Introduction of 144-83-2 :

Sulfapyridine, a major metabolite of Sulfasalazine, is a sulfonamide antibiotic agent. Sulfapyridine inhibits recombinant P. carinii dihydropteroate synthetase (DHPS) with an IC50 of 0.18 μM. Sulfapyridine has antibacterial, anti-inflammatory and anti-rheumatic activities[1][2][3]. In Vitro: Sulfapyridine inhibits production of IL-8, chemokine (C-X-C motif) ligand 1 (CXCL1), and monocyte chemotactic protein-1 (MCP-1) in synovial cells of rheumatoid arthritis (RA)[1].
MIC range of Sulfapyridine for Y. enterocolitica is 3.1-25 μg/mL and for Salmonella 25-100 μg/mL. Campylobacter jejuni/coli are less susceptible to Sulfapyridine with MIC values ranging from 200 to 800 μg/mL. Shigella and three of five E. coli strains are resistant to 1600 μg/mL of sulfapyridine. Two strains of E. coli are inhibited by 25 μg/mL[2]. In Vivo: Sulfapyridine (1 and 10 μg/kg; i.p.) significantly inhibits systemic allergic reaction induced by compound 48/80 in rats[4].
