Phosphatidylinositol 3-kinase (PI3K) catalyzes the phosphorylation of phosphatidylinositol at the three position to produce the second messengers PtdIns-(3,4)-P2 and PtdIns-(3,4,5)-P3.1,2,3 PI3Kγ is a class 1B PI3K that is composed of a p110 catalytic subunit and a p101 or p84 regulatory subunit, whereas PI3Kα, β, and δ are class 1A enzymes composed of p110 and p85 subunits4 AS-605240 is an orally active inhibitor of PI3-kinase γ that suppresses joint inflammation in murine models of rheumatoid arthritis.5 It inhibits human recombinant PI3Kγ, α, β, and δ in an ATP-competitive manner with IC50 values of 8, 60, 270, and 300 nM, respectively.5 AS-605240 inhibits C5a-mediated phosphorylation of protein kinase B in RAW 264 cells with an IC50 value of 90 nM. In vivo, AS-605240 reduced RANTES-induced peritoneal neutrophil recruitment in a murine model of leukocyte chemotaxis with an ED50 value of 9.1 mg/kg.
