Cayman AS-041164

The phosphatidylinositol 3-kinases (PI3Ks) are lipid and protein kinases involved in diverse biological processes, including cell growth, migration, and metabolism. AS-041164 is a potent inhibitor of PI3K with selectivity for the class IB isoform PI3Kγ (IC₅₀ = 70 nM), compared to PI3Kα (IC₅₀ = 240 nM), PI3Kβ (IC₅₀ = 1.45 μM), and PI3Kδ (IC₅₀ =1.70 μM). When tested at 1.0 μM, it shows little or no activity against 38 other common kinases. When given orally to mice, AS-041164 shows a pharmacokinetic profile that is similar to the general PI3K inhibitor LY294002 but is three times more potent (ED₅₀ = 27.4 mg/kg for AS-041164 versus 81.6 mg/kg for LY294002) in blocking neutrophil recruitment induced by RANTES.
