trimethoprim [Antibiotic]

Download Sequences


Accession ARO:3000188
DefinitionTrimethoprim is a synthetic 5-(3,4,5- trimethoxybenzyl) pyrimidine inhibitor of dihydrofolate reductase, inhibiting synthesis of tetrahydrofolic acid. Tetrahydrofolic acid is an essential precursor in the de novo synthesis of the DNA nucleotide thymidine. Trimethoprim is a bacteriostatic antibiotic mainly used in the prophylaxis and treatment of urinary tract infections in combination with sulfamethoxazole, a sulfonamide antibiotic.
