Sulfapyridine

Sulfapyridine(Dagenan) is a sulfonamide antibacterial.(In Vitro):ulfapyridine 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).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.(In Vivo):Sulfapyridine (1 and 10 μg/kg; i.p.) significantly inhibits systemic allergic reaction induced by compound 48/80 in rats.
