Biochem/physiol Actions

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.

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

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
