Sonoelectrochemical Synthesis of Nano Zinc(II) Complex with 2-Methyl-8-Hydroxyquinoline Ligand: a Precursor to Produce Pure Phase Nano-Sized Zinc(II) Oxide

A new zinc complex, [Zn(mq)2], (mq?=?2-methyl-8-hydroxyquinoline) was prepared via an electrochemical route from the oxidation of zinc metal in the presence of 2-methyl-8-hydroxyquinoline in a fast and facile process. The complex was fully characterized by means of NMR and IR spectra and elemental analysis. The nanostructure of the prepared compound was obtained by sonoelectrochemical process and studied by scanning electron microscopy, X-ray powder diffraction, IR spectroscopy and elemental analysis. Thermal stability of crystalline bulk and nano-size samples of the prepared compound was studied by thermal gravimetric and differential thermal analysis. The photoluminescence properties of the prepared compounds, as crystalline bulk and as nano-structure, have been investigated. The results showed a good correlation between the size and the shape of the complex particle and emission wavelength. The prepared complexes, as bulk and as nano-particles, were utilized as a precursor for preparation of ZnO nanoparticles by direct thermal decomposition at 550?°C in air. The nano-structures of ZnO were characterized by scanning electron microscopy, X-ray powder diffraction and IR spectroscopy.

Design, synthesis, and antifungal evaluation of 8-hydroxyquinoline metal complexes against phytopathogenic fungi

Phytopathogenic fungal infections have become a major threat to agricultural production, food security, and human health globally, and novel antifungal agents with simple chemical scaffolds and high efficiency are needed. In this study, we designed and synthesized 38 8-hydroxyquinoline metal complexes and evaluated their antifungal activities. The results showed that most of the tested compounds possessed remarkable in vitro antifungal activity. Especially, compound 1e exhibited the highest antifungal potency among all target compounds, with EC50 values of 0.0940, 0.125, 2.95, and 5.96 μg/mL, respectively, against Sclerotinia sclerotiorum, Botrytis cinerea, Fusarium graminearum, and Magnaporthe oryzae. Preliminary mechanistic studies had shown that compound 1e might cause mycelial abnormalities of S. sclerotiorum, cell membrane permeability changes, leakage of cell contents, and inhibition of sclerotia formation and germination. Moreover, the results of in vivo antifungal activity of compound 1e against S. sclerotiorum showed that 1e possessed higher curative effects than that of the positive control azoxystrobin. Therefore, compound 1e is expected to be a novel leading structure for the development of new antifungal agents.
