Abstract
Description
3−[(1S,2S)−3−(ジメチルアミノ)−1−エチル−2−メチル−プロピル]フェノールの薬物動態プロファイル
in vivoでの代謝クリアランスの異なる経路の可能性は、肝ミクロソームなどの細胞下画分を使用して、in vitroでの基本的な酸化または抱合反応の割合を推定することによって調べることができる。3−[(1S,2S)−3−(ジメチルアミノ)−1−エチル−2−メチルプロピル]フェノールのミクロソームの酸化の割合がきわめて低くなることが示されることもありえたので、酸化的代謝がこの分子の重要な代謝クリアランス経路である可能性は低いと考えられた。3−[(1S,2S)−3−(ジメチルアミノ)−1−エチル−2−メチルプロピル]フェノールの鏡像異性対掌体(以下、3−[(1R,2R)−3−(ジメチルアミノ)−1−エチル−2−メチルプロピル]フェノール)についても、同様に低い割合のミクロソームの酸化が実証された。
急性侵害受容性疼痛の動物モデルにおけるくも膜下薬剤投与後の3−[(1S,2S)−3−(ジメチルアミノ)−1−エチル−2−メチルプロピル]フェノールの効力
ラットの脊髄内への局所的な薬剤適用後の低強度テールフリック試験において、3−[(1S,2S)−3−(ジメチルアミノ)−1−エチル−2−メチルプロピル]−フェノールの抗侵害受容作用を評価した。
動物
商業的ブリーダー(Janvier、Le Genest St Isle、France)からの160匹の雄のSprague Dawleyラット(体重200〜260g)を、標準化された以下の条件下で収容した:明/暗周期(06.00〜18.00時 明、18.00〜06.00時 暗);室温20〜24℃;相対空気湿度35〜70%;1時間あたり15回の換気、空気移動0.2m/秒未満。これらの動物に、水およびラット/マウス/ハムスター用に設計されているNohrlin(Bad Salzuflen、FRG)からの飼料を自由に与えた。これらを、Makrolonケージ4型内で6つの群で維持した。送達の日と試験の日との間には少なくとも5日間あった。
この実験は、Rhema−Labortechnik(Hofheim/Ts.、FRG)からのテールフリック装置を使用して行った。薬剤適用の前後に、放射熱ビームを、根元から約2〜4cm離れたラットの尾の背側表面に集中させた。試験中、動物を拘束した。ランプのスイッチを入れてから尾の逃避までの潜時を測定した。放射熱ビームの強さは、4.5〜9秒の予備試験平均値が各動物群で得られたような、最大値の40%に調整した。15秒以下の予備試験の潜時を示し、しかもその予備試験の値が2秒を超えて異なっていなかった動物のみを試験に使用した。組織損傷を回避するために、尾が逃避しなかった場合には、遅くとも30秒後に放射熱ビームのスイッチを切った。適用10、20、30、60、90および120分後に動物を試験した。3−[(1S,2S)−3−(ジメチルアミノ)−1−エチル−2−メチルプロピル]フェノールのくも膜下投与は、軽いエーテル麻酔下でL1とL3との間に注射することによって行った。対照群は、0.9%の生理食塩水で処置した。
以下の式に従って、個々の潜時を、可能な最大効果の百分率(%MPE)として算出した:
%MPE=(潜時−VTM)/(30秒−VTM)*100%
VTM:予備試験平均値、30秒:カットオフ値。
3.15μg/匹のくも膜下(i.t.)投与後、3−[(1S,2S)−3−(ジメチルアミノ)−1−エチル−2−メチルプロピル]フェノールは、図1に示されているように、長期持続性で適用20分後に59.71±2.94%MPEの最大に達する抗侵害受容作用を誘導した。
