Pathway Description
Acetyl sulfisoxazole Action Pathway
Escherichia coli (strain K12)
Drug Action Pathway
Acetyl sulfisoxazole is an antibacterial from the sulfanilamide drug class. It is a broad-spectrum antibiotic indicated against urinary tract infections, meningococcal meningitis, acute otitis media, inclusion conjunctivitis, toxoplasmosis, and many others. Acetyl sulfisoxazole is a synthetic bacteriostatic, meaning that it stops the bacteria from growing. This drug binds competitively to the dihydropteroate synthase enzyme. This enzyme is essential to produce dihydrofolic acid in bacteria, when it is inhibited, the bacteria cannot grow anymore because they cannot produce DNA with the folic acid. Thus drug is administered as an oral tablet. N1-acetyl sulfisoxazole is metabolized to sulfisoxazole by digestive enzymes in the gastrointestinal tract and is absorbed as sulfisoxazole (the active compound).
