  • A, cell viability assay for mouse rhabdomyosarcoma cultures treated with various doses of NVP-AEW541 and immunoblot showing expression levels of Igf1r in mouse rhabdomyosarcoma primary cell cultures (U20325 and U21089) compared with the mouse myoblast cell line C2C12. B, anchorage-dependent colony formation assay showing increased inhibition of colony formation by mouse rhabdomyosarcoma cultures compared to mouse myoblast cell line C2C12 on treatment with increasing doses of NVPAEW541. C, anchorageindependent colony formation by mouse rhabdomyosarcoma cultures (U20325) is inhibited on treatment with NVP-AEW541, indicated by a decrease in colony size. The scale bar represents 50mm. The number of colonies formed in soft agar also is reduced on treatment with NVP-AEW541. D, Western blot showing decrease in the phosphorylation of Igf1r, P70 S6 kinase, IRS1, Akt, Mapk, and Shc on treatment of the mouse rhabdomyosarcoma primary cell cultures (U20325) with increasing amounts of NVPAEW541.

    A, treating the mouse rhabdomyosarcoma primary cell cultures (U20325) with increasing amount of NVP-AEW541 induces cell cycle arrest in the G1 phase. B, at moderately high concentrations of NVP-AEW541, the mouse rhabdomyosarcoma cells (U20325) show increased apoptosis as evident by the presence of cleaved caspase-3 at 5 mmol/L (but not at 2 mmol/L, unpublished data). C, representative (median) images of luminescence emitted by rhabdomyosarcoma primary cell cultures grown on quail CAM and being treated with DMSO, imatinib, and NVP-AEW541. The images are displayed with a minimum–maximum scale of 2 106 to 2 107 photons/s/cm2/steradian. D, graphical representation of the intensity of bioluminescence signal emitted by rhabdomyosarcoma primary cell cultures grown on quail CAM that were being treated with DMSO, imatinib (100 mmol/L), or NVPAEW541(10 mmol/L).

  • Combination of NVP-AEW541 and lapatinib cooperatively inhibits the growth of NVP-AEW541 resistant murine rhabdomyosarcoma primary cell cultures with Igf1r/Her2 complexes. Cell viability assay for Naïve, untreated (U20325; A) and NVP-AEW541 innately resistant mouse rhabdomyosarcoma primary culture (U44676; B) treated with varying concentrations of NVP-AEW541, lapatinib, or a combination of both. Naïve cells (U20325) were sensitive to NVP-AEW541, but lapatinib had no cooperativity. In contrast, NVP-AEW541 at moderate doses increased cell growth in resistant cell cultures (U44676). However, this paradoxical effect was reduced by the addition of lapatinib, although lapatinib treatment alone had very little effect. C, the NVP-AEW541 resistant primary tumor cell line (U44676) was treated with DMSO, 5mmol/L lapatinib, 5 mmol/L NVP-AEW541, and a combination of 5 mmol/L NVP-AEW541 t lapatinib for 25 minutes and Western blot analysis was done on lysates for p-Igf1r and p-Her2.

NVP-AEW541 also inhibits InsR, Tek, Flt1 and Flt3 with IC50 of 140 nM, 530 nM, 600 nM and 420 nM in purified kinases/recombinant kinase domains assay. NVP-AEW541 is more selective and shows 27-fold more potent than InsR at the cellular level. NVP-AEW541 suppresses the IGF-I-mediated survival, soft agar and proliferation of MCF-7 cells with IC50 of 0.162 μM, 0.105 μM and 1.64 μM, respectively. NVP-AEW541 also reduces the level of phospho-IGF-1R and phospho-PKB in NWT-21 cells. [1] NVP-AEW541 shows growth inhibitory effect on TC-71 musculoskeletal sarcoma cells in low-serum medium as well as in 10% FBS–containing medium. NVP-AEW541 inhibits cell cycle progression and induces specific G1 arrest in sarcoma cell lines (TC-71, SK-N-MC, SaoS-2, RD/18 and RH4). [2] NVP-AEW541 could inhibit the growth of human neuroblastoma cells with IC50 of 0.4-6.8 μM. An increase in the hypodiploid fraction and the depletion of the S and G2-M compartments could be detected in these cell lines. NVP-AEW541-driven inhibition of IGF-1R causes a reduction of phosphorylation of Akt, but not of Erk1 and Erk2 in neuroblastoma cells. [3] NVP-AEW541 inhibits glioma cell growth and disrupts the autocrine loop initiated by HIF1α stabilization. [4] A recent study shows that NVP-AEW541 suppresses the proliferation and viability of PC3, DU145, and 22Rv1 prostate cancer cells, without necessarity of associated cell death. NVP-AEW541 decreases phospho-Akt levels in 22Rv1 and DU415 cells but not PC3 cells, without affecting total Akt levels, which shows that PTEN status could determine the effectiveness of NVP-AEW541 with essential Akt. NVP-AEW541-induced radiosensization is dependent on Akt activation status. NVP-AEW541 could increase the H2AX phosphorylation (a measure of DSBs) in PC3, DU145, and 22Rv1 cells. [5]

In vivo NVP-AEW541 (50 mg/kg, p.o.) results in abrogation of basal and IGF-I-induced receptor, and PKB and MAPK phosphorylation, with T/C value of 14% in the NWT-21 tumor xenograft. [1] NVP-AEW541 (50 mg/kg) causes tumor shrinkage in both HTLA-230 and SK-N-BE2c xenografts, without signs of systemic toxicity. NVP-AEW541 could inhibit tumor invasion both in Matrigel-coated chambers and in HTLA-230 xenografts. [3]


Kinase Assay:[1]

In vitro kinase assays:

NVP-AEW541 is dissolved in DMSO (10 mM) and stored at -20 °C. Dilutions are freshly made in DMSO/water 1:1. The final concentration of DMSO in the enzyme assays is <0.5 %. The protein kinase assays are carried out in 96-well plates at RT and terminated by the addition of 20 μL of 125 mM EDTA. Subsequently, 30 μL (c-Abl, c-Src, IGF-1R) of the reaction mixture are transferred onto Immobilon-PVDF presoaked for 5 min with methanol, rinsed with water, then soaked for 5 min with 0.5 % H3PO4 and mounted on vacuum manifold. After spotting all samples, vacuum is connected and each well rinsed with 200 μL 0.5 % H3PO4. Membranes are removed and washed 4× on a shaker with 1.0 % H3PO4, once with ethanol. After drying, mounting in Packard TopCount 96-well frame, and adding of 10 μL/well of Microscint, membranes are counted. IC50 values are calculated by linear regression analysis of the percentage inhibition of NVP-AEW541 in duplicate, at four concentrations (usually 0.01, 0.1, 1, and 10 μM). One unit of protein kinase activity is defined as 1 nmol of 33P transferred from [γ33P]ATP to the substrate protein per minute per mg of protein at 37 °C.

  • Incubation Time: 72 hours
  • Method: Between 3 × 103 and 6 × 103 cells/well are seeded in 96-well plates with a total media volume of 100 μL/well. Increasing concentrations of NVP-AEW541 is added 24 hours thereafter in quadruplicate. 72 hours later, cells are fixed by addition of 25 μL/well Glutaraldehyde (20%) and incubation for 10 min at RT. Cells are then washed 2× with 200 μL/well H2O and 100 μL Methylene Blue (0.05%) is added. After incubation for 10 min at RT, cells are washed 3× with 200 μL/well H2O. 200 μL/well HCl (3%) is added, and following incubation for 30 min at RT on a plate shaker, absorbance is measured at 650 nm.
