Background:
Disulfiram-d20 is intended for use as an internal standard for the quantification of disulfiram by GC- or LC-MS. Disulfiram is a copper and zinc chelator and an irreversible inhibitor of aldehyde dehydrogenase (IC50 = 0.1 mM).1 It also inhibits the copper-dependent enzyme dopamine β-hydroxylase, which prevents the breakdown of dopamine.2 When in complex with copper, disulfiram has been shown to inhibit purified 20S proteasome (IC50 = 7.5 μM) and 26S proteasome (IC50 = 20 μM) from MDA-MB-0231 breast cancer cells.3,4 Disulfiram (at 250 nM) induces reactive oxygen species, activates JNK and p38 pathways, and inhibits NF-κB activity, which suppresses self-renewal in cancer stem cells.5,6
