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.
