Abstract
Disodium salts of the substituted dithiocarbamates (DTCs) N-cyclohexyl-N-(2-sulfonatoethyl) DTC, N-cyclohexyl-N-(3-sulfonatopropyl) DTC, and N-cyclohexyl-N-(2-hydroxy-3-sulfonatopropyl) DTC were synthesized and assessed as complexing agents for reducing organ concentrations of cadmium (Cd) in mice. At least one week after mice were given 0.03 mg of CdCl2 .cntdot. 2.5 H2O containing 1.0 .mu.Ci of 109CdCl2 ip they were treated ip with various doses of each DTC. Administration of 4.44 mmoles/kg of each analog q2dx4 produced about a 60% reduction in the whole-body Cd burdens. There was approximately a 50% reduction of renal Cd concentrations and a > 90% reduction of hepatic Cd. There was no significant effect on the Cd levels in pancreas, spleen, testes, or brain. Mobilization of organ Cd stores led to excretion of Cd prinically in the feces; treatment with 2.22 mmoles/kg of each analog qdx3 promoted a cumulative excretion of 32-40% of the administered metal. Rational design of potential Cd complexing agents is discussed with reference to the relative aqueous and lipid solubilities of the N,N-substituents on DTC congeners.
