  • Effects of AS252424 on KL-induced cPLA 2 phosphorylation in BMMCs. BMMCs were pre-incubated with AS252424 for 1 h followed by stimulation with KL for 15 min. The phosphorylation of cPLA 2 was evaluated via immunoblot analysis. Results are representative of three independent experiments.*P<0.05, **P<0.01, ***P<0.001 and ### P<0.001, compared with BMMCs with KL induction but without pretreatment by AS252424.

Description AS-252424 is a novel, potent PI3Kγ inhibitor with IC50 of 30 nM in a cell-free assay with 30-fold selectivity for PI3Kγ than PI3Kα, and low inhibitory activity towards PI3Kδ/β.

In vitro

AS-252424 is a furan-2-ylmethylene thiazolidinedione as a selective ATP-competitive PI3Kγ inhibitor with IC50 with 33 nM. AS-252424 shows reduced potency on PI3Kα with an IC50 with 935 nM. When screening against 80 different Ser/Thr and Tyr kinases, AS-252424 doesn't show significant inhibit towards any of them at 10 μM except for CK2. AS-252424 inhibits C5a-mediated PKB/Akt phosphorylation in a concentration- dependent manner with submicromolar or low-micromolar IC50 value. AS-252424 inhibits MCP-1-mediated chemotaxis in wild-type primary monocytes in a concentration-dependent manner with an IC50 value of 52 μM, as well as in the monocytic cell line THP-1 with an IC50 value of 53 μM. [1] AS252424 specifically blocks proliferation in the pancreatic cancer cell lines HPAF and Capan1, as assessed by cell counting. [2] A recent research indicates 100 nM of AS-252424 significantly reduces [Ca2+]i, ICa and Ca2+ transients in HL-1 cardiomyocytes. [3]

In vivo Oral administration of AS-252424 at 10 mg/kg results in moderate reduction of neutrophil recruitment (35%), almost matching the result observed in PI3Kγ-deficient mice. [1]


Kinase Assay:[1]
- Collapse

In vitro PI3Kγ Kinase Assay:

Human PI3Kγ (100 ng) is incubated at RT with kinase buffer (10 mM MgCl2, 1 mM β-glycerophosphate, 1 mM DTT, 0.1 mM Na3VO4, 0.1% Na Cholate and 15 M ATP/100 nCi γ[33]ATP, final concentrations) and lipid vesicles containing 18 M PtdIns and 250 M of PtdSer (final concentrations), in the presence of AS-252424 or DMSO. Kinase reaction is stopped by adding 250 g of Neomycin-coated Scintillation Proximity Assay (SPA) beads and preceded.
