Applicazioni

Lometrexol hydrate was used to compare the biological activity of potent inhibitor of human GARFTase.

Azioni biochim/fisiol

Glycinamide Ribonucleotide Formyltransferase (GARFTase) is a folate-dependent enzyme required for de novo purine synthesis. Lometrexate is a potent inhibitor of GARFTase, but does not interfere with enzymes involved in the synthesis of folate. Lometrexerol has been tested clinically for the treatment of various cancers as an anti-folate like agent, similar to methotrexate. Treatment with lometrexol rapidly decreases ATP and GTP levels, cell cycle arrest and induces apoptosis. Although depletion of nucleotide pools induces p53 expression, lometrexol is cytotoxic in both wild-type and mutant p53 expressing tumor cells. Lometrexol is cytotoxic in CCRF-CEm leukemia cells with an IC50 of 2.9 nM.

The class of folate antimetabolites typified by (6R)-dideazatetrahydrofolate (lometrexol, DDATHF) are specific inhibitors of de novo purine synthesis because of potent inhibition of glycinamide ribonucleotide formyltransferase (GART) but do not induce detectable levels of DNA strand breaks. As such, they

Antifolate drugs, as a class, have broad-spectrum activity against both hematologic and solid human malignancies. The pharmacokinetics of the classical antifolate methotrexate have been well-defined and pharmacokinetic data can be exploited to reduce the toxicity and enhance the activity of

We determined the mechanisms of resistance of human CCRF-CEM leukemia cells to methotrexate (MTX) vs. those to six novel antifolates: the polyglutamatable thymidylate synthase (TS) inhibitors ZD1694, multitargeted antifolate, pemetrexed, ALIMTA (MTA) and GW1843U89, the non-polyglutamatable inhibitors of TS, ZD9331

L1210/D3 mouse leukemia cells are resistant to 5, 10-dideazatetrahydrofolate due to expansion of cellular folate pools which block polyglutamation of the drug (Tse, A., and Moran, R. G. (1998) J. Biol. Chem. 273, 25944-25952). These cells were found to have
