Syk Inhibitor II is a potent, high selective and ATP-competitive Syk inhibitor with an IC50 of 41 nM. Syk Inhibitor II inhibits 5-HT release from RBL-cells with an IC50 of 460 nM. Syk Inhibitor II shows less potent against other kinases and has anti-allergic effect[1].
Syk Inhibitor II (compound 9a) shows less potent against PKCε, PKCβ2, ZAP-70, Btk, and Itk with IC50 values of 5.1 µM, 11 µM, 11.2 µM, 15.5 µM, and 22.6 µM, respectively[1].
Syk Inhibitor II (Compound 9a; 10-100 mg/kg) is subcutaneously administered to mice 30 min before antigen challenge. Syk Inhibitor II inhibits the anaphylaxis reaction dose-dependently with an ID50 value of 13.2 mg/kg[1].
