How to use

In Vitro:

AS1810722 (compound 24) inhibits production of IL-4 with an IC50 of 2.4 nM, but shows no effect on production of IFN-γ.

In Vivo:

AS1810722 (compound 24; 0.03-0.3 mg/kg; orally; 30 min before, and 24h and 48 h after OVA exposure) suppress eosinophil infiltration in the lung in a dose-dependent manner in an antigen-induced mouse asthmatic model. AS1810722 inhibits in vitro Th2 differentiation with an IC50 of 2.4 nM without affecting type 1 helper T (Th1) cell differentiation and eosinophil infiltration in an antigen-induced mouse asthmatic model after oral administration.
