  • Patent number: 6287586
    Abstract: Pharmaceutical compositions of vanadium biguanide complexes, and methods of use, are provided for the treatment of hyperglycemia and related disorders, e.g. hypertension, obesity, and lipid disturbances. The pharmaceutically active complexes of the invention comprise a biguanide chelant, preferably a 1-substituted biguanide chelant, capable of chelating vanadium to form a six-membered unsaturated vanadium-containing ring. The vanadium of the complex is coordinated with oxygen, sulphur or nitrogen, particularly oxygen coordinated. The complexes are formulated with a physiologically acceptable carrier. In a preferred embodiment, the complexes are formulated for oral administration.

    Inventors: Chris Orvig, John H. McNeill
  • Patent number: 6268357
    Abstract: Organic complexes of vanadium are provided, having the general structure VL3, where V is vanadium(III) and L is a monoprotic bidentate ligand that forms a five-membered, unsaturated vanadium containing ring, having vanadium coordinating oxygen or sulfur ring heteroatoms, and where the vanadium containing ring is fused to a six-membered heterocyclic ring. Preferably L is a hydroxypyrone or a hydroxypyridinone. The complexes have a number of uses, including the treatment of elevated blood glucose and related disorders, treatment of proliferative disorders, etc.
