Description

本発明は、マルチトールを有効成分とする終末糖化産物生成抑制剤、ならびにマルチトールを有効成分として含む、糖尿病もしくは糖尿病合併症の予防および/または治療のための医薬組成物に関する。   The present invention relates to a glycation end product production inhibitor containing maltitol as an active ingredient, and a pharmaceutical composition for preventing and / or treating diabetes or diabetic complications containing maltitol as an active ingredient.

アミノ酸と還元糖の混合物を加熱すると褐変する現象は、一般にメイラード反応と呼ばれ、食品分野では、食品の加熱処理や貯蔵中に生じる現象として知られている。メイラード反応は、生体内においても発生しており、1968年にはグリコシルヘモグロビン(HbA1c)が生体内で同定されたことにより、糖尿病や老化の進行に伴い蛋白質の糖化反応が進行することが明らかにされた。そして、近年では、蛋白質の糖化反応における終末糖化産物(Advanced glycation end products、以下「AGEs」とも称する)が糖尿病合併症や動脈硬化といった生活習慣病の発症や老化の進行に関与することが報告されている(非特許文献1〜3)。AGEsは特定の物質を指すものではなく、その全容は未だ解明されていないが、蛍光性や架橋構造の有無によって、ペントシジン、ピロピリジン、ピラリン等、様々な物質の存在が確認されている。   The phenomenon of browning when a mixture of amino acid and reducing sugar is heated is generally called the Maillard reaction, and is known in the food field as a phenomenon that occurs during heat treatment and storage of food. The Maillard reaction also occurs in vivo, and it was clear that glycosylation hemoglobin (HbA1c) was identified in vivo in 1968, leading to the progress of protein glycation with the progress of diabetes and aging. It was done. In recent years, advanced glycation end products (hereinafter also referred to as “AGEs”) in protein glycation reactions have been reported to be involved in the onset of lifestyle-related diseases such as diabetic complications and arteriosclerosis and the progression of aging. (Non-Patent Documents 1 to 3). AGEs do not refer to specific substances, and the whole of them has not yet been elucidated, but the presence of various substances such as pentosidine, pyropyridine, and pyralin has been confirmed depending on the presence of fluorescence and cross-linking structure.

生体内における蛋白質糖化反応の詳細は明らかとなっていないが、蛋白質に存在するアミノ基と還元糖に存在するアルデヒド基が反応し、シッフ塩基を形成した後、安定なアマドリ化合物が生成され、さらに長期の反応を経て、該アマドリ化合物から種々のAGEsが生成されると考えられている。アマドリ化合物からのAGEsの生成過程において、3−デオキシグルコソン(以下、「3−DG」とも称する)、グリオキサール、メチルグリオキサール等のジカルボニル化合物が中間体として生成することが知られている。これら中間体の中でも3−DGはアミノ基との反応性が極めて高く、且つ最も生成量が多いことから、重要な中間体と考えられている。また、糖尿病患者においては、血清3−DG値が高いほど合併症の進行が速いとの報告もある(非特許文献4)。したがって、AGEsの生成抑制のために3−DGの生成を抑制することが特に注目されている。   Details of the protein saccharification reaction in vivo have not been clarified, but after the amino group present in the protein reacts with the aldehyde group present in the reducing sugar to form a Schiff base, a stable Amadori compound is generated, It is considered that various AGEs are generated from the Amadori compound through a long-term reaction. It is known that dicarbonyl compounds such as 3-deoxyglucosone (hereinafter also referred to as “3-DG”), glyoxal, and methylglyoxal are generated as intermediates in the process of generating AGEs from Amadori compounds. Among these intermediates, 3-DG is considered to be an important intermediate because it has extremely high reactivity with amino groups and has the largest production amount. There is also a report that in diabetic patients, the higher the serum 3-DG level, the faster the complications progress (Non-Patent Document 4). Therefore, it has been particularly noticed to suppress the generation of 3-DG in order to suppress the generation of AGEs.

3−DGの生成抑制に着目した技術としては、3−DG等の初期グリコシル化産物のカルボニル基と反応して標的蛋白質の後期グリコシル化を抑制する、アミノグアニジン等の化合物を含むメイラード反応阻害剤が開示されている(特許文献1)。アミノグアニジンは当該技術分野における医薬品の開発において最も研究されている物質であるが、肝障害等の副作用を有することが確認されており、そのため、実用化には至っていない。   As a technique focused on the suppression of 3-DG production, a Maillard reaction inhibitor containing a compound such as aminoguanidine that reacts with a carbonyl group of an early glycosylation product such as 3-DG to suppress late glycosylation of a target protein Is disclosed (Patent Document 1). Aminoguanidine is the most studied substance in the development of pharmaceuticals in this technical field, but it has been confirmed that it has side effects such as liver damage and has not been put into practical use.

その他にも、ガンビールノキやシラカバ等の植物抽出物により3−DGの生成反応を阻害するメイラード反応阻害剤(特許文献2)、グリオキサラーゼI活性を備える酵素およびカルボニル化合物還元剤を有効成分とする3−DGの消去によるカルボニルストレス改善剤(特許文献3)、パラバン酸誘導体を有効成分とする3−DG生成阻害剤(特許文献4)、スルフィド化合物を有効成分とするデオキシグルコソン生成抑制剤(特許文献5)などが知られている。しかし、これらはいずれも有効性や安全性の点に課題を残すものであった。   In addition, a Maillard reaction inhibitor (Patent Document 2) that inhibits the 3-DG production reaction by plant extracts such as Gambirium and birch, and an enzyme having glyoxalase I activity and a carbonyl compound reducing agent as active ingredients Carbonyl stress ameliorating agent by elimination of 3-DG (Patent Document 3), 3-DG production inhibitor having a parabanic acid derivative as an active ingredient (Patent Document 4), Deoxyglucosone production inhibitor having a sulfide compound as an active ingredient ( Patent Document 5) is known. However, these all left problems in terms of effectiveness and safety.

そこで、種々の疾患の発症や悪化に関与するAGEsの生成抑制のために利用することができ、かつ、重篤な副作用を有さない安全性の高い薬剤が求められている。   Therefore, a highly safe drug that can be used for suppressing the production of AGEs involved in the onset and worsening of various diseases and that has no serious side effects is desired.
