- the present invention relates to a composition for inhibiting carnosine dipeptidase. More specifically, the present invention relates to a composition for inhibiting carnosine dipeptidase containing a predetermined compound such as polyphenol, the use of polyphenol or the like for inhibiting carnosine dipeptidase, and a method for inhibiting carnosine dipeptidase.
- the present invention also relates to a composition containing carnosine. More specifically, the present invention relates to a composition containing carnosine and a specific polyphenol.
- Carnosine is a dipeptide composed of ⁇ -alanine and histidine, and is present in high concentrations in muscle and nerve tissues in mammals such as humans.
- Carnosine's actions include (1) proton buffering activity, (2) calcium secretion and calcium sensitivity control, (3) antioxidant action, (4) metal ion chelate action, (5) histidine / histamine extracellular donor (6) Antihyperglycemic action, (7) Anti-inflammatory action, (8) Wrinkle formation inhibitory action, (9) Fatigue recovery promoting action, etc. are known.
- the action of carnosine it has been reported that production of glycation end products, inhibition of cell death due to cerebral ischemia, amyloid ⁇ accumulation inhibition action, immunoregulatory action, etc. in Alzheimer's disease (AD) model mice have been reported.
- AD Alzheimer's disease
- carnosine dipeptidase has two types, carnosine dipeptidase 1; CNDP1, and tissue carnosinase 2 (CNDP2). Both carnosine dipeptidase 1 and carnosine dipeptidase 2 are known to exhibit degrading activity against a dipeptide having a histidine residue at the carboxyl terminus (X-His (X is a natural amino acid)) (Non-patent Document 1). ), Carnosine is one of the dipeptides that are degraded. These carnosine dipeptidase 1 and carnosine dipeptidase 2 are proteins that are highly homologous to each other, although their tissue distribution and enzymatic properties are different. Of these, carnosine dipeptidase 1 has been shown to be active only in higher primates (human and large monkeys) in serum, but not in many other mammals (non-patented) Reference 2).
- Non-patent Document 1 phenanthroline has been reported as an inhibitor of the degrading enzyme.
- the phenanthroline is known to exhibit oral toxicity as a side effect while having enzyme inhibitory activity.
- there are few reports on other inhibitors and there are currently few known carnosine degradation inhibitors that focus on inhibiting the activity of carnosine dipeptidaseid1.
- carnosine dipeptidase 2 for example, bestatin is known as its inhibitor (Non-patent Document 3), and in addition, ⁇ -alanine and its derivatives are also effective in inhibiting carnosine dipeptidase 2. It has been reported (Patent Document 1).
- carnosine ⁇ dipeptidase 1 is a model in which human carnosine dipeptidase 1 is introduced into db / db mice, and diabetes-like symptoms such as increased fasting blood glucose level and HbA1c from a young age, and weight loss Is recognized (Non-Patent Document 4). That is, it has been suggested that enhanced carnosine degradation by carnosine dipeptidase 1 may cause disease onset. Therefore, the inhibitor of carnosineiddipeptidase 1 effectively delivers L-carnosine to plasma, target organs or other organs, and has a preventive effect on various diseases caused by diabetes, oxidative stress, and production of advanced glycation end products. It can be considered as an approach to increase it.
- Non-Patent Document 5 reported that a correlation was observed between a specific gene polymorphism ((CTG) n) in carnosine dipeptidase 1 gene and the onset of diabetic nephropathy. ing.

- Carnosine ⁇ dipeptidase 1 activity and protein levels were significantly lower in the group with the increase than in the group with no increase. This suggests that suppressing the action of carnosine dipeptidase 1 is likely to be effective in maintaining blood carnosine concentration.
- carnosine dipeptidase has various effects especially in the human body as a mammal, so the development of a technique that effectively inhibits this activity is very important.
- the phenanthroline shown above shows oral toxicity as a side effect while having enzyme inhibitory activity. Therefore, a composition that inhibits carnosine dipeptidase is strongly required to have high safety while effectively inhibiting its activity.

本発明の一態様は、ポリフェノールを含むカルノシンジペプチダーゼ阻害用組成物である。
本明細書において「ポリフェノール」とは、複数のフェノール性ヒドロキシ基(ベンゼン環、ナフタレン環などの芳香族炭化水素に結合したヒドロキシ基)を有する化合物を意味する。また、当該化合物の配糖体も、「ポリフェノール」に含まれる。
1-2-1.5環性トリテルペン酸
本発明ではまた、5環性トリテルペン酸をカルノシンジペプチダーゼ阻害用組成物に含有させることができる。5環性トリテルペン酸としては、特に限定されないが、例えば、ウルソール酸、マスリン酸、コロソリン酸、ベツリン酸、オレアノール酸等が挙げられる。本発明では、好ましくはウルソール酸が用いられる。
本発明ではまた、アンセリンをカルノシンジペプチダーゼ阻害用組成物に含有させることができる。アンセリン(anserine)は、哺乳動物の骨格筋及び脳、並びに鳥類に存在するジペプチドである。アンセリンはβ-アラニンと1-メチル-L-ヒスチジンとのペプチド結合によって形成されるジペプチドであることから、別称として、β-アラニル-N-メチルヒスチジン、又はβ-アラニル-1-N-メチルヒスチジンと称される。また、アンセリンのCAS登録番号は584-85-0である。
本明細書において「カルノシンジペプチダーゼ」とは、カルノシン(L-カルノシン)をβ-アラニンとヒスチジンとに分解することができるカルノシン分解酵素をいう。カルノシンジペプチダーゼ(カルノシン分解酵素)は、CNDP(carnosine dipeptidase)と省略して表すことができ、また、カルノシナーゼ又はカルノシダーゼとも称される。カルノシンジペプチダーゼには血清(型)カルノシン分解酵素であるcarnosine dipeptidase 1(CNDP1)と組織(型)カルノシン分解酵素であるcarnosine dipeptidase 2(CNDP2)とが含まれる。これらのうち、本発明で対象とされるカルノシンジペプチダーゼは、好ましくはcarnosine dipeptidase 1である。なお、carnosine dipeptidase 1及びcarnosine dipeptidase 2はともに、カルノシンのみならず、ヒスチジン残基をカルボキシル末端に有するあらゆるジペプチド(X-His(Xは天然アミノ酸)と表す)に対して分解活性を示すことが知られている。
上述した通り、カルノシンジペプチダーゼが阻害されることで、カルノシンジペプチダーゼにより分解されるカルノシンのヒト等の哺乳動物における体内濃度が維持、又は当該濃度の低下が抑制される。カルノシンの作用としては、プロトンバッファーリング活性、カルシウム分泌とカルシウム感受性制御、抗酸化作用、金属イオンキレート作用、ヒスチジン/ヒスタミンの細胞外供与体、高血糖改善作用、抗炎症作用、疲労回復促進作用、肌のシワ形成抑制作用、終末糖化産物の生成抑制、脳虚血による細胞死の抑制、アルツハイマー病(AD)モデルマウスにおけるアミロイドβの蓄積抑制作用、免疫調節作用等が挙げられる。そのため、カルノシンの体内濃度を高く保持することによって、統合失調症などに伴う認知機能低下やアルツハイマー、自閉症の予防又は改善効果が、高血糖改善作用に基づいて糖尿病又は酸化ストレス若しくは終末糖化産物の産生に起因する各種疾患発症の予防又は改善効果が、抗炎症作用に基づいて血管や組織の炎症の予防又は改善効果が、免疫調節作用に基づいて免疫機能低下の予防又は改善効果が期待できる。
本発明のカルノシンジペプチダーゼ阻害用組成物は、その形態に応じて、上記成分の他に、任意の添加剤や通常用いられる任意の成分を含有することができる。これらの添加剤及び/又は成分の例としては、ビタミンE、ビタミンC等のビタミン類、ミネラル類、栄養成分、香料などの生理活性成分の他、製剤化において配合される賦形剤、結合剤、乳化剤、緊張化剤(等張化剤)、緩衝剤、溶解補助剤、防腐剤、安定化剤、抗酸化剤、着色剤、凝固剤、又はコーティング剤等が挙げられるが、これらに限定されるものではない。
本発明のカルノシンジペプチダーゼ阻害用組成物は、前述のポリフェノール等を含有することを特徴としており、当該成分がカルノシンジペプチダーゼの活性を阻害して、カルノシンジペプチダーゼにより分解されるカルノシン体内濃度の維持、又は当該濃度の低下抑制が期待される。体内においてカルノシンが高い濃度で保持されることで、認知機能低下、糖尿病、疲労、肌のシワ形成、免疫機能低下、血管若しくは組織の炎症、酸化ストレス若しくは終末糖化産物の産生に起因する各種疾患、アルツハイマー、又は自閉症の予防又は改善を効果的に行うことができる。従って、本発明の組成物は、認知機能低下、糖尿病、疲労、肌のシワ形成、免疫機能低下、血管若しくは組織の炎症、酸化ストレス若しくは終末糖化産物の産生に起因する各種疾患、アルツハイマー、又は自閉症の予防又は改善用のカルノシンジペプチダーゼ阻害用組成物である。これらの用途に基づき、本発明のカルノシンジペプチダーゼ阻害用組成物は、認知機能低下、糖尿病、疲労、肌のシワ形成、免疫機能低下、血管若しくは組織の炎症、酸化ストレス若しくは終末糖化産物の産生に起因する各種疾患、アルツハイマー、又は自閉症の予防又は改善用組成物ともなり得る。なお、本明細書において「予防又は改善」には、現在の状態をより良い状態にすることと現在の状態よりも悪い状態になることを防ぐこととの両方の概念が包含されることから、治療、回復、軽減、緩和等の用語もこれに含まれ得る。
上述したポリフェノール等の成分は、カルノシンと併用することができる。そのため本発明は、一つの態様として、上述したポリフェノール等の成分とカルノシンとを組み合わせてなる組成物(以下、「本発明の併用組成物」とも称する)を提供することができる。
