Abstract
We prepared a Pt(iv)-prodrug, which under cancer specific conditions (elevated concentration of reactive oxygen species, ROS) releases a DNA-binding drug oxaliplatin as well as ROS-amplifying drugs p-quinone methide and N-alkylferrocenium. Due to the concerted action of these components, an excellent anticancer effect was achieved: IC50 = 0.4 ± 0.1 μM for human ovarian carcinoma A2780 cells. Importantly, the prodrug was found to be 45-fold less toxic to normal cells (HDFa).
