      Two Schiff base ligands FT1 and FT2 and their Cu(II) complexes were synthesized and characterizedby 1H NMR, ESI-MS, IR, UV-Visible, Fluorescence spectroscopy, EPR and single-crystal X-raydiffraction studies. FT1 crystallizes in the triclinic system while FT2 in the orthorhombic. The DNA cleavageactivity of Cu(II) complexes was studied using plasmid pBR322 DNA by gel electrophoresis. All compoundscleave DNA on photoirradiation by oxidative mechanism.

      Two Schiff base ligands FT1 and FT2 and their Cu(II) complexes were synthesized and characterized by 1H NMR, ESI-MS, IR, UV-Visible, Fluorescence spectroscopy, EPR and single-crystal X-ray diffraction studies. Both the Cu(II) complexes of indole thiocarbohydrazones are shown to cleave plasmid pBR322 DNA by oxidative mechanism.
