The potential of the folic acid biosynthesis pathway as a target for the development of antibiotics has been acknowledged for many years and validated by the clinical use of several drugs. Trimethoprim owes its activity to powerful inhibition of bacterial dihydrofolate reductase, which is the enzyme step after the step in folic acid synthesis blocked by sulfonamides.
