We have reacted [Pt(Me4en)(D2O)2]2+ [Me4En=N,N,N’N’-tetramethylethylenediamine] with Selenomethionine (SeMet), Methionine (Met), and Methylselenocysteine (MeSeCys). When MeSeCys was reacted with [Pt(Me4en)(D2O)2]2+, we observed both stereoisomers of Se,N chelates, as well as [Pt(Me4en)(MeSeCys)Cl]+ from 1H NMR Spectroscopy; the latter formed due to the presence of Cl- in the solution. Both isomers of the chelate seemed to form proportionally to one another, not favoring a specific stereoisomer. Eventually the [Pt(Me4en)(MeSeCys)Cl]+ products became Se,N chelates. We incubated SeMet with …
