Decorporation of Pu and Am by tetrameric catecholylamide (CAM) ligands has been investigated in beagles and mice. Eight dogs were injected intravenously (iv) with /sup 237 +239/Pu(IV) + /sup 241/Am(III) citrate, and 30 min. later, pairs of dogs were injected iv with 3,4,3-LICAM(C), 3,4,3-LICAM(S), CaNa/sub 3/-DTPA, or each of the latter two ligands. Blood was sampled, and excreta were collected for 7 days, at which time the dogs were sacrificed and nuclide retention in liver and nonliver tissue was measured. Groups of five mice were each given /sup 238/Pu(IV) or /sup 241/Am(III) citrate iv; 3 min later a CAM ligand was injected intraperitoneally, mice were killed at 24 hr, and separated excreta and tissues were analyzed. In the dogs, average retention at 7 days of the injected Pu and Am, respectively, was as follows: 12 and 70% after treatment with a CAM ligand alone; 30 and 20% after DTPA; 12 and 20% after LICAM(S) plus DTPA; 90 and 89% without a ligand. In the mice, mean retention of the injected Pu and Am, respectively, was as follows: 14 and 66% after treatment with LICAM(C); 21 and 54% after LICAM(S); 91 and 87% without a ligand. LICAM(C) was more effective in removing Pu from liver and LICAM(S) was more effective in the skeleton. LICAM(C) is less acidic than LICAM(S), which reduces its ability to chelate Fe(III) at the pH of tubular urine, and its lesser hydrophilicity allows diversion of some ligand to the GI tract and away from the kidneys.
