How to use

In Vitro:

PI3Kγ inhibitor 4 inhibits PI3Kγ and PI3Kα in U937 cells, with IC50s of 120 nM and 6250 nM, respectively.

In Vivo:

PI3Kγ inhibitor 4 (10-20 mg/kg; a single p.o.) dose dependently inhibits the amplitude of the enhanced pause (ΔPenh) response to ovalbumin in a model of airway inflammation. PI3Kγ inhibitor 4 (a single p.o.) exhibits high oral bioavailability (72, 94 and 122%) and Cmax (1.53, 12.2 and 25.2 μM) following oral administration (10, 100 and 300 mg/kg) in rats.
