Synthesis and Character cterization of Schiff Base Co^II, Ni^II and Cu^II Complexes derived from 2-Hydroxy-1-naphthaldehyde and Ethyle enediamine

New Co^II, Ni^II and Cu^II complex ha as been synthesized and characterized by elemental annalysis, UV-Vis, FT-IR and thermal analysis Binding of this is Co^II, Ni^II and Cu^II complex with calf thymus DNA w was investigated by UV-Visible absorption, fluorescence sp pectroscopy techniques. The intrinsic binding constan nts Kb of complex with CT-DNA obtained from UV-Vis a absorption studies. Further, the in vitro cytotoxic e effect of the complexes examined on cancerous cell line, succh as human breast cancer cells (MCF-7).
