  • PI3K inhibitor IPI-145 demonstrated to be effective on ALL-SIL cells,showed an IC50 in the lower micromolar range.

    Dr. Antonino Maria Spartà from University of Bolog. Duvelisib (IPI-145) purchased from Selleck.

  • Inhibition of PI3Kγ or PI3Kδ significantly decreased the migration of JVM3 cells. JVM3 cells were cultured in medium or stimulated for 24 h with CD40L/IL-4 and then incubated with the PI3Kγ-specific inhibitor CZC24832 (2 µM), the PI3Kδ-specific inhibitor idelalisib (1 µM), dual PI3Kδ/γ inhibitor duvelisib (1 µM), or the pan-PI3K inhibitor GDC0980 (1 µM) and subjected to a transwell migration assay. DMSO served as the vehicle control for the inhibitors, while SDF1α (100 ng/ml) served as the chemoattractant (n = 7).

    Leukemia, 2018, 32(9):1958-1969. Duvelisib (IPI-145) purchased from Selleck.

  • MM1s were incubated with increasing doses of duvelisib for 4 h after which protein was extracted. Samples were then analysed for phospho-AKT and phospho-MAPK response using Western blotting. Blots were re-probed for total AKT and MAPK to confirm sample loading.

Effects of duvelisib on the PI3K/Akt pathway in B and T cell lines. EBV-negative B cell lines [BJAB and Akata (-)], EBV-positive B cell lines [Akata (+), Mutu I, LCL, Raji, and P3HR1], and EBV-negative T cell line (Jurkat) were treated without (-) or with 1 or 5 μmol/L duvelisib for 48 h. Cell lysates were then immunoblotted for the indicated proteins involved in PI3K/Akt signaling.

In vivo IPI-145 (10 mg/kg, p.o.) shows well pharmacokinetics with Cmax and AUC of 390 ng/mL and 137 ng•h/mL in mouse and rat. IPI-145 (10 mg/kg) is active in murine DTH model with ~50% ear swelling. IPI-145 (10 mg/kg) demonstrates dose-dependent effect in rat collagen induced arthritis (CIA) model. IPI-145 prevents inflammation and protects joint bone and cartilage in the rat CIA model. IPI-145 (10 mg/kg,QD) demonstrates activity in rat adjuvant induced polyarthritis model. [1]

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.
