  Contrast Agents for Magnetic Resonance Imaging Synthesized with Ring-Opening Metathesis Polymerization

  摘要：

  A monomer for ring-opening metathesis polymerization (ROMP) has been developed that also functions as a portion of a GdIII chelating moiety for a magnetic resonance imaging contrast agent. An increase in per GdIII relaxivity was shown upon transition from monomer to polymer. Additionally, extremely large molecular relaxivities were achieved through incorporation of multiple GdIII ions per polymer. The nature of ROMP-derived polymers allows for functionalization of the monomer units and termini through orthogonal chemistry. This strategy is the basis for a new class of highly sensitive, targeted imaging agents.

  Polymeric chelating agents and metal chelates, particularly those of lanthanide metals and more specifically those of Gd(III), useful as contrast agents in magnetic resonance imaging (MRI) for therapeutic and diagnostic applications as well as clinical and biomedical research applications. The polymeric chelates are generated using ring-opening metathesis polymerization (ROMP). Polymers can have multiple sites for functionalization allowing for the synthesis of multimodal and targeted contrast agents. Hydroxypyridonate (HOPO)-based chelating moieties are integrated into a ROMP-derived polymer. More specifically, the HOPO-based chelating moiety is integrated into a benzonorbornadiene unit that constitutes the backbone of the polymer. The ROMP-derived polymer chelators can comprise multiple metal ions, particularly Gd(III) ions, in polymers of varying lengths to provide a series of agents with controlled relaxivites. Polymer chelates include those that are water-soluble.

  聚合螯合剂和金属螯合物，特别是镧系金属的螯合物，更具体地说是Gd（III）的螯合物，可用作磁共振成像（MRI）对比剂，用于治疗和诊断应用以及临床和生物医学研究应用。这些聚合螯合物是通过环烯烃开环聚合（ROMP）生成的。聚合物可以具有多个功能化位点，从而允许合成多模式和靶向对比剂。羟基吡啶酮（HOPO）基螯合基团被整合到ROMP衍生的聚合物中。更具体地说，HOPO基螯合基团被整合到构成聚合物骨架的苯并[2,3]环庚二烯单元中。ROMP衍生的聚合物螯合剂可以包括多个金属离子，特别是Gd（III）离子，在长度不同的聚合物中，以提供一系列具有可控松弛度的对比剂。聚合物螯合物包括水溶性的螯合物。
