Secondary antithyroid action of drugs in relation to structure.
Molecular interactions between iodine and disulfiram, clomethiazole, and tolnaftate were investigated by electron spectroscopy. Iodine forms charge transfer complexes with these molecules, with 1:1 stoichiometry and of the n-sigma type. The formation constants were compared with those obtained with antithyroid molecules. Only disulfiram appears to have any effect on the intrathyroid cycle of iodine.
