CEP-33779 is primarily used in biomedical research as a selective inhibitor of Janus kinase 2 (JAK2). It is valued for its ability to suppress JAK2-mediated signaling pathways, which play a key role in the regulation of immune responses and cell proliferation. Due to this property, it is investigated for potential applications in treating inflammatory diseases and certain types of cancer, particularly those driven by aberrant JAK-STAT signaling. Researchers also use CEP-33779 as a tool compound to study the role of JAK2 in cellular models, helping to elucidate mechanisms in hematological malignancies and autoimmune conditions. Its selectivity makes it suitable for in vitro and in vivo studies where precise pathway inhibition is required.
