PROTACFLT-3degrader 3 (compound 35) is a PROTAC degrader of FLT. It exhibits antiproliferative activity, with an IC50 value of 7.55 nM in MV4-11 cells.

BPR1J-097) is a novel FLT-3 inhibitor(IC50: 11±7 nM) with promising in vivo anti-tumor activities. It also inhibits FLT-3 D835Y (IC50: 3 nM).

Flt3 Inhibitor IV is a potent ATP-competitive Flt3 inhibitor.

OSI-930, an orally active inhibitor of c-Kit and the vascular endothelial growth factor receptor-2 (VEGFR-2), targets cancer cell proliferation and blood vessel growth (angiogenesis) in tumors.

Desmorpholinyl Quizartinib-PEG2-COOH is a compound featuring an FLT-3 ligand and a PEG-based PROTAC linker. It is employed in the synthesis of PROTAC FLT-3 degrader 1, which serves as a degrader for the FLT-3 internal tandem duplication (ITD) through PROTAC technology. The degrader exhibits an IC50 of 0.6 nM.

BPR1J-097, a new-type small molecule FLT-3 inhibitor(IC50=11±7 nM), is with great anti-tumor activities in vivo.

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.
