NCIt definition : A sulfhydryl-containing carbamate that is the primary in vivo metabolite of disulfiram.
Diethyldithiocarbamate chelates zinc, thereby inhibiting metalloproteinases, thereby
preventing the degradation of the extracellular matrix and inhibiting an initial step
in cancer metastasis and angiogenesis. A known inhibitor of superoxide dismutase,
this agent can either potentiate or protect against cell oxidative damage caused by
ionizing radiation, depending on the time of administration. (NCI04);
