Dihydropteroate is an important intermediate in folate biosynthesis. It is a pterin created from para-aminobenzoic acid (PABA) by the enzyme dihydropteroate synthase.[2]

Tetrahydrofolate synthesis pathway

Bacteriostatic agents such as sulfonamides target dihydropteroate synthetase. The effect of dihydropteroate synthetase inhibition is comparable to that of dihydrofolate reductase inhibition by trimethoprim, another bacteriostatic agent. Combinations of these two drug types, such as the combination trimethoprim/sulfamethoxazole (TMP-SMX]), are commonly used to treat recurrent urinary tract, Shigella, Salmonella, and Pneumocystis jivoreci infections.
