Description | Sulfasalazine is a sulfa derivative of mesalazine, used as an anti-inflammatory agent to treat bowel disease and rheumatoid arthritis. Sulfasalazine is a potent and specific inhibitor of nuclear factor kappa B (NF-κB), TGF-β and COX-2. Sulfasalazine induces ferroptosis, apoptosis and autophagy. | |||

In vitro | Sulfasalazine, like methotrexate, enhances adenosine release at an inflamed site and that adenosine diminishes inflammation via occupancy of A2 receptors on inflammatory cells. [1] Sulfasalazine treatment for 4 hours inhibits kappaB-dependent transcription with an IC50 value of approximately 0.625 mM. Sulfasalazine (2.5 mM) results in cell death of T-lymphocytes in a dose- and time-dependent manner. Sulfasalazine but not 5ASA or sulfapyridine, strongly inhibits NF-kappaB activation and potently induces apoptosis in T-lymphocytes. [2] Sulfasalazine is cleaved into sulfapyridine and 5-aminosalicylic acid (5-ASA; mesalamine) by colonic bacteria, and the latter, too, is reported to suppress NF-kappaB activity. Sulfasalazine but not its cleaved form 5-ASA causes a dose-dependent inhibition of glioma growth, this effect is entirely attributable to the inhibition of cystine uptake via the system x(c)(-) cystine-glutamate transporter. Sulfasalazine inhibits cystine uptake causing a chronic depletion of intracellular GSH and consequently compromised cellular redox defense which stymied tumor growth. [3] |

In vivo | Sulfasalazine markedly decreases the number of leukocytes that accumulated in the inflamed (carrageenan, 2 mg/ml) air pouch in the murine air pouch model of inflammation. Sulfasalazine treatment promotes a marked increase in splenocyte 5-aminoimidazole-4-carboxamidoribonucleotide (AICAR) concentration, which is consistent with the in vitro observation that sulfasalazine inhibits AICAR transformylase.
