in vitro 薬理活性
薬理活性は、in vivoの抗炎症または抗アレルギー活性を一般的に予測できる、グルココルチコイド作用物質活性の機能的in vitroアッセイで評価した。
in vivoでの薬理活性を、卵アルブミン感作したBrown Norway ラット好酸球増加症モデルで評価した。このモデルは、模擬アレルゲン誘導された肺好酸球増加症と呼ばれ、喘息における肺炎症の主要素である。
化合物(I)を、ラットまたはヒトの肝細胞と共にインキュベーションすることによって、化合物がプロピオン酸フルチカゾンと同一の方法で代謝されることが示され、17-βカルボン酸(X)が、生成される唯一の重要な代謝物であった。化合物(I)のヒトの肝細胞と一緒のインキュベーション(37℃、10μMの薬剤濃度、3対象からの肝細胞、200,000および700,000個の細胞/mL)におけるこの代謝物の出現の速度の研究は、化合物(I)がプロピオン酸フルチカゾンより約5倍速く代謝されることを示す。
化合物(I)を、オスのWistar Han ラットに経口投与(0.1mg/kg)およびIV(0.1mg/kg)投与し、薬物動力学パラメータを決定した。化合物(I)は、ごくわずかな経口バイオアベイラビリティー(0.9%)および肝臓の血流にほぼ等しい47.3mL/分/kgの血漿クリアランスを示した(プロピオン酸フルチカゾンの血漿クリアランス=45.2 mL/分/kg)。
麻酔したブタ(2)に、乳糖中の乾燥粉末ブレンド(10%重量/重量)として、化合物(I)(1mg)およびプロピオン酸フルチカゾン(1mg)の均質混合物を気管内投与した。投与後8時間までにつき逐次血液試料を取った。化合物(I) およびプロピオン酸フルチカゾンの血漿濃度を、LC-MS/MS法を用いた抽出および分析後に決定し、この方法の定量の下限は、化合物(I) およびプロピオン酸フルチカゾンについてそれぞれ10pg/mLおよび20 pg/mLであった。これらの方法を用いると、化合物(I)は投与後2時間まで定量可能であり、プロピオン酸フルチカゾンは投与後8時間まで定量可能であった。最大血漿濃度は、両方の化合物について投与後15分以内に観察された。IV投与(0.1mg/kg)から観察された血漿半減期データを使用して、化合物(I)についてAUC(0-inf)値を計算した。化合物(I)の血漿プロファイルについてのこの補正はIT投与後2時間までにのみ定義され、化合物(I) およびプロピオン酸フルチカゾン間の限られたデータによるいかなる偏向をも除去される。
