INTERACTIONS OF PLATINUM AMINE COMPOUNDS WITH SULFUR-CONTAINING BIOMOLECULES AND DNA FRAGMENTS... 

To investigate the kinetics in more detail, the reaction rates of a simple pair of model compounds, [Pt(dien)X] [(X = Cl-, H2O) with GSH, GS-Me and 5 -GMP have been investigated and compared (164). The reaction products with GSH and GS-Me are shown in Fig. 10 an overview of the reactions between [Pt(dien)Cl] and GSH is presented in Scheme 2. These products are the first well-identified complexes between S-containing biomolecules and platinum amine compounds (130) and therefore are ideally suited as model compounds for kinetic studies. The results of the reactions are summarized in Table IV. In agreement with the above-mentioned hypothesis, the chloride hydrolysis is the rate-determining step in the reaction of [Pt(dien)Cl]+ with 5-GMP,...
