BSc5371 is a potent and irreversible FLT3 inhibitor (Kds: 1.3, 0.83, 1.5, 5.8, and 2.3 nM for mutant FLT3 D835H, FLT3 ITD D835V, FLT3 ITD F691L, FLT3-ITD, and wild type FLT3 wt).
FLT3 ITD-IN-1 (Compound 1) is a highly potent inhibitor of FLT3 internal tandem duplications (FLT3-ITD). It exhibits remarkable inhibitory effects against FLT3 and FLT3-ITD, with impressive IC50 values of 38.2 nM and 144.1 nM, respectively. Moreover, FLT3 ITD-IN-1 shows exceptional antiproliferative activities against several acute myeloid leukemia cell lines [1].
PROTAC FLT-3 degrader 1 is a PROTAC FLT-3 degrader of internal tandem duplication (ITD) with an IC50 of 0.6 nM and exhibits anti-proliferative activity.
JH-IX-179 is a novel type I ATP competitive and highly selective FLT3 inhibitor. JH-IX-179 is much more selective for FLT3 and FLT3 mutants than for Kronani. In addition, JH-IX-179 showed little human serum protein binding and effectively inhibited autoph
AC-4-130, a powerful inhibitor of the SH2 domain of STAT5, effectively hinders STAT5 activation, dimerization, nuclear translocation, and transcription of genes reliant on STAT5. This compound directly binds to STAT5, ultimately leading to cell cycle arrest and apoptosis in FLT3-ITD-driven leukemic cells. AC-4-130 exhibits notable anti-cancer properties and effectively suppresses abnormal STAT5 activity in acute myeloid leukemia (AML), making it a promising therapeutic option [1].
Sorafenib N-oxide is an active metabolite of sorafenib , an inhibitor of Raf-1, B-RAF, and receptor tyrosine kinases. Sorafenib N-oxide inhibits FLT3 that contains the internal tandem duplication mutation (FLT3-ITD; Kd = 70 nM) and inhibits proliferation of MV4-11 acute myeloid leukemia (AML) cells expressing FLT3-ITD (IC50 = 25.8 nM). It is selective for AML cell lines containing FLT3-ITD over lines containing wild-type FLT3 (IC50s = 3.9-13.3 μM). Sorafenib N-oxide is also a linear-mixed inhibitor of the cytochrome P450 (CYP) isoform CYP3A4 (Ki = 15 μM in human liver microsomes).
