Definitions
- the present invention relates to a novel nitrocatechol derivative or salt thereof having a catechol-O-methyltransferase (COMT) inhibitory action and a dopa decarboxylase (DDC) inhibitory action, and a pharmaceutical composition containing them.
- a catechol-O-methyltransferase (COMT) inhibitory action and a dopa decarboxylase (DDC) inhibitory action
- DDC dopa decarboxylase
- Parkinson's disease is caused by the degeneration of dopaminergic nerves in the substantia nigra of the brain and the ventral tegmental area. It is a progressive neurodegenerative disease characterized by movement disorders due to muscle stiffness.
- Surgical treatment includes, for example, deep brain electrical stimulation therapy by stereotaxic brain surgery, but it requires electrode mounting to the brain and implantation of a chest stimulation device. Risk of cerebral hemorrhage is great.
- pharmacotherapy includes adenosine A2a receptor antagonists as new mechanism drugs. Even today, dopamine replacement therapy with L-dopa is most effective. Treatment. L-dopa is a precursor of dopamine and is metabolized by dopamine and exerts its action after moving into the brain. However, L-dopa is rapidly metabolized by peripheral COMT and DDC upon entering the body and has a short blood half-life. Therefore, each inhibitor is administered at the same time, and L-dopa is reduced to half in blood. Prolonging the period and increasing the amount of L-dopa transferred into the brain and the amount of dopamine produced in the brain are effective means for improving motor symptoms (Non-patent Document 1).

Provided are a novel nitrocatechol derivative having COMT inhibitory effect and DDC inhibitory effect or a salt thereof and a medicinal composition comprising the same. A compound represented by general formula (1) or a pharmaceutically acceptable salt thereof, and a medicinal composition comprising the same.
Description
本発明は、カテコール－Ｏ－メチルトランスフェラーゼ（ＣＯＭＴ）阻害作用およびドパデカルボキシラーゼ（ＤＤＣ）阻害作用を有する新規ニトロカテコール誘導体又はその塩、およびこれらを含有する医薬組成物に関する。
The present invention relates to a novel nitrocatechol derivative or salt thereof having a catechol-O-methyltransferase (COMT) inhibitory action and a dopa decarboxylase (DDC) inhibitory action, and a pharmaceutical composition containing them.
パーキンソン病は、脳の黒質緻密部、腹側被蓋野にあるドパミン作動性神経の変性に伴い、神経伝達物質であるドパミンの減少により、無動・寡動、安静時振戦、姿勢反射障害、筋固縮による運動障害を特徴とする進行性の神経変性疾患である。
Parkinson's disease is caused by the degeneration of dopaminergic nerves in the substantia nigra of the brain and the ventral tegmental area. It is a progressive neurodegenerative disease characterized by movement disorders due to muscle stiffness.
近年、日本においては高齢化に伴い１０万人に１００～１５０人、欧米においても１５０～２００人と有病率は増加傾向にある。発症は中高齢に多く、高齢になるほど発病率が増加傾向にある。また、若年性パーキンソン病と呼ばれる４０歳以下で発症する例もあり、この中には遺伝子異常が明らかにされた症例もある。
In recent years, the prevalence rate has been increasing in Japan with 100-150 people per 100,000 people and 150-200 people in Europe and America with the aging of the population. The onset is common in middle-aged and older people, and the incidence tends to increase with increasing age. In addition, there is a case called juvenile Parkinson's disease that develops at the age of 40 years or younger.
パーキンソン病の治療には、外科的療法と薬物療法がある。外科的治療としては、例えば定位脳手術による深部脳電気刺激療法があるが、脳への電極装着と胸部刺激装置の埋め込みを必要とし、高齢者には負担が大きく、機器の高磁場による影響、脳内出血等のリスクが大きい。
There are two types of treatment for Parkinson's disease: surgical therapy and drug therapy. Surgical treatment includes, for example, deep brain electrical stimulation therapy by stereotaxic brain surgery, but it requires electrode mounting to the brain and implantation of a chest stimulation device. Risk of cerebral hemorrhage is great.
薬物療法としては、ドパミン受容体刺激薬やモノアミン酸化酵素Ｂ阻害薬の他、新しい機序の薬としてアデノシンＡ２ａ受容体拮抗薬などがあるが、現在でもＬ－ドパによるドパミン補充療法が最も効果的な治療法である。Ｌ－ドパはドパミンの前駆物質であり、脳内へ移行した後、ドパミンに代謝され作用を発揮する。しかしながら、Ｌ－ドパは体内に入ると速やかに末梢のＣＯＭＴおよびＤＤＣにより代謝され、血中半減期が短い欠点があるため、それぞれの阻害薬を同時に投与し、Ｌ－ドパの血中半減期を延長させ、Ｌ－ドパの脳内への移行量および脳内でのドパミン生成量を増大させることが運動症状改善の有効な手段となる（非特許文献１）。
In addition to dopamine receptor stimulants and monoamine oxidase B inhibitors, pharmacotherapy includes adenosine A2a receptor antagonists as new mechanism drugs. Even today, dopamine replacement therapy with L-dopa is most effective. Treatment. L-dopa is a precursor of dopamine and is metabolized by dopamine and exerts its action after moving into the brain. However, L-dopa is rapidly metabolized by peripheral COMT and DDC upon entering the body and has a short blood half-life. Therefore, each inhibitor is administered at the same time, and L-dopa is reduced to half in blood. Prolonging the period and increasing the amount of L-dopa transferred into the brain and the amount of dopamine produced in the brain are effective means for improving motor symptoms (Non-patent Document 1).
ＤＤＣ阻害薬としては、カルビドパ（（－）－Ｌ－α－ヒドラジノ－アルファ－メチル－β－（３，４－ジヒドロキシベンゼン）プロピオン酸一水和物）があり、合剤としてＬ－ドパと併用されるが、病気の進行にともない効果持続時間が短縮し、ウェアリングオフ現象と呼ばれる運動症状の日内変動がみられるようになる。そのため、さらにＣＯＭＴ阻害薬を併用して血中Ｌ－ドパ濃度を上昇させることで症状の改善を図る必要がある（非特許文献２）。
As a DDC inhibitor, there is carbidopa ((−)-L-α-hydrazino-alpha-methyl-β- (3,4-dihydroxybenzene) propionic acid monohydrate). Although it is used in combination, the duration of the effect is shortened as the disease progresses, and diurnal movements of the motor symptoms called wear-off phenomenon are observed. For this reason, it is necessary to further improve symptoms by increasing the L-DOPA concentration in the blood in combination with a COMT inhibitor (Non-patent Document 2).
ＣＯＭＴ阻害薬としては、カテコール系化合物が多く開発されているが（例えば、非特許文献３、特許文献１～７）、中でもエンタカポン（（Ｅ）－２－シアノ－Ｎ，Ｎ－ジエチル－３－（３，４－ジヒドロキシ－５－ニトロフェニル）アクリルアミド）が多くの患者に使用されているが、作用が弱く、持続性に欠ける問題点を有している（非特許文献４）。また、トルカポン（３，４－ジヒドロキシ－４’－メチル－５－ニトロベンゾフェノン）は肝機能障害が報告されている（非特許文献５）。更に近年、より強力で持続的なＣＯＭＴ阻害薬であるオピカポン（５－［３－（２，５－ジクロロ－４，６－ジメチル－１－オキシ－ピリジン－３－イル）－［１，２，４］オキサジアゾール－５－イル］－３－ニトロベンゼン－１，２－ジオール）が開発された（非特許文献６）。
As COMT inhibitors, many catechol compounds have been developed (for example, Non-Patent Document 3, Patent Documents 1 to 7), and among them, entacapone ((E) -2-cyano-N, N-diethyl-3- (3,4-Dihydroxy-5-nitrophenyl) acrylamide) has been used in many patients, but has a problem that its action is weak and lacks durability (Non-patent Document 4). In addition, tolcapone (3,4-dihydroxy-4'-methyl-5-nitrobenzophenone) has been reported to have impaired liver function (Non-patent Document 5). More recently, opicapon (5- [3- (2,5-dichloro-4,6-dimethyl-1-oxy-pyridin-3-yl)-[1,2,2], a more potent and long-lasting COMT inhibitor. 4] oxadiazol-5-yl] -3-nitrobenzene-1,2-diol) (Non-Patent Document 6).
しかしながら、ＣＯＭＴ阻害薬とＤＤＣ阻害薬が併用される場合は、それぞれの薬において作用の発現時間や持続性が異なるため、血中Ｌ－ドパ濃度の調節が困難であり、期待されたほどの効果が得られなかったり、効きすぎることによりジスキネジアなどの副作用が発現するといった問題が生じる。
However, when a COMT inhibitor and a DDC inhibitor are used in combination, since the onset time and the duration of action of each drug are different, it is difficult to adjust the blood L-dopa concentration, and as expected There are problems that side effects such as dyskinesia appear due to inefficiency or excessive effect.
したがって、ＣＯＭＴ阻害とＤＤＣ阻害の二つの作用を有する医薬化合物であれば、両作用を同時に発現することによりＬ－ドパの調節が容易になると考えられ、また、患者の利便性と服薬コンプライアンス面からも、新規なデュアル阻害薬の開発が望まれている。
Therefore, it is considered that a pharmaceutical compound having two actions of COMT inhibition and DDC inhibition can facilitate the regulation of L-dopa by expressing both actions simultaneously, and also improves patient convenience and compliance. Therefore, development of a novel dual inhibitor is desired.
本発明の課題は、ＣＯＭＴ阻害作用およびＤＤＣ阻害作用を有する新規ニトロカテコール誘導体又はその塩、及びそれらを含有する医薬組成物を提供することにある。
An object of the present invention is to provide a novel nitrocatechol derivative having a COMT inhibitory action and a DDC inhibitory action or a salt thereof, and a pharmaceutical composition containing them.
本発明者らは上記課題を解決するため鋭意検討した結果、式（１）で表されるＣＯＭＴおよびＤＤＣのデュアル阻害作用を有する、新規ニトロカテコール誘導体を見出すに至った。
As a result of intensive studies to solve the above problems, the present inventors have found a novel nitrocatechol derivative having a dual inhibitory action of COMT and DDC represented by the formula (1).
