Research Area: Infection
Biological Activity:
Sulfadoxine(Sulphadoxine) is an ultra-long-lasting sulfonamide with an IC50 of 249 µg/ml for P. vivax. It is often used in combination with pyrimethamine to treat or prevent malaria. Both drugs are antifolates; they inhibit the production of enzymes involved in the synthesis of folic acid within the parasites. Either drug by itself is only moderately effective in treating malaria, because the parasite Plasmodium falciparum may be able to use exogenous folic acid, i.e. folic acid which is present in the parasite’s environment, while in combination, the two substances have a synergistic effect which outbalances that ability.

Sulfadoxine 

S7821 

Application
Sulfadoxine is a sulfonamide antibiotic used in combination with pyrimethamine for the treatment or prevention of malaria. It is also used to treat various infections in livestock. Sulfadoxine and pyrimethamine is indicated for the treatment of Plasmodium falciparum malaria in patients where chloroquine resistance is suspected1. It is used to study infections caused by Toxoplasma gondii2 and has been used to prevent infections after surgery during animal studies3.
Biochem/physiol Actions
Sulfadoxine is a sulfonamide antibacterial that inhibits dihydropteroate synthase (DHPS), an enzyme that transforms 4-aminobenzoic acid (PABA) in the synthesis of dihydropteroic acid. This enzyme is also a component of the folate metabolic pathway and is upstream of dihydrofolate reductase (DHFR).

CHEBI:9329 

A sulfonamide consisting of pyrimidine having methoxy substituents at the 5- and 6-positions and a 4-aminobenzenesulfonamido group at the 4-position. In combination with the antiprotozoal pyrimethamine (CHEBI:8673) it is used as an antimalarial.
