Description

【発明の属する技術分野】
本発明は血管新生阻害剤に関する。より詳細には、担子菌類から得られるピログルタミン酸含有抽出物を有効成分として含有してなる血管新生阻害剤に関するものである。
【0002】
【従来の技術】
血管新生とは、動物の組織又は器官においてプロテアーゼにより血管の基底膜が分解、破壊され、血管内皮細胞が遊走して増殖し、細胞外マトリックスへ接着し、血管内皮細胞が分化して血管腔を形成することにより新しい血管脈が生成する現象をいう。一般に、幼児期や成長期には新たな血管が形成され伸長するが、成長期を過ぎると体内で血管新生が起こる場面は限定される。すなわち、血管新生は黄体形成、排卵、胚発生、胎盤形成等の通常の生理条件下で観察され、損傷の治癒、炎症の修復過程でも起こる。このように、血管新生は健常な状態で発生し、組織の回復に重要な役割を担っているが、糖尿病をはじめ多くの慢性疾患において毛細血管が増加して組織に重篤な損傷をもたらすことも知られている。
【0003】
血管新生が病因になり又は病態の悪化に関与している疾患として、悪性腫瘍の増大や転移、糖尿病性網膜症、血管新生緑内障、炎症性皮膚疾患、関節炎リウマチ、変形性関節症、粥状動脈硬化症、心筋梗塞等の閉塞性疾患等がある。
【0004】
例えば、悪性腫瘍が増殖する際には、腫瘍細胞の増殖に必要な栄養や酸素を得るために腫瘍細胞が自ら血管新生促進因子による血管の新生を誘導し、新生された血管を通して栄養分を得て腫瘍細胞はさらに増殖する。他の臓器や部位への転移も血管新生を誘導し、血流にのって腫瘍細胞が移動する。又、糖尿病性網膜症の場合には、糖尿病による粘性血液よって毛細血管が詰まり障害を受け、網膜に出血や浮腫を生じ、これが慢性化すると網膜は酸素や栄養の不足を起こすため、網膜上や神経系乳頭上に新生血管が発生し、その周囲に繊維組織が形成される。この繊維組織によって網膜が引張り上げられたり(網膜剥離)、網膜の血管が引き裂かれて出血を起こし(硝子体出血)、やがて高度視力障害や失明に至る。
【0005】
このように、血管新生は様々な疾病の発症や進行に深く関与しているため、これら疾病の治療と予防をねらいとして血管新生を抑制する物質の探索がこれまでに数多く行われ、現在も鋭意研究がすすめられている。血管新生を抑制する作用のある物質や薬剤として、硫酸化多糖体(例えば、特許文献1参照)、トラフェルミン、ヘパリン及びステロイド(例えば、特許文献2及び特許文献3参照)、アスコルビン酸エーテル及びこの関連化合物(例えば、特許文献4参照)、インターフェロンα又はインターフェロンβ(例えば、非特許文献1参照)、チアゾール誘導体(例えば、特許文献5参照)、鮫軟骨エキス(コンドロイチン及びムコ多糖類)(例えば、特許文献6参照)、ストレプトコッカス細菌由来のポリサッカライド(例えば、特許文献7参照)、O−置換フマギロール誘導体(例えば、特許文献8参照)、ネオアガロオリゴ糖(例えば、特許文献9参照)等が提案されている。
【0006】
しかしながら、これまで血管新生を阻害する作用を示す物質として提案、検討された物質は、その効果が実用的ではない投与条件下での実験結果に基づくものであったり、副作用の懸念があったり、あるいは利用形態において多量に摂取しなければならず、実用面まで考慮するといずれも十分に満足できる効果を発揮し得るものではなかった。このため、血管新生をより強力に阻害し、安全性の点でも懸念のない物質を開発することが求められている。

【発明が解決しようとする課題】
かかる現状に鑑み、本発明では、前記疾病の予防や治療に有効利用でき、血管新生を強力に抑制する新規な血管新生阻害剤を提供すること、又、これを産業上有効に活用できる態様の組成物として提供することを課題とした。
【0009】
【課題を解決するための手段】
本発明者らは、前記課題を解決するために、多数の植物原料及びそのエキス類と血管新生阻害作用との関連性について鋭意検討を行った結果、ピログルタミン酸類が本発明の所望の効果を顕著に奏することを見出し、本発明を完成するに至った。すなわち、本発明によれば、ピログルタミン酸類、望ましくはピログルタミン酸を含む担子菌類の抽出物を有効成分として含有してなる血管新生阻害剤が提供される。又、この血管新生阻害剤を配合してなる、血管新生の抑制、腫瘍の抑制、免疫の賦活等のための組成物、例えば、飲食品や医薬品が提供される。
【0010】
本発明の血管新生阻害剤において、有効成分とするピログルタミン酸(2−ピロリドン−5−カルボン酸)は光学異性体のL体又はDL体が好ましく、L体がより好ましい。又、ピログルタミン酸の誘導体は塩及び/又はアミドであることが好ましい。
【0011】
本発明に係るピログルタミン酸及び/又はその誘導体は、その態様として天然物、その抽出物又は化学的合成物を採用することができるが、とりわけ担子菌類の子実体又は菌糸体の抽出物又は精製物を用いるものがよい。ここで、担子菌類はいわゆる茸類であり、シイタケ、エノキタケ、シメジ、ヒラタケ、アガリクス茸、メシマコブ茸、霊芝、ヤマブシ茸、カワラタケ、ハラタケ、マイタケ、ハナビラタケ、スエヒロタケ、シロキクラゲ、冬虫夏草からなる群から選ばれる1種又は2種以上を用いることが望ましい。
【0012】
担子菌類の抽出物は、担子菌類から水で抽出し、次いで親水性有機溶媒を用いて抽出されたもの、あるいは、水及び/又は親水性有機溶媒と、疎水性有機溶媒とを用いて抽出されたものが望ましい。ここで、親水性有機溶媒はメタノール、エタノール、アセトン又はプロパノールがよく、疎水性有機溶媒はヘキサン又はクロロホルムが好ましい。
【0013】
本発明によって提供される前述の血管新生阻害剤を配合してなる組成物は、血管新生を抑制するためのものであり及び/又は免疫を賦活するためのものであり、その望ましい態様は飲食品又は医薬品である。
【0014】
【発明の実施の形態】
まず、本発明の血管新生阻害剤及びその製造方法について詳述する。本発明の血管新生阻害剤が必須成分として含有するピログルタミン酸及びその誘導体において、ピログルタミン酸(2−ピロリドン−5−カルボン酸)は、グルタミン酸が分子内脱水して環状化した構造を有するものであり、化学的合成法、酵素法、あるいは天然物からの加水分解処理や抽出処理等によって得ることができる。いずれの方法から調製するにしろグルタミン酸の部分はL−グルタミン酸、D−グルタミン酸又はDL−グルタミン酸の光学異性体を対象とすることができるが、本発明の効果の点からL−グルタミン酸又はDL−グルタミン酸が好適であり、更にはL−グルタミン酸が最も好ましい。
【0015】
ピログルタミン酸の誘導体としては塩及び/又はアミドが望ましい。この塩としてはナトリウム塩、カリウム塩、カルシウム塩、マグネシウム塩等を例示でき、このうちナトリウム塩がより好適である。又、本発明のピログルタミン酸誘導体はエステルを対象にすることもでき、水及び/又は親水性有機溶媒に可溶かつ疎水性有機溶媒に不溶の性状を示すものが望ましく、その態様としてメタノール、エタノール、n−プロパノール、イソプロパノール、ブタノール等の低級一価アルコール類、乳酸、リンゴ酸、酒石酸、クエン酸、グルコン酸等のヒドロキシ有機酸類、エチレングリコール、プロピレングリコール、グリセリン、エリスリトール、ソルビトール等の多価アルコール類、ショ糖、グルコース、ガラクトース、マルトース等の糖類との各エステルを例示することができる。
【0016】
又、アミドとしては、各種アミノ酸とりわけ生体蛋白質を構成する中性アミノ酸(アラニン、グリシン、バリン、ロイシン、イソロイシン、アスパラギン、グルタミン)、酸性アミノ酸(アスパラギン酸、グルタミン酸)、塩基性アミノ酸(アルギニン、リジン)、ヒドロキシアミノ酸(セリン、スレオニン)、環状アミノ酸(ヒスチジン、トリプトファン、チロシン、フェニルアラニン、プロリン、ヒドロキシプロリン)、含硫アミノ酸(システイン、シスチン、メチオニン)等とのアミド類が好適であり、前記各種アミノ酸の組合わせからなるペプチドとのアミド類、前記各種アミノ酸とグルコース、ガラクトース等の糖類とからなるアミノ糖とのアミド類も対象にすることができる。
【0017】
ピログルタミン酸及びその誘導体を化学的に合成するには公知の方法に従えばよく、その一例として、L−グルタミン酸と等重量の水とをオートクレーブ中で約130〜150℃程度に加熱処理するとL−ピログルタミン酸が得られ、又、約190〜200℃程度まで強熱するとラセミ化してDL−ピログルタミン酸を得ることができる。又、前記誘導体は、このL−ピログルタミン酸やDL−ピログルタミン酸を出発物質として常法により前記各種誘導体を化学的あるいは酵素的に合成すればよい。
【0018】
本発明に係るピログルタミン酸を天然物から調製するには、動植物や魚介類由来の蛋白質やペプチドを塩酸、プロテアーゼ等により加水分解し、更に分別精製する方法を利用できる。より望ましくは、担子菌類の子実体又は菌糸体を原料として用い、これを乾燥して粉末物となした後、抽出溶媒を用いて処理して抽出液となし、濃縮液となし、又、この抽出液や濃縮液を乾燥処理して抽出物となし、更には有機溶媒、吸着剤等を用いて分別、分画処理して高濃度の精製物となすことにより可能となる。本発明ではこれらをピログルタミン酸及び/又はその誘導体の好適な態様として利用する。
【0019】
ここで、担子菌類としてはシイタケ、エノキタケ、シメジ、ヒラタケ、アガリクス茸、メシマコブ茸、霊芝、ヤマブシ茸、カワラタケ、ハラタケ、マイタケ、ハナビラタケ、スエヒロタケ、シロキクラゲ、冬虫夏草からなる群から選ばれる1種又は2種以上のものを用いることが望ましい。これらのキノコの子実体はいずれも人工的に栽培され又は多量に収穫されて流通しており、容易に入手可能であり、生のまま、乾燥物、その粉末や抽出エキス等として食用に供されている。また、シイタケ、カワラタケ、スエヒロタケのように抽出物に含まれる多糖体が医薬品として利用されているものもある。本発明では、所望の効果からみて、アガリクス茸、メシマコブ、霊芝、ヤマブシ茸及び冬虫夏草からなる群から選択される1種又は2種以上がより好適であり、アガリクス茸が最も望ましい。
【0020】
アガリクス茸はハラタケ科のキノコで、アガリクス(Agaricus)属に属するものをいい、アガリクス ブラゼイ ムリル(Agaricus blazei Murill)、マッシュルーム(Agaricus bisporus)等を例示できる。前者は多糖体(β−D−グルカン)や多糖蛋白複合体を含み、抗腫瘍作用、血糖低下作用等があることが知られている。メシマコブ(Phellinus linteus)はタバコウロコタケ科のキノコで、その熱水抽出物の多糖体が抗癌作用を示すといわれている。霊芝(Ganoderma lucidum)はサルノコシカケ科のキノコでマンネンタケとも呼ばれ、テルペノイドや多糖体による抗アレルギー作用、抗腫瘍作用、血圧安定化作用、プロテオグリカンによる血糖低下作用等が知られている。ヤマブシ茸(Hericiumerinaceum)はサンゴハリタケ科に属し、ヘテロβ−D−グルカン成分による抗癌作用や活性酸素消去作用が知られている。
【0021】
本発明では、前記担子菌類の子実体は生のままあるいは乾燥物のいずれも原料として使用できるが、取扱い上、保存性及び抽出効率等の点から乾燥物がよい。又、菌糸体は適当な炭素源と窒素源を含む培地を用いて種菌を培養して得られる生あるいは乾燥菌糸体を利用できるが、子実体同様に乾燥物が簡便である。
【0022】
本発明においては、前記担子菌類の子実体又は菌糸体から本発明に係るピログルタミン酸含有抽出物を製造するために、水で抽出し、次いで親水性有機溶媒を用いて抽出すること、あるいは、水及び/又は親水性有機溶媒と、疎水性有機溶媒とを用いて抽出することを特徴とする。疎水性有機溶媒のみによる抽出物では本発明の所望の効果をほとんど発現しない。親水性有機溶媒はメタノール、エタノール、n−プロパノール、イソプロパノール又はアセトンが好ましく、疎水性有機溶媒はヘキサン又はクロロホルムが好ましい。親水性有機溶媒は水との混合物でもよく、親水性有機溶媒及び疎水性有機溶媒の各々は単一物を用いても混合溶媒で使用しても差し支えない。又、両者を混合した形態も好適である。本発明の血管新生阻害剤の有効成分を抽出する上で重要なことは、水及び/又は親水性有機溶媒、あるいはこれと疎水性有機溶媒との混合溶媒を用いて水性成分を主体とする抽出物を得、ついで親水性有機溶媒で水溶性のより高い糖類、アミノ酸等の易溶性成分を分別して除去し、又、疎水性有機溶媒で脂質類等の油性成分を分別除去する点にある。
【0023】
親水性有機溶媒と疎水性有機溶媒を混合して用いる場合の混合比率(容量比)は、前者/後者=9/1〜1/9、より好ましくは5/1〜1/5、最も好ましくは3/1〜1/1である。前記範囲を外れると本発明の必須成分の抽出効率が低下し又は所望の効果が得られないことがある。抽出溶媒は子実体や菌糸体の乾燥物、抽出物に対して3〜20倍(重量基準)程度用いる。3倍未満では抽出物の収率が低く、逆に20倍を超える多量を使用しても抽出効率がさらに向上することはない。
【0024】
抽出処理は、担子菌類の子実体又は菌糸体と前記抽出溶媒とを接触させ、常圧ないし加圧下、より好ましくは1〜3気圧下で、室温ないし100℃付近で適宜に攪拌しながら又は還流させて約10分〜約10時間抽出することにより抽出液を得ることができる。該抽出液を減圧乾燥、凍結乾燥、噴霧乾燥等の処理に供して溶媒を除去し、担子菌類の抽出物を調製することができる。また、前記抽出物を親水性有機溶媒及び疎水性有機溶媒で分別処理することによって本発明の必須成分の含量がさらに高められた濃縮物とすることができ、さらにシリカゲル、活性アルミナ、ケイ酸マグネシウム、活性炭、セルロース、イオン交換樹脂等の吸着剤を用いたカラムクロマトグラフィーに供して分画処理することにより高濃度の精製物を製造することができる。
【0025】
前述のように、化学的合成法又は担子菌類からの抽出法により調製されるピログルタミン酸及び/又はその誘導体、これを含有する抽出液、抽出物、濃縮物及び精製物は、これらをそのまま又は適当な担体、賦型剤、添加物等を併用して本発明の血管新生阻害剤となすことができる。本発明の血管新生阻害剤では、本発明の趣旨に反しないかぎり種々の原料や成分を併用して配合することができ、例えば、通常の食品や医薬品に使用される賦形剤、防湿剤、防腐剤、強化剤、増粘剤、乳化剤、酸化防止剤、甘味料、酸味料、調味料、着色料、香料等がよい。又、血管新生を抑制する作用をもつ公知の素材を併用することは本発明の望ましい態様のひとつである。
【0026】
次に、本発明の血管新生抑制及び/又は免疫賦活のための組成物について説明する。この組成物は、前記のピログルタミン酸類、望ましくは前記担子菌類から得られるピログルタミン酸含有抽出物を有効成分として含有してなる血管新生阻害剤を配合してなることを特徴とするものである。後述するように、本発明の血管新生阻害剤は、これを経口摂取することにより血管新生抑制作用を発現することに加えて、抗腫瘍作用すなわち腫瘍の増殖抑制作用及び転移抑制作用を示し、更には免疫増強作用をも発現する。したがって、かかる血管新生阻害剤は前記作用を有する組成物として活用でき、該組成物の具体的な態様としては飲食品、医薬品、ペットフード、家畜・家禽用飼料等を例示できる。とりわけ飲食品及び医薬品が好適である。
【0027】
この飲食品の態様としては、前記の担子菌類の乾燥粉末、抽出物若しくは精製物等をそのまま又はこれを含む前記血管新生阻害剤を液状、ゲル状、粉末状あるいは固形状の食品、例えば、果実飲料、清涼飲料、茶、スープ、ゼリー、ヨーグルト、プリン、ケーキミックス、ふりかけ、味噌、醤油、ドレッシング、マヨネーズ、焼肉のたれ等の調味料、麺類、ハムやソーセージ等の畜肉魚肉加工食品、ジャム、牛乳、クリーム、バターやチーズ等の粉末状、固形状又は液状の乳製品、マーガリン、パン、ケーキ、クッキー等に添加した形態となすことができる。
【0028】
また、必要に応じてデキストリン、乳糖、澱粉又はその加工素材、セルロース末等の賦形剤、ビタミン、ミネラル、動植物や魚介類の油脂、たん白質、糖質、色素、香料、その他の前記食用添加剤等と共に粉末、顆粒、ペレット、錠剤等に加工したり、ゼラチン等で被覆してカプセルに成形したり、あるいはドリンク類にして、栄養補助食品や健康食品として利用できる。このとき、血管新生阻害作用を有する公知の食用素材を併用した組成物は好適である。なお、本発明の飲食品は極めて多種類の形態にわたり、前記の例示に限定されるものではないが、前記の栄養補助食品や健康食品の形態が望ましい。
【0029】
本発明では、飲食品における本発明の血管新生阻害剤の配合量は、当該飲食品の種類、形態、利用目的や配合する血管新生阻害剤の種類、形態等により一律に規定し難いが、一般の加工食品類に添加する場合では、ピログルタミン酸ベースで概ね0.01〜50重量%、より好ましくは0.1〜30重量%である。この範囲を外れて少ないと経口摂取による本発明の所望効果が小さく、逆に多すぎると飲食品の種類によっては風味を損ねたり、当該飲食品を調製することが不可能になる場合がある。なお、本発明の血管新生阻害剤はそのまま食用に供しても差し支えない。
【0030】
本発明の医薬品としての態様は、前記の血管新生阻害剤に本発明の趣旨に反しない公知の賦形剤や添加剤を必要に応じて加え、常法により加工して錠剤、カプセル剤、顆粒剤、散剤、注射剤等の製剤となしたものである。これを経口投与あるいは経腸投与、血管投与又は皮内投与して、血管新生の抑制、腫瘍の抑制、免疫賦活のうちの少なくとも1つの作用効果を発現させるために利用でき、及び血管の新生、腫瘍の増殖や転移、免疫能の低下等にともなう各種疾病の予防又は治療のために適用することができる。本発明の血管新生阻害剤の配合量はその形態や前記医薬用製剤の種類、形態、用法及び用量等により一律に設定し難いが、ピログルタミン酸ベースで概ね0.01〜70重量%である。経口投与する場合の摂取量は特に限定されるものではないが、ピログルタミン酸をベースとして、成人(体重50Kg)1日あたり0.01〜20g、より好ましくは0.1〜10gである。この範囲を外れて少ないと所望の効果が低下し、逆に多すぎても更に顕著な効果を期待できない。
【0031】

BACKGROUND OF THE INVENTION
The present invention relates to an angiogenesis inhibitor. More specifically, pyroglutamic acid obtained from basidiomycetes Contained extract The present invention relates to an angiogenesis inhibitor comprising as an active ingredient.
[0002]
[Prior art]
Angiogenesis refers to the degradation and destruction of the vascular basement membrane by proteases in animal tissues or organs, migration and proliferation of vascular endothelial cells, adhesion to the extracellular matrix, and differentiation of vascular endothelial cells into vascular spaces. This is a phenomenon in which a new blood vessel is generated. In general, new blood vessels are formed and stretched during infancy and growth, but the scenes in which angiogenesis occurs in the body after the growth phase are limited. That is, angiogenesis is observed under normal physiological conditions such as luteinization, ovulation, embryogenesis, and placenta formation, and also occurs in the process of healing wounds and repairing inflammation. In this way, angiogenesis occurs in a healthy state and plays an important role in the recovery of tissues, but in many chronic diseases including diabetes, the increase of capillaries causes serious damage to tissues. Is also known.
[0003]
Diseases that cause angiogenesis or are associated with worsening pathological conditions include growth and metastasis of malignant tumors, diabetic retinopathy, neovascular glaucoma, inflammatory skin diseases, rheumatoid arthritis, osteoarthritis, and sagittal artery There are occlusive diseases such as sclerosis and myocardial infarction.
[0004]
For example, when a malignant tumor grows, in order to obtain nutrients and oxygen necessary for the growth of the tumor cells, the tumor cells themselves induce the formation of blood vessels by angiogenesis-promoting factors and obtain nutrients through the newly formed blood vessels. Tumor cells grow further. Metastasis to other organs or sites also induces angiogenesis, and tumor cells move along the bloodstream. In the case of diabetic retinopathy, capillaries are clogged by the viscous blood due to diabetes, resulting in bleeding and edema in the retina. When this becomes chronic, the retina causes a lack of oxygen and nutrients. New blood vessels develop on the nervous system papillae, and fibrous tissue is formed around them. This fiber tissue pulls up the retina (retinal detachment), tears the blood vessels of the retina, causes bleeding (vitreous hemorrhage), and eventually leads to severe visual impairment and blindness.
[0005]
As described above, angiogenesis is deeply involved in the onset and progression of various diseases. Therefore, many substances have been searched for to suppress angiogenesis with the aim of treating and preventing these diseases. Research is being promoted. Examples of substances and drugs having an action of inhibiting angiogenesis include sulfated polysaccharides (see, for example, Patent Document 1), trafermin, heparin and steroids (for example, see Patent Documents 2 and 3), ascorbic acid ether and Related compounds (for example, see Patent Document 4), interferon α or interferon β (for example, see Non-Patent Document 1), thiazole derivatives (for example, see Patent Document 5), shark cartilage extract (chondroitin and mucopolysaccharide) (for example, Patent Document 6), polysaccharides derived from Streptococcus bacteria (for example, see Patent Document 7), O-substituted fumagillol derivatives (for example, see Patent Document 8), neoagaro-oligosaccharides (for example, see Patent Document 9) and the like have been proposed. ing.
[0006]
However, the substances that have been proposed and studied as substances exhibiting the action of inhibiting angiogenesis so far are based on experimental results under administration conditions where the effect is not practical, there are concerns about side effects, Alternatively, it must be ingested in a large amount in the form of use, and none of them can exhibit a sufficiently satisfactory effect when considering practical use. For this reason, it is required to develop a substance that more strongly inhibits angiogenesis and has no safety concerns.

Test example 2
Various samples according to the present invention were tested and evaluated for tumor growth inhibitory effect and metastasis inhibitory effect by the following methods. That is, Lewis lung cancer (hereinafter abbreviated as LLC) cells that were sold by RIKEN were suspended in a phosphate / saline buffer (pH 7.4). On the other hand, 6 weeks old C57BL / 6J female mice (purchased from Japan Claire Co., Ltd.) were preliminarily raised for 1 week, then healthy mice (8 mice per group) were subjected to small incision under Nembutal anesthesia to expose the spleen LLC cell suspension (LLC cell number: 1 × 10 5 The small incision was sutured immediately after injection. From 12 hours after LLC cell transplantation, Agaricus sputum extract (Sample 1) 100 mg / Kg (body weight) or 300 mg / Kg (body weight) was orally administered once a day for 30 consecutive days. Instead of sample 1, distilled water was administered to the normal group and the control group (LLC tumor-bearing mice). During this test period, the degree of proliferation of cancer cells is determined every 3-5 days by volume of cancer tissue (major axis x minor axis). 2 / 2) was measured. On the 31st day after cancer transplantation, blood was collected from each group of mice under ether anesthesia and heparinized blood, and the number of leukocytes, red blood cells and hemoglobin in the blood were measured with a blood cell counter. Tissue, liver, lung, spleen and thymus were removed and the weight of each tissue was measured, and the number of cancer cell colonies that had metastasized to lung tissue was counted under a stereoscopic microscope.
[0044]
