Application

Aminopterin concentrate supplement for hybridoma cell culture applications.

Biochem/physiol Actions

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.

Reconstitution

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.

We report, for the first time, the biological activities of four-carbon-atom bridged classical antifolates on dihydrofolate reductase (DHFR), thymidylate synthase (TS), and folylpolyglutamate synthetase (FPGS) as well as antitumor activity. Extension of the bridge homologation studies of classical two-carbon bridged

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
