A series of ternary metal(II) complexes M(phen)(edda); 1a (Cu), 1b (Co), 1c (Zn), 1d (Ni); H2edda = N,N′-ethylenediaminediacetic acid} of N,N′-ethylene-bridged diglycine and 1,10-phenanthroline were synthesized and characterized by elemental analysis, FTIR, UV-visible spectroscopy and magnetic susceptibility measurement. The interaction of these complexes with DNA was investigated using CD and EPR spectroscopy. MTT assay results of 1a–1c, screened on MCF-7 cancer cell lines, show that synergy between the metal and ligands results in significant enhancement of their antiproliferative properties. Preliminary results from apoptosis and cell cycle analyses with flow cytometry are reported. 1c seems to be able to induce cell cycle arrest at G0/G1. The crystal structure of 1a is also included.
