HM43239 is a novel potent small molecule FLT3 inhibitor that selectively inhibits not only FLT3 wild type, ITD mutants or TKD mutations, but also FLT3 ITD/TKD double mutations. IC50s' of HM43239 against FLT3 WT, FLT3 ITD and FLT3 D835Y kinases are 1.1 nM, 1.8 nM and 1.0 nM, respectively.

A2493 Anti-FLT3 / CD135 Anti-FLT3 / CD135 (IMC-EB10) is a fully human IgG1 monoclonal antibody, targeting the FLT3 tyrosine kinase receptor (CD135) with potential antineoplastic activity. It binds to FLT3 and blocks FLT3 ligand binding to FLT3 and subsequent FLT3 phosphorylation, which may result in the inhibition of FLT3-mediated signal transduction pathways. MW: 145.5 KD.
E1437New PHI-101 PHI-101 is an orally active, potent third-generation inhibitor of FLT3 that overcomes resistance to multiple drug-resistant mutations. It has potential for research in relapsed or refractory acute myeloid leukemia (AML).
E4598New MEN1703(SEL24,SEL24-B489) MEN1703(SEL24-B489,SEL24, Pim/flt3 kinase inhibitor SEL24) is a potent, type I, orally active, dual inhibitor of PIM and FLT3-ITD, that exhibits Kd values of 2 nM for PIM1, 2 nM for PIM2 and 3 nM for PIM3, respectively. MEN1703 exhibits its broad therapeutic potential in treatment of acute myeloid leukemia.
S5986New FLT3-IN-3 FLT3-IN-3 is a potent inhibitor of FLT3 with IC50 values of 13 nM and 8 nM for FLT3 WT and FLT3 D835Y, respectively. FLT3-IN-3 effectively suppresses the proliferation of FLT3-ITD-positive MV4-11 and MOLM-13 cell lines at low nanomolar concentrations.
