Photodynamic Effect in Near‐IR Light by a Photocytotoxic Iron(III) Cellular Imaging Agent

A red light for cancer cells: an iron(III) complex (1, see picture) that contains an anthracenyl fluorophore moiety and a catecholate ligand is a potent, metal-based PDT agent that efficiently photocleaves DNA in near-infrared light, has significant nuclear uptake, and high photocytotoxicity in red light by an apoptotic pathway in HeLa and MCF-7 cancer cells.
