    Product Description

    Lometrexol is a folate analog antimetabolite with antineoplastic activity.1,2 At nanomolar conentrations, it inhibits GART preventing de novo purine synthesis, inhibiting DNA synthesis, arresting cells in the S phase of the cell cycle, and inhibiting tumor cell proliferation.3

    WARNING This product is not for human or veterinary use.
