Abstract

The interaction of chloroquine (CQ) with peptide-bonded-ethyl selenol and ethanethiol was experimentally and thermodynamically studied, indicating that CQ can bind to peptide-bonded active selenols through electrostatic interactions with a protonated triethylamine moiety, revealing a reasonable mechanism by which CQ inhibits thioredoxin reductase (TrxR) and significantly reduces oxidoreductase activity.
