Description
200~800nmの波長域における医薬品の吸光度スペクトルを、Lambda(ラムダ)20紫外可視(UV/Vis)分光光度計(パーキンエルマー、本社:米国マサチューセッツ州ウォルサム)を用いて、100%ジメチルスルホキシド(DMSO)、無水メタノール(MeOH)及び蒸留/脱イオン水(ddH2O)中で測定した。次に、定常蛍光測定器(フォトンテクノロジーインターナショナル、本社:米国ニュージャージー州バーミングハム)で蛍光発光スペクトルの収集に使う励起波長として、最大吸光度の波長を使用した。
オスのSprague-Dawleyラットから様々な神経を採取した。組織を灌流によって固定し、10%中性緩衝ホルマリンで固定後処理を行った。固定後処理の後、リン酸緩衝生理食塩水(PBS)中に作成した20%スクロース溶液に組織を入れて凍結防止した。次に、神経をOCTメディア内でメタノールとドライアイスを用いて急速冷凍した。一部のケースでは、神経をOCTメディア内で鉛直に保つための補助としてポリフッ化ビニリデン膜を使用した。Leicaミクロトームで5~10ミクロンの切片をスライスし、-80℃の冷凍庫に保管してから医薬品(1)~(5)で染色した。
小動物向け市販システム:マルチスペクトルイメージングカメラ(ニュアンス、本社:米国マサチューセッツ州ウォーバーン、CRI)を備えた蛍光立体顕微鏡(SteREO Lumar V12、カールツァイス社、本社:米国ニューヨーク州ソーンウッド)を1~5秒の露光時間で使用した。中心波長が406nmでバンド幅が15nmのフィルタを用いてフルオロフォアの励起を行った。付属のマルチスペクトルカメラを用い、蛍光発光スペクトルを420~720nmの波長域で10nm刻みで記録した。或いは、550ロングパスフィルタを備えた発光フィルタも以前に使用している(マルチスペクトルカメラは不使用)。
静注による全身投与のため、次に示す賦形剤を用いて造影剤を調合した:5~15%のプロピレングリコール(フィッシャーP355-1)、5~30%の2-ヒドロキシプロピル-β-シクロデキストリン(2-HPβCD、シグマH5784)及び70~90%の蒸留/脱イオン水。一部のケースではPEG-300とDMSOも添加した。静脈内投与製剤は1Mの塩酸を用いて最終pHを7.4にした。式I(f)の化合物がこの製剤中に完全に溶解したことを、(1)微粒子がないかどうかの目視検査、(2)遠心分離(12,000gで5分間)後の観察、(3)生理的に適切な緩衝剤(例えば、セーレンセンのリン酸緩衝液)に溶解させた後の目視検査とUV/Vis分析及び(4)動的光散乱を用いた沈殿と粒径の評価を用いて確認した。
様々な製剤をいくつか試験した。これには以下が含まれるが、これらには限定されない。
製剤1:10%のPEG-300、20%のPG、0.4%のカーボポール、69.6%の水;
製剤2:10%のDMSO、20%のPEG-800、20%のPG、0.1%のポリソルベート-80、49.9%の水;
製剤3:30%のPEG-300、5%のDMSO、10%のPVA、55%の水;
製剤4:30%のPEG-300、10%のPVA、60%の水;
製剤5:30%のPEG-300、5%のDMSO、30%のプルロニックF-68、0.1%のポリソルベート-80、34.9%の水;
製剤6:20%のPEG-300、10%のPG、5%のPVP、5%のラウロカプラム、60%の水;
製剤7:20%のPEG-300、10%のPG、5%のPVP、5%のラウロカプラム、5%のEtOH、5%のオレイン酸、10%のTween-80、40%の水;
ただし、PVA=ポリビニルアルコール、PVP=ポリビニルピロリドン、PEG=ポリエチレングリコールである。
