Description

General description

A cell-permeable pyrimidine-carboxamide compound that acts as a potent, selective, reversible, and ATP-competitive inhibitor of Syk (IC₅₀ = 41 nM), while affecting PKC_ε, PKC_βII, ZAP-70, Btk, and Itk only at much higher concentrations (IC₅₀ = 5.1, 11, 11.2, 15.5, and 22.6 µM, respectively). Inhibits FcεRI-mediated 5-HT release in RBL-2H3 cells in vitro (IC₅₀ = 460 nM) and passive cutaneous anaphylaxis (PCA) reaction in mice in vivo (ID₅₀ = 13.2 mg/kg, s.c.).

Biochem/physiol Actions
