AB - A series of mono- and bi-metallic metal complexes (with CuII, PtII and ZnII) with substituted polypyridylligands have been prepared and their binding affinities towards quadruplex (c-Myc and human telomeric)and duplex DNA (ds26 and calf thymus) determined using fluorescent indicator displacement (FID) assaysand UV/vis spectroscopic titrations. These studies have shown that the number of aromatic rings andnumber/position of cyclic amine substituents on the ligands, play an important role in defining the DNAbinding abilities of the resulting metal complexes. We also show that bi-metallic complexes preparedusing a novel terpyridine-cyclen ligand have higher affinity towards G-quadruplex DNA as compared totheir mono-metallic counterparts. Cytotoxicity assays were carried out for all the new complexes againstan osteosarcoma cancer cell line (U2OS) as well as a normal fibroblast cell line (GM05757). Several ofthese compounds displayed cytotoxicity similar to that of cisplatin.
