Lometrexol hydrate (Cat No.:I015344) is an antipurine antifolate compound with various mechanisms of action. It inhibits the activity of glycinamide ribonucleotide formyltransferase (GARFT), disrupting de novo purine synthesis and leading to abnormal cell proliferation, apoptosis, and cell cycle arrest. It exhibits anticancer activity by interfering with DNA synthesis without causing significant DNA strand breaks. Additionally, Lometrexol hydrate acts as a potent inhibitor of human Serine hydroxymethyltransferase 1/2 (hSHMT1/2).
