Sulfasalazine is a drug for the treatment of rheumatoid arthritis and ulcerative colitis. Sulfasalazine is reported to suppress NF-κB activity.
Treatment of SW620 colon cells with sulfasalazine inhibits TNFα-, LPS-, or phorbol ester-induced NFκB activation. NFκB-dependent transcription is inhibited by sulfasalazine at micro- to millimolar concentrations. TNFα-induced nuclear translocation of NFκB is prevented by sulfasalazine through inhibition of IκBα degradation[1]. Pre-incubation with 5 mM of sulfasalazine alone significantly increases basal mRNA expression of all pro-inflammatory cytokines with levels of IL-6 mRNA increased by 80-fold compared with vehicle control[2]. Once digested, sulfasalazine is cleaved into sulfapyridine and 5-aminosalicylic acid by colonic bacteria, and the latter, too, is reported to suppress NF-kappaB activity[3].
At low doses (0.25 mM), SAS is able to suppress glioma growth by over 60% compared to untreated controls[3].
