Özet

Three new copper(II) complexes (1-3) with general formula [Cu(HL)CH3COO] of N-salicyl-beta-amino alcohol Schiff bases containing, (S)-(+)-phenyl glycinol. (1S, 2R)-2-amino-1, 2-diphenylethanol and 1, 1, 3-triphenyl-(R)-(+)-2-amino propanol, were synthesized. Their structures were characterized by FTIR, LCMS, magnetic moment, molar conductance and elemental analysis data. DFT calculations proposed distorted square planar geometries for the complexes. The calculated IR spectra are in good agreement with the experimental IR spectra, confirming the proposed structures. Their interactions with calf thymus DNA were investigated and their binding constants K-b were found. Gel electrophoresis reveals that all complexes display significant nuclease activity against supercoiled pentry/d-topo plasmid DNA.
