Auranofin

Auranofin is a gold-thiol complex with diverse biological activities. It inhibits thioredoxin reductase (IC50 = 0.2 µM), increases oxidation of mitochondrial peroxiredoxin 3 (PRDX3), and induces apoptosis in Jurkat T cells. Auranofin reduces the production of IL-6 and activation of JAK1 and JAK2, as well as inhibits nuclear translocation of NF-kB, in primary human synoviocytes. It is active against P. falciparum and S. mansoni in vitro when used at concentrations ranging from 1 to 10 µM. In vivo, auranofin (2 mg/kg per day) reduces the number of peripheral blood mononuclear cells (PBMCs) containing viral DNA and delays viral rebound in macaques infected with the mac251 strain of simian immunodeficiency virus (SIV). Auranofin (0.5 µM) synergizes with buthionine sulfoxime (BSO) to decrease glutathione peroxidase 4 (GPX4) levels, increase intracellular accumulation of reactive oxygen species (ROS), and induce ferroptosis in Huh7 and HepG2 hepatocellular carcinoma cells.Formal Name: [1-(thio-kappaS)-beta-D-glucopyranose 2,3,4,6-tetraacetato](triethylphosphine)-gold.
