LY2784544 is an orally active, ATP-competitive, potent and JAK2-selective janus tyrosine kinase inhibitor (IC50/[ATP] = 2.52 nM/5 μM/JAK2, 19.8 nM/20 μM/JAK1, 48.0 nM/2 μM/JAK3) with little activity toward 79 other kinases. LY2784544 selectively inhibits signaling/proliferation driven by oncogenic JAK2V617F (IC50 = 20/55 nM) over those mediated by wt JAK2 upon IL-3 induction (IC50 = 1183/1309 nM) in Ba/F3 cultures and displays in vivo efficacious in a JAK2V617F-induced murine MPN model (10-80 mg/kg bid po.). LY2784544 is also reported to display Zn-dependent (optimal [Zn+2] = 100 μM) GPR39 agonist activity, but not 11 other GPRs.
Orally active, ATP-competitive, potent and JAK2-selective janus tyrosine kinase inhibitor with additional Zn+2-dependent GPR39 agonist activity.
Antineoplastic platinum agents are used in first-line treatment of ovarian cancer, but treatment failure frequently results from platinum drug resistance. Emerging observations suggest a role of reactive oxygen species (ROS) in the resistance of cancer drugs including platinum drugs. However
Human parasite Trypanosoma brucei proliferates in the blood of its host, where it takes up iron via receptor-mediated endocytosis of transferrin (Tf). Mechanisms of Tf endocytosis in the trypanosome are not fully understood. Small molecule lapatinib inhibits Tf endocytosis in
Owing to the prevalence of the JAK2V617F mutation in myeloproliferative neoplasms (MPNs), its constitutive activity, and ability to recapitulate the MPN phenotype in mouse models, JAK2V617F kinase is an attractive therapeutic target. We report the discovery and initial characterization of
Due to the lack of effective therapies and poor prognosis in TNBC (triple-negative breast cancer) patients, there is a strong need to develop effective novel targeted therapies for this subtype of breast cancer. Inhibition of heat shock protein 90 (HSP90)
In this study, we identified two previously described kinase inhibitors-3-(4-chloro-2-fluorobenzyl)-2-methyl-N-(3-methyl-1H-pyrazol-5-yl)-8-(morpholinomethyl)imidazo[1,2-b]pyridazin-6-amine (LY2784544) and 1H-benzimidazole-4-carboxylic acid, 2-methyl-1-[[2-methyl-3-(trifluoromethyl)phenyl]methyl]-6-(4-morpholinyl)- (GSK2636771)-as novel GPR39 agonists by unbiased small-molecule-based screening using a β-arrestin recruitment screening approach (PRESTO-Tango). We characterized the signaling of LY2784544 and GSK2636771 and compared
Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
