Özet

In this study [1-(4-{[(3-hydroxynaphthalen-2-yl)methylidene]amino}phenyl)ethan-1- one (B-1 ligand) were synthesized from the reaction of 2-hydroxy-1-naphthaldehyde with 4-amino-acetophenone. Following that 1-(N-{4-[(1)-1-({6-[(Z)-[1-(4-{[(3- hydroxynaphthalen-2-yl) methylidene]amino}phenyl) ethylidene]amino]pyridine2- yl}imino)ethyl]phenyl}carboximidoyl)naphthalen-2-ol (L-1 ligand) were synthesized from the reaction of 2,6-diamino pyridine with B-1 ligand. Using this Schiff base ligand Cu(II), Fe(II) and Pd(II) complexes were prepared. The structure of the ligand and its complexes were determined by H-1 NMR, FTIR, UV-Vis, elemental analysis, thermal analyses and magnetic susceptibility spectral data. Further, DNA binding properties of the ligand and its metal complexes were investigated and docking studies were carried out. As a result ligands and copper complex showed DNA binding activity and an increase with H2O2. According to these results it can be suggested that these compounds are very suitable drug candidates.
