Biotransformation of BMOV in the presence of blood serum proteins

The interaction of the potent anti-diabetic agent bis(maltolato)-oxidovanadium(IV) (BMOV) with some proteins of blood serum was studied by EPR spectroscopy, pH-potentiometry and DFT calculations. The formation of cis-VO(ma)(2)(hTf), cis-VO(ma)(2)(HSA) and cis-VO(ma)(2)(IgG), their role in the biotransformation in vivo and the mechanism of transport of BMOV in blood are discussed.
