Description
Trimethoprim is a synthetic antibiotic that inhibits dihydrofolate reductase (DHFR), which is necessary for the synthesis of purines, amino acids, and thymidylic acid. Trimethoprim shows prominent selectivity for bacterial DHFR over mammalian DHFR (IC50s = 5 and 30,000 nM, respectively). Trimethoprim, commonly used in combination with sulfamethoxazole to minimize acquired resistance, has long been used against urinary tract infections. It may also have prophylactic applications, for example in patients receiving biologic agents during inflammation.More related product prices
