Biochem/physiol Actions

ER-27319 inhibits Syk activation with an IC50 = 10 μM. ER-27319 inhibits Syk by preventing the phosphorylated ITAM domain of FcεRI γ from activating Syk. ER-27319 does NOT inhibit previously activated Syk.
Selective Syk inhibitor. Induces tyrosine phosphorylation of Syk that has been demonstrated as critical for degranulation.
