产品描述:
Janus kinases (JAKs) are non-receptor kinases that mediate signaling through cytokine receptors, often to members of the signal transducer and activator of transcription family.{20362} CEP-33779 is a potent, orally available inhibitor of JAK2 (IC50 = 1.3 nM).{27702} It shows 65-fold selectivity for JAK2 over JAK3.{27702} In mouse models of systemic lupus erythematosus, CEP-33779 reduces the production of inflammatory cytokines, decreases splenomegaly and lymphomegaly, and extends survival.{27702} It also diminishes inflammatory signaling and improves clinical scores in mice during collagen antibody-induced arthritis and collagen type II-induced arthritis.{27701} CEP-33779 induces regression of established colorectal tumors in mice, reducing angiogenesis and proliferation of tumor cells.{27700}
