| Bioactivity | PI3Kγ inhibitor 4 is a potent, selective and orally active inhibitor of PI3Kγ, with an IC50 of 40 nM. PI3Kγ inhibitor 4 shows ∼7, 43, and 18-fold selectivity for PI3Kγ over the α, β, and δ isoforms, respectively. PI3Kγ inhibitor 4 can be used for the research of airway inflammation[1]. |
| Invitro | PI3Kγ inhibitor 4 inhibits PI3Kγ and PI3Kα in U937 cells, with IC50s of 120 nM and 6250 nM, respectively[1]. |
| 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[1].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[1]. |
