Abstract
Description
1.酸化が賦形剤中の過酸化物および金属不純物の存在により引き起こされる場合、医薬製剤中の活性物質の濃度を増大させる;
2.賦形剤中に存在する金属不純物を除去するために、キレート剤(例えば、クエン酸、EDTA、フマル酸およびマレイン酸)を添加する;
3.高純度の薬学的賦形剤を使用する;
4.特に過酸化物不純物により賦形剤が酸化の原因となる場合、代わりの薬学的賦形剤を使用するか、医薬組成物中の賦形剤の量の低減する;
5.医薬組成物中の過酸化物の形成を阻止または軽減することが可能な抗酸化剤を使用する。
しかし、かかる抗酸化剤はすでに存在する過酸化物のレベルを同時に低減しない。いくつかの適切な抗酸化剤はすでに記載されており、
−連鎖停止剤(例えば、チオール類およびフェノール類);
−還元剤(例えば、亜硫酸塩およびアスコルビン酸)であり、活性物質に比べより容易に酸化され、したがって存在する酸素を除去する還元剤、ここでそれらの組合せは相乗的に作用し得る(例えば、アスコルビン酸パルミチン酸エステル(ascorbic palmitate)とトコフェロールの組合せ);
−フェントン処理の原理で過酸化物(例えば、Fe2+)を分解する過酸化物のスカベンジャー。しかし、この処理により、さらにフリーラジカルの反応およびしたがって活性物質の分解を誘起することのある、フリーのヒドロキシラジカルが形成され得るため、それらの使用は制限される。
−酸化を受ける活性物質の部位を覆うシクロデキストリン(Waterman,K.C等による、“Stabilization of Pharmaceuticals to Oxidative Degradation”,Pharmaceutical Development and Technology,7(1),2002,1−32)、
を含む。

Hurley,T.R.等の文献、Tetrahedron 49,1993,1979−1984に記載のアトルバスタチンカルシウムの酸化分解生成物は、下記の化学式IV:
5グラムのアトルバスタチンカルシウムを200mlの密閉容器内において酸素雰囲気中、80℃で30日間保存した。このように調製した試料を50%アセトニトリル/水(vol/vol)中に溶解し、分取クロマトグラフィーに供した。
フラクション2を精製するためのクロマトグラフ条件は、移動相Aの溶媒が70%の10mMリン酸緩衝液pH7.0/25%のアセトニトリル/5%のテトラヒドロフラン(vol/vol/vol)であり、および以下のグラディエントプロファイルを用いた以外、最初の分離時の条件と同じであった。
フラクション3を精製するためのクロマトグラフ条件は、移動相Aの溶媒が5mMの塩酸であり、および以下のグラディエントプロファイルを用いた以外、最初の分離時の条件と同じであった。
フラクション4を精製するためのクロマトグラフ条件は、以下のグラディエントプロファイルを用いた以外、フラクション3の精製条件と同じであった。
質量分析法:
条件:
高分解能マススペクトルを四重極飛行時間型質量分析計(quadrupole time−of−flight mass spectrometer)Micromass Q TOF Ultra Globalを用いて得た。エレクトロスプレーイオン化を用いた。ソース温度を100℃に、脱溶媒和温度を200℃に、コーンガスを0L/時および脱溶媒ガスを200L/時に設定した。W形状のTOF分析器を用いた。装置はギ酸Naクラスターを用いて検量した。試料を5mMの酢酸アンモニウム/アセトニトリル(vol/vol)の50%溶液中に溶解し、10μl/分の一定流速で質量分析計に注入した。試料溶液の濃度は0.05mg/mlであった。アトルバスタチンカルシウム塩を高分解能測定に対する内部標準として用いた。0.01mg/mlの濃度の内部標準を試料溶液に加えた。
条件:
1Hおよび13C測定を300MHz Varian instrument INOVAまたはUNITY300で行った。INOVA装置は、5mm逆検出パルス磁場勾配プローブが備えられていた。1Hおよび13Cスペクトルは室温で測定した。試料はメタノール、クロロホルム、またはメタノールおよびクロロホルム2:1の混合液中に溶解した。ppmにおける化学シフトは溶媒の残留信号に関連して与えられた。

構造:
80%のアセトニトリルおよび20%の水(vol/vol)の中に、1ml当たり1mgのアトルバスタチンを含有する、2リットルのアトルバスタチン溶液を調製した。溶液を浅い晶析皿に入れ、太陽の光に5時間曝した。その後直ちに溶液を1Mの水酸化カリウム溶液でpH8から9になるまでアルカリ性化し、減圧下、濁りが最初に生じるまで蒸発させた。水浴の温度を30℃より低く維持し、凝縮器を0℃の水で冷却した。次いで最少量のアセトニトリルを添加することにより溶液が澄明になった。

アセトニトリル中に、1ml当たり10mgのアトルバスタチンを含有する、800mlのアトルバスタチン溶液を調製した。4mlの12M水酸化ナトリウムおよび40mlの30%過酸化水素を加えた。溶液を55℃で5時間撹拌した。反応混合物を放冷し、上澄みを静かに移した。上清を減圧下で約50mlになるまで蒸発させた。残存する水を捨て、固体の残渣を新しい水で洗浄した。次いで固体残渣をアセトニトリルに溶解した。
分取クロマトグラフィーおよび構造解析を実施例1と同じ方法により行った。230mgの純粋なATV−シクロIP化合物を凍結乾燥により濃縮したフラクションから単離した。クロマトグラフ純度は98.3%であった。
