A new type of dendritic molecules, Gd-DTPA derivatives, which work as a functionalized ligand coordinating gadolinium(III) ion at the center of their frameworks with different terminal moieties on the molecular surfaces, was readily synthesized with high yield. The structures were established by H-1, C-13 NMR, and mass spectral studies. In vitro studies showed them to have enhanced r(1) value in albumin medium and good potentiality as MRI contrast agent.
