AS-252424 is a potent and selective PI 3-kinase p110γ inhibitor (IC50 = 33 nM) shown to be selective for class IB PI 3-kinase-mediated cellular effects. AS-252424 also prevents C5a-mediated phosphorylation of Akt in RAW 264.7 macrophages with an IC50 of 0.23 μM. AS-252424 is an inhibitor of Casein Kinase and PI 3-kinase p110 α.
Sequential activation of class IB and class IA PI3K is important for the primed respiratory burst of human but not murine neutrophils: A.M.
