Application

Aminopterin concentrate supplement for hybridoma cell culture applications.

Biochem/physiol Actions

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.

Preparation Note

Reconstitute contents of vial with 10 mL sterile cell culture medium. Stock solution is sufficient to prepare 500 mL medium. Final working concentration: 0.4 μM aminopterin.

Other Notes

More potent, but more toxic, than methotrexate.

Maternal exposures to aminopterin and methotrexate have been associated with a pattern of malformation which includes prenatal-onset growth deficiency, severe lack of ossification of the calvarium, hypoplastic supraorbital ridges, small, low-set ears, micrognathia, and limb abnormalities.

Nonpolyglutamatable antifolates are potentially of therapeutic interest for the treatment of tumors that are inherently refractory, or have become resistant, to classical antifolates as a result of decreased expression of the enzyme folylpolyglutamate synthetase. An interesting class of water-soluble nonpolyglutamatable

N-[4-[[(2,4-diamino-6-pterdinyl)methyl]amino]benzoyl]-L/D-glutamic acid (L/D-AMT) is an investigational drug in phase 1 clinical development that consists of the L-and D-enantiomers of aminopterin (AMT). L/D-AMT is obtained from a novel process for making the L-enantiomer (L-AMT), a potent oral antiinflammatory agent. The purpose
