Kinetics and Mechanism for Reduction of the Anticancer Prodrug trans,trans,trans-[PtCl2(OH)2(c-C6H11NH2)(NH3)] (JM 335) by Thiols
Reduction of the anticancer trans platinum(IV) prodrug JM335 by thiols in a moderately alkaline aqueous perchlorate medium is quite rapid and yields trans-[Pt(OH)2(c-C6H11NH2)(NH3)] as the reaction product. The mechanism of reduction involves reductive attack by thiol or thiolate on one of the mutually trans chloride ligands, leading to the formation of a chloride-bridged activated complex.The red
