Description

本発明はリン酸化MBP産生促進剤に関し、更に詳細には、ミエリン形成改善効果や、脱髄疾患の予防および/または治療効果を有するリン酸化MBP産生促進剤に関する。   The present invention relates to a phosphorylated MBP production promoter, and more particularly, to a phosphorylated MBP production promoter having an effect of improving myelination and preventing and / or treating demyelinating diseases.

中枢神経系に存在するミエリンは、オリゴデンドロサイトの細胞膜が延長され、渦状に巻かれたものである。しかし、実際は、ミエリンを構成する細胞膜の細胞質側同士がミエリン・ベーシック・プロテイン(MBP)によって強固に接着される特殊機構によってミエリンは厚密化されている。この厚密化機構によりミエリンの水分含有量は極めて低くなり、神経細胞の軸索を絶縁することが可能となる。このようにミエリンの主機構の絶縁と関係することから、MBPの重要性が理解しうるが、さらにMBPはミエリン形成開始のシグナルとして働いているともいわれている。すなわち、MBP遺伝子は、7つのエクソンを持ち、選択的スプライシングによって主に4種類のアイソフォームが産生されるが、特にエクソン2を含む2種類のMBPアイソフォームは核内に移行してミエリン形成を制御しているとされている。   Myelin, which exists in the central nervous system, is an oligodendrocyte cell membrane that is elongated and spirally wound. However, in reality, myelin is thickened by a special mechanism in which the cytoplasmic sides of the cell membrane constituting myelin are firmly adhered to each other by myelin basic protein (MBP). Due to this thickening mechanism, the water content of myelin is extremely low, and it becomes possible to insulate nerve cell axons. Thus, the importance of MBP can be understood because it is related to the insulation of the main mechanism of myelin, but MBP is also said to act as a signal for initiating myelin formation. That is, the MBP gene has seven exons, and four types of isoforms are mainly produced by alternative splicing. In particular, two types of MBP isoforms including exon 2 migrate into the nucleus and form myelin. It is said that it is in control.

ところで、上記MBPには、いくつかの修飾体があり、そのうちリン酸化MBPは脱随疾患では低下することが知られている。本発明者らは、先に、MBPのリン酸化について研究を行い、リン酸化MBPが脱随防止や、再ミエリン化と深く関係していることを知った。   By the way, there are some modifications in the MBP, and it is known that phosphorylated MBP decreases in a degenerative disease. The present inventors have previously studied the phosphorylation of MBP, and found that phosphorylated MBP is deeply related to prevention of detachment and remyelination.

このように、リン酸化MBPの増加は、脱随防止や、再ミエリン化を通じて神経細胞の老化を防止することが期待されるが、有効かつ十分にリン酸化MBPを増加させることのできる薬剤が知られていないのが実情であった。   Thus, an increase in phosphorylated MBP is expected to prevent aging of nerve cells through prevention of detachment and remyelination, but there are known drugs that can effectively and sufficiently increase phosphorylated MBP. It was the actual situation that was not done.

従って本発明は、有効にリン酸化MBPを増加させることのできる物質を見出し、これを利用するリン酸化MBP産生促進剤を提供することである。   Therefore, the present invention is to find a substance capable of effectively increasing phosphorylated MBP and to provide a phosphorylated MBP production promoter utilizing this substance.

本発明者らは、上記課題を解決すべく、特に生薬成分に注目してそれらの薬理効果を検討していたところ、生薬である陳皮に多く含まれるヘスペリジンやナリルチンは優れたリン酸化MBP産生促進作用を有することを見出し、本発明を完成した。   In order to solve the above problems, the present inventors have been studying their pharmacological effects by paying particular attention to herbal components. Hesperidin and nariltin, which are contained in a large amount of herbal medicine, are excellent in promoting the production of phosphorylated MBP. It discovered that it had an effect | action, and completed this invention.

すなわち本発明は、ヘスペリジンおよび/またはナリルチンを有効成分として含有するリン酸化MBP産生促進剤である。   That is, the present invention is a phosphorylated MBP production promoter containing hesperidin and / or nariltin as an active ingredient.

本発明のリン酸化MBP産生促進剤は、老化等により減少するリン酸化MBPの量を増加させることができるものであり、脱随防止や、神経細胞の再ミエリン化に有効である。   The phosphorylated MBP production promoter of the present invention can increase the amount of phosphorylated MBP that decreases due to aging and the like, and is effective in preventing detachment and remyelination of nerve cells.

本発明において有効成分として使用されるヘスペリジンやナリルチンは、何れもフラバン配糖体であり、下記式で示されるものである。   Hesperidin and nariltin used as active ingredients in the present invention are both flavan glycosides and are represented by the following formula.

Furthermore, a skin containing a mixture of these may be used.

本発明のリン酸化MBP産生促進剤は、上記したヘスペリジンおよび/またはナリルチンを有効成分とし、他の医薬用担体と適宜混合し、これを経口剤あるいは非経口剤として製剤化することにより製造することができる。   The phosphorylated MBP production promoter of the present invention is produced by using the above-described hesperidin and / or nariltin as an active ingredient, mixing with other pharmaceutical carriers as appropriate, and formulating this as an oral or parenteral preparation. Can do.

経口剤としては、粉剤、散剤、顆粒剤、錠剤、カプセル剤、軟カプセル剤、液剤等とすることができ、これに応じた医薬用担体、例えば、デンプン、乳糖、白糖、マンニット、カルボキシメチルセルロース、コーンスターチ、無機塩等を利用することができる。また、経口剤の調製にあたっては、更に結合剤、崩壊剤、界面活性剤、滑沢剤、流動性促進剤、矯味剤、着色剤、香料等を配合することができる。   Oral preparations can be powders, powders, granules, tablets, capsules, soft capsules, liquids, etc., and pharmaceutical carriers corresponding thereto, such as starch, lactose, sucrose, mannitol, carboxymethylcellulose Corn starch, inorganic salt, etc. can be used. In preparation of the oral preparation, a binder, a disintegrant, a surfactant, a lubricant, a fluidity promoter, a corrigent, a colorant, a fragrance and the like can be further blended.

また、非経口剤も常法に従って製造され、希釈剤として一般に注射用蒸留水、生理食塩水、ブドウ糖水溶液、注射用植物油、ゴマ油、ラッカセイ油、ダイズ油、トウモロコシ油、プロピレングリコール、ポリエチレングリコール等を用いることができる。更に、必要に応じて、殺菌剤、防腐剤、安定剤を加えてもよい。   Parenteral preparations are also produced according to conventional methods. As diluents, distilled water for injection, physiological saline, aqueous glucose solution, vegetable oil for injection, sesame oil, peanut oil, soybean oil, corn oil, propylene glycol, polyethylene glycol and the like are generally used. Can be used. Furthermore, you may add a bactericidal agent, antiseptic | preservative, and a stabilizer as needed.

更に、この非経口剤は安定性の点から、バイアル等に充填後冷凍し、通常の凍結乾燥技術により水分を除去し、使用直前に凍結乾燥物から液剤を再調製することもできる。更にまた、必要に応じて適宜、等張化剤、安定剤、防腐剤、無痛化剤等を加えてもよい。その他の非経口剤としては、外用液剤、軟膏等の塗布剤、直腸内投与のための坐剤等が挙げられ、これらは何れも常法に従って製造される。   Furthermore, from the viewpoint of stability, this parenteral preparation can be frozen after filling into a vial or the like, the water can be removed by a normal freeze-drying technique, and the liquid preparation can be re-prepared from the freeze-dried product immediately before use. Furthermore, tonicity agents, stabilizers, preservatives, soothing agents and the like may be added as necessary. Examples of other parenteral preparations include coating solutions for external use, ointments and the like, suppositories for rectal administration, etc., all of which are manufactured according to conventional methods.

本発明のリン酸化MBP産生促進剤において、有効成分であるヘスペリジンおよび/またはナリルチンの配合量は、対象疾患、疾患程度、患者年齢等によっても相違するが、例えば、ヘスペリジンまたはナリルチンのみを有効成分とする経口製剤の場合は、大人一人当たり一日量として、0.1ないし1000mg程度であり、1ないし100mgとすることが好ましい。更に、ヘスペリジンとナリルチンの双方を有効成分とする経口製剤の場合は、前記投与量を参考にして決めればよい。   In the phosphorylated MBP production promoter of the present invention, the compounding amount of hesperidin and / or nariltin, which are active ingredients, varies depending on the target disease, disease level, patient age, etc., but for example, only hesperidin or nariltin is the active ingredient. In the case of an oral preparation, the daily dose per adult is about 0.1 to 1000 mg, preferably 1 to 100 mg. Furthermore, in the case of an oral preparation containing both hesperidin and nariltin as active ingredients, the dosage may be determined with reference to the above dose.

なお、既に漢方薬として公知の人参養栄湯には、上記のヘスペリジンおよびナリルチンが高い濃度で含まれているので、ヘスペリジンおよび/またはナリルチンに代え、これを本発明のリン酸化MBP産生促進剤の有効成分として使用することもできる。   In addition, since the above-mentioned hesperidin and nariltin are contained in Ninsengyoeito, which is already known as a traditional Chinese medicine, at a high concentration, it is replaced with hesperidin and / or nariltin, which is effective for the phosphorylated MBP production promoter of the present invention. It can also be used as an ingredient.
