Figure 7: Structural model of the Pt adduct proposed to form in the reaction between R,S-d(G1C2G3sA4G5C6)2 (VIs) and [Pt(15NH3)2I2] (I). Nucleotides associated with different nucleic acid strands are labelled by colour-coded lettering. The platinum centre attached to both phosphorothioate sulphur and G5-N7 is indicated by the label Pt.
