Application
Pyrimethamine, an inhibitor of dihydrofolate reductase
Pyrimethamine is known as an antagonist of folic acid and has an anti-malarial effect. It inhibits dihydrofolate reductase of bacteria and protozoa and affects cell division by inhibiting the conversion of dihydrofolic acid to tetrahydrofolic acid. Its inhibitory effect against human’s dihydrofolate reductase is only 1/1000 in comparison to that of bacteria or protozoa, so that it is considered to be less effective for human.
