Abstract
【解決手段】 これまでの小型動物での試験結果から想定されていたダイズイソフラボンによる骨粗鬆症の予防又は治療効果に疑問を持ち、霊長類モデルを駆使して骨粗鬆症の予防又は治療効果を示す新たなダイズ有効成分を特定した。骨粗鬆症の予防又は治療剤は、β−コングリシニン及び/又はプロテアーゼによるその加水分解物を有効成分として含み、製剤中のβ−コングリシニン及びプロテアーゼによるその加水分解物の含量が15重量%以上である。

Description
(1) 材料
乾燥状態で水分7.1%及びタンパク質55.5%を含む市販の低温加工脱脂大豆フレーク(不二製油、日本国大阪)を使用した。フィターゼ(Phytase NOVO L)はNOVO industry Co.より得た。
脱脂大豆フレークを10倍量の水中に分散させた。懸濁液のpHを2MのNaOHで7.5に調整し、該懸濁液を1時間室温にて撹拌した。3,000×gで10分間遠心し、上清を脱脂豆乳として採取した。100gの脱脂大豆フレークから脱脂豆乳中32gのタンパク質を得た。該脱脂豆乳を2MのHClでpH6.0に調整した。該豆乳にフィターゼを加え(1000FYT/100g脱脂豆乳中タンパク質)、得られた混合物を1時間40℃に保温した。該溶液を室温にて遠心し沈殿を分離した。遠心により採取した沈殿を4倍量の蒸留水中に分散し、2MのNaOHでpH7.0に中和した(グリシニン画分)。上清は2MのHClでpH5.0に調整して遠心した。沈殿を4倍量の蒸留水中に溶解し、2MのNaOHでpH7.0に中和後さらに等電点沈殿法で精製(β−コングリシニン画分)した。得られたβ−コングリシニン画分を以下の実験においてカニクイザル骨粗鬆症モデルに投与した。なお、得られたβ−コングリシニン画分中には、SDS-PAGEによる分析の結果、β−コングリシニン及びグリシニン以外のタンパク質は含まれていなかった。また、β−コングリシニン画分中のβ−コングリシニンの含量は、約92重量%であった。なお、β−コングリシニンの含量は、SDS-PAGE上のβ−コングリシニンのサブユニット鎖のデンシトメトリー(濃度解析)により測定した。
イソフラボン製剤としては、公知のイソフラボン製剤(商品名「ソヤフラボンHG」、不二製油製、イソフラボン含量52.2重量%)を用いた。
カニクイザルメス成獣の卵巣を摘除(OVX)した。摘除後10週間、血中エストローゲンレベルをサーベーし、卵巣摘除によってエストローゲンの血中レベルが検出限界以下であることを確認した。これは、卵巣機能(エストローゲンの産生/放出)がなくなり、完全閉経状態であることを意味する。
