Abstract

The N,O-donor bidentate ligands (L 1–L 7) derived from the reaction between chalcones and pyridinium salt of 2-acetyl furan were synthesized and characterized by IR and NMR spectroscopic techniques. Their complexes [1–7] of Cu(II) were synthesized and characterized by elemental analysis, magnetic measurements, TG analyses, IR and mass spectroscopy. Synthesized complexes were carried out for their biological elucidation using different biological experiments like minimum inhibitory concentration, DNA binding and cleavage study, cytotoxicity, and antiradical activity. Efficient cleavage of pUC19 DNA was observed for all the test complexes than the reference drug.

Graphical Abstract

Increase in DNA chain length and hence the relative viscosity as the complexes binds to DNA via intercalative mode and involves a strong stacking interaction between an aromatic chromophore and the DNA base pair.
