In vitro	Gandotinib (LY2784544) inhibits IL-3-activated wild type JAK2 with an IC50 of 2.26 μM. Similarly, in the proliferation assay, it shows antiproliferation activity in JAK2 V617F-driven cells with an IC50 of 68 nM, compared to 1.36 μM in wild type JAK2-driven cells and 0.94 μM in JAK3-driven cells. ^[1] Though biochemical assays do not reveal selectivity of this compound for mutant JAK2V617F, it shows higher selectivity for inhibition of JAK2-mediated signaling and induction of apoptosis in Ba/F3 cells expressing JAK2V617F than wild-type cells. ^[2]
In vivo	Gandotinib (LY2784544) significantly inhibits STAT5 phosphorylation in Ba/F3-JAK2 V617F-GFP xenografts with a Threshold Effective Dose 50 (TED50) of 12.7 mg/kg. It also reduces Ba/F3-JAK2 V617F-GFP tumor burden in the JAK2 V617F-induced MPN model with a TED50 of 13.7 mg/kg after oral treatment. This compound has no effect on CD71/Ter119 positive erythroid progenitors in spleens of SCID mice after oral treatment. ^[1]
