syk inhibitor ii

Syk inhibitor II, a cell-permeable, ATP-competitive, pyrimidine-carboxamide compound, selectively and reversibly inhibits Syk (IC50 = 41 nM).

Spleen tyrosine kinase (Syk) is a non-receptor tyrosine kinase that, upon phosphorylation, binds to immunoreceptor tyrosine-based activation motifs of FcRγ chains and mediates downstream signaling related to platelet function and inflammation. Syk inhibit

The impact of spleen tyrosine kinase (Syk) signaling might be prominent in lupus because (i) Syk is a shared downstream signaling molecule among circulating immune complex, LPS, and (1→3)-β-D-glucan (BG), and (ii) all of these factors are detectable in the serum of Fc gamma receptor IIb-deficient (FcgRIIb- -) mice with sepsis. Syk inhibition downregulated several inflammatory pathways in FcgRIIb- - macrophages activated with BG + LPS suggesting the potential anti-inflammatory impact of Syk inhibitors in lupus. Indeed, administration of a Syk inhibitor prior to cecal ligation and puncture (CLP) sepsis in FcgRIIb- - mice reduced baseline lupus-induced proinflammatory cytokines and attenuated sepsis severity as evaluated by mortality, organ injury, serum LPS, and post-sepsis serum cytokines.

Syk Inhibitor II dihydrochloride dihydrate is a highly selective, potent, ATP-competitive Syk inhibitor (IC50: 41 nM) that exhibits anti-allergic effects.

SYK-IN-II is an inhibitor of the spleen tyrosine kinase (STK).
