FLC-8
FLC-8 is an orally active FLT3 inhibitor with IC50 values of 10.2 nM, 11.6 nM and 24.10 nM against human FLT3-WT, FLT3-G697R and FLT3-N676D, respectively. FLC-8 inhibits FLT3 autophosphorylation and downstream STAT5, AKT and ERK signaling pathways, and induces apoptosis in acute myeloid leukemia (AML) cells. FLC-8 exhibits potent antitumor activity in the MV4-11 xenograft model. FLC-8 can be used for the research of acute myeloid leukemia.

FLC-8 (3.5 h) potently inhibits FLT3-WT kinase activity with an IC50 of 10.2 nM[1].
FLC-8 (50 μM; 24 h) covalently binds to FLT3 kinase domain at the Cys807 residue[1].
FLC-8 (72 h) potently inhibits MV4-11 and MOLM-13 cell proliferation with IC50 values of 0.28 nM and 2.45 nM, respectively[1].
FLC-8 (72 h) potently inhibits proliferation of BaF3-FLT3ITD, BaF3-FLT3ITD-G697R, and BaF3-FLT3ITD-N676D cells with IC50 values of 3.10 nM, 11.6 nM, and 24.10 nM respectively, while showing reduced activity against other FLT3 mutant BaF3 cell lines[1].
FLC-8 (1 μM) demonstrates a narrow kinome inhibition spectrum with an S10 score of 0.096, potently inhibiting FLT3-WT, FLT3-ITD, PDGFRα, NCOA4-RET, and RET L730I at 1 μM[1].
FLC-8 (0.1-100 nM; 24 h) induces dose-dependent G0-G1 phase arrest in MV4-11 and MOLM-13 AML cells after 24 h incubation[1].
FLC-8 (0.1-100 nM; 24-72 h) induces dose-dependent apoptosis in MV4-11 and MOLM-13 AML cells over 24, 48, and 72 h[1].
FLC-8 (0.1-30 nM) induces apoptosis in MV4-11 cells via activation of the intrinsic apoptotic pathway, as shown by upregulation of pro-apoptotic genes/proteins, downregulation of anti-apoptotic BCL-2, cleavage of caspase-3 and PARP, and DNA fragmentation detected by TUNEL staining[1].
FLC-8 (0.1-30 nM; 12 h) inhibits FLT3 autophosphorylation and downstream STAT5, AKT, and ERK phosphorylation in a dose-dependent manner in MV4-11 cells[1].

-
Concentration:0.1, 0.3, 1.0, 3.0, 10, 30 nM
-
Incubation Time:12 h
-
Result:Potently inhibited FLT3 autophosphorylation in a dose-dependent manner, with significant suppression at 10 nM.
Reduced phosphorylation levels of STAT5, AKT, and ERK in a concentration-dependent fashion.
Exhibited superior inhibition of FLT3-mediated signaling at 30 nM compared to Quizartinib (HY-13001).
FLC-8 (10-50 mg/kg; p.o., i.p.; daily; 14 days) exhibits modest, dose-dependent antitumor activity against BaF3-FLT3-ITD-G697R AML xenografts, with the highest efficacy (TGI = 32%) achieved at an oral dose of 50 mg/kg[1].
FLC-8 (1-10 μM; immersion; 24 hours) demonstrates a favorable hematopoietic safety profile in transgenic zebrafish, with no significant impairment of neutrophil production at concentrations up to 10 μM[1].
