biological activity | AS-604850 is an effective, selective and ATP competitive PI3Kγ inhibitor with IC50 value of 0.25 μM and Ki value of 0.18 μM. AS-604850 is an isoform selective inhibitor of PI3Kγ, and its selectivity to PI3Kγ is more than 30 times that of PI3Kδ/β and more than 18 times that of PI3Kα. |
target | PI3Kγ 0.25 μM (IC 50 ) PI3Kγ 0.18 μM (Ki) PI3Kα 4.5 μM (IC 50 ) |
in vitro study | AS-604850 inhibits C5a-mediated PKB phosphorylation with an IC 50 of 10 μ m in RAW264 mouse macrophages. AS-604850 blocks PKB phosphorylation induced by MCP-1 and has little or no effect after stimulation with CSF-1 in primary monocytes from Pik3cg +/+ or Pik3cg -/-mICE. AS-604850 (0-30 μ m; 15 minutes; primary monocytes from Pik3cg +/+ mice) treatment inhibits MCP-1-mediated phosphorylation of PKB and its downstream substrates GSK3α and β in a concentration-dependent manner. MCP-1-induced phosphorylation of p44/42 ERK (ERK1/2) MAPKs is also reduced, in a concentration dependent manner in primary monocytes from Pik3cg +/+ mice. Western Blot Analysis Cell Line: Primary monocytes from Pik3cg +/+ mice Concentration: 0 μM, 1 μM, 3 μM, 10 μM, 30 μM Incubation Time: 15 minutes Result: Inhibited MCP-1-mediated phosphorylation of PKB and its downstream substrates GSK3α and β in a concentration-dependent manner. MCP-1-induced phosphorylation of p44/42 ERK (ERK1/2) MAPKs was also reduced, in a concentrationdependent manner in primary monocytes from Pik3cg +/+ mice. |
