Abstract


Ruthenium(III) complexes [Ru(bphtpy)(PPh3)Cl3] (bphfpy = diphenylfuranylpyridine derivatives) were synthesized and characterized by LCMS, IR spectroscopy, elemental analysis and magnetic measurements. All the complexes were screened for their antibacterial activity in terms of minimum inhibitory concentration against two Gram-positive and three Gram-negative bacterial species. DNA binding study by absorption titration and viscosity measurement shows that complexes bind in an intercalating mode, which is also confirmed by molecular docking. All the complexes were also screened for the DNA nuclease property of pUC19 plasmid DNA. The cytotoxicity study of the synthesized complexes was performed to elucidate the LC50 values to find out the toxicity profile of the complexes.
