Inflammatory processes in the arterial wall are important in atherogenesis. The present review discusses the development of DiNAC as a potential new treatment modality for atherosclerosis related diseases. DiNAC, N,N'-diacetyl-L-cystine, is the disulphide dimer of N-acetyl cysteine, NAC. It was

Not all antioxidants reduce atherosclerosis. This may be because atherosclerosis has an autoimmune, inflammatory pathogenesis. As probucol is both an antioxidant and an immunomodulatory drug, it may be the immunomodulatory effect that underlies its ability to reduce atherosclerosis. N,N-Diacetyl-L-cystine is
Knut S Pettersson et al.
Basic & clinical pharmacology & toxicology, 100(1), 36-42 (2007-01-12)
N,N-diacetyl-L-cystine (DiNAC), a novel immunomodulator, stimulates contact sensitivity/delayed type hypersensitivity reactions in mice induced by oxazolone and reduces atherosclerosis in Watanabe heritable hyperlipidaemic (WHHL) rabbits. Forty-week-old WHHL rabbits were given DiNAC (3 micromol/kg per day) for 8 weeks, and endothelium-mediated
