(c) MM primary cells were treated with idelalisib (1 μm), CZC24832 (1 μm) and duvelisib (1 μm) for 72 h and then assessed for apoptosis by PI/Annexin V staining (n=4).
Blood Cancer J, 2017, 7(3):e539. CZC24832 purchased from Selleck.
For protein analysis, polymorphonuclear neutrophils (PMN) were activated with indicated stimuli (anti-TREM-1 antibody, matched control mAb, LPS) for 30 min after preincubated with idelalisib. Proteins were extracted with an urea-based lysis buffer, SDS PAGE was performed and proteins were blotted by a semi-dry process. Protein activation was analyzed by staining of phosphorylated and non-phosphorylated proteins. ß-actin served as loading control.

Effect of PI3Kγ inhibitor on Akt phosphorylation. JVM3 cells were pre-incubated with the indicated concentrations of CZC4832 (in μM) and then stimulated with SDF1α for 10 min. Akt Ser473 phosphorylation and total Akt levels were assessed by Western blot.

|Description||CZC24832 is the first selective PI3Kγ inhibitor with IC50 of 27 nM, with 10-fold selectivity over PI3Kβ and >100-fold selectivity over PI3Kα and PI3Kδ.|
CZC24832 has excellent selectivity to PI3Kγ. Out of the 154 identified lipid and protein kinases and the 922 other proteins, only two off targets (PI3Kβ and PIP4K2C) are detected within a 100-fold selectivity window. Despite the high sequence conservation of the human and rodent class I PI3K isoforms, the potency of CZC24832 for PI3Kγ and PI3Kβ is consistently lower by a factor of 2 to 4 in mice and rats compared to humans, but selectivity windows are largely retained. In the BT system, treatment with CZC24832 results in profound inhibition of IL-17A (IC50 =1.5 μM) as well as of B-cell activation markers such as IL-6 and IgG. In addition, strong inhibition of IL17A production is observed in T-cell systems such as human umbilical vein endothelial cells grown in the presence of TH2 blasts, indicating a general role for PI3Kγ kinase activity in the control of TH17 function. Thus, CZC24832 inhibits TH17 cell differentiation. 
|In vivo||In an IL-8–dependent air pouch model, CZC24832 shows a dose dependent reduction of granulocyte recruitment consistent with the degree of inhibition observed in PI3Kγ-null mice. In a therapeutic collagen induced arthritis (CIA) model, mice treated orally with 10 mg CZC24832 per kg body weight twice per day shows a substantial decrease of bone and cartilage destruction as well as of overall clinical parameters. |
|In vitro||DMSO||5 mg/mL warmed (13.72 mM)|
|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
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.

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.
