描述信息

In the mammalian host, dihydrofolate biosynthesis occurs via the reduction of folic acid, whereas in plasmodia (e.g. Plasmodium berghei, a malaria parasite) the biosynthesis of 7,8-dihydropteroate, an intermediate product in dihydrofolate synthesis, occurs via the enzymic catalysis of the reaction of 2-amino-4-hydroxy-6-hydroxymethyl-7,8-dihydropteridine pyrophosphate with p-aminobenzoate. Malaria parasites synthesize their folate cofactors de novo and the antimalarial action of sulfonamides is due to their inhibiting the plasmodial dihydropteroate synthesis. The enzymes 6-hydroxymethylpterin pyrophosphokinase (EC 2.7.6.3, HPPK) and dihydropteroate synthase (EC 2.5.1.15, DHPS) catalyze sequential steps in folate biosynthesis. They are present in microorganisms but absent in mammals and therefore are especially suitable targets for antimicrobials. Sulfa drugs (sulfonamides and sulfones) currently are used as antimicrobials targeting DHPS, although resistance to these drugs is increasing. An NADPH-coupled microplate photometric assay could be used for rapid screening of chemical libraries for novel inhibitors of folate biosynthesis as the first step in developing new antimicrobial drugs targeting the folate biosynthetic pathway; in the microplate, the product of the DHPS reaction, 7,8-dihydropteroic acid, is reduced to tetrahydropteroate by excess dihydrofolate reductase (DHFR) using the cofactor NADPH (PMID: 17134675, 4354403, 3546688).
7,8-dihydropteroic acid, also known as dihydropteroinsaeure or h2pte, belongs to pterins and derivatives class of compounds. Those are polycyclic aromatic compounds containing a pterin moiety, which consist of a pteridine ring bearing a ketone and an amine group to form 2-aminopteridin-4(3H)-one. 7,8-dihydropteroic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). 7,8-dihydropteroic acid can be synthesized from pteroic acid. 7,8-dihydropteroic acid can also be synthesized into 2-hydroxy-7,8-dihydropteroic acid. 7,8-dihydropteroic acid can be found in a number of food items such as rice, towel gourd, cauliflower, and silver linden, which makes 7,8-dihydropteroic acid a potential biomarker for the consumption of these food products. 7,8-dihydropteroic acid exists in all living species, ranging from bacteria to humans. In humans, 7,8-dihydropteroic acid is involved in the pterine biosynthesis.
