Application

N-Acetyl-L-cysteine has been used to study its protective effect against styrene-induced cochlear injuries in rats. It has also been used as a supplement in basal chemically-defined medium (BDM) for the culture of oligodendrocyte precursor cells.

Biochem/physiol Actions

Antioxidant and mucolytic agent. Increases cellular pools of free radical scavengers. Reported to prevent apoptosis in neuronal cells but induce apoptosis in smooth muscle cells. Inhibits HIV replication. May serve as a substrate for microsomal glutathione transferase.
