Application

CEP-701 hydrate has been used as a tyrosine kinase inhibitor:
  • to study its effects on early growth response protein (EGR) genes and nerve growth factor (NGF) stimulation in human epithelial cells
  • as a supplement in reservoir solution for co-crystallization studies with human receptor-interacting protein kinase 4 (RIPK4)
  • as an FMS-like tyrosine kinase 3 (FLT3) inhibitor-gold nanoparticle conjugate to study its effects on acute myeloid leukemia

Biochem/physiol Actions

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.
CEP-701 is a Flt-3 receptor tyrosine kinase inhibitor.
