Abstract
The interaction of gold(I) thiomalate (AuStm)n (Myocrisin) with imidazolidine-2-selenone (SeImt) was studied in an aqueous solution at pH 7.40 using 13C NMR spectroscopy. It was found that SeImt binds more strongly to (AuStm)n than imidazolidine-2-thione and its derivatives as determined by 13C NMR spectroscopy. SeImt reacts differently with Au(Stm)2-, as compared to (AuStm)n. With (AuStm)n, SeImt forms a ternary complex of ImtSe-Au-Strn, releasing free Stm- to solution. Redox reaction of gold(I) to metallic gold and free thiomalate (Stm-) to disulfide (Stm)2 occurs when Au(Stm)2- reacts with SeImt.
