本願で記載される薬剤組成物には、ここで説明する少なくとも一種の化合物と、少なくとも一種の薬剤利用可能な賦形剤(例えば、薬剤利用できるキャリアまたは希釈剤)が含まれる。好適には、想定範囲内の薬剤組成物は、ここで解説する化合物を、AD、痴呆症、または他の神経変性疾病を治療するのに十分である量で含む。
本発明は、アミロイド−ベータ−42ペプチド(Aβ42ペプチド)と関連する疾病の症状を治療または緩和する方法を提供する。この方法は、対象者に式(I)の化合物を投与するステップを含む。対象の疾病にはアルツハイマー病、痴呆症、および虚血性卒中やパーキンソン病のごとき他の神経変性疾病が含まれる。
ここで説明する化合物は従来方法により調製できる。さらに、ここで説明する化合物はスキーム1からスキーム2で示される反応順序に従って調製できる。さらに、特定の塩基、試薬、溶媒和物、結合剤、等々が言及されている以下のスキームでは、知られている他の塩基、試薬、溶媒和物、結合剤、等々も使用可能であり、本発明の範囲に含まれる。本分野で知られているように利用される、例えば反応温度及び/又は反応時間等の反応条件の改変も本発明の範囲に含まれる。これらスキームで使用される化合物の全ての立体異性体もまた、特に例外が明記されていない限り、本発明の範囲に含まれる。
ヒトの神経細胞モデル
Aβ42の生成のためのモデルとして薬剤試験のためにヒト神経芽細胞腫SH−SY5Y細胞が利用された。これら細胞は、供給元の指示に従って37℃で95%の大気湿度、5%のCO2の条件下、10%のウシ胎児血清が補完されたダルベッコ変性イーグル培養基(Dulbecco’s modified Eagle’s medium)またはダルベッコ変性イーグル培養基/ハムF−12培養基(Ham’s F−12 medium)、100ユニット/mlのペニシリン、および100μg/mlのステプトマイシン内で培養された。典型的に、これら細胞は化合物と共に一晩培養され、続いて培養基は、以下で説明するようにAβ42の定量のために回収された。細胞毒性はMTT測定法でモニターされ、細胞損失を考慮して全ての報告データは補正された。
捕捉抗体、検出抗体、および二次抗体、並びにAβ42の標準純化調製物がシグマオールドリッチから得られた。細胞は化合物の存在下または不在下で24時間培養され、調節された培養基はsELISAに供された。
認知における改善を試験するのに多用されるラット認知モデルにより、薬剤の効果が試験された。すなわち、新規物体認知におけるスコポラミン誘発記憶欠損に対する効果が試験された(Ennaceur A. Delacour J. A new one−trial test for neurobiological studies of memory in rats. 1:Behavioral data. Behav Brain Res. 1988;31:47−59)。雄ラットに、ビヒクルまたは試験化合物(0、1、3、10、30、または100mg/kg体重のドネゼピルまたは化合物)が、習慣化開始前に7日間投与され、新規対象物体認知実験期間中、継続された。
薬剤処置
動物が体重に応じて異なる処置群にランダムに振り分けられる。実験動物に試験化合物が2週間、経口投与され、対照動物にはビヒクルのみが投与される。
研究の最後に、動物は最終投与の2時間後に処分され、脳サンプルが切除され、ドライアイスによって直ちに凍結される。凍結脳サンプルは、50mMのNaCl(pH10)とプロテアーゼ抑制剤を含有した3容量(w/v)の冷却された0.2%のジチルアミンにおいて均質化され、続いて、遠心分離機を使用して4℃、15000rpmにて30分間、遠心分離処理される。得られる上澄み液は可溶性分画として維持され、10%の0.5Mのトリス−HCl(pH6.8)を加えて中和される。
プラズマ内のAβレベル、CSFおよび脳組織摘出物が、シグマ(抗アミロイドペプチドβ、裂分部位42、A1976)からの抗Aβ42抗体を使用してELISAにより決定される。
脳組織摘出物のAβ−42レベルはELISAによって決定された。モノクローナル抗βアミロイドクローンBAM−10モノクローナル抗体(シグマ、A3981)が1:1000にコーティング緩衝剤により希釈され、1.5μg/μLの実験用濃度が得られた。ウェル(凹部)あたり100μLのこの溶液は16から18時間、4℃にて96ウェルイミュノプレート(NUNC)内でコーティングされた。プレートは230μLのウォッシュ緩衝液で3回洗浄された。ウェルは150μLのブロック緩衝液で1時間ブロックされた。プレートは230μLのウォッシュ緩衝液で3回洗浄された。サンプルである標準(2500−1.1ng/ml)とブランクが適したウェルに加えられ、2時間穏やかに揺籃されながら培養された。続いてプレートは230μLのウォッシュ緩衝液で3回洗浄された。二次抗体(抗アミロイドペプチド、裂分部位42、シグマA1976)が1%のBSAで1:1000に希釈され、1.25μg/μLの実験用濃度が得られた。この100μLがウェル当たりに追加され、2時間穏やかに揺籃されながら培養された。プレートは230μLの洗浄緩衝液で3回洗浄された。100μLの検出抗体である抗−ラビットIgGの全分子HRP抱合体(1%のBSAで1:1000に希釈されたシグマA6154)がウェルに加えられ、2時間穏やかに揺籃されながら培養された。プレートは230μLのウォッシュ緩衝液により3回洗浄され、100μLのストレパビジンHRP(1%BSAにより1:200に希釈)による洗浄が続いた。プレートは230μLのウォッシュ緩衝液で3回洗浄され、100μLのTMB/H2O2基剤が加えられ、20分間培養された。反応物は50μLの2N H2SO4を加えてトップ蒸留処理され、吸光度がマイクロプレートリーダ(バイオテック社)で450/570mmにて測定された。
モーリス水迷路は認知試験に普通に使用される(F’Hooge R, De DeynPP.Applications of the Morris water maze in the study of learning and memory. Brain Res Brain Res Rev. 2001;36:60−90)。雄のウィスタラットが研究に使用される。水迷路は、水(24±2℃)で満たされた1.8m径、0.6m高の円形タンクである。16cm径のプラットフォームが、4想像象限の1つの中心で水面下1.0cmに置かれる。これは全てのラットで同じ条件である。学習実験に先立って化合物9が5日間投与され、学習実験中に継続された。学習実験中、化合物9が実験の60分前に投与された。ドネペジルは50分間の学習実験に投与された。スコポラミンは30分間の学習実験に投与された。ラットは徐々に降下され、まず足が水中に浸けられた。ラットはプラットフォームを捜して60秒間泳がされた。この時間中にプラットフォームが見つけられたら実験は停止され、ラットはプラットフォーム上に30秒間滞在するのを許され、迷路から取り出された。プラットフォームが60秒の実験中に見つけられなければ、ラットは手により視覚的手掛かりに面してプラットフォーム上に置かれ、プラットフォーム上に30秒間滞在が許され、迷路から取り出された。ラットはプラットフォームから取り出され(ラットは取り出される前に前方から研究者の手を確実に見せられる)、タオルで優しく拭い乾かす。それぞれのラットは1日に4回、この実験を受けた。迷路は8箇所の開始点を有する。1日目と3日目に、ラットは第1、第3、第5、第7の開始点から開始した。2日目と4日目にはラットは第2、第4、第6、第7の開始点から開始した。記憶の維持は第5日目に評価され、それぞれの動物は1回の120秒のプローブ調査を受け、その間、プラットフォームはプールから取り除かれていた。ラットは記憶維持実験に先立っては何も処置されなかった。ラットは加熱ランプの下に5分間置かれ、自身の居所に戻された。プラットフォームに到達する時間(ms)、泳ぐ速度(cm/s)および行路長(cm)が学習実験で測定された。標的象限(学習訓練中にプラットフォームが置かれた象限)で費やされた百分率時間はプローブ実験で計算された。ラットは継続観察され、ビデオモット2ソフトを使用してデータが発生された。
研究は生後6ヶ月のTg(HuApp695.K670−M671L)2576トランスジェニックおよび同齢のC57B16/SJL非トランスジェニック対照マウス(Hsiao K, Chapman P, Nilsen S, Eckman C, Harigaya Y, et al. Correlative memory deficits, Abeta elevation, and amyloid plaques in transgenic mice, Science. 1996;274:99−102)。マウスはジャクソン研究所から取得され、コロニーが設立された。Tg2576トランスジェニックマウスは、二重スエーデン突然変異を有する人間のAPPを過剰発現している。Tg2756と対照マウスは4週間、(1)ビヒクルのみ(n=10)あるいは(2)化合物9(50mg/kg、経口投与量、n=10)で処置された。溶解性の脳Aβ−42とAβ−40が典型的な前述のELISAプロトコルを使用して測定された。

化合物の濃度を増加させつつ細胞が一晩培養された。続いて細胞培地は回収され、培地のAβ42はサンドイッチELISAにより定量された。結果を表1に示す。
化合物9は上記の方法に従ってNORT試験によって試験された。特に、化合物は、試験された全ての投与量(0から90mg/kg/一日)にて、見慣れた対象物体と新規な対象物体とを区別する能力において、説明されているように認知機能が改善することが示され、その改善は対照ドネペジル以上であった(図1および図2)。
2週間のラットの処置(治療)後、脳内の溶解性Aβ42レベル(表2)が予測され、表2に示されている。治療効果の低下を暗示している、このペプチドのレベルの化合物による投与量が関与した減少が存在した。
モリス水迷路研究の結果(この方法で提供)は表3で示されている。改善認知の程度は動物による標的象限への到達時間により計られる。ビヒクルで治療された群の標的への到達時間は、1日目、2日目、3日目および4日目のスコポラミン治療群よりも大幅に短かった。ビヒクル治療群の行程距離および水泳速度は4日目でスコポラミン治療群と比較して大幅に減少した。同様に、ドネペジル治療群においてもスコポラミン治療群と比べて標的に対する到達時間と行程距離の大幅な短縮が2日目、3日目および4日目に観察された。
4週間に亘った化合物9(50mg/kg/日、経口)によるTg2576マウスの治療で、溶解性Aβ−42とAβ−40の脳レベルはそれぞれ22%と23%減少した。この減少は、アルツハイマー病に関連する2つの発病性ペプチドを低減させるこの化合物の性能を証明しており、この化合物の治療効果を暗示する。
