Highly cytotoxic iron(II) complexes with pentadentate pyridyl ligands as a new class of anti-tumor agents

Chem Commun (Camb). 2005 Sep 28:(36):4578-80. doi: 10.1039/b507687k. Epub 2005 Aug 19.

Abstract

The iron(II) complexes and with pentadentate pyridyl ligands are stable under physiological conditions and exhibit higher cytotoxicities toward a series of human carcinoma cell lines than cisplatin; can significantly increase intracellular oxidant levels, cleave supercoiled plasmid DNA in vitro without addition of a reductant and induce apoptotic cell death in human cervical epithelioid carcinoma cells (HeLa) as observed in flow cytometric studies.
