Lestaurtinib is a potent JAK2, FLT3 and TrkA inhibitor (IC50 values are 0.9, 3 and < 25 nM, respectively). Also inhibits Aurora kinase A and B (IC50 values are 8.1 and 2.3 nM, respectively) and prevents STAT5 phosphorylation (IC50 = 20 - 30 nM). Exhibits antiproliferative activity in vitro (IC50 = 30 - 100 nM in HEL92.1.7 cells) and is effective against myeloproliferative disorders in vivo.
