DTPA-bispicolineamideligands, Gadolinium complexes comprising DTPA-bispicolineamide ligands and method for the preparation thereof

摘要

The present invention is represented by DTPA- bis ( picolinic amide) ligand represented by Formula 1 and Formula 2 which relates to a gadolinium complex of a DTPA- bis ( picolinic amide) ligand , the invention DTPA- bis ( picolinic amide) ligand since it contains both the end of the term to two or more pyridine derivatives metals ( gadolinium , etc.) has the advantage that can be fixed .
