N-acetyl-L-cysteine powder USP CP antioxidant cas 616-91-1
The N-acetyl derivative of CYSTEINE. It is used as a mucolytic agent to reduce the viscosity of mucous secretions. It has also been shown to have antiviral effects in patients with HIV due to inhibition of viral stimulation by reactive oxygen intermediates.
Application
N-Acetyl-L-cysteine has been used to suppress oxygen-dependent hydroxyurea sensitivity in Saccharomyces cerevisiae.[1] It has also been used as an antioxidant for the treatment of C2C12 murine myoblasts
