  Cu(I) complexes of bis(methyl)(thia/selena) salen ligands: Synthesis, characterization, redox behavior and DNA binding studies

  摘要：

  Mononuclear cuprous complexes 1 and 2, [{CH3E(o-C6H4)CH = NCH2}(2)Cu]ClO4; E = S/Se, have been synthesized by the reaction of bis(methyl)(thia/selena) salen ligands and [Cu(CH3CN)(4)]ClO4. Both the products were characterized by elemental analysis, ESI-MS, FT-IR, H-1/C-13/77Se NMR, and cyclic voltammetry. The complexes possess tetrahedral geometry around metal center with the N2S2/N2Se2 coordination core. Cyclic voltammograms of complexes I and 2 displayed reversible anodic waves at E-1/2 = + 0.08 V and + 0.10 V, respectively, corresponding to the Cu(I)/Cu(II) redox couple. DNA binding studies of both the complexes were performed applying absorbance, fluorescence and molecular docking techniques. Competitive binding experiment of complexes with ctDNA against ethidium bromide is performed to predict the mode of binding. The results indicate the groove binding mode of complexes 1 and 2 to DNA. The binding constants revealed the strong binding affinity of complexes towards ct-DNA. (C) 2016 Elsevier B.V. All rights reserved.

DFT calculations revealed that the cleavage of Se–C(alkyl) bonds occurred possibly viaSN2 mechanism instead of a sequence of oxidative addition and reductive elimination reactions.
