ON044580
Based on 1 Customer Validation
ON044580 is a non–ATP-competitive JAK2 and BCR-ABL kinases inhibitor. ON044580 inhibits wild-type (WT) and V617F mutant JAK2 with IC50 values of 1.23 μM, 1.09 μM, respectively. ON044580 also inhibits both WT and T315I mutant BCR-ABL kinases., ON044580 blocks the IL-3–mediated phosphorylation of JAK2 and STAT5, induces apoptosis in Imatinib (HY-15463)-resistant chronic myeloid leukemia (CML). ON044580 can be used for the study of CML, myelodysplasia (MDS) and other myeloproliferative neoplasms.
