ABSTRACT
Thiol homeostasis has a critical role in the maintenance of proper cellular functions and survival, being coordinated by the action of several reductive enzymes, including glutathione (GSH)/glutathione reductase (GR) and thioredoxin (Trx)/thioredoxin reductase (TrxR) systems. Here, we investigated the effects of the GR inhibitor 2-acetylamino-3-[4-(2-acetylamino-2-carboxyethylsulfanylthiocarbonylamino)phenylthiocarbamoylsulfanyl]propionic acid (2-AAPA) on the activity of thiol reductases (GR and TrxR), redox balance and mitochondrial function of A172 glioblastoma cells. 2-AAPA inhibited cell GR (IC
