General Description
• Sulfamethoxazole is an antibiotic composed of an isoxazole with a 4-aminobenzenesulfonamido and methyl-group substitution at positions 5 and 3, respectively
• Sulfamethoxazole carries out most of its action through the inhibition of dihydropteroate synthase, the enzyme responsible for the synthesis of the precursor of folic acid; inhibition of folic acid synthesis prevents DNA replication and cell division in susceptible bacteria
Application
• Sulfamethoxazole can elicit an allergic response and may be useful for immune cell studies in laboratory settings
• Sulfamethoxazole is suitable for laboratory research on infection, environmental pollution, and the physiology of susceptible bacteria
