Ethaselen is a selective thioredoxin reductase (TrxR) inhibitor known for its potent inhibitory action, with IC50 values of 0.5 μM for wild-type human TrxR1 and 0.35 μM for rat TrxR1. This organoselenium compound specifically targets the unique selenocysteine-cysteine redox pair in the C-terminal active site of mammalian TrxR1. Ethaselen demonstrates significant antitumor activity, particularly against non-small cell lung cancer (NSCLC), making it a promising candidate for cancer research applications focused on apoptosis and redox regulation.
