Abstract
Vanadium (V) compounds are reported to have insulin mimicking action, which render them to show excellent osteogenic activity. In the current study we investigated the effect of various vanadium compounds on osteoblast differentiation of mouse mesenchymal stem cells, C3H10t1/2 cells, and analyzed the underlying mechanism of vanadium for this action. Our data showed that treatment of C3H10t1/2 cells with V (IV) oxide complex (at 7-25 μM concentrations) induced osteoblast differentiation maximally as compared to V2O5. On the other hand, ammonium vanadate was found to dampen the osteoblast differentiation process. Based on this data, V (IV) oxide was investigated further to analyze its probable mode of action as an osteoblastic agent. The key factors implicated in osteoblast differentiation i.e., NFκB, ERK ½, AP1 and CRE were examined in response to V (IV) oxide exposure. Exposure to V (IV) oxide caused 2- and 5-folds induction of luciferase activities in cells transfected with SRE-luc and NFκB-luc reporter vectors respectively (p < 0.05). Further, exposure to V (IV) oxide enhanced the phosphorylation of ERK ½, IκB and NFκBp65 proteins. In addition, RT-PCR analysis, alizarin red staining and immunoblot analysis showed that inhibition of osteoblast differentiation in presence of PD98059 and parthenolide (inhibitors of ERK and NFκB pathways respectively) was rescued in presence of V (IV) oxide. These results suggest that V (IV) oxide up regulates osteoblast differentiation through ERK and NFκB pathways and hence could be utilized as an agent for bone formation after further analysis and validation.

Abstract
The development of new vanadium derivatives with organic ligands, which improve the beneficial actions (insulin-mimetic, antitumoral) and decrease the toxic effects, is of great interest. A good candidate for the generation of a new vanadium compound is the flavonoid quercetin because of its own anticarcinogenic effect. The complex [VO(Quer)(2)EtOH]( n ) (QuerVO) has been synthesized and characterized by means of different spectroscopic techniques (UV-vis, Fourier transform IR, electron paramagnetic resonance) and its magnetic and stability properties. The inhibitory effect on bovine alkaline phosphatase (ALP) activity has been tested for the free ligand, the complex as well as for the vanadyl(IV) (comparative purposes). The biological activity of the complex on the proliferation of two osteoblast-like cells in culture, a normal one (MC3T3E1) and a tumoral one (UMR106), has been compared with that of the vanadyl(IV) cation and quercetin. The differentiation osteoblast markers ALP specific activity and collagen synthesis have been also tested. In addition, the effect of QuerVO on the activation of the extracellular regulated kinase (ERK) pathway is reported. The bone antitumoral effect of quercetin alone was established with the cell proliferation assays (it inhibits the proliferation of the tumoral cells and does not exert any effect on the normal osteoblasts). Moreover, the complex exerts osteogenic effects since it stimulates the type I collagen production and is a weak inhibitory agent upon ALP activity. Finally, QuerVO stimulated the ERK phosphorylation in a dose-response manner and this activation seems to be involved as one of the possible mechanisms for the biological effects of the complex.

Abstract
Oxovanadium(IV) complexes of the polyalcohols sorbitol, galactitol, and mannitol, of stoichiometry Na(2)[VO(L)(2)].H(2)O, were obtained from aqueous alkaline solutions. They were characterized by elemental analysis, infrared and UV-vis spectroscopies, thermoanalytical (thermogravimetric and differential thermal analysis) data, and magnetic susceptibility measurements. The biological activities of the complexes on the proliferation, differentiation, and glucose consumption were tested on osteoblast-like cells (MC3T3E1 osteoblastic mouse calvaria-derived cells and UMR106 rat osteosarcoma-derived cells) in culture. The three complexes exerted a biphasic effect on cell proliferation, being slight stimulating agents at low concentrations and inhibitory in the range of 25-100 microM. All the complexes inhibited cell differentiation in tumor osteoblasts. Their effects on glucose consumption were also discussed. The free ligands did not show any effect on the studied biological parameters.

Abstract
Oxovanadium (IV) complexes of the cyclic polyols conduritol C (cond) and myo-inositol (inos) of stoichiometry Na(2)[VO(cond)(2)].2H(2)O and Na(2)[VO(inos)(2)].H(2)O were obtained in aqueous alkaline solutions. They were characterized by infrared and UV-Vis spectroscopies, thermoanalytical (thermogravimetric and differential thermal analysis) data and magnetic susceptibility measurements. The biological activities of the complexes on the proliferation, differentiation and glucose consumption were tested on osteoblast-like cells in culture. Conduritol C and myo-inositol did not produce any effect on these parameters. Normal and tumoral cell proliferation was inhibited about (ca.40-60%) by the two oxovanadium (IV) complexes in concentrations as low as 100microM. The complexes were also inhibitory on cell differentiation (ca. 70-80%) while they stimulate glucose consumption. Comparisons of these effects with those of the oxovanadium (IV) cation, under the same experimental conditions, were also performed.

Abstract
The vanadium(IV,V) complexes formed with two aldaric acids (D-saccharic or D-glucaric acid, and mucic or galactaric acid) in aqueous solution were characterised by employing pH-potentiometry, EPR, multinuclear NMR and UV-VIS spectroscopy. The stoichiometry and stability constants of the complexes formed were determined at 25 degrees C and ionic strength I= 0.2 mol dm(-3)(KCl). The spectral measurements revealed that vanadium(IV,V) coordinates first at the terminal COO(-) functions, forming mononuclear complexes. At pH > 3, through the metal ion-induced deprotonation and coordination of the neighbouring alcoholic functions, (COO(-), O(-)) coordinated dinuclear complexes are formed, which predominate in the pH range 4-8. In the basic pH range, the ligand molecules are displaced and binary metal hydroxo and oxo complexes are present. EPR measurements at room temperature and at 140 K proved that formation of the VO(iv) dimers is more enhanced at room temperature, but at 140 K their dissociation is favoured. An interesting pH-dependent cis-trans isomeric equilibrium was assumed and analysed by EPR and molecular modelling in the case of the complexes [(VO)(2)L(2)H(x)](x=-2 and -4). Joint evaluation of the pH-potentiometric and (51)V NMR measurements revealed that both aldaric acids are able to bind an excess of vanadium(V), through the formation of oligomeric 2:1 and 3:2 species, besides the 2:2 species formed with VO(IV).
