Abstract
Description
本発明は、2002年4月11日に出願された米国特許仮出願シリアル番号60/372,500に基づく優先権を主張し、これを完全に本明細書中に援用する。
本発明は、イメージングプローブ、診断薬、および造影剤として有用なフッ化バイオポリマーおよびポリマー誘導体、ならびに、前記フッ化バイオポリマー類およびポリマー類を用いたイメージング方法に関する。
ヒアルロン酸(またはヒアルロナン、HA)は、グルコサミノグリカン類系のバイオポリマーの1→3−β結合したN−アセチル−D−グルコサミン−1→4−β−D−グルクロン酸の高分子量コポリマーであり、特異なレオロジー特性を有する。その生理作用としては、細胞の潤滑および保護、細胞の構造的完全性の維持、ならびに、細胞内および細胞への輸送が挙げられる。HAは細胞外マトリックス(ECM)内に見られ、その器官および構造内で不可欠な役目を果たす。ヒアルロナンは、組織の発達、再生および再構成における細胞増殖および移動、ならびに組織内の進行中の悪性腫瘍の侵襲に影響を与える(例えば、B.P.Toole、S.D.Banerjeeの、Oligosaccharides reactive with hyaluronan−binding protein, monoclonal antibodies recognizing hyaluronan−binding protein,and use in cancer therapy、米国特許第5,902,795号、1999年;Current Communications in Molecular Biologyに記載のS.Kumar、D.West、D.B.Rifkin、M.Klagsburn(編集)、 Hyaluronic acid and its degradation products modulate angiogenesis in vivo and in vitro、Angiogenesis:Mechanism and Pathobiology, Cold Spring Harbor Laboratory,Cold Spring Harbor,New York、90〜94頁、1987年を参照)。
γ−PGAはポリアニオン性であるため水溶性が高く、共溶質による溶解構造の変形が可能である。異なるpH値に反応して構造変化を受けるPGAの性質のため、標的を絞った送達に影響する可能性が生じる。γ−PGAは、高分子であり、溶液構造が異なることを特徴とし、生体適合性、生体分解性(グルタミン酸モノマーに生体分解する)、無毒性、および無免疫原性という性質を持つ。γ−PGAはまた、粘膜付着性が高く、これは小腸粘膜または結腸粘膜内での薬物送達手段として、部位特異的な局所化をするために重要な特性である。
多用途の非侵襲性診断用プローブはかなりの需要があり、非侵襲イメージング用途におけるフッ素の診断学的価値には、特に関心が寄せられている。無極性酸素は、19F核にスピン格子緩和速度(R1)および化学シフトに関連した常磁性緩和効果を与える。この効果は、O2(pO2)の分圧に比例する。したがって19F NMRは、細胞内および他の生体構造内の特定のフッ素化種の酸素環境を、厳密に調査することができる。
本発明は、イメージングプローブ、診断薬、および造影剤として有用な、フッ化バイオポリマーおよびポリマー誘導体類(式I〜XX)に関する。さらに、本発明は、式I〜XXの化合物を用いたイメージング方法に関する。
本発明の改良されたバイオポリマー類を含む新規組成物は、一般式IからVIIIの化合物を包含し、本発明はそれらのバイオ材料、イメージングプローブ、診断ツール、および造影剤としての使用を含む。
式IIにおいて、R1=H、X;R2=H、X;R3=H、OY、OX、NHXである。
式IIIにおいて、R1=H、X;R2=H、X;R3=H、Y、Xである。
式Vにおいて、R1=H、X;R2=H、X;R3=CO2H、CO2X、CH2X、CH2NHX;R4=H、SO3H、X;R5=H、SO3H、X;R6=H、X;R7=COCH3、COX、Xである。
式VIIIにおいてR1=H、X;R2=H、X;R3=CO2H、CO2X、CH2X、CH2NHX;R4=H、X;R5=H、X;R6=H、X;R7=H、X;R8=COCH3、COX、Xである。
Yは、モノ−、ジ−、オリゴ−、またはポリサッカリドを含むサッカリド分枝残基、モノ−、ジ−、オリゴ−、またはポリサッカリドを含むフッ化サッカリド分枝残基である。
Yは、モノ−、ジ−、オリゴ−、またはポリサッカリドを含むサッカリド分枝残基、モノ−、ジ−、オリゴ−、またはポリサッカリドを含むフッ化サッカリド分枝残基であり、

a.1つ以上の請求項1〜4記載のフッ化および/または常磁性ポリマー類を、有効量患者に投与し、
b.患者を、投与したポリマー類の堆積が期待される組織/器官のMRIにかけ、そして、
c.得られたMRI画像から組織/器官を評価する。
当業者ならば、MRIの結果を観察および/または患者の以前のMRIまたは診断用に用いられる標準的なMRI結果と比較することにより、容易に評価することが可能である。
炭水化物、ポリマー、およびタンパク質残基を含む本発明の組成物は、以下に開示するような一定のフッ素化学反応を用いて、各々の出発物質(主鎖または基質部位)をフッ素部位で処理することにより得られる。
本発明の新規なフッ素化バイオポリマー類の製造には、3つの一般的なアプローチを用いることができる。(1)低分子量のフッ素化置換基をもちいることができる(実施例に記載のように);(2)官能性ペルフルオロポリマー類のような、高分子量ポリフッ素化残基を用いることができる;および、(3)化学的または酵素を用いた処理によって、ポリマー性物質にフッ素化モノマー類を組み込むことができる。上述のアプローチにより、広範囲のフッ素置換基の種類と含有レベル(以下の実施例に記載のように、5〜40%以上)のフッ素化バイオポリマー類を製造することができ、診断用途または治療用途にあわせて調整することが可能である。最適のフッ素含有率が、診断についての感度の要求、および、プローブの生物学的または物理化学的特性、例えば、溶解度またはレセプターに結合する能力を妨害しない、最大フッ素置換の程度により、それぞれの場合により決定される。これらの検討に重要なパラメータは、フッ素置換基の種類、およびそのプローブ基体上の位置である。一般的に好適なFの含有率は、10〜40%であり、より好適には20〜40%である。
本発明の方法に使用可能な化合物は、以下の詳細な実施例に基づき、容易に入手可能な出発物質、試薬、および公知の合成方法を用い、容易に製造可能である。当業者に既知のさらなる変形もまた可能であるが、詳細には言及しない。下記の実施例は、本発明の実施を説明するものであり、その範囲を限定的するよう解釈するべきではない。
