Disulfiram (tetra ethyl thiuram disulfide, or DSF), is a disulfide derivative of N, N-diethyl dithiocarbamate (DEDTC). DSF is an FDA approved drug for the treatment of alcoholism, and at low doses continues to be a useful treatment option for those suffering from the disease. DSF is a member of the dithiocarbamate family, and is thus a metal chelator. Many cancer cells have elevated levels of copper, a metal to which DSF can bind. Thus, DSF is of great interest in cancer research as an antitumor agent, as studies suggest the DSF-copper complex may be cytotoxic to cancer cells. This could allow for targeting of some types of cancer cells with elevated copper levels by DSF.
