Abstract
【解決手段】 本発明は、骨粗鬆症の女性を予防または処置する際のバクチオールまたはバクチオールを含む抽出物の新規な使用を開示するものである。このような新規な使用の一実施態様としては、局所適用される、経口投与される、注射されるまたは徐放性の投与形態である、バクチオールまたはバクチオールを含む抽出物を含む薬剤組成物がある。
【選択図】 なし
Description
(i)ソラレアエ フルクタス(Psoraleae fructus)を有機溶剤で抽出し;
(ii)上記(i)の抽出段階で得られた溶液を濃縮し;さらに
(iii)上記(ii)の段階で得られた濃縮液をシリカゲルクロマトグラフィーで分離して、バクチオールは含むがソラレン及びイソソラレンを実質的に含まない抽出物を得る
段階によって得られる、上記(7)に記載の薬剤組成物。
(b)上記(a)の抽出段階で得られる溶液を濃縮し、溶出剤としてn−ヘキサン及び酢酸エチルの混合溶液(n−ヘキサン:酢酸エチル=9:1)を用いて、シリカゲルカラムクロマトグラフィーでこの濃縮液を分離して、(1)脂質を含む溶出液、及び(2)バクチオールを含む溶出液を順次得る、または(1)脂質及び(2)バクチオールを含む溶出液を集める段階。
300gのソラレアエ フルクタス粉末を、2.4リットルのアセトンで抽出し、この混合物を固相及び液相に分けた。上記抽出及び固体/液体の分離を、3回繰り返した。濾液を合わせて、溶剤を留去することにより、72.11gの油状抽出物を得た。22gの油状抽出物を、300gのシリカゲル(Merck Co., Silica gel 60, mesh 70-230)を充填したシリカゲルカラム(9.6×25cm)で分離した。n−ヘキサン/酢酸エチル(9:1)の混合液、アセトン、及びメタノールを、順次溶出液として用いて、カラムを溶出した。最初に、25本のn−ヘキサン/酢酸エチル(9:1)による溶出液の入った瓶をカラムから集めた。次に、アセトンによる溶出液の入った瓶10本(26〜35番目)をカラムから集めた後、メタノールによる溶出液の入った瓶10本(36〜45番目)をカラムから集めた。この際、300mlの溶出液ごとに(即ち、1本の瓶当たり、300ml)となるように、溶出液をそれぞれ集めた。この溶出液をシリカゲルの薄層クロマトグラフィー(TLC)で、UVランプまたはヨウ素蒸気を用いてn−ヘキサン/酢酸エチル(9:1)の混合液によって発色させて、同定した。TLCで分析して同様の成分であるとされた成分を含む溶出液の入っている瓶を合わせた。
材料:DMEM(培地)、RPMI(培地)、L−グルタミン、ペニシリン、ストレプトマイシン及びFBS(ウシ胎児血清)は、Gibco (NY, USA)から得た。培養用プラスチック製品は、Corning (MA, USA)から得た。タモキシフェンは、Sigma-Aldrich (MO, USA)から得、CCK−8(細胞計測キット、新しい水溶性テトラゾリウム塩)は、Dojindo Molecular Technologies (MD, USA)を得た。使用される他の全ての化学薬品は、試薬グレードであり、SigmaまたはE. Merck (Germany)から購入した。
本実施例は、骨粗鬆症を治療する際のバクチオールの有効性を示すことを目的とする。この際、メスラットの卵巣は、エストロゲン欠乏によって生じる骨粗鬆症を刺激するために取り除いた。
16週齢のメスのWistar系ラット(他の実験でも、特記しない限り、同様の動物を使用した)は、台湾タイペイ所在の動物の飼育センターである、National Scientific Councilから得た。ラットからの生理学的応答の変動を各群毎に平等に分類できるように、これらのラットを体重が同じになるようにグループ分けした。これらのラットを以下のような群に分けた。
薬剤を加えない飼料を与えた擬似手術群(Sham)(n=10);
薬剤を加えない飼料を与えた卵巣摘出術群(OVX)(n=8):
実施例1で得られたバクチオール(5mg/kg)を加えた飼料を与えた卵巣摘出術群(OVX+A)(n=9);
実施例1で得られたバクチオール(15mg/kg)を加えた飼料を与えた卵巣摘出術群(OVX+B)(n=9)。
5mg/kg及び15mg/kgの投与量になるように、試験薬剤(実施例1で得られたバクチオール)を秤量し、これを一般的なフード・チャック(food chuck)粉末中に加えて、10%デンプンペーストと混ぜた。十分混ぜた後、これらのチャック粉末を手で塊にして、空気循環式のオーブン(air flow oven)で乾燥した。薬剤が添加された飼料を単純盲検法によってラットに与えた。
本標識付け及び骨の組織形態学的な評価は、骨の研究で標準的な方法(Lin et al, Calcif. Tissue Int., 67, 373-377 (2000))を基に行なった。試料を、ビリャヌエバ骨染料(Villanueva bone stain)で予め染色した後、脱灰し、ロンドンレジン(London resin)中に包埋した。7μm厚の脱灰しなかった切片を、Jung−Kミクロトーム(Jung-K microtome)(Leica Ltd, USA)を用いて切断し、ビリャヌエバ染料で処理して、光学顕微鏡下で観察した。7μm厚の未染色の切片を、蛍光顕微鏡用に調製し、オステオメジャープログラム(program Osteomeasure)(3.0 version, Atlanta, USA)で評価した。Lin et al. (Lin et al, Calcif. Tissue Int., 67, 373-377 (2000))に従って、骨容積(図1)及び浸食面パラメーター(図3)を得た。なお、本実験は、the Animal Center及びIAACU, National Defense Medical Center, National Defense University, Taipei, Taiwanの特別なプロジェクトライセンスの下で行なわれた。
剖検後、脛骨及び大腿骨全体から、付着している筋肉及び靭帯から剥離した。見かけの骨密度の測定は、デンシトメトリーフレーム(densitometry frame)を備えた電子秤でアルキメデスの浮力に関する原理(Archimedes floating principle)に基づいて行なった (Danielsen et al., Calcif. Tissue Int., 52, 26-33 (1993))。空気中で測定された骨の重量を、「W−air」と記載する。また、水中で同様にして秤量した骨の重量を、「W−water」と記載する。見かけの骨密度は、式:(W−air)/[(W−air)−(W−water)](gm/cm3)として算出された(図2、脛骨の見かけの骨密度)。
これらの結果は平均値及び標準偏差(S.D.)で表わされ、さらにデータを加工するために、SPSS 8.0の統計学的なパッケージ(statistical package of SPSS 8.0)(SPSS Inc, Chicago, USA)に移した。有意差があることが示された後、Bonferonni有意差法(Bonferonni significant difference method)を、一方向ANOVA(one-way ANOVA)での複数比較を試験するpostHocで使用した。
本発明を上記したように説明してきたが、本発明の概念を逸脱しない限り、本発明の様々な変更や修飾が可能であり、この際、本発明の概念は特許請求の範囲で規定される。
