Sulfanilamide, often called 4-aminobenzenesulfonamide, is an antibiotic in the sulfonamide class that inhibits bacterial growth by inhibiting the production of folic acid. It competes with para-aminobenzoic acid, the natural substrate for the enzyme dihydropteroate synthetase which is essential in the folic acid cycle.
