N,N’-diacetyl-L-cystine (DiNAC) is the disulphide dimer of N-acetylcysteine with immunomodulating properties. N,N’-diacetyl-L-cystine is a potent, orally active modulator of contact sensitivity/delayed type hypersensitivity reactions in rodents. N,N’-diacetyl-L-cystine also has antiatherosclerotic effects in Watanabe-heritable hyperlipidemic rabbit (WHHL) rabbits[2].IC50 & Target: ImmunomodulatorIn Vivo: N,N’-Diacetyl-L-cystine (DiNAC; 0-973.11 μg/kg; oral administration; daily; for 12 weeks; WHHL rabbits) treatment reduces by 50% thoracic aorta atherosclerosis, without affecting plasma lipid levels.
