Insulin resistance syndrome, also referred to as the metabolic syndrome or syndrome X, refers to a constellation of common metabolic and cardiovascular disorders (e.g. obesity, type 2 diabetes mellitus, hypertension, and dyslipidemia), which are all cardiovascular risk factors. Insulin resistance can be induced by fructose-rich diet in rats. We investigated the effect of vanadyl sulfate (0.2 mg...

introduction: vanadium salts have been suggested as a possible therapeutic agent for the treatment of diabetes. the aim of the present study was to clarify immunohistochemical changes that occur in the pancreatic beta ([pancreatic islet beta]) cells of vanadyl sulphate (vs) treated stz induced diabetic rats. materials and methods: male wistar rats were made diabetic with injecting a single intr...

We compared the effects of oral vanadyl sulfate (100 mg/day) in moderately obese NIDDM and nondiabetic subjects. Three-hour euglycemic-hyperinsulinemic (insulin infusion 30 mU / m / min) clamps were performed after 2 weeks of placebo and 3 weeks of vanadyl sulfate treatment in six nondiabetic control subjects (age 37 +/- 3 years; BMI 29.5 +/- 2.4 kg/m2 ) and seven NIDDM subjects (age 53 +/- 2 y...

We present a new coordination polymer, {[VO(pzdc)(H2O)2] H2O}n, built from vanadyl and pyrazine-2,5-dicarboxylate (pzdc) ions. It consists of a one-dimensional chain of vanadyl ions linked by pzdc ions. The carboxylate groups show monodentate coordination, while the pyrazine ring is present both in non-coordinated and coordinated modes. This novel structure is stabilized by an intricate network...

X-ray diffraction, Raman spectroscopy, 3’P MAS-NMR and spin-echo NMR indicated that model vanadium phosphorus oxide (VPO) precursors and catalysts contained various minor phases depending oxboth the synthetic approach and P/V ratios used. Raman spectroscopy revealed the presence of a number of micro-crystalline and amorphous V(W) and V(V) phases not evident by XRD. The presence of VOPO, phases ...

Vanadium complexes have been previously utilised as potent inhibitors of cysteine based phosphatases (CBPs). Herein, we present the synthesis and characterisation of two new fluorescently labelled vanadyl complexes (14 and 15) with bridged di-picolinic acid ligands. These compounds differ significantly from previous vanadyl complexes with phosphatase inhibition properties in that the metal-chel...

Vanadyl bearing calix[4]arene ligands have undergone evaluation against several cell lines, and show varying degrees of toxicity. For vanadyl complexed to a sulfonylcalix[4]arene, monitoring of the strong blue fluorescence revealed slow uptake kinetics. The complex is exclusively found in the cytoplasm of the cells and uptake is not due to active endocytotic mechanisms.
