Abstract

SUMMARYWe investigated the effects of bucillamine and N-acetyl-L-cysteine (NAC) on cytokine production and CIA. Bucillamine and NAC inhibited NF-κB activation and tumour necrosis factor-alpha (TNF-α) mRNA expression in human monocytic leukaemia cell line THP-1, and cytokine production from monocyte cell lines at concentrations >10-3 M. They also inhibited cytokine production and CIA in mice at a dose of 500 mg/kg. These results suggest that NF-κB inhibitors such as bucillamine and NAC may inhibit cytokine-related diseases, including arthritis.
