Description

本発明は植物の抽出物又はその成分を有効成分とし、グリケーションにより生じる各種組織障害の予防及び治療・改善効果を有する、安全性の高いグリケーション阻害剤及びその利用に関する。   The present invention relates to a highly safe glycation inhibitor having a plant extract or a component thereof as an active ingredient, having an effect of preventing, treating and improving various tissue disorders caused by glycation, and a use thereof.

近年、環境条件の悪化や生活様式の変化、社会生活の複雑化に伴うストレスの増加等により、老化が促進される要因が増えている。しかし一方で、日本人の平均寿命が延び、高齢者の占める割合が増えるとともに、若々しく健康に暮らすことの大切さが見直されてきている。従って、老化の進行を抑制することは、万人の待ち望んでいるところでもある。   In recent years, factors that promote aging are increasing due to deterioration in environmental conditions, changes in lifestyles, and an increase in stress accompanying the complication of social life. On the other hand, however, the average life expectancy of Japanese people has increased and the proportion of elderly people has increased, and the importance of living young and healthy has been reconsidered. Therefore, suppressing the progress of aging is something everyone is waiting for.

老化の進行には様々な要因が関与しているが、その要因の1つに非酵素的蛋白糖化反応が挙げられている。これは、還元糖とアミノ酸又は蛋白質の結合により、蛋白質本来の機能に障害をもたらす反応であり、グリケーション(褐変反応)と呼ばれている。生体内の種々の生理機能は蛋白質が司っており、糖化された蛋白は本来の機能を発揮できず、各種の機能障害をもたらすと考えられる。このグリケーションの初期段階反応物質は、アマドリ化合物と呼ばれる蛋白質と糖の結合物であり、更にこの反応は、脱水、重合を経て蛍光性、褐色化、分子内及び分子間架橋形成を特徴とする終末糖化物質(advanced glycation end products: AGE)になる。   Various factors are involved in the progress of aging, and one of the factors is a non-enzymatic protein saccharification reaction. This is a reaction in which the intrinsic function of the protein is impaired due to the binding of the reducing sugar and the amino acid or protein, and is called glycation (browning reaction). Various physiological functions in the living body are controlled by proteins, and glycated proteins cannot exert their original functions and are thought to cause various functional disorders. The early stage reactant of this glycation is a protein-sugar conjugate called an Amadori compound, and this reaction is characterized by dehydration, polymerization, fluorescence, browning, intra- and intermolecular cross-link formation. It becomes advanced glycation end products (AGE).

これらAGEは、加齢とともに生体内に蓄積し、加齢で認められる種々の組織障害、例えば、皮膚、血管壁、関節、肺等の結合組織の硬化(例えば、非特許文献1〜4参照)に関連することが示唆されており、皮膚の肥厚やしわの形成、動脈硬化、関節炎、心肺機能低下等の原因になると考えられている。また、白内障(例えば、非特許文献5参照)にも関連していると考えられている。また、グリケーションは加齢による組織障害の原因となるだけではなく、日光性弾力繊維症、アルツハイマー病、糖尿病合併症等の疾病に関与することが推測されている。例えば、日光性弾力線維症の皮膚組織にはAGEの一種であるカルボキシメチルリジン(CML)が検出されており、CMLの蓄積が深いしわや皮膚組織の硬化等の病変に関わっていることが示唆されている(例えば、非特許文献6参照)。また、アルツハイマー病におけるβ-アミロイドペプチドの脳内蓄積にAGEが関与していることが示唆されている(例えば、非特許文献7参照)。   These AGEs accumulate in the living body with aging, and various tissue disorders observed at aging, for example, hardening of connective tissues such as skin, blood vessel walls, joints, and lungs (for example, see Non-Patent Documents 1 to 4) It is thought to cause skin thickening and wrinkle formation, arteriosclerosis, arthritis, cardiopulmonary dysfunction and the like. It is also considered to be related to cataracts (for example, see Non-Patent Document 5). Glycation not only causes tissue damage due to aging, but is also presumed to be involved in diseases such as solar elastic fibrosis, Alzheimer's disease, and diabetic complications. For example, carboxymethyl lysine (CML), a type of AGE, has been detected in skin tissue with solar elastic fibrosis, suggesting that the accumulation of CML is involved in lesions such as deep wrinkles and hardening of skin tissue. (For example, see Non-Patent Document 6). Further, it has been suggested that AGE is involved in the accumulation of β-amyloid peptide in the brain in Alzheimer's disease (for example, see Non-Patent Document 7).

更に、糖尿病における腎障害、網膜症にAGEの蓄積が関係していることも示唆されている(例えば、非特許文献8参照)。このようなAGEの蓄積に対し、その元となるグリケーションを阻害する薬剤としてアミノグアニジンが知られている。この化合物は、糖尿病合併症である網膜症、腎障害、神経障害に有効であることがモデル動物で確認されており(例えば、非特許文献9参照)、糖尿病合併症の治療薬として米国で治験が進められている。しかし、アミノグアニジン服用により頭痛、悪心等の副作用が報告されており、医師の指導のもとに服用する必要がある。   Furthermore, it has been suggested that AGE accumulation is related to renal disorder and retinopathy in diabetes (for example, see Non-Patent Document 8). Aminoguanidine is known as a drug that inhibits glycation as a source of such AGE accumulation. This compound has been confirmed to be effective in diabetic complications such as retinopathy, renal disorder and neuropathy in model animals (for example, see Non-Patent Document 9), and is studied in the United States as a therapeutic agent for diabetic complications. Is being promoted. However, side effects such as headache and nausea have been reported by taking aminoguanidine, and it is necessary to take it under the guidance of a doctor.

The extraction conditions are not particularly limited. For example, various parts of the plant (whole plant, flower, calyx, seed, fruit, leaf, branch, bark, root bark, rhizome, root, etc.) can be used as they are or cut, crushed or It is manufactured by finely pulverizing, extracting or extracting with a solvent.

このうち、溶媒を用いた抽出は、一般に使用する溶媒に合わせて常圧〜加圧下で常温〜溶媒の沸点の温度条件下で10分〜1週間程度行えばよい。抽出に使用する溶媒としては、植物種や処理工程にあわせて通常用いられる溶媒を適宜選択して用いればよく、例えば、水やアルコール類(例えば、メタノール、無水エタノール、エタノール等の低級アルコール、又はプロピレングリコール、1,3−ブチレングリコール等の多価アルコール)、アセトン等のケトン類、ジエチルエーテル、ジオキサン、アセトニトリル、酢酸エチルエステル等のエステル類又はキシレン、ベンゼン、クロロホルム等の有機溶媒が挙げられる。なお、食品や化粧品素材として用いる場合等、有機溶媒が残留が好ましくない場合は、特に水やエタノール等を選択することが好ましい。これらの溶媒は単独で用いることもできるが、2種類以上を任意に組み合わせて使用することもできる。   Among these, extraction using a solvent may be performed for about 10 minutes to 1 week under a temperature condition of normal pressure to normal pressure and normal temperature to the boiling point of the solvent in accordance with a generally used solvent. As the solvent used for the extraction, a solvent usually used in accordance with the plant species and the treatment step may be appropriately selected and used, for example, water and alcohols (eg, methanol, anhydrous ethanol, lower alcohols such as ethanol, or Polyhydric alcohols such as propylene glycol and 1,3-butylene glycol); ketones such as acetone; esters such as diethyl ether, dioxane, acetonitrile and ethyl acetate; and organic solvents such as xylene, benzene and chloroform. In addition, when the organic solvent is not preferable, such as when using as a food or cosmetic material, it is particularly preferable to select water, ethanol, or the like. These solvents can be used alone or in combination of two or more.

具体的には、例えば以下の方法が使用できる。すなわち、植物原体あるいは乾燥物を細砕し、抽出溶媒を5〜20倍量加え、常圧下、室温で1週間程度静置、又は抽出溶媒の沸点付近で10〜30分程抽出してから濾過して得られた濾液を減圧乾固あるいは凍結乾燥して植物抽出物を得る。   Specifically, for example, the following method can be used. That is, the plant body or the dried product is pulverized, the extraction solvent is added in an amount of 5 to 20 times, and the mixture is allowed to stand at room temperature under normal pressure for about one week, or extracted at about the boiling point of the extraction solvent for about 10 to 30 minutes. The filtrate obtained by filtration is dried under reduced pressure or freeze-dried to obtain a plant extract.

上記のようにして得られた植物の抽出物はそのままの状態で使用することもできるが、必要に応じ、その効力に影響のない範囲で更に脱臭、脱色等の精製処理を加えても良い。このような精製処理としては、通常の手段を任意に選択して行えば良く、例えば濾過又はイオン交換樹脂や活性炭カラム等を用い、吸着・脱色・精製等を行なえば良い。更に、凍結乾燥又は濃縮処理等により溶液状、ペースト状、ゲル状、又は粉末状の精製物を得ることができる。   The plant extract obtained as described above can be used as it is, but if necessary, a purification treatment such as deodorization and decolorization may be added as far as the effect is not affected. Such a purification treatment may be performed by arbitrarily selecting a usual means. For example, filtration, ion exchange resin, activated carbon column, or the like may be used to perform adsorption, decolorization, purification, or the like.

Test example 1
Measurement of glycation inhibitory activity of plant hot water extract:
The early stage reactant of glycation is a protein-sugar conjugate called an Amadori compound. In addition, this early stage reactant undergoes dehydration and polymerization to form a fluorescent advanced saccharified substance (AGE). Therefore, the glycation inhibitory action can be measured by measuring the amount of AGE.

検体としては、製造例1で得られた植物熱水抽出物(実施品1〜111)を用い、AGE量の測定はナカザワらの方法(Nakazawa-H et al., J. Agric. Food Chem., 48, 180-185 (2000))を一部改変して行った。なお、既知のグリケーション阻害剤であるアミノグアニジンを本試験の陽性対照として用いた。   As the specimen, the plant hot water extract obtained in Production Example 1 (Examples 1-111) was used, and the amount of AGE was measured by the method of Nakazawa-H et al. (Nakazawa-H et al., J. Agric. Food Chem. , 48, 180-185 (2000)). In addition, aminoguanidine which is a known glycation inhibitor was used as a positive control in this test.

各検体は蒸留水で最終濃度10、2、0.4、0.08、0.016、0.0032mg/mLになるように調整し、スクリューキャップ付き試験管に500μLずつ分注後オートクレーブ滅菌して試料とした。また、陽性対照は、アミノグアニジンを蒸留水で200、100、50、25、12.5、6.25mMになるように調製し、これを滅菌済みの試験管にフィルター滅菌しながら500μLずつ分注して調製した。なお、対照には蒸留水を用いた。   Each sample was adjusted to a final concentration of 10, 2, 0.4, 0.08, 0.016, 0.0032 mg / mL with distilled water, dispensed 500 μL each into a test tube with a screw cap, and sterilized in an autoclave. To make a sample. As a positive control, aminoguanidine was prepared with distilled water to have a concentration of 200, 100, 50, 25, 12.5, and 6.25 mM, and this was dispensed into sterilized test tubes by filter-sterilizing 500 μL. Prepared. Note that distilled water was used as a control.

上記の検体、陽性対照および対照の各々の試験管にフィルター滅菌済みの40mg/mLの牛血清アルブミン(bovine serum albumin, fractionV; Sigma社製、以下、「BSA」という)、1MのD−フラクトース(最終濃度0.5M)を含有する400mMリン酸カリウム緩衝液(pH7.4、最終濃度200mM)を500μLずつ添加し、37℃で7日間遮光下で反応させた。ブランクとしては、D−フラクトースが入っていない試験管を用意した。   The test sample, the positive control, and the control were each sterilized with filter-sterilized 40 mg / mL bovine serum albumin (fraction V; manufactured by Sigma, hereinafter referred to as “BSA”) and 1M D-fructose ( 500 mM of a 400 mM potassium phosphate buffer solution (pH 7.4, final concentration: 200 mM) containing a final concentration of 0.5 M) was added thereto, and reacted at 37 ° C. for 7 days under light shielding. A test tube containing no D-fructose was prepared as a blank.

反応終了後、各試験管に10%トリクロロ酢酸溶液1mLを添加、攪拌し、冷却遠心(4℃、3,000rpm、5分)を行った後、上清をデカントで除去し、更に沈殿を5%トリクロロ酢酸溶液2mLで2回洗浄した。洗浄終了後、沈殿を200mMリン酸カリウム緩衝液(pH7.4)2mLに溶解した。溶解した沈殿物200μLを蛍光測定用96穴プレートに移し、蛍光プレートリーダーSPECTRAmax GEMINI XS(モレキュラーデバイス社)を用いて、励起波長350nm、蛍光波長425nmで蛍光を測定し、以下の数式1に従いグリケーション阻害率を算出した。   After the reaction was completed, 1 mL of a 10% trichloroacetic acid solution was added to each test tube, stirred, centrifuged at 4 ° C. (3,000 rpm, 5 minutes), the supernatant was decanted, and the precipitate was further removed. Washed twice with 2 mL of a% trichloroacetic acid solution. After the washing was completed, the precipitate was dissolved in 2 mL of a 200 mM potassium phosphate buffer (pH 7.4). 200 μL of the dissolved precipitate was transferred to a 96-well plate for fluorescence measurement, and the fluorescence was measured at an excitation wavelength of 350 nm and a fluorescence wavelength of 425 nm using a fluorescence plate reader SPECTRAmax GEMINI XS (Molecular Devices).
