Aminopterin (4-aminopteroic acid) a 4-amino analog of folic acid is an antineoplastic drug with immunosuppressive properties used in chemotherapy. Aminopterin is a synthetic derivative of pterin. Aminopterin works as an enzyme inhibitor by competing for the folate binding site of the enzyme dihydrofolate reductase. Its binding affinity for dihydrofolate reductase effectively blocks tetrahydrofolate synthesis.
