Biological Activity

N-Acetyl-L-cysteine ethyl ester is a lipophilic, cell-permeable cysteine derivative that acts as a glutathione-related antioxidant, mucolytic agent, and hydrogen sulfide donor. Upon entering cells, it rapidly releases N-acetyl-L-cysteine and cysteine to elevate intracellular glutathione levels and promote antioxidant defense mechanisms. These actions protect cells against hydroperoxide-induced oxidative damage and enhance cellular resistance to oxidative stress in various tissues. [1][2]
