FLT3

Lestaurtinib (CEP-701;KT-5555) is a multi-kinase inhibitor with potent activity against the Trk family of receptor tyrosine kinases. Lestaurtinib inhibits JAK2, FLT3 and TrkA with IC50s of 0.9, 3 and less than 25 nM, respectively.

Emavusertib, also known as CA-4948 is a potent IRAK4/FLT3 inhibitor with anti-tumor activity. CA-4948 demonstrated good cellular activity in ABC DLBCL and AML cell lines. CA-4948 demonstrated moderate to high selectivity in a panel of 329 kinases as well as exhibited desirable ADME and PK profiles including good oral bioavailability in mice, rat, and dog and showed >90% tumor growth inhibition in relevant tumor models with excellent correlation with in vivo PD modulation.
