None so far has surpassed bis(maltolato)oxovanadium(IV) (BMOV) for glucose- and lipid-lowering in an orally available formulation. Ligand choice is clearly an important factor in pharmacological efficacy of vanadium compounds as insulin enhancing agents. In this study, we kept the ligand and dose the same, varying instead the metal ion bound to the maltolato ligand in a series of binary complexes of neutral charge. A requirement for vanadyl ion as the metal ion of choice was apparent; no other metal ion tested served as a suitable substitute. Amongst [MoO2](2+), Co(II), Cu(II), Cr(III), and Zn(II), only [MoO2](2+) and Co(II) showed any hypoglycemic activity at the ED50 dose for bis(maltolato)oxovanadium(IV), 0.6 mmol kg(-1) by oral gavage in streptozotocin (STZ)-diabetic rats within 72 It of administration of compound.
