|Description||AS-604850 is a selective, ATP-competitive PI3Kγ inhibitor with IC50 of 250 nM, over 80-fold selectivity for PI3Kγ than PI3Kδ/β, and 18-fold more selective for PI3Kγ than PI3Kα.|
AS-604850 is ATP-competitive PI3Kγ inhibitor with Ki values of 0.18 μM. AS-604850 is isoform selective inhibitor of PI3Kγ with over 30-fold selectivity for PI3Kδ and β, and 18-fold selectivity over PI3Kα. (PI3Kα: IC50 = 4.5 μM, PI3Kγ and β: IC50 > 20μM) AS-604850 is capable of inhibiting C5a-mediated PKB phosphorylation in RAW264 mouse macrophages with an IC50 with 10 μM. AS-604850 blocks MCP-1-mediated chemotaxis in Pik3cg +/+ monocytes in a concentration- dependent manner, with an IC50 of 21 mM, but dosn't affect chemotaxis in Pik3cg-/- cells, indicating that AS-604850 acts through PI3Kγ.  AS-604850 diminishes glycochenodeoxycholate (GCDC) induced Akt-phosphorylation and apoptosis in rat hepatocytes. AS-604850 diminishes bile salt-induced apoptosis in HepG2 Ntcp and Huh7-Ntcp cells.  AS604850 causes a concentration-dependent suppression of chemotactic responses of EoL-1 cells and blood eosinophils to platelet-activating factor (PAF). 
|In vivo||AS-604850 reduces RANTES-induced peritoneal neutrophil recruitment with a ED50 of 42.4 mg/kg. In the thioglycollate-induced peritonitis model, oral administration of 10 mg/kg AS-604850 results in a 31% reduction of neutrophil recruitment. |
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 γATP, 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.
|In vitro||DMSO||57 mg/mL (199.84 mM)|
|Ethanol||5 mg/mL (17.53 mM)|
|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
0.5% CMC+0.25% Tween 80
For best results, use promptly after mixing.
* 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.

1.Please make sure the liquid is clear before adding the next solvent.
2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
