Abstract: Disclosed are vanadium (V) compounds and pharmaceutical compositions comprising these vanadium compounds. Also disclosed are methods of making and using these vanadium compounds, for example, to treat cancer (e.g., including brain cancer).

Abstract: The present application relates to preparation methods and uses of vanadium complexes providing a consistent and stable preparation. More specifically, the present application relates to preparation of vanadium citrate salts, phosphate salts, or combinations thereof, characterization of the properties of such salts, and methods using the same.

Abstract: This invention consists of the production of a salt of acyl phosphate in an aqueous solution by a process which involves (1) acylation of phosphoric acid (H.sub.3 PO.sub.4) with an acid anhydride of the general formula RCOX, where R can be hydrogen or a lower alkyl or aryl group having from 1 to 10 carbon atoms, and X can be a leaving group of the general formula OR, OCOR, X or NR.sub.2, followed by (2a) extraction of acyl phosphate to water by treatment of the reaction mixture with an aqueous bicarbonate or hydroxide solution or other basic aqueous solution, if the reaction is carried out in non-aqueous solvent or (2b) in the case where water has been used as reaction solvent acidification with acid or acid form of a carbon exchange resin.
