Biochem/physiol Actions

NVP-BSK805 is a selective, ATP-competitive (Ki = 0.43 nM) Janus kinase 2 (JAK2) inhibitor (IC50 = 0.58 and 0.56 nM against full-length wild-type and V617F JAK2, respectively) with greatly reduced potency against TYK2, JAK3, JAK1 (IC50 = 10.76, 18.68, 31.63 nM against respective JAK homology domain 1) and >300-fold selectivity over a panel of 36 other kinases. BSK805 potently inhibits STAT5 phosphorylation (by >90% at 100 nM; MB-02 & SET-2 cells) and proliferation in JAK2V617F mutant cultures in vitro (GI50= 39-331 nM; 75% SET-2 growth inhibition at 150 nM) and in Ba/F3 JAK2V617F-bearing mice in vivo (150 mg/kg p.o.). BSK805 daily oral administration is also efficacious against rhEpo-induced splenomegaly and polycythemia in mice (50-100 mg/kg) and rats (25-50 mg/kg) with good pharmacokinetics and oral avilability.

Assumptions that liver immune cells and immunosuppressive pathways are similar to their counterparts in other spaces have led to gaps in our understanding of intrahepatic neoplasm aggressiveness. Myeloid-derived suppressor cells (MDSCs) are potent inhibitors of antitumor immunity and pose a

The JAK/STAT pathway is an attractive target for breast cancer therapy due to its frequent activation, and clinical trials evaluating JAK inhibitors (JAKi) in advanced breast cancer are ongoing. Using patient biopsies and preclinical models of breast cancer, we demonstrate

The recent discovery of an acquired activating point mutation in JAK2, substituting valine at amino acid position 617 for phenylalanine, has greatly improved our understanding of the molecular mechanism underlying chronic myeloproliferative neoplasms. Strikingly, the JAK2(V617F) mutation is found in

Amplifications at 9p24 have been identified in breast cancer and other malignancies, but the genes within this locus causally associated with oncogenicity or tumor progression remain unclear.
