AMMONIUM TETRATHIOMOLYBDATE Usage And Synthesis
Chemical Propertiesbrown to black iridescent crystalline powder
UsesRing opening of aziridines leading to sulfides and disulfides.1
UsesAmmonium tetrathiomolybdate is used as an important reagent in synthetic chemistry and as a building block in bioinorganic chemistry. It is used in the treatment of copper toxicosis in animals and in Wilson's disease. It acts as a chelator in vivo to reduce copper levels. It interferes with angiogenesis and reduces tumor growth. Further, it is used in the synthesis of heterometallic sulfide clusters stabilized with dppm [bis(diphenylphosphino)methane] ligands. It is involved in the ring opening of aziridines leading to sulfides and disulfides.
Biochem/physiol ActionsActs as a chelator in vivo to reduce copper levels. Tetrathiomolybdate interferes with angiogenesis and reduces tumor growth. Its mechanism may involve inhibition of NF-κB and downstream cytokines.
