Donor atom electrochemical contribution to redox potentials of square pyramidal vanadyl complexes
(2015)A simple donor atom additivity relationship has been used to calculate the donor atom electrochemical contribution (DEC) of the Oac (acetylacetonate-enolic oxygen), OPh (phenolic oxygen), SPh (mercaptophenol sulfur), Nam ...

Insulin-mimetic action of vanadium compounds on osteoblast-like cells in culture
(1997)Vanadium compounds mimic insulin actions in different cell types. The present study concerns the insulin-like effects of three vanadium(V) derivatives and one vanadium(IV) complex on osteoblast-like (UMR106 and MC3T3E1) ...

Is vanadate reduced by thiols under biological conditions? Changing the Redox potential of V(V)/V(IV) by complexation in aqueous solution
(2010)Although dogma states that vanadate is readily reduced by glutathione, cysteine, and other thiols, there are several examples documenting that vanadium(V)-sulfur complexes can form and be observed. This conundrum has ...

Model investigations for vanadium-protein interactions: Vanadium(III) compounds with dipeptides and their oxovanadium(IV) analogues
(2002)The reaction of VCl3 with 1,10-phenanthroline and a series of dipeptides (H2dip), having aliphatic as well as aromatic side chains, in methyl alcohol and in the presence of triethylamine affords vanadium(III) compounds of ...

Oxidovanadium(IV/V) complexes as new redox mediators in dye-sensitized solar cells: A combined experimental and theoretical study
(2015)Corrosiveness is one of the main drawbacks of using the iodide/triiodide redox couple in dye-sensitized solar cells (DSSCs). Alternative redox couples including transition metal complexes have been investigated where ...

Synthetic analogs for oxovanadium(IV/V)-glutathione interaction: An NMR, EPR, synthetic and structural study of oxovanadium(IV/V) compounds with sulfhydryl-containing pseudopeptides and dipeptides
(2000)The reaction of [VO(CH3COO)2(phen)] (phen = 1,10-phenanthroline) with the sulfhydryl-containing pseudopeptides (scp), N-(2-mercaptopropionyl)glycine (H3mpg), N-(2-mercaptopropionyl)cysteine (H4m2pc), N-(3-mercaptopropion ...
