Abstract

This report describes the synthesis, characterization and biological activity of a series of platinum(IV) derivatives of [Pt(1S,2S-DACH)(5,6-dimethyl-1,10-phenanthroline)] (Pt56MeSS) with non-bioactive, lipophilic and bioactive axial ligands. In an attempt to explore the anticancer activity potential of the Pt(IV) derivatives, 2D and 3D cytotoxic screening and a preliminary in vivo study were performed. The average IC50 values of the platinum(IV) derivatives ranged from 1.26 to 5.39 μM, compared with 1.24 μM for Pt56MeSS, suggesting that the axial ligands have a relatively minor effect on the potency of the compounds. Preliminary in vivo studies indicate that the platinum(IV) derivatives of Pt56MeSS are active in vivo and can reduce the tumor to a similar extent to cisplatin.
