Description: Potent thioredoxin reductase (TrxR) inhibitor
Chemical Name: (Diphenyl-2-thienylphosphine-κP)[2-(4-methoxyphenyl)ethynyl]gold
Purity: ≥98% (HPLC)
Biological Activity
Potent thioredoxin reductase (TrxR) inhibitor (EC50 = 2.8 nM, IC50 = 0.03 and 0.1 μM in MCF-7 cells and HT-29 cells, respectively). Highly stable in vivo; exhibits no significant ligand exchange with albumin. Inhibits tumor proliferation in vitro and in vivo by inducing cell death. Selectively kills cancer cells.

Autophagy Poster
Autophagy is a cellular process used by cells for degradation and recycling. Written by Patricia Boya and Patrice Codogno, this poster summarizes the molecular machinery, physiology and pathology of autophagy. Compounds available from Tocris are listed.
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.
