描述 The JAK/STAT3 pathway is activated by various cancer types, including glioma, and blockade of the pathway induces cell death in cancer cells. The Janus family kinases (JAKs), JAK1, JAK2, JAK3, and TYK2, are involved in cell growth, survival, development, and differentiation of a variety of cells, particularly immune cells and hematopoietic cells. LY2784544 is a potent, selective and ATP-competitive inhibitor of janus kinase 2 (JAK2) tyrosine kinase 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, respectively and shows increased potency for the JAK2 V617F mutation. LY2784544 effectively inhibited JAK2 V617F -driven signaling and cell proliferation in Ba/F3 cells with IC50 of 20 and 55 nM, respectively. In comparison, LY2784544 was much less potent at inhibiting interleukin-3-stimulated wild-type JAK2-mediated signaling and cell proliferation with IC50 of 1183 and 1309 nM, respectively. In a mouse ascitic tumor model with Ba/F3-JAK2 V617F-GFP cells, LY2784544 was administered once by oral gavage at a dose of 2.5, 5.0, 10.0, 20.0, 40.0, or 80.0 mg/kg to severe combined immunodeficiency mice to measure the inhibition of STAT5 phosphorylation. The result demonstrated that LY2784544 possess good inhibiting effect at STAT5 phosphorylation at indicated concentrations. LY2784544 also potently inhibited STAT5 phosphorylation in Ba/F3 cells expressing JAK2V617F across a concentration range from 50 nM–20 μM[3]. LY2784544 discovered in a focused screen at low micromolar concentrations, prevented Tf endocytosis as well as trypanosome proliferation with GI50 1.0-3.1 μM[4].
作用机制 LY2784544 targets the adenosine triphosphate (ATP) binding site at the TK domain, thus affecting both mutated and wild-type kinases.
