Synthesis and Anticancer Activities of Water Soluble Schiff Base Metal Complexes

Abstract

In this study, we synthesized the water-soluble Schiff Base containing S, O, N heteroatoms by the condensation reaction from 4-amino-3-hydroxynaphthalene-1-sulfonic acid and 2-hydroxy-3-methoxybenzaldehyde. In addition, Cu (II), Zn (II) and Ni (II) complexes of the ligand were synthesized and characterized by elemental analysis, magnetic susceptibility and spectroscopic techniques such as FT-IR,1H-NMR and13C-NMR. The anticancer activities of ligand and it’s three metal complexes on A549 lung cancer cell lines were evaluated. Cell viability experiments revealed that Ligand (L) and nickel (II) complex (L-Ni) did not able to inhibit A549 cell proliferation while L-Cu and L-Zn had 12 and 80 µM of IC50 values respectively. These last two complexes also induced apoptosis and suppressed cell migration on A549 cells.
