A new series of bifunctional chelating agents useful for attaching metal ions to proteins, polypeptides and other polymers and methods for their preparation are described. These reagents are unique in their ability to bind a variety of metal ions and to yield a high metal ion concentration per protein molecule. Using these methods polymeric analogs of these bifunctional chelating agents called Starburst ligands can also be obtained. Protein metal chelates thus obtained will have useful radiophysical, chemical, fluorescent, photochemical and magnetic properties suitable for biomedical applications.
本文描述了一系列新的双功能螯合剂,可用于将金属离子连接到蛋白质、多肽和其他聚合物上,并介绍了它们的制备方法。这些试剂在其能够结合多种金属离子并产生高金属离子浓度的蛋白质分子方面是独特的。使用这些方法,还可以获得这些双功能螯合剂的聚合物类似物,称为星形配体。因此,获得的蛋白质金属螯合物将具有适用于生物医学应用的有用的辐射物理、化学、荧光、光化学和磁性特性。
