2μMの組換えタウタンパク質と15μMのヘパリンを30mMのTris(pH7.5)緩衝液で、37℃で一晩インキュベートすることにより繊維化させた。次に、30mMのTris緩衝液(pH7.5)で希釈した0.04μMの組換えタウタンパク質と試験化合物(1%のDMSOを含む)を1時間反応させた。飽和曲線を作成し、Prismソフトウェア(GraphPad)を使用し、パラメーター推定法を使用して蛍光測定データを読み取った。各試験化合物のKd値を測定した。表Aには、例示的な試験化合物のKd値を示した。
前記記載に従い、体外での蛍光競合結合テストを実施した1。アルツハイマー病患者の側頭皮質に由来する凍結組織を、プロテアーゼ阻害剤混合物(cOmpleteTM、EDTAフリー、Roche)を含む50mMのTris-HCl緩衝液(pH7.4)の中で均質化させ、分析のために-80℃で保存した。放射性リガンドの同種または異種遮断への結合を測定するために、PBB3の非存在下または非標識下で、これらのホモジネート(100μg組織)を5nMの[11C]PBB3(モル放射能:100~150GBq/mol)を10-11~10-6Mの濃度で、10%エタノールを含むTris-HCl緩衝液の中で、pH7.4で、室温で30分間インキュベートした。5×10-7M PBB3の存在下で[11C]PBB3の非特異的結合を測定した。サンプルは1回のみ測定し、特異的放射性リガンド結合はpmol/g組織で測定した。非線形回帰を使用して阻害定数(Ki)と変位率を測定し、GraphPad Prism 6.0(GraphPad Software)を使用し、Cheng-Prusoff方程式により、濃度結合グラフに適合する単位点および2部位結合モデルを取得し、モデル選択のためのF検定を行った。単一サイトの相同ブロッキングモデルでは、当該函数を使用して、相同競合結合から解離定数(Kd)を計算した:
Kd=Ki=IC50-放射性リガンド
ここで、IC50と[放射性リガンド]は、それぞれ50%の阻害と放射性リガンド濃度を誘発する競合者の濃度を表す。[11C]PBB3及び非標識PBB3の実験は、化合物の光変換を回避するために、薄暗い条件で行われた。表Bは、例示的な試験化合物のKi値を表した。

前記に記載の通り、覚醒している動物のリアルタイムイメージングは、2光子レーザー走査顕微鏡を使用して実行した2。頭蓋窓を配置するために、生後6~13か月のrTg4510タウトランスジェニックマウス3を、空気、酸素、及びイソフルラン(誘導用に3~5%、手術用に2%を使用)の混合物を含むマスクで麻酔し、「Seylaz-Tomita法」4に従って、頭蓋窓(直径3~4mm)を左体性感覚皮質に配置し、中心をブレグマの1.8mm、ブレグマの外側の2.5mmにした。頭蓋骨の窓の上の中心にある直径7mmの穴を通して、カスタマイズされた金属プレートを頭蓋骨に固定した。Takuwa et al.5に詳述されている慢性頭蓋窓を製造する方法を使用した。すべてのイメージング実験は、頭蓋窓の製造から少なくとも2週間後に実行された。血管及び病理学的タウ含有物は、それぞれ、スルホローダミン101(SR101; MP Biomedicals、Irvine、CA)及びPBB3又は試験化合物で蛍光標識された。SR101を塩水に5mMまで溶解させ、PBB3又は試験化合物をDMSO(和光):塩水=1:1溶液に0.05%(W/V)まで溶解させた。イメージング実験を開始する直前に、2種の溶液100μLをマウスの腹腔内に注射した。注:同じ実験グループ(それぞれ、試験化合物及びPBB3実験からなる)の実験は、同じrTg4510タウトランスジェニックマウスに約1週間の間隔で順次的に実施された。イメージング期間では、覚醒している動物を前記に記載のカスタマイズされた装置に配置した5。簡単に言うと、動物のヘッドの金属板をカスタマイズされた立体定位固定装置にねじ込み、次に、空気流を利用して浮かんでいる発泡スチロールのボールの上に動物を置き、動物をボールの上で自由に運動できるようにし、動物のヘッドを装置に固定した。ヘッドを固定した後、励起波長900nmの2光子レーザー走査顕微鏡(TCS-SP5 MP、Leica Microsystems GmbH、Wetzlar、ドイツ)でリアルタイムのイメージングを実行した。ビームスプリッター(560/10nm)で発光信号を分離し、同時にSR101(610/75nm)及びPBB3(525/50nm)のバンドパスフィルターで検出した。単一の画像平面は1024×1024ピクセルで構成され、面内ピクセルサイズは0.45μmであった。ボリューム画像が得られ、その最大深度は、皮質表面から0.3~0.5mmで、z方向は2.5μmであった。同じrTg4510タウトランスジェニックマウスで実施された各グループの実験は、対照(PBB3)実験の結果に基づいて、相応する豊富で明確な蛍光標識されたタウ病理の参照画像平面を示し、比較のために元のボリューム画像から関連するすべての実験の同等物を抽出した。各イメージング結果では、ImageJによってランダムに選択した10個の蛍光標識された病態の蛍光強度を測定し、バックグラウンド正規化後に平均値を計算した。ランダムに選択された10個の領域における蛍光強度の平均によって各画像のバックグラウンド強度を取得したことに注意されたい。図1は、PBB3と比較した化合物J及び化合物Wの2光子レーザー蛍光顕微鏡の結果を示している。図2は、PBB3と比較した化合物Jの2光子イメージングをrTg4510マウスに使用して生成させた画像(上)、及び経時的な緑色蛍光シグナルの定量化(下)を示している。
