Aminopterin N-hydroxysuccinimide ester is an antineoplastic agent with immunosuppressive properties. 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.
