Acetylcysteine (NAC) is an N-acetyl derivative of cysteine, a ROS inhibitor and mucolytic agent. Acetylcysteine induces apoptosis, can be used to reduce mucus thickness, and has anti-influenza viral activity.

Acetylcysteine-15N is a version of Acetylcysteine (T0875) labeled with nitrogen-15 (\[^15N\]). Acetylcysteine (N-Acetylcysteine) functions as a mucolytic agent, effectively reducing mucus viscosity. As a reactive oxygen species (ROS) inhibitor, it serves as a cysteine precursor and prevents heme-induced ferroptosis by neutralizing toxic lipids produced via arachidonic acid-dependent 5-lipoxygenase activity. Additionally, Acetylcysteine (T0875) can induce apoptosis and exhibits antiviral activity against influenza. It represents the most stable form of cysteine for drug delivery and is utilized in studies of disulfidptosis.

Acetylcysteine-D3 is the deuterated form of Acetylcysteine. Acetylcysteine (T0875) (N-Acetylcysteine), a mucolytic agent, is utilized to decrease mucus viscosity. It functions as an ROS inhibitor and serves as a precursor to cysteine. By neutralizing the toxic lipids produced via arachidonic acid-dependent 5-lipoxygenase activity, it helps prevent ferroptosis induced by heme. Furthermore, Acetylcysteine (T0875) can trigger apoptosis and exhibits antiviral activity against influenza viruses. It represents the most stable form of cysteine for drug delivery, suitable for disulfidptosis research.
