5.0mg/ml Taking the 1 mL working solution as an example, add 40 μL of 125 mg/ml clarified DMSO stock solution to 500 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 410 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

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.
Targets
Casein Kinase 2 [1]
(Cell-free assay)		 PI3Kγ [1]
(Cell-free assay)		 PI3Kα [1]
(Cell-free assay)
20 nM 33 nM 935 nM
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]

Protocol (from reference)

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.
Cell Assay:[1]
  • Cell lines

    Raw-264 macrophage

  • Concentrations

    0.01 nM to 0.1 μM

  • Incubation Time

    5 minutes

  • Method

    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.
Animal Study:[1]
  • Animal Models

    Intraperitoneally injecting female C3H mice with thioglycollate (40 ml/kg) to induced a peritonitis mouse model

  • Dosages

    10 mg/kg

  • Administration

    Oral administration 15 minutes before injection of thioglycollate
