Sulfamethoxazole

Sulfamethoxazole (Ro 4-2130) is a sulfonamide antibiotic with a widespread antibacterial activity. Sulfamethoxazole inhibits bacterial folate metabolism by competing with 4-Aminobenzoic acid (HY-B1008) (PABA) to act on dihydropteroate synthetase and dihydropteroate reductase. Sulfamethoxazole can be used for the study of urinary tract infections (UTIs), prostatitis, and bronchitis[1][2][3].
