in vitroでの薬理活性
薬理活性を、一般的にはin vivoでの抗炎症または抗アレルギー活性を予測する、糖質コルチコイドアゴニストの機能的in vitroアッセイにおいて評価した。
in vivoでの薬理活性を、オバルブミン感作Brown Norwayラット好酸球増加症モデルにおいて評価した。このモデルは、喘息における肺炎症の主要な構成要素である、模倣アレルゲンにより誘導された肺好酸球増加症に対して設計されたものである。
化合物(I)とラットまたはヒト肝細胞とのインキュベーションは、この化合物がプロピオン酸フルチカゾンと同一の様式で代謝されると共に、17-βカルボン酸(X)が産生される唯一の有意な代謝物であることを示している。化合物(I)とヒト肝細胞とのインキュベーション(37℃、10μM薬剤濃度、3人の被験者からの肝細胞、0.2および0.7x 106個の細胞/mL)におけるこの代謝物の出現速度の精査により、化合物(I)がプロピオン酸フルチカゾンよりも約5倍速く代謝されることが示される:化合物(I)については中央代謝物産生102〜118 pmol/h、プロピオン酸フルチカゾンについては18.8〜23.0 pmol/h。
化合物(I)を、雄のWistar Hanラットに経口(0.1 mg/kg)およびIV(0.1 mg/kg)投与し、薬物動態パラメーターを測定した。化合物(I)は、ごくわずかの経口生体利用率(0.9%)および肝臓血流に到達する47.3 mL/分/kgの血漿クリアランス(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)を示した。
麻酔したブタ(2)に、ラクトース中の乾燥粉末ブレンド(10% w/w)として、化合物(I)とプロピオン酸フルチカゾン(1 mg)の均一な混合物を気管内投与した。連続血液サンプルを、投与後8時間まで取得した。化合物(I)およびプロピオン酸フルチカゾンの血漿レベルを、LC-MS/MS法を用いる抽出および分析に従って決定したところ、この定量法の低い方の限界は、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10および20 pg/mLであった。これらの方法を用いて、化合物(I)は投与後最大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最大8時間まで定量可能であった。最大血漿濃度は、両化合物について、投与後15分以内に観察された。IV投与(0.1 mg/kg)から得られた血漿半減期データを用いて、化合物(I)についてのAUC(0-inf)値を算出した。これは、IT投与後2時間まで規定されるのみの化合物(I)の血漿プロフィールを相殺し、化合物(I)とプロピオン酸フルチカゾンとの間の制限されたデータに起因するいかなる偏りも除去する。

中間体3(0.2 g)、ジエチルアミン(5 ml)およびアセトニトリル(0.2 ml)の混合物を21℃にて18時間攪拌した。固体を濾過により回収し、減圧下で約2時間乾燥させたところ、表題の複合体が得られた。
中間体2(200 mg)を、還流下でジプロピルアミン(25 mL)に溶解した。溶媒の容量を、透明な溶液がちょうど白濁するまで、大気圧下で蒸留により減少させた。次いで、熱溶液を21℃に冷却した後、固体を濾過により回収し、濾紙上で10分間乾燥させたところ、表題の複合体が得られた。
