FLT3-IN-3 is an effective FLT3 inhibitor, and the IC50s of FLT3 WT and FLT3 D835Y are 13 and 8 nM, respectively.

PROTAC FLT-3 degrader 1 is a PROTAC FLT-3 degrader of internal tandem duplication (ITD)(IC50 0.6 nM),with anti-proliferative activity.

FLT3/ITD-IN-3 (Compound 19) is a potent inhibitor of FLT3-ITD, acting on FLT3D835Y (IC50: 0.3 nM), FLT3 (IC50: 0.4 nM) and FLT3-ITD (IC50: 0.9 nM). FLT3/ITD-IN-3 showed potent inhibition of FLT3 phosphorylation and was effective against the proliferation of AML cells.

Antiproliferative Against-3 (comp 33) demonstrates significant activity against Hela (IC 50 = 0.21 µM), A549 (IC 50 = 0.39 µM), and MCF-7 (IC 50 = 0.33 µM) cell lines. Additionally, it induces apoptosis in a dose-dependent manner by arresting A549 cells in the G1 phase.

PDGFRα/FLT3-ITD-IN-3 (Compound 18d) is a potent inhibitor of PDGFRα (IC50: 0.153 μM), FLT3 (IC50: 0.004 μM) and PDGFRα/FLT3-ITD-IN-3 has the potential to be studied in acute myeloid leukaemia or chronic eosinophilic leukaemia. .

Quizartinib (AC220) is an inhibitor of FLT3 (Kd: 1.6 nM) and demonstrates high selectivity for FLT3 when tested against a panel of 227 additional kinases.

3-Hydroxy Midostaurin (CGP 52421), a PKC412 metabolite, inhibits FMS-like tyrosine kinase-3 (FLT3) autophosphorylation with IC50 values of roughly 132 nM in culture medium and 9.8 μM in plasma. Though less selective, it exhibits greater cytotoxicity compared to PKC412[1].

LY2457546 is a potent and orally bioavailable inhibitor of multiple receptor tyrosine kinases involved in angiogenic and tumorigenic signalling. LY2457546 demonstrates potent activity against targets that include VEGFR2 (KDR), PDGFRβ, FLT-3, Tie-2 and members of the Eph family of receptors. In vivo, LY2457546 inhibited VEGF-driven autophosphorylation of lung KDR in the mouse and rat in a dose and concentration dependent manner. LY2457546 was well tolerated and exhibited efficacy in a 13762 syngeneic rat mammary tumor models. Additionally, LY2457546 caused complete regression of well-established tumors in an acute myelogenous leukemia (AML) FLT3-ITD mutant xenograft tumor model. The unique spectrum of target activity, potent in vivo anti-tumor efficacy in a variety of rodent and human solid tumor models, exquisite potency against a clinically relevant model of AML, and non-clinical safety profile justify the advancement of LY2457546 into clinical testing.

ATH686 is an potent and selective Inhibitor of FLT3.

AKN-028 acetate, a novel tyrosine kinase (TK) inhibitor, is a potent, orally active FMS-like receptor tyrosine kinase 3 (FLT3) inhibitor with an IC 50 value of 6 nM. AKN-028 acetate inhibits FLT3 autophosphorylation. AKN-028 acetate induces dose-dependent cytotoxic response (mean IC 50 =1 μM). AKN-028 acetate induces apoptosis by activation of caspase 3. AKN-028 acetate can be used in research of acute myeloid leukemia (AML) [1].

AKN-028 is an orally active and potent FLT3 tyrosine kinase inhibitor ( IC 50 = 6 nM). AKN-028 causes dose-dependent inhibition of FLT3 autophosphorylation.

3-Hydroxy Midostaurin-D5 (CGP52421-D5) is a deuterium-labeled 3-Hydroxy Midostaurin which is a metabolite of PKC412. PKC412 effectively inhibits FMS-like tyrosine kinase-3 (FLT3) autophosphorylation (IC50s: 132 nM and 9.8 μM in culture medium and plasma).

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

Tandutinib (CT53518) (MLN518, CT53518), an effective FLT3 antagonist (IC50: 0.22 μM), can also inhibit c-Kit and PDGFR, 15-20 fold higher potency for FLT3 versus CSF-1R and >100-fold selectivity for the same target versus FGFR, EGFR, and KDR.
