Lometrexol (LY 264618), an antipurine Antifolate, can inhibit the activity of glycinamide ribonucleotide formyltransferase (GARFT) but do not induce detectable levels of DNA strand breaks. Lometrexol can further inhibit de novo purine synthesis, causing abnormal cell proliferation and Apoptosis, even cell cycle arrest. Lometrexol has anticancer activity. Lometrexol also is a potent human Serine hydroxymethyltransferase1/2 (hSHMT1/2) inhibitor.

Product Introduction

Bioactivity

Description	Lometrexol (LY 264618), an antipurine Antifolate, can inhibit the activity of glycinamide ribonucleotide formyltransferase (GARFT) but do not induce detectable levels of DNA strand breaks. Lometrexol can further inhibit de novo purine synthesis, causing abnormal cell proliferation and Apoptosis, even cell cycle arrest. Lometrexol has anticancer activity. Lometrexol also is a potent human Serine hydroxymethyltransferase1/2 (hSHMT1/2) inhibitor.
In vitro	Lometrexol binds tightly to GART, resulting in a rapid and prolonged depletion of intracellular purine ribonucleotides. Lometrexol (1-30 μM; 2-10 hours) induces rapid and complete growth inhibition in L1210 cells. Lometrexol (1 μM; 2-24 hours) induces cell cycle arrest in murine leukemia L1210 cells[3].
In vivo	Lometrexol (DDATHF; i.p.; 15-60 mg/kg; on gestation day 7.5) induces neural tube defects (NTDs) by disrupting purine metabolism, increasing embryonic resorption rates, and causing growth retardation in a dose-dependent manner. At 40 mg/kg, it decreases glycinamide ribonucleotide formyl transferase (GARFT) activity and alters ATP, GTP, dATP, and dGTP levels. Additionally, Lometrexol (i.p.; 40 mg/kg; on gestation day 7.5) leads to abnormal cell proliferation and apoptosis in NTDs[1].

For example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments

A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent

DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。

Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSO TargetMol | reagent

(mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.

Preparation method for in vivo formula: Take 50 μL DMSO TargetMol | reagent

main solution, add 300 μLPEG300 TargetMol | reagent

mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2O TargetMol | reagent
