが上昇し、肝障害が惹起された。しかしながら、Jo2投与の90分前に100 mg/kgの化合物6あるいは化合物7を投与すると、ALTが低下していることから肝障害が軽減されたことが分かった。従って、抗Fas抗体誘発肝障害実験系においては、化合物6および化合物7に肝障害軽減効果があることが明らかとなった。
 以上の結果より、本発明の化合物は、肝炎の予防及び/又は治療剤として有望であることが示唆された。
