Gd-Ethoxybenzyl-DTPA (Gd-EOB-DTPA) is a highly water-soluble paramagnetic contrast agent. Due to its protein binding of about 10% and its lipophilic residue, Gd-EOB-DTPA exhibits both renal (30% of the dose) and hepatobiliary (70%) excretion in rats. Despite its lipophilic character, the compound displays a low toxicity (LD50 = 7.5 mmol/kg). T1-relaxivity(More)
We have synthesized several classes of gadolinium (Gd) complexes for use as NMR contrast agents in the detection of soft-tissue calcification. Class I was made up of strongly chelated GdDTPA complexes with one carboxylate arm coupled to a phosphonate-containing molecule through an amide link. Class II complexes were formed by Gd with several(More)
2,4,6-tribromo-3-carboxyalkyl-benzamides and -carboxyalkoxy-benzamides are intensely sweet. With a recognition threshold value of about 1 mumol/l the 3-carboxyethyl compound is one of the sweetest compounds known. The intensity of the sweet taste depends upon the nature of the carboxyalkyl/carboxylalkoxy group. In respect to the acute toxicity to mice the(More)
