Used in research settings to study kinase signaling pathways, particularly as an inhibitor of MNK1 (MAP kinase-interacting kinase 1). It helps modulate the phosphorylation of eIF4E, a key factor in mRNA translation, making it a tool compound for investigating protein synthesis regulation in cancer and inflammatory diseases. Its application is primarily confined to cellular and molecular biology experiments to understand oncogenic signaling and potential therapeutic targets. Not used clinically, but supports drug discovery efforts in oncology and immunology.
