AS-605240 potassium

AS-605240 (potassium) is an orally active PI3Kγ inhibitor with an IC50 of 8 nM and a Ki of 7.8 nM. It inhibits MCP-1 and CSF1-induced PKB phosphorylation with IC50 values of 0.181 μM and 0.550 μM, respectively. In mouse models of peritonitis induced by RANTES (CCL5) and thioglycolate, AS-605240 (potassium) reduces neutrophil recruitment, showing EC50 values of 9.1 mg/kg and 10 mg/kg. Additionally, AS-605240 (potassium) ameliorates arthritis induced by αCII-IA in mice.
