Description and Uses
Sulfadoxin is a sulfonamide antibiotic that inhibits dihydropteroate synthetase (DHPS), an enzyme involved in folic acid synthesis. Sulfadoxin competes with 4-aminobenzoate (PABA), the native substrate of DHPS, and inhibits PABA incorporation into folic acid. Folate is essential for purine and pyrimidine synthesis, therefore, sulfadoxin has antiproliferative activity in non-resistant P. falciparum. Sulfadoxin inhibits growth of P. falciparum in vitro, but potency varies between non-resistant (IC50 = 4 ng/ml) and resistant strains (IC50 = 3,970 ng/ml).
Used as an antibacterial.
