Descrizione

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[1]. Sulfadiazine has been used to control acute infections when studying murine models of reactivated toxoplasmosis[2].

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[1]. 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.
