Medchemexpress LLC Acetylcysteine-d3 | 131685-11-5 | 97.0% | 5 MG
Acetylcysteine-d3 is the deuterium-labeled version of Acetylcysteine. It functions as a mucolytic agent by reducing mucus thickness and is a ROS inhibitor. It also acts as a cysteine precursor, preventing hemin-induced ferroptosis through neutralizing toxic lipids. Acetylcysteine induces cell apoptosis and exhibits anti-influenza virus properties. It is considered the most stable form of cysteine for drug delivery and can be utilized in disulfidptosis studies.
