Abstract
本発明は、ホスホジエステラーゼ2(PDE2)の阻害剤としての新規な[1,2,4]トリアゾロ[1,5−a]ピリミジン−イル誘導体に関する。本発明はまた、この化合物を含む医薬組成物、このような化合物および組成物を調製するための方法、ならびに神経疾患および精神疾患などの、PDE2が関与する疾患の予防および治療のためのこのような化合物および組成物の使用にも関する。
Description
スキームA
本明細書において使用される際の「被験体」という用語は、治療、観察または実験の対象であるかまたは対象であった、動物、好ましくは哺乳動物、最も好ましくはヒトを指す。
本発明に係る化合物は、PDE2酵素活性、特にPDE2Aを阻害し、したがって、PDE2を発現する細胞内のcAMPまたはcGMPのレベルを上昇させる。したがって、PDE2の阻害酵素活性の阻害は、細胞中のcAMPまたはcGMPの不十分な量によって引き起こされる疾病の治療に有用であり得る。PDE2阻害剤は、cAMPまたはcGMPの量を、通常のレベルを超えて上昇させると治療効果が得られる場合にも有用であり得る。PDE2の阻害剤は、神経疾患および精神疾患を治療するのに使用され得る。
本発明は、神経疾患および精神疾患などの、PDE2の阻害が有益である疾病を予防または治療するための組成物も提供する。前記組成物は、治療的に有効な量の化合物1および薬学的に許容できる担体または希釈剤を含む。

PDE2は、主に、海馬、大脳皮質および線条体において発現され、cAMPおよびcGMPを加水分解することができる。AMPA−R輸送は、PKA(cAMPによる)またはcGKII(cGMPによる)の活性化によって調節され得る。AMPA−RのGlu1サブユニットのリン酸化は、LTD(減少)およびLTP(増加)発現および記憶の保持に重要であることが示されている。
化合物1(10%のCD+1HClに溶解された)を、スプラーグドーリーラットにp.o.(経口)投与し(180〜200g;10および40mg/kg)、2時間後、動物を断頭によって殺処分した。海馬を切開し、組織を瞬間凍結させ、−80℃で貯蔵した。
方法
放射性リガンド(Buijnsters et al.,(2014).Structure−Based Design of a Potent,Selective,and Brain Penetrating PDE2 Inhibitor with Demonstrated Target Engagement.ACS Med Chem Lett.5(9):1049−53における化合物12)として[3H]B−17a(国際公開第2013/000924号パンフレットに記載される)を用いて、エクスビボオートラジオグラフィーによって、PDE2Aの占有を評価した。雄Wistarラット(200〜250g)を、ビヒクルまたは漸増用量の[3H]B−17aの経口投与によって処理し、1時間後に殺処分した。脳を頭蓋骨から直ぐに取り出し、ドライアイスで冷却した2−メチルブタン(−40℃)中で急速に凍結させた。厚さ20μmの線条体切片を、Leica CM 3050 cryostat−microtome(van Hopplynus,Belgium)を用いて切り出し、顕微鏡スライド(SuperFrost Plus Slides,LaboNord,France)に解凍−マウント(thaw−mounted)し、使用するまで−20℃で貯蔵した。
重要な試薬
スクロース解剖緩衝液は、(mM単位で)スクロース(150)、NaCl(40)、KCl(4)、NaH2PO4.H2O(0.3)、MgCl.6H2O(7)、NaHCO3(26)、CaCl2.2H2O(0.5)、D−グルコース(10)を含有しており、これを95%のO2および5%のCO2ガス混合物で平衡化した。平衡化および記録の際に使用される人工脳脊髄液(ACSF)は、(mM単位で):NaCl(124)、KCl(2.7)、NaH2PO4.H2O(1.25)、MgSO4.7H2O(1.3)、NaHCO3(26)、CaCl2.2H2O(2)、D−グルコース(10)、アスコルビン酸(2)を含有しており、これを95%のO2および5%のCO2ガス混合物で平衡化した。CNQXおよびキヌレン酸を、それぞれ50μMおよび1mMの濃度で、ACSF中で調製した。化合物1を、ACSF中でおよび0.1%を超えない最終DMSO濃度を有するストック溶液(DMSOを含む)から新たに調製した。全ての試薬は、特に示されない限り、Sigma−Aldrich製であった。
使用した動物は、Charles River Germanyによって提供される、145〜200gの体重範囲の雄スプラーグドーリーラットであった。
標準的なプロトコルにしたがってイソフルランで麻酔した雄スプラーグドーリーラットの中間から腹側海馬から、水平な脳スライス(300μm)を得た。0.1mm/秒の速度で、低温(4℃)スクロース解剖緩衝液中で振動組織スライサ(Leica VT1200S)を用いて、スライスを切断した。切断後、スライスを、35℃で20分間平衡化させ、次に、人工脳脊髄液(ACSF)中で、室温で少なくとも1時間回復させた。3〜4つのスライスを1つの脳から準備した。
全てのデータは、60チャネルA/Dカードに連結された4チャネル刺激発生器および60チャネル増幅器ヘッドステージから構成された、MultiChannel Systems MCS GmbH(Reutlingen,Germany)から市販されているMEA設備を用いて記録した。刺激、記録および分析のためのソフトウェアは、それぞれMulti Channel Systems:MC Stim(II 2.0.0リリース)およびMC Rack(3.8.1.0リリース)から市販されているものである。実験の全ては、100μm間隔を空けた60の先端形状および60μm高さの電極からなる3次元MEA(Ayanda Biosystems,S.A.,CH−1015 Lausanne,Switzerland)を用いて行った。MEA電極は、600kΩ<インピーダンス<900kΩを有する白金で作製されている。
シナプス伝達に対する化合物1の効果を、海馬スライスにおける細胞外電場電位を記録することによって調べた。シナプス伝達が、記録電極を囲むニューロンの集団における同期されたシナプス活性を反映する細胞外電場電位の偏向(deflection)を生じ得ることは十分に確立されている。
これらの試験では、雄および雌マーシャルビーグル犬(1〜6歳)を使用した:1つの処理群につき2匹の雄および2匹の雌。脳脊髄液(CSF)を、装置を装着された意識のある動物においてニードルガイドカニューレを介して側脳室から採取した。
導入
シナプス可塑性は、多くの神経生物学的機能のための基本的機構である。海馬ならびに大脳皮質におけるシナプス強度の長く続く高度に局在した増加の形態である長期増強(LTP)は、記憶および学習のためのシナプス基質である(Cooke and Bliss,Curr Opin Investig Drugs.2005;6(1):25−34)。シナプス強度の増加および減少は、シナプス前およびシナプス後ニューロンの活性、脳内のネットワークが、記憶中の複数の項目の知覚表示(sensory representation)の設定、および適切な運動反応の生成の際にどのように機能するかに左右される。無傷の脳における、これらのシナプス調節の様々な特徴は、様々なタイプのネットワークの動作およびいくつかの異なる脳の回路系の動作に極めて重要である。したがって、LTPは、アルツハイマー病などの加齢性の精神疾患および神経変性疾患において損なわれていることが予想される(Bergado and Almaguer,Neural Plast.2002;9(4):217−32;Rowan et al.,Biochem Soc Trans.2005;33:563−7)。動物において、無傷の高度に相互接続された脳領域において麻酔下で行われる手術(procedure)は、単一パルスまたはペアドパルスで供給される低周波および高周波を有するテタヌス電気刺激後の海馬−大脳皮質回路における有効な接続性および可塑性の持続的変化を調べるための強力な手段である(Albensi et al.,Exp Neurol.2007;204:1−13)。研究は、シナプス強度の低下の発生の根底にある神経回路の理解を深め、すなわち、直接回線経路およびシナプスの弱化を媒介する特定の領域間のネットワーク接続が有する特定の生物学的標的の役割を決定するのに役立つ。手術は、病理学的形態の神経可塑性を回復させ、例えば、シナプス効力を増大することによって、LTPおよびネットワーク接続性の欠陥を改善する(これは、関連する認知および学習能力に対する有益な効果を有することが予想される)ことを目的とした薬剤の試験を可能にする(Cooke and Bliss,2005;Albensi et al.,2007)。
動物
本実験は、国際実験動物ケア評価認証協会(Association for Assessment and Accreditation of Laboratory Animal Care International)(AAALAC)の指針、および1986年11月24日の欧州委員会理事会指令(European Communities Council Directive)(86/609/EEC)に厳密にしたがって行われ、地方倫理委員会によって承認されたものである。手術の時点で170〜200gの重量の)スプラーグドーリーラットを、制御された環境条件下に維持された動物施設から到着した後、12時間の明/暗サイクル(07:00AMに点灯)で配置された換気したケージ内で集団で飼育した。
ラットに、ウレタン1.5g/kg体重の腹腔内注射で麻酔をかけた。動物を、電極の挿入のために定位固定フレームに設置し、それらの体温を、直腸プローブによって常に監視し、加熱パッドで37℃に維持した。全身麻酔を確実にするために必要に応じてウレタン(0.2〜0.5g/kg)の追加投与を行った。刺激および記録電極のために左海馬構造の位置で頭蓋骨に2つの小さい孔(直径1mm)を空けた。双極刺激電極;水平に0.125μm離れた先端を有する撚り対線のステンレス鋼ポリイミド被覆ワイヤ(MS303/13−B.PlasticsOne)を、内側貫通路(mPP)に位置決めし(AP−7.5、ML−3.8、DV−2.5)、ステンレス被覆記録電極(MS303T−2−AIU、0.008〜0.005)を、背側海馬の歯状回(DG)部位に位置決めした(AP−2.8、ML−3.8、DV−3.8)。両方の孔を通して硬膜に穿孔し、刺激および記録電極を、大脳皮質および海馬の上側層を通して、背側海馬のmPPおよびDGへと非常にゆっくりと下げた(0.2mm/分)。手術中、動物の苦しみを最小限に抑えるようにあらゆる努力をした。
電気生理学的試験の最後に、20秒間にわたる500μAの電気刺激を供給して、刺激および記録電極の先端に損傷を生じさせ、電極配置の組織学的検証のために脳を採取した。脳切片(20mm)を、光学顕微鏡を用いて調べた。不適切な電極配置を有する動物を、試験から除外した。
化合物1を、皮下(SC)投与のために10%のシクロデキストリン(CD)+1HCl+NaClに溶解させた。
各動物について、30分間にわたる安定したベースライン(テタヌス刺激前)反応を平均し、平均を、100%であるものとして正規化し、テタヌス刺激後反応データを、ベースライン平均に対して表した。テタヌス刺激後のビヒクルおよび化合物1の効果の比較を、順位に基づく一元配置反復測定分散分析(ANOVA)を用いて30分間隔で行った後、ベースライン(100%の値)に対するダネットの事後比較を行った。個別の時点での処理間の差を、両側スチューデントt検定を用いて調べた。全ての統計学的手順は、StatExact Softwareを用いて行った。
ベースラインのテタヌス刺激前のビヒクル処理された対照との間で著しい変化は見られなかったため、基底シナプス伝達は、化合物1によって影響されなかった(図8b)。LTP誘導パラダイム中、化合物1(40mg/kg)の皮下投与は、持続的な(>2時間)シナプス増強を促進した(図8b)。テタヌス刺激の完了の0〜30分後、PSA傾きは、ビヒクルレベル124±5%と比較して164±13%、p<0.05)であった。テタヌス刺激の90〜120分後の時点で、PSA振幅は依然として高かった(ビヒクルレベル116±17%と比較して179±20%、p<0.05)。同様に、刺激反応曲線の分析により、ビヒクル条件と比較してfEPSP傾きの著しい持続的増加が示された(90〜120分:ビヒクルレベル94±7%と比較して137±24%、p<0.05)(図8c)。
