Description G-749 is a novel and potent FLT3 inhibitor with IC50 of 0.4 nM, 0.6 nM and 1 nM for FLT3 (WT), FLT3 (D835Y), and Mer, respectively, showing lower potency against other tyrosine kinases.

In vitro

In FLT3-WT-bearing RS4-11 cells and FLT3-ITD-harboring MV4-11 and Molm-14 cells, G-749 potently inhibits autophosphorylation of FLT3 with IC50 of ≤8 nM. In leukemia cells, G-749 shows antiproliferative activity by inducing apoptosis. In BaF3 cell lines that stably express FLT3-ITD/N676D, FLT3-ITD/F691L, FLT3-D835Y, or FLT3-D835Y/N676D, G-749 shows strong inhibitory activity with IC50 of <10 nM, and thus overcomes drug resistance. In blasts of AML patients, G-749 also exhibits potent antileukemia activity. [1]

In vivo In MV4-11 xenograft mice, G-749 (30 mg/kg p.o.) effectively inhibits the FLT3 pathway and significant inhibits tumor growth. In an orthogonal model of bone marrow engraftment using Molm-14 cells, G-749 (20 mg/kg p.o.) also inhibits tumor growth and increases survival. [1]
