AMMONIUM TETRATHIOMOLYBDATE

Chemical Properties

brown to black iridescent crystalline powder

Uses

Ring opening of aziridines leading to sulfides and disulfides.1

Uses

Ammonium 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 Actions

Acts 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.
