HSB401
HSB401 is an orally active FLT3 inhibitor (IC50: 28, 5, 72, 51 nM for FLT3-WT, FLT3-D835Y, FLT3-ITD-F691L, FLT3-ITD, respectively). HSB401 downregulates FLT3 signaling and induces cell cycle arrest and apoptosis. HSB401 spares c-KIT inhibition, thereby reducing the risk of myelosuppression. HSB401 significantly suppresses tumor growth in the MV4-11 xenograft mouse model. HSB401 can be used for the research of acute myeloid leukemia.

Biological Activity
HSB401 exhibits the GI50 value of 0.772 μM in K562 cells and 0.027 μM in MV4-11 cells[1].
HSB401 (20-500 nM, 2 h) inhibits FLT3 and its downstream signaling pathways in MV4-11 cells[1].
HSB401 (20-500 nM, 24 h) induces apoptotic cell death in MV4-11 cells, the activation of caspases 7 and 9 and the cleavage of protein PARP-1[1].
HSB401 shows nanomolar affinity to bind the kinase domain of recombinant human FLT3, with a KD comparable to that of Gilteritinib (HY-12432)[1].
HSB401 (0.001-10 μM, 72 h) exhibits antiproliferative activity against MOLM13 cells and their resistant clones comparable to that of Gilteritinib, with a selectivity ratio of 1 between resistant and parental MOLM13 cells[1].
HSB401 (20-500 nM, 2 h) reduces the FLT3 autophosphorylation at Y589/591 and attenuates FLT3 downstream signaling pathways in concentration-dependent manner in MOLM13 and Ba/F3 (FLT3-ITD) cell lines[1].
HSB401 (6.25-100 nM, 24 h) exerts FLT3-specific inhibitory effects, inducing a dose-dependent increase in G1 cells in the FLT3-dependent leukemia cell lines (MV4-11, MOLM-13 cells)[1].
