Abstract
Description
本発明は第一方面において、哺乳動物(例えば、人間)のエストロゲン分泌不足と関連する病気を治療及び/又は予防するのに用いる薬物調製における鎖陽の用途を提供する。
40.0キログラムの鎖陽薬材(内蒙古阿拉善盟から購入)を小さく砕いてから、400リットルの95%エタノールを加入し一夜浸した。2時間にわたり逆流抽出し、抽出液を流し出して、残渣にまた400リットルの60%エタノールを加入し、2時間逆流抽出を行った。抽出物を合わせてから濾過し、濾液を旋蒸しエタノールを回収した。濃縮して得た残留物は順次に石油エーテル、クロロホルム、酢酸エチルとブチルアルコールを使って抽出し、薬剤をそれぞれ回収して固形物を得た。結果:石油エーテル部分固形物55g、クロロホルム部分固形物229g、酢酸エチル部分固形物147g、ブチルアルコール部分固形物867g。石油エーテル部分のクリソファノール質量含有量は0.082%(W/W)、クロロホルム部分は0.031%(W/W)のエモジンを含み、酢酸エチル部分のカテキン質量含有量は10.84%(W/W)、酢酸エチル部分のナリンゲニン−4’−O−グルコシド質量含有量は0.304%(W/W)、酢酸エチル部分の(−)エピカテキン−3−O−ガレート質量含有量は0.88%(W/W)、酢酸エチル部分のフロリジン質量含有量は0.28%(W/W)である。
鎖陽石油エーテル部分55gを、シリカゲルカラムクロマトグラフィーした後、石油エーテル−酢酸エチル溶剤システムを採用し勾配溶離を行い、3〜4流部石油エーテル再結晶処理を経て、橙紅色の束ねた形の結晶30mgを得た。鑑定によると、クリソファノールである。
実施例1において獲得した六つの化合物(即ち、クリソファノール、エモジン、カテキン、(−)エピカテキン−3−O−ガレート、ナリンゲニン−4’−O−グルコシド、フロリジン)に対して構造確認を行った(天津大学分析測試センターに委託して測定した。500MHz核磁)。分析結果はこれらの化合物の構造は文献記述における構造と一致していることを示した。具体的には以下のようである:
細胞トランスフェクション方法を採用し、カテキン、(−)エピカテキン−3−O−ガレート、ナリンゲニン−4’−O−グルコシド、フロリジン、エモジン、クリソファノールのエストロゲン受容体に対する選択的活性化を観察した。実際に、エストロゲンは確かにエストロゲン反応遺伝子転写を調節することを通じて、その生物活性を示すのである。
カテキン、(−)エピカテキン−3−O−ガレート、ナリンゲニン−4’−O−グルコシド、フロリジン、エモジン、クリソファノールから相応の質量をそれぞれ精密に量り取った後、DMSOに加入して溶解した。対応したサンプル液高分量組(10μM又は1μM)と、一定の倍量に希釈して低分量組(1μM又は0.001μM)をそれぞれ得た。
鎖陽酢酸エチル部分(実施例所得の147g物質から取る)と石油エーテル部分(実施例所得の55g物質から取る)から相応の質量を精密に量り取った後、DMSOに加入し溶解した。対応したサンプル液高分量組(50ug/ml)と、一定の倍量に希釈して低分量組(5ug/ml、0.5ug/mlと0.05ug/ml)をそれぞれ得た。
