本発明の化合物は、重要な薬理学的特性を示し、このことはいくつかのインビトロ試験およびインビボ試験において示されている。
結合アッセイは、以下に説明されているように、標準方法に従ってトランスフェクションした細胞膜(例えばCHO)から得られた組換えヒト受容体、hSSTR1、hSSTR2、hSSTR3およびhSSTR5の調製物を使用することによって行った。
本発明の化合物はまた、ラット下垂体細胞を対象としてインビトロで実施した試験から示されるように、成長ホルモン放出(GH)の阻害活性を示す。成熟雄ラット(CD1−SD、175〜200g)から取り出した下垂体を小さい断片に切断し、1%BSA、20mM Hepes、抗体を含むハンクス緩衝液中、コラゲナーゼ(1mg/ml)とともに37℃で20分間インキュベートする。分散された細胞を、緩衝液で数回洗浄した後、48ウェルプレート中に20000細胞/ウェルで分注し、6〜7日間培養する(5%胎児ウシ血清、5%ウマ血清、1%非必須アミノ酸を含むDMEM)。実験当日に、細胞をハンクス緩衝液で洗浄し、次いで、0.1%BSAおよび20mM HEPESを加えたハンクス緩衝液の存在下で、37℃にて1時間インキュベートする。次いで、依然として0.1%BSAおよび20mM HEPESの存在下で、緩衝液を新鮮な緩衝液で置換する。次いで細胞を、多様な濃度の試験中の生成物とともにおよび3×10-9M GHRHとともに、CO2インキュベーター中で、37℃にて3時間インキュベートする。供給業者の指示に従ってELISA Rat Growth Hormone Biotrack Enzymeimmunoassayキット(Amersham RPN2561)またはMouse/Rat GH ELISAキット(DSL−10−72100)を使用することによって、培地に放出されるGHを測定する。本発明の化合物は、10-11から10-6Mの範囲の濃度で、GHの放出を阻害し、実施例5の化合物は、1.3nMのIC50値を有する。
本発明の化合物はまた、腫瘍に関する臨床報告でインビトロ試験から示される用に、GH分泌性ヒト下垂体腺腫細胞からのGH放出の阻害活性を示す。試験は、ヒト腫瘍生検を使用することによって実行し、可変量の試験中の化合物の存在下で、刺激を受けていない細胞から産生されるGHを、供給業者の指示に従ってELISA hGH−EASIAキット(biosource KAP1081)を使用することによって、測定する。ソマトスタチンおよび類似体の作用に感受性がある腫瘍において、本発明の化合物は、10-10から10-6Mの範囲の濃度で、好ましくは10nMの濃度で、GH産生を半減させる。
本発明の化合物は、ネンブタールの投与によって刺激されたGHの放出を、インビボで阻害する。化合物を、雄ラット(CD、Harlan Italy)に、種々の用量で皮下投与する。ネンブタール(60mg/kg)の腹腔内投与を用いて動物を麻酔させた後1時間目から、種々の時間に血液サンプルを採取し、ELISA試験を用いてホルモンレベルを測定する。本発明の化合物を、5から250μg/kgまでの用量で投与された動物において、産生されたGHレベルの減少が見られた。実施例1の化合物は、5μg/kgの用量では、投与後6時間目に測定されたGHの放出を55%減じ、125μg/kgの用量では、投与後24時間目でもなおGHの減少を測定することができる。
本発明の化合物はまた、ラットにおいて、非常に良好な薬物動態プロフィールを示す。薬物動態プロフィールは、化合物を雄ラット(CD、Sprague Dawley、200〜250g)に1mg/kgの用量で皮下投与することによって測定した。投与後72時間まで、種々の時間に血液サンプルを採取した。試験中の化合物の濃度を、別々の血漿サンプルにおいてLC−MS/MS分析法を用いて測定し、その値は、ノンコンパートメントモデルに従って、ソフトウェア「Kinetica」を使用して処理した。以下の表に、実施例1の化合物を用いて得られた主要な薬物動態パラメータを、ソマトスタチンの別の安定な類似体であり、現在臨床開発段階中のパシレオチドを用いて得られたものと比較して報告する(パシレオチドは、文献(例えば、特許文献1)に記載されている方法に従うことによって調製された)。
