本出願は、米国特許仮出願第61/477,958号(2011年4月21日出願)(この記載内容は参照により本明細書中で援用される)の利益を主張する。
アミロイド沈着物および神経原繊維濃縮体(NFT;対合らせん状フィラメント PHFとしても既知である)は、種々の疾患、例えばアルツハイマー病(AD)の特質証明である。ADを有するかまたはADを有すると疑われる生存個体の脳におけるアミロイド沈着物およびNFTを画像処理する方法が、当該技術分野で必要とされている。
本明細書中で用いる場合、「ナノ粒子」という用語は、約1〜1000nmの直径を有する粒子を指す。同様に、「ナノ粒子(複数)」は、約1〜1000nmの平均直径を有する複数の粒子を指す。
本発明の開示は、β−アミロイド沈着物および/またはNFTを有するかまたは有する疑いのある生存個体における脳組織を画像処理するに際して用いるのに適している機能性磁性ナノ粒子(MNP)を提供する。本発明の機能性MNPは、アミロイド沈着物および/または神経原繊維濃縮体(NFT;対合らせん状フィラメント(PHF)としても既知)を有する神経学的組織と正常な神経学的組織との間を識別する。本発明の機能性MNPを用いて、例えばダウン症候群またはアルツハイマー病(AD)を含む疾患におけるアミロイド沈着物および/またはNFTを検出し、定量し得る。
磁性ナノ粒子に付着され得る官能基(部分)としては、β−アミロイドペプチドおよび/またはNFTの集合体との結合を提供する官能基が挙げられる。β−アミロイドペプチドおよび/またはNFTの集合体との結合を提供する、そして磁性ナノ粒子に付着され得る適切な官能基としては、2−(1−{6−[(2−ヒドロキシエチル)(メチル)アミノ]−2−ナフチル}エチリデン)マロノニトリル(HODDNP)、ならびにその類似体および誘導体が挙げられる。β−アミロイドペプチドの集合体との結合を提供する、そして磁性ナノ粒子に付着され得る適切な官能基としては、(4’−アミノフェニル)−6−ヒドロキシベンゾチアゾール(PIB−2)、ならびにその類似体および誘導体が挙げられる。
1)W−372(7−メトキシ−2(6−フルオロピリジン−3−イル)イミダゾ[2,1−b]−8−ピリジノチアゾール);
1)W−372−2;
1)W−372−3;
1)W−372−4;
1)SB−13−5;
1)SB−13−6;
本発明のナノ粒子は、一般的に、約1nm〜約1000nm、例えば、約1nm〜約10nm、約10nm〜約50nm、約50nm〜約100nm、約100nm〜約250nm、約250nm〜約500nm、約500nm〜約750nmまたは約750nm〜約1000nmの範囲の平均サイズを有する。平均直径は、いくつかの実施形態では、約10nm〜約1000nm、例えば約10nm〜約20nm、約20nm〜約40nm、約40nm〜約60nm、約60nm〜約80nm、約80nm〜約100nm、約100nm〜約200nm、約200nm〜約400nm、約400nm〜約600nm、約600nm〜約800nmまたは約800nm〜約1000nmの範囲である。
本発明の機能性MNPは、β−アミロイド沈着物および/またはNFTのほかに、治療薬、例えばADを治療するのに適した治療薬を含み得る。適切な治療薬としては、ADを処置するための作用物質が挙げられるが、この場合、このような作用物質としては、アセチルコリンエステラーゼ阻害薬、例えばアリセプト(ドネペジル)、エキセロン(リバスチグミン)、メトリフォネート、ラザダイン(ガランタミン)およびタクリン(コグネックス);非ステロイド系抗炎症薬、例えばイブプロフェンおよびインドメタシン;シクロオキシゲナーゼ−2(Cox2)阻害薬、例えばセレブレックス;モノアミンオキシダーゼ阻害薬、例えばセレギリン(エルデプリルまたはデプレニル);ならびにN−メチルD−アスパルテート(NMDA)アンタゴニスト、例えばナメンダ(メマンチン)が挙げられるが、これらに限定されない。
本発明の開示は、本発明の機能性MNPを含む組成物、例えば薬学的組成物をさらに提供する。本発明の機能性磁性ナノ粒子を含む組成物は、以下の:塩、緩衝液;pH調節剤;非イオン性洗剤;プロテアーゼ阻害薬;ヌクレアーゼ阻害薬等のうちの1つ以上を含む。
本発明の機能性MNPを用いて、β−アミロイド沈着物および/またはNFTに関連するかまたはそれに起因する疾患の、生存哺乳動物、例えばヒト、非ヒト動物、あるいは非ヒト動物モデルの脳におけるアミロイド沈着物および/またはNFTを検出し、定量し得る。本発明の機能性MNPを含む薬学的組成物は、生存哺乳動物に投与される。脳中に存在する任意のβ−アミロイド沈着物(例えば、神経原繊維濃縮体と関連し得るような凝集β−アミロイド)は、磁気共鳴画像処理(MRI)または任意の他の適切な画像処理方法を用いて可視化され得る。したがって、本発明の開示は、生存哺乳動物の脳におけるアミロイド沈着物および/またはNFTを検出し、定量する方法を提供する。当該方法は、一般的に、本発明の機能性MNPを含む診断的有効量の薬学的組成物を哺乳動物に投与すること;およびMRIにより脳組織を画像処理することを包含する。投与された機能性MNPは、脳組織中に分布され、そして凝集β−アミロイドペプチドおよび/またはNFTと結合される任意の機能性MNPがMRIを用いて画像処理され得る。結合の正常対照レベルと比較して、機能性MNPと脳組織との結合の増大は、当該哺乳動物がアルツハイマー病に罹患しているかまたは発症する危険性があることを示している。
上記のように、いくつかの実施形態では、本発明の機能性MNPは、β−アミロイド沈着物および/またはNFTを結合する機能性部分(基)のほかに、治療薬を包含し得る。このような機能性MNPは、画像処理および/またはADの治療に用いられ得る。
HODDNP共役MNP(「DNP−MNP」)
HODDNP共役MNPを、ナイーブ(無AD)ラットに、そしてADのラットモデルに投与した。データを、図1〜6に示す。
図1Aおよび1B. ナイーブ(無AD)ラットのMR(磁気共鳴)画像(T2、TR6000ミリ秒(ms)、TE 10〜120ms、12エコー)を示す。図1Aは、代表的切片の基線(プレコントラスト)MR画像を示す。図1bは、同一切片のポストコントラストMR画像を示す。基線(図1A)およびポストコントラスト(図1B)スキャンにおける体積関心領域(ROI)(ここで、ROIは海馬、皮質、中脳を含む)の定量的T2値の比較は、DNP−MNP(「HODDNP−MNP」としても言及される)による注射後のこのナイーブ動物における有意の(p>0.05)コントラスト増強を示さなかった。
PIB−2は、PIB−2のアミノ窒素を介して、エポキシ−MNPと共有的に共役される。このような方法の一例を、図8に示す。
