    • 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,特别是镧系元素金属螯合剂,更具体地,可用作Gd(III)的螯合剂,用作治疗和诊断应用以及临床和生物医学研究应用的磁共振成像(MRI)中的造影剂。 使用开环易位聚合(ROMP)产生聚合物螯合物。 聚合物可以具有多个用于官能化的位点,允许合成多峰和靶向造影剂。 将羟基吡啶酮(HOPO)基螯合部分整合到ROMP衍生的聚合物中。 更具体地,基于HOPO的螯合部分整合成构成聚合物主链的苯并降二烯单元。 ROMP衍生的聚合物螯合剂可以在不同长度的聚合物中包含多种金属离子,特别是Gd(III)离子,以提供具有受控弛豫物质的一系列试剂。 聚合物螯合物包括那些水溶性螯合物。
