Abstract: The goal of this research was to investigate the potential of newly synthesized gold complex trichloro(2,4,6-trimethylpyridine)Au(III) as an anticancer agent. The gold(III) complex was synthesized and grafted on nanoporous silica, MCM-41, to produce AuCl3@PF-MCM-41 (AuCl3 grafted on pyridine-functionalized MCM-41). The toxicity of trichloro(2,4,6-trimethylpyridine)Au(III) and AuCl3@PF-MCM-41 in Saccharomyces cerevisiae (as a model system) was studied. The gold(III) complex showed a mid cytotoxic effect on yeast viability. Using the drug delivery system, nanoporous MCM-41, the gold(III) complex became a strong inhibitor for growth of yeast cells at a very low concentration. Furthermore, the animal tests revealed a high uptake of AuCl3@PF-MCM-41 in tumor cells. The stability of the compound was confirmed in human serum.
