Sulfacetamide (sodium salt)

Sulfacetamide is a sulfonamide antibiotic that is bacteriostatic against Gram-positive and Gram-negative bacteria. It inhibits dihydropteroate synthase (IC50 = 9.6 µM), blocking the synthesis of dihydrofolic acid, and also inhibits bacterial 4-aminobenzoic acid (Cay-18659), which is required for the synthesis of folic acid.Formal Name: N-[(4-aminophenyl)sulfonyl]-acetamide, monosodium salt.
