Description

本発明は、L−テアニンを有効成分とするアセトアルデヒドの毒性抑制剤に関し、さらに詳しくは、アルコール飲料摂取に伴い血中に生じるアセトアルデヒドのもたらす毒性から生体を防御する薬剤に関する。   TECHNICAL FIELD The present invention relates to an acetaldehyde toxicity inhibitor containing L-theanine as an active ingredient, and more particularly, to an agent that protects a living body from toxicity caused by acetaldehyde generated in blood in association with ingestion of alcoholic beverages.

従来の技術Conventional technology

アルコール、特にエチルアルコールは主に肝臓でアルコール脱水素酵素によって酸化され、アセトアルデヒドに変換される。また、その一部はミクロゾームのエタノール酸化系(microsomal ethanol oxidizing system:MEOS)やペルオキシゾームに存在するカタラーゼによってもアセトアルデヒドへと酸化される(L.J. Kricka and P.M.S. Cleark, Biochemistry of alcohol and alcoholism,Ellis Horwood Ltd., Chichester, 1979)。アセトアルデヒドは更にアルデヒド脱水素酵素により酢酸に変換される。肝臓に取り込まれたアルコールの約75%は酢酸として循環系に放出されることになる(Lundquist, E. et al., J. Clin.Invest., Vol.41, 955-961, 1962)。一般に飲酒後の健康人の血中アルコール濃度は0.01-0.1%である(Lundquist, E., The metabolism of alcohol, 1-52, Biological basis of alcoholism, Wiley-interscience, Toronto, 1971)。一方、アセトアルデヒドの血中濃度はアルコールの 1/1000 程度である。   Alcohol, especially ethyl alcohol, is mainly oxidized in the liver by alcohol dehydrogenase and converted to acetaldehyde. Some of them are also oxidized to acetaldehyde by microsomal ethanol oxidizing system (MEOS) and catalase present in peroxisome (LJ Kricka and PMS Cleark, Biochemistry of alcohol and alcoholism, Ellis Horwood Ltd ., Chichester, 1979). Acetaldehyde is further converted to acetic acid by aldehyde dehydrogenase. About 75% of the alcohol taken up by the liver will be released into the circulation as acetic acid (Lundquist, E. et al., J. Clin. Invest., Vol. 41, 955-961, 1962). In general, the blood alcohol concentration of healthy people after drinking is 0.01-0.1% (Lundquist, E., The metabolism of alcohol, 1-52, Biological basis of alcoholism, Wiley-interscience, Toronto, 1971). On the other hand, the blood concentration of acetaldehyde is about 1/1000 that of alcohol.

アセトアルデヒドは、アルコール代謝上不可避的な生成物であり、アルコール飲料を過度に摂取したときの急性中毒や、いわゆる“悪酔い”の主因を形成すると考えられているが、近年、飲酒に伴うアセトアルデヒドの下記のような副次的な作用についても明らかにされつつある。   Acetaldehyde is an inevitable product in alcohol metabolism, and is thought to form the main cause of acute poisoning and so-called "sickness sickness" when excessive consumption of alcoholic beverages. Secondary effects such as are being clarified.

従って、アルコール飲料を健康的に嗜むためには、アセトアルデヒドによる上記生体への不都合な作用を低下させ、好ましからざる副次的作用を防止することが望ましい。特に、日本人をはじめとするモンゴロイドでは、遺伝的にアルデヒド脱水素酵素(ALDH2)の欠損が約50%の人々に見られる。そして、この酵素の欠損者におけるアルコール摂取後の血中アセトアルデヒド濃度は、欠損していない人と比べ、著しく高い(約17倍)ことが指摘されている(Harada, S., Lancet, 11, 982, 1981)。このように、アセトアルデヒドの毒性を軽減することは、アルコール飲料を健康的に嗜むために是非必要とされている。   Therefore, in order to taste alcoholic beverages healthily, it is desirable to reduce the above-mentioned adverse effects of acetaldehyde on the living body and prevent undesirable side effects. In particular, in Mongoloids including Japanese people, about 50% of people are genetically deficient in aldehyde dehydrogenase (ALDH2). In addition, it has been pointed out that blood acetaldehyde concentration after alcohol ingestion in a person deficient in this enzyme is significantly higher (about 17 times) than that in a person without deficiency (Harada, S., Lancet, 11, 982). , 1981). Thus, reducing the toxicity of acetaldehyde is indispensable for healthy drinking of alcoholic beverages.

このような目的にかなう物質としては、これまでに、L−システイン、L−2−メチルチアゾリン−4−カルボン酸、チアミン塩酸(Sprince, H. et al., Agents and Actions. Vol.4/2, 125-130, 1974)、重亜硫酸ナトリウム、D−ペニシラミン(Nagasawa, H. T., et al., Life Sci., Vol.20, 187-194, 1977 )、ニコチンアミド(Eriksson, C. J. P., FEBS Lett., Vol.40, 317, 1974)などが報告されている。   Substances meeting such a purpose include L-cysteine, L-2-methylthiazoline-4-carboxylic acid, and thiamine hydrochloride (Sprince, H. et al., Agents and Actions. Vol. 4/2). , 125-130, 1974), sodium bisulfite, D-penicillamine (Nagasawa, HT, et al., Life Sci., Vol. 20, 187-194, 1977), nicotinamide (Eriksson, CJP, FEBS Lett., Vol.40, 317, 1974).

しかしながら、L−システイン、チアミン塩酸、D−ペニシラミンなどのSH基を有する化合物の有効性については、D−ペニシラミンが臨床的に許容される投与量域ではアセトアルデヒドの血中濃度になんら影響を及ぼさないことから否定的見解も出されている(Inoue, K. et al., Jpn. J. Alcohol & Drug Dependence, Vol.19(1), 74-82, 1984)。また、L−システインは比較的毒性があり、他のチオール化合物も本発明の目的とは別の薬理作用も併せ持つことから、理想的なアセトアルデヒドの毒性低下剤とは言い難い。

Alcohol & Drug Dependence, Vol.19(1), 74-82, 1984
However, regarding the effectiveness of compounds having an SH group such as L-cysteine, thiamine hydrochloride, and D-penicillamine, D-penicillamine has no effect on the blood concentration of acetaldehyde in the clinically acceptable dose range. This has led to a negative opinion (Inoue, K. et al., Jpn. J. Alcohol & Drug Dependence, Vol. 19 (1), 74-82, 1984). In addition, L-cysteine is relatively toxic, and other thiol compounds also have a different pharmacological action from the object of the present invention. Therefore, it is hard to say that L-cysteine is an ideal acetaldehyde toxicity reducing agent.

このような現状に鑑み、アルコール摂取に伴って生成する血中アセトアルデヒドの作用を中和あるいは抑制し、アセトアルデヒドによって惹起される悪酔い症状を抑制することができる、真に有効な悪酔い防止剤が望まれてきた。   In view of such a current situation, a truly effective sickness inhibitor that can neutralize or suppress the action of blood acetaldehyde produced with alcohol intake and suppress the sickness symptoms caused by acetaldehyde is desired. Have been.

本発明者らは、このようなアセトアルデヒドの急性毒性を有効に抑制する物質を、マウスにアセトアルデヒドを投与した時の急性毒性の軽減を指標に、鋭意スクリーニングを行い、アミノ酸の一つであるL−α−アラニンがアセトアルデヒドの急性毒性を有効に抑制することを見出し、特許出願を行った(特開昭59−255252号公報参照)。   The present inventors have conducted intensive screening of such a substance that effectively suppresses the acute toxicity of acetaldehyde, using as an index the reduction of acute toxicity when acetaldehyde is administered to mice, and found that one of the amino acids L- They found that α-alanine effectively suppressed the acute toxicity of acetaldehyde, and filed a patent application (see JP-A-59-255252).

本発明者らは、さらに有効なアセトアルデヒドの急性毒性抑制剤を見出すべく、マウスに致死量のアセトアルデヒドを投与した時の救命率を指標に、鋭意スクリーニングを行った結果、L−テアニンが血中アセトアルデヒドの毒性から生体を極めて有効に防御することを見出し、これを有効成分とする組成物を製造して本発明を完成した。すなわち、本発明はL−テアニンを有効成分として含有し、アルコール急性毒性や悪酔いの予防、治療を目的とする悪酔い防止剤を提供するものである。   The present inventors have conducted intensive screening with the index of the survival rate when a lethal dose of acetaldehyde was administered to mice as an index to find a more effective acute toxicity inhibitor of acetaldehyde. The present inventors have found that the living body is very effectively protected from the toxicity of, and produced a composition containing the same as an active ingredient, thereby completing the present invention. That is, the present invention provides an agent for preventing sickness that contains L-theanine as an active ingredient and aims to prevent and treat acute alcohol toxicity and sickness.

本発明に使用するL−テアニン(L-Glutamic acid-γ-monoethylamide)は、茶の葉に含まれているグルタミン酸誘導体で、旨味の主成分である。茶の葉中のその含有量は、他のアミノ酸よりも高く、玉露(上)で 2466 mg%、玉露(並)で 2007 mg%、煎茶(上)で 1496mg %、煎茶(並)で 652 mg %と報告されている(茶研報 No.40, 65, 1973)。また、呈味を用途とする食品添加物として使用されており、その使用基準は制限されていない。   L-Theanine (L-Glutamic acid-γ-monoethylamide) used in the present invention is a glutamic acid derivative contained in tea leaves and is a main component of umami. Its content in tea leaves is higher than other amino acids, 2466 mg% for Gyokuro (upper), 2007 mg% for Gyokuro (upper), 1496 mg% for Sencha (upper), and 652 mg for Sencha (upper) % (Chakenho No.40, 65, 1973). In addition, it is used as a food additive for taste purposes, and its use standards are not limited.

また、L−テアニンの薬理作用としては、マウスを用いた実験において、カフェインによって誘発されるけいれん死や運動量の増加に対して拮抗することが報告されており(Chem. Pharm. Bull. Vol.19, 1257-1261, 1971, 薬学雑誌, Vol.95, 892-895, 1975)、L−テアニンはお茶に含まれるカフェインの作用を穏やにするものと考えられているが、L−テアニンがアセトアルデヒドの毒性を軽減するとの報告はない。   In addition, as a pharmacological action of L-theanine, it has been reported in an experiment using mice that it antagonizes caffeine-induced seizures and increases in locomotor activity (Chem. Pharm. Bull. Vol. 19, 1257-1261, 1971, Pharmaceutical Magazine, Vol. 95, 892-895, 1975), L-theanine is thought to moderate the action of caffeine contained in tea. Has not been reported to reduce the toxicity of acetaldehyde.

本発明の毒性抑制剤の有効成分であるL−テアニンは、薬学的に許容されうる塩、たとえば塩酸塩の形で、賦形剤、担体等の薬品及び食品分野で慣用の補助成分、たとえば乳糖、ショ糖、液糖、蜂蜜、ステアリン酸マグネシウム、オキシプロピルセルロース、各種ビタミン類、クエン酸、リンゴ酸、香料、無機塩などとともに、カプセル剤、錠剤、粉末剤、顆粒剤、ドリンク剤、注射剤、点滴剤等に製剤することができる。更に、アルコール飲料やミネラルウォーターに用時添加する易溶性製剤としてもよい。   L-theanine, which is an active ingredient of the toxicity inhibitor of the present invention, is a pharmaceutically acceptable salt such as a hydrochloride in the form of an excipient, a carrier such as a carrier, and an auxiliary ingredient commonly used in the field of medicine and food, such as lactose. , Sucrose, liquid sugar, honey, magnesium stearate, oxypropylcellulose, various vitamins, citric acid, malic acid, flavors, inorganic salts, etc., capsules, tablets, powders, granules, drinks, injections , Can be formulated into drops and the like. Further, it may be a readily soluble preparation to be added to an alcoholic beverage or mineral water when used.

ドリンク剤の場合、必要に応じ、他の生理活性成分、ミネラル、ビタミン、ホルモン、栄養成分、香味剤等を混合することにより、嗜好飲料的性格を持たせることも可能である。   In the case of drinks, if desired, other physiologically active ingredients, minerals, vitamins, hormones, nutrients, flavoring agents, and the like can be mixed to impart a taste-like beverage character.

L−テアニンは、マウスを用いた急性毒性試験において、2 g/kg 経口投与で死亡例はなく、一般症状及び体重等に異常は認められず、非常に弱毒または無害の物質である。   L-theanine is a very attenuated or harmless substance in an acute toxicity test using mice, with no deaths due to oral administration of 2 g / kg, no abnormality in general symptoms, body weight, etc., observed.

本発明のL−テアニンを二日酔いまたは悪酔いの予防または治療剤として用いるには、後述の実施例の、マウスに致死量のアセトアルデヒドを投与した時にL−テアニンが示す毒性軽減効果と、実際のヒトの悪酔い時の平均的な血中のアセトアルデヒド濃度(約 20μmol/l )および経口投与の場合の吸収率等を考慮して、L−テアニンとして、0.3 mg/kg 以上を投与すればよい。L−テアニンの投与量に特に上限は存在しないが、L−テアニンの特有の呈味と経済性を考慮すると、一般に300 mg/kg 程度を超えないことが好ましい。従って、本発明の悪酔い防止剤がその効果を十分に発揮させるためには、L−テアニンを1回服用当り 0.02 〜2 g 含有することが好ましい。本発明の悪酔い防止剤は、アルコール飲料の摂取前、摂取中または摂取後に服用し、アセトアルデヒドによる悪酔いの予防または治療をすることができる。   In order to use the L-theanine of the present invention as a preventive or therapeutic agent for hangover or sickness, the toxicity-reducing effect exhibited by L-theanine when a lethal dose of acetaldehyde is administered to a mouse, as described in Examples described below, and the effect of a real human Considering the average blood acetaldehyde concentration (about 20 μmol / l) at the time of sickness and the absorption rate in the case of oral administration, 0.3 mg / kg or more may be administered as L-theanine. Although there is no particular upper limit to the dose of L-theanine, it is generally preferable that the dose does not exceed about 300 mg / kg in view of the unique taste and economy of L-theanine. Therefore, in order for the agent for preventing sickness of the present invention to exert its effect sufficiently, it is preferable to contain 0.02 to 2 g of L-theanine per dose. The sickness-preventing agent of the present invention can be taken before, during, or after ingesting an alcoholic beverage to prevent or treat sickness caused by acetaldehyde.

本発明に用いたL−テアニンは、後述の実施例から明らかなように、マウスに致死量のアセトアルデヒド(11 mmol/kg)を投与した場合の生存率を改善する。また本発明のドリンク剤は、後述の評価例に示すように、悪酔いし易いとされるアセトアルデヒド脱水酵素欠損型パネラーにおいて、悪酔いを予防する。   L-theanine used in the present invention improves the survival rate when a lethal dose of acetaldehyde (11 mmol / kg) is administered to mice, as will be apparent from the examples described later. In addition, the drink preparation of the present invention prevents sickness in acetaldehyde dehydratase deficient panelers, which are considered to be easily sick, as shown in evaluation examples described later.

L−テアニンがどの様にしてアセトアルデヒドの毒性を抑制するのかは未だ詳らかではないが、アセトアルデヒドの生理作用として、副腎髄質や交感神経を刺激して、カテコールアミンの遊離を促進し、心臓のβ−受容体を介して心拍数を上昇させることが判明しているので、動物にアセトアルデヒドを大量に投与するとこの作用が強くなり、不整脈を引き起こし、死に至ると考えられている。よって、L−テアニンのアセトアルデヒド毒性抑制の機序は、アセトアルデヒドにより遊離が促進されるカテコールアミンの作用に拮抗するためと考えられる。   It is not yet clear how L-theanine suppresses the toxicity of acetaldehyde, but as a physiological action of acetaldehyde, it stimulates the adrenal medulla and the sympathetic nerve, promotes the release of catecholamines, and stimulates the cardiac β-receptor. Since it has been shown to increase heart rate through the body, it is believed that administration of large doses of acetaldehyde to animals enhances this effect, causing arrhythmias and death. Therefore, it is considered that the mechanism of the inhibition of acetaldehyde toxicity of L-theanine is to antagonize the action of catecholamine whose release is promoted by acetaldehyde.

次に実施例によって本発明をさらに説明するが、本発明の範囲はこれらのみに限定されるものではない。   Next, the present invention will be further described with reference to Examples, but the scope of the present invention is not limited only to these.

Solid feed CE-2 (CLEA Japan) and drinking water were allowed ad libitum.

アセトアルデヒドは蒸留水にて希釈し、投与量が11ミリモル/kgになる様に調整した。また、L−テアニンは投与量が 0. 2 および 2 g/kg になるように蒸留水に溶解して試験に供した。すべての注射量は 10 ml/kg とした。   Acetaldehyde was diluted with distilled water and adjusted to a dose of 11 mmol / kg. In addition, L-theanine was dissolved in distilled water so that the dose became 0.2 and 2 g / kg, and used for the test. All injection volumes were 10 ml / kg.

マウスは1群12匹とし、規定量のL−テアニンまたはコントロールとして蒸留水を腹腔内投与し、30分後にアセトアルデヒドを腹腔内投与した。
アセトアルデヒド投与2時間後及び2週間後の生存率を観察し、χ2 検定により有意差を判定した。
Each group consisted of 12 mice, and a prescribed amount of L-theanine or distilled water as a control was intraperitoneally administered, and 30 minutes later, acetaldehyde was intraperitoneally administered.
Observing the acetaldehyde administered 2 hours and survival rate after 2 weeks, it was determined significant differences by chi 2 test.

結果は〔表1〕に示すように、コントロール群の2時間後および2週間後の生存率がそれぞれ16.7%であったのに対して、L−テアニン 0.2 g/kg 投与群の生存率はそれぞれ33.3%、25.0%また 2 g/kg 投与群の生存率はそれぞれ66.7%、58.3%であり、 2 g/kg 投与群ではコントロール群に較べて危険率5%以下で有意であった。   As shown in [Table 1], the survival rate of the control group at 2 hours and 2 weeks was 16.7%, respectively, whereas the survival rate of the L-theanine 0.2 g / kg administration group was 26.7%. The survival rates of the 33.3%, 25.0%, and 2 g / kg groups were 66.7% and 58.3%, respectively, and the 2 g / kg group was significantly lower than the control group with a risk rate of 5% or less.
