【発明の属する技術分野】
本発明は、米蛋白の蛋白質分解酵素分解物(又はその処理物)を含有するプロリルエンドペプチダーゼ阻害用経口摂取物に関する。
本発明の経口摂取物は、プロリルエンドペプチダーゼを阻害することができるので、特に最近増加傾向にある老人性痴呆症の予防及び治療に有効な医薬品又は機能性食品や、特定保健用食品、栄養剤、健康食品等の飲食品に利用することができる。
【0002】
【従来の技術】
高齢化社会を迎えた現代にとって老人医療の重要性が大きくクローズアップされている。その中でも痴呆症の予防や治療は、本人だけでなく家族や社会を含めた大きな問題となっている。痴呆症の代表的なものには脳血管性痴呆とアルツハイマー型痴呆があり、前者に比べ後者は原因が未だ完全には解明されていない。また、アルツハイマー型痴呆は健忘症とも言われ、短期間の記憶の消失以外には他の運動能力などにあまり障害が現れない為、介護に重い負担がかかり大きな問題となっている。それゆえ治療法の開発が急務となっている。バックグラウンドや発症機構は未だ不明な点も多いが、治療薬の開発は活発に行われつつあり、臨床試験にまで進んでいるものもある。
【0003】
プロリルエンドペプチダーゼ(以下、PEPということもある)(EC3.4.21.26)は、プロリンに特異性を持ち、そのカルボキシル基側でペプチドを切断するセリンプロテアーゼで、脳、睾丸、肝臓での活性が高いことが知られている(蛋白質核酸酵素、25、513−523、(1980)、蛋白質核酸酵素、29、127−133、(1984))。PEPは神経伝達物質サブスタンスPや記憶に関係していると考えられるTHR(甲状腺刺激ホルモン)およびバソプレッシンを分解することが知られている。バソプレッシンは腎臓での水分再吸収に働くペプチドホルモンであるが、脳内で学習、記憶の過程にも関与しており、このホルモンの分解不活性化がおこると健忘症が進行するという事実がある。また、痴呆症患者のバソプレッシン量は、正常人のそれより少ないことがわかっている(BIOINDUSTRY、4、788−796、(1987))。
【0004】
バソプレッシンは、PEPによって2つのペプチドに分解される。健康人では脳でのPEPが正常に働いているが、何らかの理由で調節機構がはずれるとバソプレッシンが必要以上に分解され、記憶保持に傷害が現れる。したがってこの酵素の活性を阻害し痴呆症の治療をめざす研究がなされている。例えば、プロリルプロリナール誘導体(蛋白質核酸酵素、29、127、(1984))、N−アシルピロリジン誘導体(特開昭61−37764、特開昭61−183297、特開昭61−238775、特開昭61−238799、特開昭62−114957)などがスクリーニングされている。しかし、これらは合成品のため安全性に問題があるし、また構造が類似であるため既に構造活性相関が明らかとなっている(ABC、55、37−43、(1991))。
【0005】
【発明が解決しようとする課題】
老人性痴呆症の予防及び治療のために、安全で新しい構造を持ったプロリルエンドペプチダーゼ阻害物質が求められており、本発明は、このような特に安全性の高いすぐれた新規PEP阻害物質を開発する目的でなされたものである。
【0006】
【課題を解決するための手段】
本発明は、上記目的を達成するためになされたものであって、本発明者らは、天然物質中に副作用の無いプロリルエンドペプチダーゼ阻害物質を鋭意検索した結果、米蛋白質の分解物中に本阻害物質の存在を認め、該物質がペプチドであることを見いだし本発明を完成した。また副産物を原料とすることから資源の有効利用ともなるものである。
【0007】
本発明のPEP阻害物質としては、米蛋白質又は米蛋白質含有物質を蛋白質分解酵素で処理して得られたものを使用する。米蛋白質としては、プロラミン、グルテリン、グロブリン、アルブミン、及び/又はプロテオース等が精製品はもとより粗製品も使用できる。また、米蛋白質含有物としては、こ(れら)の米蛋白質を含有する物質が広く使用され、例えば、玄米、白米、糠、米を原料とする醸造食品(清酒、味りん、味噌、醤油など)のほか、その副産物(糠、粕など)が使用される。
【0008】
米蛋白質(含有物質)は、次いで、蛋白質分解酵素で処理する。この分解処理は、所望するのであれば、酵素分解のほか、化学的分解、物理的分解といった既知の蛋白質分解法が適宜、単用又は併用される。酵素分解法は、マイルドな条件で行われるので生成ペプチドの変性が低い等の利点があり、ペプシン、トリプシン、キモトリプシン、フイシンといった動植物起源の蛋白質分解酵素のほか、微生物起源の蛋白質分解酵素を用いて処理すればよい。
【0009】
すなわち、米蛋白からのプロリルエンドペプチダーゼ阻害物質の分離精製は酸、アルカリ、または酵素により分解したものを、必要ならば抽出、濃縮したのち種々の吸着剤に対する吸着親和性の差、種々の溶剤に対する溶解性の差、分子篩効果による溶出速度の差などの通常分離精製に用いられる方法や、それらを適宜組み合わせておこなえばよい。この分離精製は米蛋白を原料とした方が効率はよいが、玄米、白米、糠をそのままを使用してももちろん可能である。ここでいう米蛋白は、溶媒分画法により蛋白質を抽出することや逆に蛋白質以外の澱粉などを酵素により分解することでも得られる。また、米を原料とする醸造食品(清酒、味りん、味噌、醤油など)の製造において発生する糠や粕などの副産物をそのまま、または上記の溶媒分画法を適用したものを蛋白源として利用できる。醸造食品の副産物の場合は、醸造中に蛋白質の分解が起きていることが考えられるので、新たな分解は必要無い場合もある。具体的には、加水分解の条件としては特に限定はされないが、プロリルエンドペプチダーゼ阻害活性を指標として決めればよい。
【0010】
本発明のPEP阻害物質は、米蛋白質(含有物質)を蛋白質分解酵素で分解して得たもの(又はその処理物)であって、その中にはペプチドが含有されている。例えば、酒粕のペプシン分解物を逆相クロマト処理を含む精製処理に付したところ、8〜10残基のペプチド(LLSPFWNINA、LSPFWNINA、SPFWNINA)が単離され、特に10残基のペプチドに高いPEP阻害活性が認められた。
【0011】
また、これらのペプチド又はそれらの混合物にまで単離精製しなくても、酒類をペプシンで分解可溶化したものも、高いPEP阻害活性を有していた。
【0012】
したがって、本発明のPEP阻害物質としては、米蛋白(含有物質)を蛋白質分解酵素で分解したもの(又はその処理物)が適宜使用でき、例えば酒粕分解物が使用できるほか、ペプチドも使用することができる。
【0013】
米蛋白の蛋白質分解酵素分解物は、これをそのまま使用するほか、その処理物(濃縮物、ペースト化物、乾燥物、又は希釈物等)もPEP阻害物質として使用することができる。
【0014】
本発明においては、こ(れら)のPEP阻害物質を有効成分として、PEP阻害用経口摂取物とするものである。本発明に係るPEP阻害用経口摂取物は、医薬品タイプとしてまた飲食品タイプとして使用することができる。
【0015】
本発明のPEP阻害物質は、後記する実施例からも明らかなように、卓越したPEP阻害活性を有し、しかも天然物由来であって安全であり、現にウィスター系マウス10匹を用いた10日間の急性毒性試験においても、酒粕分解物の場合、1000mg/kgの経口投与でも死亡例は認められず、高い安全性が確認された。
【0016】
飲食品タイプとして使用する場合には、本有効成分であるPEP阻害物質(その処理物)をそのまま、使用したり、他の食品ないし食品成分と併用したりして適宜常法にしたがって使用できる。本有効成分を用いる本発明に係る経口摂取物は、固体状(粉末、顆粒状その他)、ペースト状、液状ないし懸濁状のいずれでもよいが、甘味料、酸味料、ビタミン剤その他ドリンク剤製造に常用される各種成分を用いて、健康ドリンクに製剤化すると好適である。
この場合、使用量に格別の限定はなく、機能性食品、特定健康食品、栄養剤、健康食品として、適宜飲食に供することができ、しかも安全性が高いので長期間に亘って摂取することも可能である。
【0017】
医薬品タイプの組成物として使用する場合、本有効成分は、種々の形態で投与される。その投与形態としては例えば錠剤、カプセル剤、顆粒剤、散剤、シロップ剤等による経口投与をあげることができる。これらの各種製剤は、常法に従って主薬に賦形剤、結合剤、崩壊剤、滑沢剤、矯味矯臭剤、溶解補助剤、懸濁剤、コーティング剤などの医薬の製剤技術分野において通常使用しうる既知の補助剤を用いて製剤化することができる。その使用量は症状、年令、体重、投与方法および剤形等によって異なるが、通常は、成人に対して1回約0.1mg乃至1,000mgを投与することができる。
【0018】
本発明に係る有効成分は、天然起源であるため、上記したように毒性は全くないか又は極めて低く、卓越した安全性を示し、急性毒性は全く認められなかった。したがって飲食品タイプの組成物として使用する場合は、予防用、保健用、通常の飲食品として使用する場合のいずれにおいても、有効成分の使用量に格別の限定はないし、医薬として使用する場合も、患者に応じて上記範囲内で適宜使用すればよい。また、本有効成分は多量に服用しても格別の副作用は認められず、きわめて安全である。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an oral ingestion for prolyl endopeptidase inhibition, which contains a proteolytic enzyme hydrolyzate of rice protein (or a processed product thereof).
Since the oral ingestion of the present invention can inhibit prolyl endopeptidase, it is particularly effective for preventing and treating senile dementia, which has recently been on the increase, in medicines or functional foods, foods for specified health use, and nutrition. It can be used for foods and drinks such as preparations and health foods.
[0002]
[Prior art]
The importance of geriatric care is greatly highlighted in the aging society. Above all, prevention and treatment of dementia has become a major problem not only for the individual but also for the family and society. Representative examples of dementia include cerebrovascular dementia and Alzheimer's dementia, and the cause of the latter has not been completely elucidated compared to the former. In addition, Alzheimer's dementia is also called amnesia, and since there is not much impairment in other motor skills other than the loss of short-term memory, a heavy burden is placed on nursing care, which is a major problem. Therefore, the development of treatments is urgently needed. Although the background and mechanism of onset are still unknown, therapeutic drugs are being actively developed, and some are progressing to clinical trials.
[0003]
Prolyl endopeptidase (hereinafter also referred to as PEP) (EC 3.4.21.26) is a serine protease that has specificity for proline and cleaves the peptide at the carboxyl side thereof, and is used in the brain, testis and liver. Is known to have high activity (protein nucleic acid enzyme, 25, 513-523, (1980), protein nucleic acid enzyme, 29, 127-133, (1984)). PEP is known to degrade neurotransmitter substance P and THR (thyroid stimulating hormone) and vasopressin, which are thought to be involved in memory. Vasopressin is a peptide hormone that works for reabsorption of water in the kidney, but is also involved in learning and memory processes in the brain, and there is a fact that when this hormone is degraded and inactivated, amnesia progresses . In addition, it is known that the amount of vasopressin in a dementia patient is smaller than that in a normal person (BIOINDUSTRY, 4, 788-796, (1987)).
[0004]
Vasopressin is degraded by PEP into two peptides. In healthy people, PEP in the brain works normally, but if the regulatory mechanism is lost for some reason, vasopressin is degraded more than necessary, causing damage to memory retention. Accordingly, studies have been made to inhibit the activity of this enzyme and to treat dementia. For example, prolyl prolinal derivatives (protein nucleic acid enzyme, 29, 127, (1984)), N-acylpyrrolidine derivatives (JP-A-61-37764, JP-A-61-183297, JP-A-61-238775, and JP-A-61-238775) 61-238799, JP-A-62-114957) and the like. However, since these are synthetic products, there is a problem in safety, and since their structures are similar, a structure-activity relationship has already been clarified (ABC, 55, 37-43, (1991)).
[0005]
[Problems to be solved by the invention]
For the prevention and treatment of senile dementia, a prolyl endopeptidase inhibitor having a safe and new structure is required, and the present invention relates to such a novel PEP inhibitor having a particularly high safety. It was made for development purposes.
[0006]
[Means for Solving the Problems]
The present invention has been made to achieve the above object, and the present inventors have conducted extensive searches for a prolyl endopeptidase inhibitor having no side effects in a natural substance, and as a result, it has found that The existence of this inhibitor was recognized, and it was found that the substance was a peptide, thus completing the present invention. Since by-products are used as raw materials, resources can be effectively used.
[0007]
As the PEP inhibitor of the present invention, a substance obtained by treating rice protein or a substance containing rice protein with a protease is used. As the rice protein, not only purified products such as prolamin, glutelin, globulin, albumin, and / or proteose but also crude products can be used. In addition, as the rice protein-containing material, a substance containing the rice protein of the present (rare) is widely used. For example, brown rice, polished rice, bran, brewed food made from rice (sake, taste phosphorus, miso, soy sauce) And its by-products (such as bran and lees).
[0008]
The rice protein (substance) is then treated with a proteolytic enzyme. For this decomposition treatment, if desired, known protein decomposition methods such as chemical decomposition and physical decomposition may be used alone or in combination, as appropriate, in addition to enzymatic decomposition. The enzymatic degradation method has advantages such as low denaturation of the produced peptide because it is carried out under mild conditions.It uses proteases of animal and plant origin such as pepsin, trypsin, chymotrypsin and fusin, as well as microbial proteases. It should be processed.
[0009]
In other words, the separation and purification of prolyl endopeptidase inhibitor from rice protein is carried out by extracting the acid, alkali, or enzyme-decomposed substance, if necessary, extracting and concentrating it, and then differences in adsorption affinity for various adsorbents and various solvents. It is sufficient to carry out a method usually used for separation and purification, such as a difference in solubility with respect to water, a difference in elution rate due to a molecular sieve effect, or a combination thereof. This separation and purification is more efficient when rice protein is used as a raw material, but of course brown rice, white rice and bran can be used as they are. The rice protein referred to here can be obtained by extracting the protein by a solvent fractionation method or conversely by decomposing starch and the like other than the protein with an enzyme. In addition, by-products such as bran and lees generated in the production of rice-based brewed foods (sake, miso phosphorus, miso, soy sauce, etc.) can be used as they are, or those to which the above-mentioned solvent fractionation method has been applied can be used as a protein source. it can. In the case of brewed food by-products, it is possible that protein degradation has occurred during brewing, so new degradation may not be necessary. Specifically, conditions for the hydrolysis are not particularly limited, but may be determined using prolyl endopeptidase inhibitory activity as an index.
[0010]
The PEP inhibitor of the present invention is obtained by degrading rice protein (containing substance) with a proteolytic enzyme (or a processed product thereof) and contains a peptide. For example, when a pepsin degradation product of sake lees was subjected to purification treatment including reverse phase chromatography, peptides having 8 to 10 residues (LLSPFWNINA, LSPFWNINA, SPFWNINA) were isolated. Activity was observed.
[0011]
Even if these peptides or mixtures thereof were not isolated and purified, alcoholic beverages obtained by decomposing and solubilizing with pepsin also had high PEP inhibitory activity.
[0012]
Therefore, as the PEP inhibitor of the present invention, a substance obtained by degrading rice protein (containing substance) with a protease (or a processed product thereof) can be used as appropriate. For example, a peptide derived from sake lees can be used in addition to the peptide. Can be.
[0013]
The proteolytic enzyme hydrolyzate of rice protein can be used as it is, or its processed product (concentrate, paste, dried product, diluted product, etc.) can be used as a PEP inhibitor.
[0014]
In the present invention, the PEP inhibitor is used as an active ingredient to provide an oral ingestion for PEP inhibition. The oral ingestion for PEP inhibition according to the present invention can be used as a pharmaceutical type and a food and drink type.
[0015]
As is clear from the examples described below, the PEP inhibitor of the present invention has excellent PEP inhibitory activity, is derived from a natural product, is safe, and actually uses 10 Wistar mice for 10 days. Also in the acute toxicity test of No. 1, in the case of the sake cake decomposition product, no death was observed even with oral administration of 1000 mg / kg, and high safety was confirmed.
[0016]
When used as a food or drink type, the PEP inhibitor (the processed product thereof), which is the present active ingredient, can be used as it is or in combination with other foods or food components, and can be used in accordance with a conventional method as appropriate. The oral ingestion according to the present invention using the present active ingredient may be in the form of solid (powder, granule or the like), paste, liquid or suspension. It is preferable to formulate into a health drink using various components commonly used in the art.
In this case, the amount of use is not particularly limited, and can be appropriately provided for eating and drinking as a functional food, a specific health food, a nutrient, and a health food, and can be taken for a long period of time because of its high safety. It is possible.
[0017]
When used as a pharmaceutical type composition, the active ingredient is administered in various forms. Examples of the administration form include oral administration by tablets, capsules, granules, powders, syrups and the like. These various preparations are commonly used in the field of pharmaceutical preparations such as excipients, binders, disintegrants, lubricants, flavoring agents, solubilizing agents, suspending agents, coating agents, and the like, in accordance with the conventional method. It can be formulated using known adjuvants. The amount used varies depending on symptoms, age, body weight, administration method, dosage form, etc., but usually about 0.1 mg to 1,000 mg can be administered to an adult once.
[0018]
Since the active ingredient according to the present invention is of natural origin, it has no or very low toxicity as described above, has excellent safety, and has not shown any acute toxicity. Therefore, when used as a food or drink type composition, for preventive use, for health, or in any of the cases where it is used as a normal food or drink, there is no particular limitation on the amount of the active ingredient used, and even when used as a medicine. It may be appropriately used within the above range depending on the patient. Also, even if the active ingredient is taken in a large amount, no particular side effects are observed, and it is extremely safe.
