Description

R112 is a fast and reversible inhibitor of spleen tyrosine kinase (Syk) kinase. R112 inhibits Syk kinase activity with an IC50 value of 226 nM and a Ki value of 96 nM. R112 inhibits IgE-FcεRI signaling pathway. R112 can be used for the research of allergic rhinitis[1].

IC50 & Target

IC50: 226 nM (Syk kinase)[1]

In Vitro

R112 (0.001-10 μM; 1 h) dose-dependently inhibits anti-IgE-mediated tryptase release and histamine release with EC50s of 0.353 and 0.28 μM, inhibits histamine release by basophils stimulated with an EC50 value of 0.49 μM, inhibits secretion of LTC4, TNF-α, GM-CSF and IL-8 with EC50s of 0.115, 2.01, 1.58 and 1.75 μM, respectively[1].
R112 (0-10 μM; 40 min) inhibits Syk target LAT (Y191) phosphorylation[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
