N-Acetyl-D-cysteine is a synthetic cysteine derivative that functions as an antioxidant and reactive oxygen species (ROS) scavenger. Driven by its free thiol group, it directly neutralizes oxidant species such as hydrogen peroxide and hypochlorous acid to modulate oxidative stress signaling pathways. Unlike its enantiomer N-acetyl-L-cysteine, N-acetyl-D-cysteine is not incorporated into cellular glutathione biosynthesis, making it a valuable tool to distinguish direct antioxidant activity from glutathione-dependent cellular responses.
