Pteridine is an aromatic chemical compound composed of fused pyrimidine and pyrazine rings. A pteridine is also a group of heterocyclic compounds containing a wide variety of substitutions on this structure. Pterins and flavins are classes of substituted pteridines that have important biological activity. Pteridine, is a precursor in the synthesis of dihydrofolic acid in many microorganisms. Pteridine and 4-Aminobenzoic acid convert by the enzyme dihydropteroate synthetase into dihydrofolic acid in the presence of glutamate. The enzyme dihydropteroate synthetase is inhibited by Sulfonamide antibiotics
