Abstract
【選択図】図1
Description
本発明では、アルデヒドスカベンジャーは、アミノ−オキシ末端を有する分子であり得る。アミノ−オキシ官能基は極めて反応性であることが知られており、例えば、1ppmの濃度でアセトンを室温においてほぼ完全に変換することができる。
(i)医薬製剤中の遊離アミノオキシ含有賦形剤、
(ii)医薬製剤を通過させる、結合アミノキシ含有官能基を含有する固相材料、
(iii)個々の用量/QC/マイクロ/保持試料バイアルの初回分配の際に使用される分配流体経路の一部としてのカートリッジ/濾過ユニットの一部、
(iv)臨床使用の直前の分配に使用される分配流体経路の一部としてのカートリッジ/濾過ユニットの一部、
(v)放射性トレーサの製造直後に、患者用量投与のためにシリンジを充填するときに医薬製剤を通過させるカートリッジ/濾過ユニットの一部、及び/又は
(vi)臨床使用の直前に、患者用量投与のためにシリンジを充填するときに医薬製剤を通過させるカートリッジ/濾過ユニット
として提供することができる。
本発明では、医薬製剤は最終放射性医薬製剤を指すものとする。一実施形態では、医薬製剤は、哺乳動物投与に適切な形態であり、無菌で、発熱物質非含有の、毒性及び有害事象を起こす化合物を含まない、生体適合性のpH(およそpH4.0から10.5)において製剤化された製剤を意味する。このような製剤は、インビボで塞栓を引き起こし得るリスクのある微粒子を含まず、生物学的流体(例えば血液)との接触において沈降を起こさないように製剤化される。このような製剤はさらに、生物学的に適合性の賦形剤、好ましくは等張性の賦形剤だけを含有する。本発明では、医薬製剤は放射性医薬品及び溶媒を含み、各々は本明細書に記載されている。医薬製剤は、限定するものではないが、自動合成機(例えば、FASTlab(登録商標))を含む当分野で公知の任意の手段によって製造することができる。
本発明では、放射性医薬品は、インビトロ又はインビボイメージングに適切な任意の放射標識化合物を含むことができる。本発明の一実施形態では、放射標識化合物は、インビボイメージングに適切である。インビボイメージングに適切であるために、放射性医薬品は哺乳動物投与に適した形態で適切に提供され、哺乳動物対象単独をイメージングすることによって得られる画像よりも、目的の領域又は器官においてより鮮明な画像の提供を支援する。好ましい実施形態では、放射性医薬品は、陽電子放射断層撮影(PET)トレーサである。好ましい実施形態では、放射性医薬品は、18F PETトレーサである。適切な18F PETトレーサの非限定的な例としては、以下の[18F]フルシクラチド、[18F]フルテメタモール、及び[18F]GE180が挙げられるが、これらに限定されない。
本発明では、溶媒は、医薬製剤における使用に適切な、当分野において公知の任意の有機溶媒を含んでよい。好ましい実施形態では、溶媒はアルコールを含む。好ましい実施形態では、溶媒はエタノール、イソプロパノール又はバイオアルコールである。好ましい実施形態では、溶媒はエタノールである。
HPLCを使用してフルシクラチド(18F)注射液試料中のアセトアルデヒド含有量を分析する実験において、アセトアルデヒドを、AH111695を用いてUV吸収性フルシクラチド類似体AH111930に誘導化した(スキーム1)。
