Acetylcysteine-d₃  (Synonyms: N-Acetylcysteine-d₃; N-Acetyl-L-cysteine-d₃; NAC-d₃)

Acetylcysteine-d₃ is the deuterium labeled Acetylcysteine. Acetylcysteine (N-Acetylcysteine) is a mucolytic agent which reduces the thickness of the mucus. Acetylcysteine is a ROS inhibitor. Acetylcysteine is a cysteine precursor, prevents hemin-induced ferroptosis by neutralizing toxic lipids generated by arachidonate-dependent activity of 5-lipoxygenases. Acetylcysteine induces cell apoptosis. Acetylcysteine also has anti-influenza virus activities. In addition, Acetylcysteine is the most stable form of cysteine during drug delivery and can be used in disulfidptosis studies^{[1][2][3][4][5][6][7][8]}.

Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs^[1].
