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.

Many cytosolic proteins lacking a signal peptide, called leaderless cargoes, are secreted through unconventional secretion. Vesicle trafficking is a major pathway involved. It is unclear how leaderless cargoes enter into the vesicle. Here, we find a translocation pathway regulating vesicle

Journal of medicinal chemistry, 48(16), 5329-5336 (2005-08-05)
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

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. We report on a

Systemic treatment for cutaneous T-cell lymphoma (CTCL) involves the use of less aggressive, well-tolerated therapies. Pralatrexate is a novel antifolate with high affinity for reduced folate carrier-1. A dose de-escalation strategy identified recommended pralatrexate dosing for patients with CTCL that
