The interaction of vanadyl ion with gliadin has also been studied by spectrophotometric and pH-metric methods. The nature of spectra of small ligands and liquid-polymer solution provides sufficient information about ligand-polymer interaction. Here, addition of only 0.57 × 10-4 M protein solution caused on increase in absence at a particular wavelengths. The solulder as well as the maximum abso...
Jeju ground water, containing vanadium compounds, was shown to increase glutathione (GSH) levels as determined by a colorimetric assay and confocal microscopy. To investigate whether the effects of Jeju ground water on GSH were specifically mediated by vanadium compounds, human Chang liver cells were incubated for 10 passages in media containing deionized distilled water (DDW), Jeju ground wate...
The metabolic syndrome is a group of factors associated with an increased risk of atherosclerosis and diabetes. Diabetes mellitus (DM) is classified into 2 major types—type 1 DM and type 2 DM—characterized by chronic hyperglycemia resulting from defects in insulin secretion and insulin action, respectively. Several synthetic pharmaceuticals have been developed and clinically used for treating D...
Three new mononuclear oxovanadium(IV) complexes [VO(acac)(R-BIAN)]Cl (BIAN = 1,2-bis{(R-phenyl)imino}acenaphthene, R = H, 1; CH3, 2; Cl, 3) were prepared and characterized. They promoted the catalytic oxidation of olefins such as cyclohexene, cis-cyclooctene, and styrene with both tbhp (tert-butylhydroperoxide) and H2O2, and of enantiopure olefins (S(-)- and R(+)-pinene, and S(-)- and R(+)-limo...
Although the number of papers about "vanadium" has doubled in the last decade, the studies about "vanadium and actin" are scarce. In the present review, the effects of vanadyl, vanadate and decavanadate on actin structure and function are compared. Decavanadate (51)V NMR signals, at -516 ppm, broadened and decreased in intensity upon actin titration, whereas no effects were observed for vanadat...
Application of biotechnology for production and enhancing of important secondary metabolite by plant cell cultures and elicitors is one of the most noteworthy researches by scientists. This research was carried out with the aim of analysis the effects of Vanadyl Sulfate (abiotic elicitor) on media consumption by Satureja khuzistanica cells under suspension culture. Cells obtained after four sub...
The title mixed-ligand oxidovanadium(IV) compound, [VO(C(5)H(7)O(2))(2)(C(8)H(9)N(3))], contains a V(IV) atom in a distorted octahedral coordination, which is typical for such complexes. The vanadyl group and the N-heterocyclic ligand are cis to each other. The coordination bond is located at the endocyclic N atom of the benzimidazole ligand. Intra-molecular hydrogen bonds between the exo-NH(2)...
In the 21st century, patients suffering from diabetes mellitus (DM), a lifestyle-related disease, will increase more than in the 20th century. DM is threatening because of the development of many severe secondary complications, including atherosclerosis, microangiopathy, renal dysfunction and failure, cardiac abnormalities, diabetic retinopathy, and ocular disorders. Generally, DM is classified...
A vanadyl(iv) complex, K2V(O)(dtoym)2, forms polymeric interactions via intermolecular dative bonds; the intermolecular dative interaction is tuned by changes of the ligand planarity and counter cations of the vanadyl complex.
