111358-88-4

Off-White Solid

It is used for the treatment of pancreatic cancer and acute myelogenous leukaemia (AML)

Potent JAK2, FLT3 and TrkA inhibitor (IC 50 values are 0.9, 3 and < 25 nM respectively) that prevents STAT5 phosphorylation (IC 50 = 20 - 30 nM). Exhibits antiproliferative activity in vitro (IC 50 = 30 - 100 nM in HEL92.1.7 cells) and is effective against myeloproliferative disorders in vivo .

Lestaurtinib (111358-88-4) is a potent and selective FLT3 inhibitor (IC50= 2 nM).1,2?Inhibits RET and RET phosphorylation in medullary thyroid carcinoma cells.3?Suppresses JAK2/STAT5 signaling and the proliferation of primary erythroid cells from patients with myeloproliferative disorders.4?Potent Trk inhibitor.5?Cell permeable.

CEP-701 hydrate, also known as Lestaurtinib, can repress Janus kinase 2/signal transducer and activator of transcription 5 (JAK2/STAT5) signaling by the specific inhibition of JAK2.
