series of complexes was synthesized in order to study the effect of hydrophilic phosphodiester groups on albumin binding, relaxivity, and blood half-life in rats. Thus, compound 11a, a diethylenetriaminepentaacetato aquo gadolinium(III) (Gd-DTPA) derivative with an octyl substituent, was synthesized and compared to 5b, the analogous octyl derivative containing a phosphodiester linkage between the gadolinium
