using stopped-flow and conventional UV/VIS spectrophotometry. The reactions of 1 with 2-mercaptoethanesulfonate (mesna) and 2-mercaptoethylamine (cysteamine), which is the parent compound of 2-(3-aminopropylamino)ethylphosphorothioic acid (WR2721), and of cis-[Pt(NH3)2(GSMe)2]2+ with thiosulfate have also been studied. The reactions between cisplatin and DDTC, thiourea and thiosulfate were investigated
