Biological Activity

• Description: AS-252424 is a novel, potent and selective inhibitor of PI3Kγ with IC50 of 33 nM.
• Targets: PI3Kγ; CK2 (casein kinase 2); PI3Kα
• IC50: 33 nM; 20 nM; 935 nM ^[1]
• 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-micromolarIC50 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 [Ca^2+]i, I_Ca and Ca^2+ 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]

Protocol

• Protocol: Kinase Assay ^[1]
• 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.
• Protocol: Cell Assay ^[1]
• Cell Lines: Raw-264 macrophage
• Concentrations: 0.01 nM to 0.1 μM
• Incubation Time: 5 minutes
• Methods: After 3 hours of starvation in serum-free medium, Raw-264 macrophages are pretreated with AS-252424 or DMSO for 30 minutes and stimulated for 5 minutes with 50 nM C5a. PKB/Akt phosphorylation is monitored using phospho-Ser-473 Akt specific antibody and standard ELISA protocols.
• Protocol: Animal Study ^[1]
• Animal Models: Intraperitoneally injecting female C3H mice with thioglycollate (40 ml/kg) to induced a peritonitis mouse model
• Formulation: AS-252424 is dissolved in vehicle (0.5% carboxymethylcellulose/0.25% Tween-20) and adjusted the solution to 10 mL/kg of body weight.
• Doses: 10 mg/kg
• Administration: Oral administration 15 minutes before injection of thioglycollate
