CAS#: 1229236-86-5

Description: Gandotinib, also known as LY2784544, is a potent and selective JAK inhibitor. LY2784544 in vitro selectivity for JAK2 was found to be equal or superior to known JAK2 inhibitors. LY2784544 effectively inhibited JAK2V617F-driven signaling and cell proliferation in Ba/F3 cells (IC50=20 and 55 nM, respectively). In vivo, LY2784544 effectively inhibited STAT5 phosphorylation in Ba/F3-JAK2V617F-GFP ascitic tumor cells (TED50=12.7 mg/kg) and significantly reduced (P<0.05) Ba/F3-JAK2V617F-GFP tumor burden in the JAK2V617F-induced MPN model (TED50=13.7 mg/kg, twice daily).

Biological target: Gandotinib (LY2784544) is a potent JAK2 inhibitor with IC50 of 3 nM. Gandotinib (LY2784544) also inhibits FLT3, FLT4, FGFR2, TYK2, and TRKB with IC50 of 4, 25, 32, 44, and 95 nM.
In vitro activity: As JAK2-STAT5 signaling has a role in MPN cell proliferation, LY2784544 was next evaluated in the MTS cell proliferation assay utilizing the same Ba/F3 cells expressing JAK2V617F or IL-3-activated wild-type JAK2. Consistent with findings from the signaling studies, LY2784544 inhibited the proliferation of JAK2V617F-expressing cells (IC50=55 nM) and was markedly less potent as an inhibitor of the proliferation of IL-3-stimulated wild-type JAK2 expressing Ba/F3 cells (IC50=1309 nM) (Table 3).

In vivo activity: Testing of LY2784544 in SCID mice bearing Ba/F3-JAK2V617F-GFP, ascitic tumors demonstrated potent, dose- and exposuredependent inhibition of STAT5 phosphorylation as demonstrated in Figure 4a (FACS histograms and bar graphs) and Figure 4b, respectively.
