Sulfanilamide is the prototype sulfonamide antibiotic and the parent compound from which all sulfonamide drugs are derived, used topically for vaginal candidiasis and bacterial vaginitis and historically as a systemic antibacterial before more effective agents were available. It acts as a structural analog of para-aminobenzoic acid (PABA), competitively inhibiting dihydropteroate synthase and blocking bacterial folic acid biosynthesis. It is also the precursor of carbonic anhydrase inhibitors and thiazide diuretics through chemical modification.
