Abstract
Gold(III) complexes of the type [(DACH)AuCl2]Cl, derived from sodium tetrachloroaurate(III) dihydrate NaAuCl4·2H 2O, where DACH is diaminocyclohexane, have been synthesized. These potential metallodrug compounds were characterized using various spectroscopic and analytical techniques, including elemental analysis, UV-Vis, infrared spectroscopy, solution as well as solid NMR spectroscopy and X-ray crystallography. The potential of the synthesized gold(III) complexes as anti-cancer agents was investigated by measuring some relevant physicochemical and biochemical properties, such as the stability of the Au-N bonds by vibrational stretching from far-IR as well as cytotoxicity and the stomach cancer cell inhibiting effect. The solid-state 13C NMR chemical shift shows that the ligand is strongly bound to the gold(III) center via N atoms. An X-ray crystallography study of the complexes shows that the cyclohexyl ring adopts a chair conformation and the gold coordination sphere adopts a distorted square planar geometry. The cis isomer in solution showed higher activity towards the inhibitory effect of human cancer cell lines such as prostate cancer (PC-3) and gastric carcinoma (SGC-7901) than that of the trans isomer. The cytotoxicity of the cis isomer complex has also been estimated in PC-3 and SGC-7901 cells.
