Gadolinium(III) complexes of aminophosphonates, including a novel ligand LH-4(8), have been investigated as potential contrast agents for NMR imaging. Water H-1 relaxivities at 10 and 200 MHz were determined and luminescence measurements, on Tb(III) complexes, allowed the determination of the number of coordinated H2O molecules. The complexes bound strongly to hydroxyapatite, suggesting possible targetting to bone in vivo. This was confirmed by Gd-153 tracer studies with the most favourable biodistribution in rats being shown by gadolinium(III) ethylenediamine-N,N,N',N'-tetrakis(methylenephosphonate).
