Ações bioquímicas/fisiológicas

Folic acid antagonist that binds to dihydrofolate reductase and inhibits its activity.
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.

Ligação

More potent, but more toxic, than methotrexate.
