Abstract:
Cytotoxic and antitumor activity of the biligand vanadyl derivative of L-malic acid (bis(L-malato)oxovanadium(IV) (VO(mal) ) was investigated in comparison with inorganic vanadium(IV) compound - vanadyl sulfate (VOSO ) and also with oxovanadium monocomplex with L-malic acid (VO(mal)) and vanadyl biscomplex with acetylacetonate. In this purpose the effect of vanadyl compounds on growth of normal human skin fibroblasts and tumor cells of different lines: mouse fibrosarcoma (L929), rat pheochromocytome (PC12), human liver carcinoma (HepG2), virus transformated mouse fibroblast (NIN 3T3), virus tr

Abstract:
The thermal behavior of vanadyl porphyrins was studied by electron spin resonance during heating of kerogens, isolated from the La Luna (Venezuela) and Serpiano (Switzerland) bituminous rocks, at 250?C for 1 to 20 days in the presence of air. During the thermal treatment of the kerogens, the vanadyl porphyrins resonance signals decrease monotonically and become quite small after 6 days of heating. Concomitantly, new vanadyl signals appear and, at longer heating times, dominate the spectrum. It is suggested that the secondary vanadyl species must have been formed from vanadyl porphyrins. Simila

Abstract:
The article presents a study of the influence of the nature of chemical solvents on the spectroscopic properties of vanadyl complexes. These compounds are used as biologically active analytical reagents and catalysts. Vanadyl (II) complexes were structured according to a typical procedure. To determine the spectral and luminescent properties of the synthesized organic compounds, dimethyl sulfoxide and distilled water were used. The results of the obtained experimental and computational studies show that the compounds under study change their spectral characteristics with the addition of binary

Treatment with vanadium, a representative of a class of antidiabetic compounds, alleviates diabetic hyperglycemia and hyperlipidemia. Oral administration of vanadium compounds in animal models and humans does not cause clinical symptoms of hypoglycemia, a common problem for diabetic patients with insulin treatment. Gene expression, using Affymetrix arrays, was examined in muscle from streptozotocin-induced diabetic and normal rats in the presence or absence of oral vanadyl sulfate treatment. This treatment affected normal rats differently from diabetic rats, as demonstrated by two-way ANOVA of

ABSTRACTIn recent years, a class of oxindole-copper and -zinc complex derivatives have been reported as compounds with efficient proapoptotic activity toward different tumor cells (e.g., neuroblastomas, melanomas, monocytes). Here we assessed the efficacy of synthesized oxindole-copper(II), -zinc(II), and -vanadyl (VO2+) complexes against adultSchistosoma mansoniworms. The copper(II) complexes (50% inhibitory concentrations of 30 to 45 μM) demonstrated greater antischistosomal properties than the analogous zinc and vanadyl complexes regarding lethality, reduction of motor activity, and oviposi

Abstract:
A method for controlled annealing of thin-film vanadium oxide coatings on the surface of quartz optical fibers is demonstrated. Thin-film coatings were obtained on a chemically thinned optical fiber surface using the method of chemical vapor deposition from organometallic compounds using vanadyl isopropoxide. It is shown that in an inert atmosphere, thin-film amorphous coatings consist mainly of a mixture of V2O5 and V6O13, which is confirmed by Raman spectra. Coatings annealed in a reducing environment demonstrate a second-order phase transition near room temperature (~65 ℃). Annealing was ca

The tests were performed for up to 1000 hours at 1300°F and 1650°F. At 1650°F, virtually all the coatings tested were severely corroded, emphasizing the necessity of improved coating materials such as ceramics to resist vanadic corr
