Aminopterin is a folic acid amino derivative with antineoplastic and immunosuppressive properties. It binds competitively to the folate binding site of the enzyme dihydrofolate reductase, blocking tetrahydrofolate synthesis, and resulting in depletion of nucleotide precursors and inhibition of DNA, RNA and protein synthesis.
