  • Patent number: 10953099
    Abstract: The present invention provides a novel class of dithiocarbamate-metal complexes and their uses in medicine. Also provided by the invention are combinations and pharmaceutical compositions, comprising a dithiocarbamate (or thiuram disulphide) such as disulfiram and cyclodextrin, with a source of a heavy metal. Surprisingly, the inventors found a synergistic potentiation of the anti-tumor effect, when a dithiocarbamate/heavy metal mixture was combined with a cyclodextrin. The compounds and combination of the invention are particularly useful in the treatment of tumor diseases, and other disorders. Provided are the compounds, combination, pharmaceutical compositions and kits, as well as methods for the preparation of the combinations of the invention.

  • Patent number: 8435966
    Abstract: The invention is related to association products of xanthates and cyclodextrins, pharmaceutical formulations made therefrom, and medicaments containing these formulations for treating Alzheimer's, viral, tumor, cardiovascular, and autoimmune diseases such as rheumatism, multiple sclerosis, alopecia areata, lupus erythematosus, stroke, lung edema, or for use as radio-protectors. The association products contain a xanthate of general formula I whereby R1 represents a possibly substituted aryl or alkyl residue and R2 represents a metal atom, a possibly substituted alkyl, alkoxy, amino or ammonium group or halogen, and a cyclodextrin, whereby the cyclodextrin can be either a substituted or non-substituted alpha-, beta- or gamma-cyclodextrin. Furthermore, the invention is related to the use of the association products for chemical syntheses.
