Description

Application

Aminopterin has been used in the production of anti- neurogranin antibodies.

Biochem/physiol Actions

Aminopterin is found to inhibit growth, embryogenesis and has toxic effects in mice models. It serves as a abortifacient. Aminopterin is known to reduce the effects of acute leukemia in children.

Folic acid antagonist. Aminopterin is actively transported into cells by the folate transporter. In the cell, it is converted to a high molecular weight polyglutamate metabolite by folylpolyglutamate synthase that, in turn, binds to dihydrofolate reductase and inhibits its activity. Aminopterin-polyglutamate is degraded intracellularly by γ-glutamyl hydrolase.

Linkage

More potent, but more toxic, than methotrexate.
