Insulin-Enhancing Vanadium Pharmaceuticals: The Role of Electron Paramagnetic Resonance Methods in the Evaluation of Antidiabetic Potential

  • Barry D. Liboiron
Chapter
Part of the Biological Magnetic Resonance book series (BIMR, volume 28)

Electron paramagnetic resonance spectroscopy has been heavily used for the study of vanadium(IV) compounds in both naturally containing vanadium species and spin-labeled or metal-substituted systems. Vanadium compounds have been shown to possess potent antidiabetic properties such as normalization of blood glucose levels and lipid metabolism. Vanadium compounds, and in particular vanadyl (VIVO2+) coordination complexes, represent a potential new treatment option for diabetes mellitus. Understanding of the metabolism and mechanism of these complexes in vivo has been greatly expanded over the past 25 years in large part due to contributions made through the use of EPR spectroscopy. This review will outline the application of EPR to the study of antidiabetic vanadium(IV) compounds and highlight important studies of the in-vitro and in-vivo properties of these complexes in which EPR made a critical contribution. The role of EPR spectroscopy in the field of vanadium antidiabetic pharmaceuticals has led to major advances in the optimization of chemical structure, formulation, and descriptions of vanadium metabolism.
