On the interaction of oxovanadium(IV) with homocysteine.
TLDR
The interaction of the VO2+ cation with homocysteine, was investigated by electron absorption spectroscopy in aqueous solution at different metal-to-ligand ratios and suggests that the interaction is different from that found in the case of cysteine and occurs through pairs of amino and carboxylate groups of the amino acid.Abstract:
The interaction of the VO2+ cation with homocysteine, was investigated by electron absorption spectroscopy in aqueous solution at different metal-to-ligand ratios. The direct reduction of vanadate(V) solutions with homocysteine was also investigated. The results suggest that the interaction is different from that found in the case of cysteine and occurs through pairs of amino and carboxylate groups of the amino acid. The interaction of VO2+ with homocystine, the oxidation product of homocysteine, was also analyzed. The interest of the results in relation to vanadium metabolism and detoxification is briefly discussed.read more

TL;DR: Antioxidant properties and the free radical scavenging capacity of the new hybrid materials (containing VOSO4, NaVO3, and V-DPOT) were demonstrated through a) 2-diphenyl-1-picrylhydrazyl (DPPH) free radical, and b) intracellular-extracellular reactive oxygen species (ROS) assays, collectively showing that the hybrid silica NPs could serve as an efficient platform for nanodrug
