Synthesis, Spectroscopy, and Anticancer Activity of Two New Nanoscale Au(III) N4 Schiff Base Complexes

Abstract

Mononuclear Au(III) Schiff base complexes are synthesized by the reaction of 4-aminoantipyrine with hydrazine. The chemical structures of new Schiff bases and their Au(III) complexes are elucidated from their conductance, XRD, and spectroscopic (IR, UV-Vis, ¹H, and ¹³C NMR) data. Au(III) Ion is coordinated with the synthesized Schiff bases via four nitrogen atoms of the antipyrine and azomethine groups. Au(III) Complexes are electrolytes with three uncoordinated Cl⁻ ions, and have a square planar geometry. Their morphology is characterized by SEM and TEM methods. Cytotoxic effect of the complexes is tested against human breast cancer (MCF-7) and hepatocellular carcinoma (HepG-2) cell lines.
