Description

General description

Chemical structure: sulfonamide

Application

Sulfadiazine is a short-acting sulfonamide that is commonly used with pyrimethamine to treat toxoplasmosis in patients with acquired immunodeficiency syndrome. It is also used to treat newborns with congenital infections. Sulfadiazine has been used to control acute infections when studying murine models of reactivated toxoplasmosis.

Biochem/physiol Actions

Sulfadiazine is a sulfonamide antibiotic that blocks the synthesis of dihydrofolic acid by inhibiting the enzyme dihydropteroate synthase. Sulfadiazine is a competitive inhibitor of bacterial para-aminobenzoic acid (PABA), which is required for bacterial synthesis of folic acid. It is active against Gram positive bacteria, Gram negative bacteria and Chlamydia. Mode of resistance is via the alteration of dihydropteroate synthase or alternative pathway for folic acid synthesis.
