    • Complex 6 is nuclease inactive under similar experimental conditions. The cleavage efficiency of 3 with a thiophenyl group is found to be more than 1 having a thiomethyl moiety. This may be related to the greater binding ability of 3 to DNA than 1. Complex 5 with an ONO-donor Schiff base exhibits chemical nuclease activity. Mechanistic investigations reveal minor groove binding of the complexes and possible involvement of hydroxyl radical or reactive copper-oxo species in the cleavage reactions as the complexes do not show any significant DNA cleavage activity in the presence of inhibiting reagents such as DMSO. mannitol, ethanol, and the minor groove binder distamycim.
