Biochemical Physiological Actions | Methotrexate is an allosteric inhibititor of dihydrofolate reductase (DHFR), the enzyme that catalyzes the conversion of dihydrofolate to tetrahydrofolate. Since tetrahydrolfolate is required for purine and pyrimidine synthesis, methotrexate treatment results in the inhibition of DNA and RNA synthesis. |
