Abstract: An antimalarial conjugate according to a non-limiting embodiment of the present invention may include a metallocene, a carbohydrate, and an antimalarial agent. The metallocene may include two cyclopentadienyl rings bound to a central metal atom. The carbohydrate and the antimalarial agent may be appended to at least one of the cyclopentadienyl rings of the metallocene, wherein the antimalarial agent has therapeutic properties directed to treating and/or preventing malaria. The metallocene may be ferrocene, the carbohydrate may be glucose, and the antimalarial agent may be chloroquine.

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.

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.
