Gandotinib (formerly also known as LY2784544) is a novel, potent and selective JAK2 (Janus kinase) inhibitor with potential antitumor activity. It inhibits JAK2 with an IC50 of 3 nM, and shows 8- and 20-fold selectivity for JAK2 over JAK1 and JAK3. It shows potent in vitro antiproliferative activity and high in vivo antitumor efficacy. Gandotinib effectively inhibited JAK2V617F-driven signaling and cell proliferation in Ba/F3 cells (IC50=20 and 55 nM, respectively). In vivo, Gandotinib effectively inhibited STAT5 phosphorylation in Ba/F3-JAK2V617F-GFP ascitic tumor cells and significantly reduced Ba/F3-JAK2V617F-GFP tumor burden in the JAK2V617F-induced MPN model.
ln Vitro |
Gandotinib (LY2784544) is a strong, ATP-competitive, and selective inhibitor of the tyrosine kinase known as Janus kinase 2 (JAK2). In Ba/F3 cells, LY2784544 potently suppresses JAK2V617F-driven signaling and cell proliferation (IC50=20 and 55 nM, respectively). By contrast, Gandotinib (LY2784544) has a substantially lower potency (IC50=1183 and 1309 nM, respectively) at suppressing interleukin-3-stimulated wild-type JAK2-mediated signaling and cell proliferation. Interestingly, geldotinib (LY2784544) exhibits relatively little efficacy against IL-3-activated wild-type JAK2 signaling, with an IC50 of 1183 nM, but potently inhibiting JAK2V617F signaling (IC50 = 20 nM). Gandotinib (LY2784544) is a strong inhibitor of the proliferation of IL-3-stimulated wild-type JAK2 expressing Ba/F3 cells (IC50=1309 nM). LY2784544 inhibits the proliferation of JAK2V617F-expressing cells (IC50=55 nM) and is significantly less. In the NK-92 JAK3/JAK1 heterodimer assay (942 nM), ganditinib (LY2784544) exhibited the required threshold selectivity and is potent in the cell-based TF-1 JAK2 assay (IC50=45 nM)[1].

ln Vivo |
Gandotinib (LY2784544) considerably (P<0.05) lowers the tumor burden of Ba/F3-JAK2V617F-GFP in the JAK2V617F-induced MPN model (TED50=13.7 mg/kg, twice daily) and efficiently inhibits STAT5 phosphorylation in Ba/F3-JAK2V617F-GFP (green fluorescent protein) ascitic tumor cells (TED50=12.7 mg/kg)[1].

Additional Infomation |
Gandotinib is a member of pyridazines.
Gandotinib has been used in trials studying the treatment of Myelofibrosis, Polycythemia Vera, Primary Myelofibrosis, Thrombocythemia, Essential, and Myeloproliferative Disorders, among others. Gandotinib is an orally bioavailable imidazopyridazine and inhibitor of Janus kinase 2 mutant V617F (JAK2V617F), with potential antineoplastic activity. Upon oral administration, gandotinib selectively and competitively inhibits the activation of JAK2V617F, which may result in the inhibition of the JAK-STAT signaling pathway and the induction of apoptosis in JAK2V617F-expressing tumor cells. JAK2V617F has a substitution of phenylalanine for valine at amino acid position 617 and plays a key role in tumor cell proliferation and survival. |

Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (5.32 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (5.32 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.  (Please use freshly prepared in vivo formulations for optimal results.) |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
