Inhibitor of thioredoxin reductase (TrxR) (IC50 = 20 nM; Ki = 4 nM for the NADPH-reduced form of human cytosolic TrxR). Thought to induce the mitochondrial permeability transition via inhibition of mitochondrial TrxR. Also exhibits anti-inflammatory and immunosuppressive activities; inhibits 5-lipoxygenase at high concentrations and stimulates LTA hydrolase at low concentrations.

Programmed Cell Death Poster
There are two currently recognized forms of programmed cell death: apoptosis and necroptosis. This poster summarizes the signaling pathways involved in apoptosis, necroptosis and cell survival following death receptor activation, and highlights the influence of the molecular switch, cFLIP, on cell fate.
