“…69,70 Oxovanadium(IV) coordination is favored in basic media and only occurs with sugar molecules provided with pairs of adjacent OH-groups. 69,71 A great number of VO 2+ /monosaccharide complexes have been reported in recent years. Their stoichiometries are summarized in Table 1.…”

Nos ultimos anos, vêm se acumulando as evidências sobre a necessidade de vanádio dos organismos mais evoluídos. Estudos de compostos modelos constituem-se numa importante ferramenta para o entendimento dos diferentes aspectos da bioquímica deste bioelemento. Neste artigo, apresentamos os resultados dos nossos estudos, assim como os de outros grupos de pesquisa, sobre compostos modelos relacionados a vários aspectos do metabolismo e detoxificação do vanádio e a haloperoxidasas dependentes do vanádio. São também apresentadas informações sobre as interações do cátion oxovanádio(IV), relevante do ponto de vista biológico, com bioligantes importantes, tais como nucleotideos, carboidratos, fosfatos e outros sistemas correlatos.Increasing evidence on the need of the higher forms of life for vanadium has accumulated during recent years. Model studies have become a very important tool to attain a better understanding of different aspects of the biochemistry of this bioelement. In this account we present the results of our own studies, as well as those of other research groups, on models related to different aspects of its metabolism and detoxification and to vanadium dependent haloperoxidases. Additional information about the interaction of the biologically relevant oxovanadium(IV) cation with important bioligands, such as nucleotides, carbohydrates, phosphates and related systems are also presented.

“…They display the three-band pattern characteristic of the coordination of the VO 2+ cation with pairs of deprotonated cis-OH-groups of saccharides. 28,34,36 The diffuse reflectance spectra of the compounds are similar to the electronic spectra in aqueous solutions. Consequently, one may conclude that the coordination sphere is retained upon dissolution.…”

“…This behavior clearly confirms the IR results. On the other hand, complex 2 shows the three-band pattern characteristic of the coordination of the VO 2þ cation with pairs of deprotonated cis-OH-groups of saccharides [5,36,37], confirming that only these ligands are present in this coordination sphere. The overall spectroscopic behavior also resembles that observed in the VO 2þ /glucuronate system, which generates complexes with similar coordination characteristics [38,39].…”
