Application

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

Biochem/physiol Actions

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.

Extensive biochemical and pharmacological evidence indicates that LY231514 is a novel antifolate antimetabolite. LY231514 is transported into cells mainly through the reduced folate carrier system and extensively metabolized to polyglutamated forms. The polyglutamates of LY231514 inhibit at least three key

Lometrexol inhibits the first folate-dependent enzyme in de novo purine biosynthesis and is avidly polyglutamated and retained in tissues expressing folylpolyglutamate synthetase. Although clinical studies have been limited by cumulative toxicity, preclinical studies show that pretreatment with folic acid can

The impact of p53 status on cellular sensitivity to antifolate drugs has been examined in seven human cell lines (A549, MCF7, T-47D, CCRF-CEM, COR-L23, A2780, and HCT-116) and p53 nonfunctional counterparts of two of the cell lines (HCT-116/N7 and A2780/CP70).

Mouse L1210 cell variants were selected for resistance to 5, 10-dideazatetrahydrofolate, a potent inhibitor of the first folate-dependent enzyme in de novo purine synthesis, glycinamide ribonucleotide formyltransferase. The drug-resistant phenotype selected was conditional to the folate compound used to support
