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

A Cu( ii ) complex, [Cu(L ¹ H py )Cl] ₂ (ClO ₄ ) ₂ , of a tridentate pyridoxal Schiff base shows exceptionally high catalytic efficiency ( k cat = 3.46 × 10 ⁵ h ⁻¹ ) for catecholase activity in MeOH solution, the highest value reported in literature so far.
