Fig. 5.A, inhibition of VEGF-mediated uterine edema. Compounds were administered intravenously at the indicated dose 30 min before estradiol challenge. Uterine edema was assessed 2 h thereafter. Inhibition > 35% of the response was significantly different from vehicle-treated group (P < 0.05). ED50(milligrams per kilogram) is shown within parentheses. Values are expressed as mean  S.E.M., n= 6 per group. IV, intravenously. B, induction of plasma PLGF after treatment with ABT-348. Mice-bearing tumors derived from a human NSCLC cell line (HCC827ER) were treated with 25 mg/kg ABT-348 via subcutaneous osmotic minipump. At the indicated time, plasma samples were obtained and assayed for murine PLGF. Values shown are the mean  S.E. (n = 5 per group). C, representative longitudinal MRI images showing gadolinium contrast enhancement in a rat glioma model with treatment with vehicle, ABT-348 (6.25 mg/kg i.p. b.i.d., every 7 days; two treatment cycles on days 11 and 18 after inoculation), or AZD1152(25 mg/kg i.v., every 4 days; two treatment cycles commencing on days 11 and 18 after inoculation). b, normal brain; t, tumor, Tx1, first treatment cycl e; Tx2, second treatment cycle. D,K transas a function of treatment cycle. Values represent the mean  S.E.M., n =12 per group.**, P < 0.01 vs. vehicle.

Dual inhibition of Aurora and SRC kinases specifically eliminates hyperploid cells. Experiment shown is same as a, b, but performed following treatment of OVCAR10 cells with MLN8237 (targeting AURKA) or AZD1152 (targeting AURKB);

The alamarBlue assay revealed that AURKB inhibition with AZD1152 was effective in NB TICs at EC50 of 1.5 to 4.6 μmol/L, whereas AURKB inhibition was effective in SKPs at 12.4 μmol/L.

p53 phosphorylation by Aurora B. A, p53 reporter construct was co-transfected with the indicated plasmids into H1299 cells and reporter activation was determined as described under "Experimental Procedures". B, U2OS cells and H1299 cells were treated with AZD1152 (AZD) for 12 h at the indicated doses. Cell lysates were harvested and immunoblotted with Bax and actin antibodies. C, U2OS cells were treated with 100 ng/ml nocodazole (noc) overnight, and then shake off cells were harvested, washed with PBS, and reseeded. Approximately 2 h later, cells were either lysated or treated with dimethyl sulfoxide (DMSO) or AZD1152 for another 16 h before harvesting. Cell lysates were immunoblotted with Bax, phospho-H3, and actin antibodies. D, GST-p53 or GST control proteins were incubated with Aurora B protein and analyzed for phosphate incorporation (left panel). Coomassie staining of GSTp53 and GST protein is also shown (right panel). E, In vitro phosphorylation sites of GST-p53 identified by mass spectrometry analysis. F, GST-p53 wild-type and 3A mutant proteins were analyzed in a kinase assay as in B. G, plasmids encoding wild-type or 3A mutant (CMV)-FLAG-p53 were transiently transfected into H1299 cells, with or without Myc-Aurora B (AurB) expression vector. 20 h post-transfection, cells were lysed and subjected to immunoprecipitation (IP) with p53 antibody (fl-393). Precipitates were immunoblotted with antibodies to p53 (DO-1), Thr(P) and Ser(P), as indicated. Vec, vector.

1205Lu cells were treated for 48hours with the indicated concentrations of  AZD1152-HQPA.
