The tri-dentate Schiff base ligand 3-(2-hydroxyethylimino)-1-phenylbut-1-en-1-ol produced the tetra-nuclear Cu(II) distorted cubane complex which contain Cu4O4 core, upon reaction with Cu(II)acetate. The complex was structurally characterized by X-ray crystallography. The kinetics and mechanism of the oxidation of 3, 5-DTBCH2 catalyzed by [CuL]4 complex, were studied at four different temperatures from 283 to 313K by UV-Vis spectroscopy. The main mode of binding of the complexes with DNA was intercalation. The interaction between [CuL]4 complex and bovine serum albumin (BSA) was studied by UV-Vis, fluorescence and synchronous fluorescence spectroscopic techniques. Theoretical docking studies were performed to further investigate the DNA and BSA binding interactions.
