Description

NVP-BAG956 is an ATP-competitive PI3K inhibitor with IC50s of 34, 56, 112 and 444 nM for PI3Kδ, PI3Kα, PI3Kγ and PI3Kβ, respectively.

Target

PI3Kδ:35 nM (IC50)

PI3Kα:56 nM (IC50)

PI3Kγ:117 nM (IC50)

PI3Kβ:446 nM (IC50)

PDK1:240 nM (IC50)

VEGFR1:2.56 μM (IC50)

In Vitro

NVP-BAG956 also inhibits PDK1 with an IC50 of 240/260 nM. NVP-BAG956 also inhibits VEGFR1 with an IC50 of 2.56±0.56 μM. NVP-BAG956 blocks phosphorylation of PKB/Akt in A2058 cells with an IC50 value of 67±25 nM. Inhibition of PKB/Akt phosphorylation correlated with loss of A2058 cell proliferation for NVP-BAG956 (IC50=290±20 nM). In the presence of NVP-BAG956, A2058 cells are only able to exit G2-M and then remain in G1. The p27 Kip1 expression is clearly induced by NVP-BAG956 in A2058 cells but not in C32 cells[1].

Cell Assay

One day after plating (7×103 cells/cm2), melanoma cells (A2058, B16F1, B16F10, C32, HBL, Malme, Malme3M, NA8, SKMel2, SKMel23, A375, Hs294T, WM35, and 1205lu cells) are exposed to LY294002 (25 μM), Wortmannin (500 nM), NVP-BAG956 (1 μM), NVP-BBD130 (1 μM), NVP-BEZ235 (1 μM), and ZSTK474 (1 μM), and Rapamycin (100 nM). Compound concentrations are set 2 log units above the IC50 in vitro to ensure full PI3K inhibition, except for the μM inhibitor LY294002. Cells are trypsinized and counted, and the volume is quantified using a Casy Counter and Analyser. To determine the nuclear volume, cells are resuspended in CASYton containing 0.5% Triton X-100, followed by repetitive pipetting (8×), before volume measurements[1].
