The inhibitory effect of the amino acid complexes of Zn(II) on the growth of Aspergillus flavus and aflatoxin B1 production

The zinc(II) complexes with amino acids as the ligands, Zn(Gln)2 (1), [Zn(Arg)2(OAc)]OAc·3H2O (2), Zn(His)2 (3), Zn(Gly)2 (4), Zn(Met)2 (5), and Zn(Cys)2 (6) (Gln = glutamine, Arg = arginine, His = histidine, Gly = glycine, Met = methionine, and Cys = cysteine) have been synthesized in aqueous solutions and characterized by elemental analysis and spectroscopic methods. In addition, the solid-state structure of 1 and 2 has been determined by single-crystal X-ray crystallography. X-ray analysis revealed that the central Zn(II) atom is six- and five- coordinated in 1 and 2, respectively. Furthermore, the antifungal activity of the synthesized complexes was investigated against the Aspergillus flavus fungus. The aqueous solutions of the zinc(II) amino acid complexes at various concentrations were added to the potato dextrose agar (PDA) medium containing spores of Aspergillus flavus, and the mixtures were then incubated at 25–30?°C for 6 days. The aflatoxin B1 produced in vitro was measured using enzyme-linked immunosorbent assay (ELISA). The increasing concentration of these complexes decreased the growth of Aspergillus flavus and aflatoxin B1 production, consequently. Furthermore, the results showed that the synthesized Zn(II) amino acid complexes are more antifungal active than the zinc(II) ion.

Zn[aminoacid]2 hybrid materials applied as heterogeneous catalysts in the synthesis of β-enaminones

Hybrid materials have seized attention from scientific community mainly as heterogenic catalysts in organic reactions on a large scale succeeding in some organic compounds with high yields. One of the most important classes of hybrid materials used for this purpose involves the complexation of Zn and aminoacids. Herein, we introduced Zn[Pro]2 and Zn[Gly]2 in the synthesis of several β-enaminones via solvent free protocol and using an ultrasound device.
