Catecholase activity, DNA binding and cytotoxicity studies of a Cu(<scp>ii</scp>) complex of a pyridoxal schiff base: synthesis, X-ray crystal structure, spectroscopic, electrochemical and theoretical studies

Abstract

A Cu(<sc>ii</sc>) complex, [Cu(L¹H^py)Cl]₂(ClO₄)₂, of a tridentate pyridoxal Schiff base shows exceptionally high catalytic efficiency (<italic>k</italic>_cat = 3.46 × 10⁵ h⁻¹) for catecholase activity in MeOH solution, the highest value reported in literature so far.
