1.他のステロイドホルモン受容体と比べた阻害性MR活性およびMR選択性を測定するための細胞インビトロ検定法
ヒト鉱質コルチコイド受容体(MR)のアンタゴニストを同定し、組換えセルラインを採用して本明細書記載の化合物の活性を定量する。この細胞は、ハムスター卵巣上皮細胞(チャイニーズハムスター卵巣、CHO K1、ATCC:アメリカン・タイプ・カルチャー・コレクション、バージニア20108、米国)に由来する。
GAL4−ステロイドホルモン受容体キメラを生成するため、ベクターpFC2−dbd(Stratageneから)からのGAL4 DNA結合ドメイン(アミノ酸1〜147)を、鉱質コルチコイド受容体(MR、アミノ酸734〜985)、グルココルチコイド受容体(GR、アミノ酸443〜777)、プロゲステロン受容体(PR、アミノ酸680〜933)およびアンドロゲン受容体(AR、アミノ酸667〜919)のPCR増幅リガンド結合ドメインと共にベクターpIRES2(Clontechから)へクローン化する。チミジンキナーゼプロモーターのGAL4結合部位上流の5コピーを含むリポーター構築物は、それぞれの特異的アゴニスト、アルドステロン(MR)、デキサメタゾン(GR)、プロゲステロン(PR)およびジヒドロテストステロン(AR)によるGAL4−ステロイドホルモン受容体キメラの活性化および結合後に蛍ルシフェラーゼ(フォチナス・ピラリス、Photinus pyralis)の発現を誘導する。
MR、GR、PRおよびAR細胞を、検定前日に96−(または384−または1536−)ウェルのマイクロタイタープレートにおける培地(Optimem、2.5%FCS、2mMグルタミン、10mMのHEPES)で培養し、細胞インキュベーター(96%湿度、5%v/vCO2、37℃)中で維持する。検定当日、試験すべき物質を上記培地中に取り、細胞に加える。試験物質添加の約10〜30分後、ステロイドホルモン受容体のそれぞれの特異的アゴニストを加える。5〜6時間のさらなるインキュベーション期間後、ビデオカメラの助けを借りてルシフェラーゼ活性を測定する。物質濃度の関数として測定された相対光単位は、S字状刺激曲線を形成する。GraphPad PRISMコンピュータープログラム(バージョン3.02)の助けを借りてIC50値を計算する。
ウィスターラットの大脳皮質の膜調製物は、標準検定法として文献[Ehlert,F.J., Roeske,W.R., Itoga E., Yamamura,H.I., Life Sci.30, 2191-2202(1982);Gould,R.J., Murphy,K.M.M., Snyder,S.H., Proc.Natl.Acad.Sci. U.S.A., 79、3656-3660]で詳述されている放射性結合検定法用の出発物質であり、民間のサービス提供者(例、MDS Pharma Services)との契約による研究で使用される。この結合検定法では、DMSO中の試験化合物の系列希釈液を、25℃で典型的には90分間、50mMのトリスHCl緩衝液、pH7.7中において膜調製物およびトリチウム標識リガンドニトレンジピン(0.1nM)とインキュベーションし、試験化合物の特異的結合を、特異的に置換された、放射性標識リガンドを定量することにより測定する。非線型回帰分析により、IC50値を測定する。
雄のニュージーランド白ウサギの新たに分離した胸大動脈を取り出し、周囲組織を取り除く。次いで、長さ2mmの大動脈輪を、37℃に加熱したクレブス−ヘンゼライト溶液と共に10mlの臓器部分中4gの初期緊張下におく。45分間隔で4回40mMのKCl(最大レベル下の収縮)および15mMのKCl(最小収縮)により収縮を誘導することにより、血管を徐々に伸ばし、安定した静止張力を生じさせる。各収縮の後、一連の11洗浄サイクルを行い、再び先の緊張を加えながら30分の静止期間をおく。4回のプレ-ラン後、それ以上緊張を加えずに、試験物質を、静止期間開始時にそれぞれの場合における臓器浴に加える。試験物質の濃度を、4回の後続収縮の各々について10倍の率で高める。効果を計算するため、ベースライン張力および4回目のプレ-ラン収縮に関する値間の差異を100%に設定し、後続の収縮ピークとこの値との相関関係を明らかにする。この実験手順により、試験物質のカルシウム−アゴニスト的効果(最大レベル下の収縮で微増、最小収縮で大きな増加)およびカルシウム−アンタゴニスト的効果(最大レベル下の収縮で低下、最小収縮で大きな低下)を識別することが可能となる。
ウィスターラット(体重250〜350g)を、飼料(Altromin)および飲用水へ自由に接近できる状態で保つ。試験開始の約72時間前から、通常の飼料ではなく塩化ナトリウム含有率が0.02%の減塩飼料(ssniff R/M-H、0.02%Na含有10mm、S0602−E081、ssniff Spezialdiaten GmbH、D−59494 ゾースト)のみを動物に与える。試験中、動物をこの体重クラスのラットに適した代謝ケージ(Tecniplast Deutschland GmbH、D−82383 ホーヘンペイシェンベルグ)に、約24時間、減塩飼料および飲用水には自由に近づける状態で単独収容する。試験開始時、試験すべき物質を、体重に基づき0.5ml/kgの容量の適切な溶媒で胃管栄養法により動物の腹部に投与する。対照動物には溶媒のみを与える。対照および物質試験を同日に平行して実施する。対照群および物質投与群は、各々3〜6動物により構成される。試験中、動物が排泄した尿を、ケージの基部に設けた受け容器に連続的に集める。単位時間当たりの尿量を、各動物について別々に測定し、尿中に排泄されたナトリウムおよびカリウムイオンの濃度を、標準的炎光光度計測定法により測定する。ナトリウム/カリウム比を、物質の効果の尺度として測定結果から算出する。測定間隔は、典型的には試験開始後8時間以下の期間(昼間)および試験開始後8〜24時間の期間(夜間)である。改変した試験デザインでは、尿を集め、日中2時間間隔で測定する。この目的にとって十分な量の尿を入手するため、試験開始時、次いで2時間間隔で動物には規定量の水を胃管栄養法により与える。
