Biological Activity

Description Alisertib (MLN8237) is a selective Aurora A inhibitor with IC50 of 1.2 nM in a cell-free assay. It has >200-fold higher selectivity for Aurora A than Aurora B. Alisertib induces cell cycle arrest, apoptosis and autophagy. Phase 3.
Targets
Aurora A [1]
(Cell-free assay)
1.2 nM
In vitro

MLN8237 shows >200-fold higher selectivity for Aurora A than the structurally related Aurora B with an IC50 of 396.5 nM, and does not have any significant activity against 205 other kinases. [1] MLN8237 (0.5 μM) treatment inhibits the phosphorylation of Aurora A in MM1.S and OPM1 cells, without affecting the Aurora B mediated histone H3 phosphorylation. MLN8237 significantly inhibits cell proliferation in multiple myeloma (MM) cell lines with IC50 values of 0.003-1.71 μM. MLN8237 displays more potent anti-proliferation activity against primary MM cells and MM cell lines in the presence of BM stroma cells, as well as IL-6 and IGF-1 than against MM cells alone. MLN8237 (0.5 μM) induces 2- to 6-fold increase in G2/M phase in primary MM cells and cell lines, as well as significant apoptosis and senescence, involving the up-regulation of p53, p21 and p27, as well as PARP, caspase 3, and caspase 9 cleavage. In addition, MLN8237 shows strong synergistic anti-MM effect with Hexadecadrol, as well as additive effect with doxorubicin and LDP-341. [2] MLN8237 (0.5 μM) treatment causes the inhibition of colony formation of FLO-1, OE19, and OE33 esophageal adenocarinoma cell lines, and induces a significant increase in the percentage of polyploid cells, and subsequently an increase in the percentage of cells in the sub-G1 phase, which can be further enhanced in combination with NSC 119875(2.5 μM), involving the higher induction of TAp73β, PUMA, NOXA, cleaved caspase-3, and cleaved PARP as compared with a single-agent treatment. [3]
In vivo

MLN8237 significantly reduces the tumor burden with tumor growth inhibition (TGI) of 42% and 80% at 15 mg/kg and 30 mg/kg, respectively, and prolongs the survival of mice compared with the control. [2]
Features First orally available inhibitor of Aurora A.

Protocol (from reference)

Kinase Assay:

[1]
  • Aurora A radioactive Flashplate enzyme assay

    Aurora A radioactive Flashplate enzyme assay is conducted to determine the nature and degree of MLN8237-mediated inhibition in vitro. Recombinant Aurora A is expressed in Sf9 cells and purified with GST affinity chromatography. The peptide substrate for Aurora A is conjugated with biotin (Biotin-GLRRASLG). Aurora A kinase (5 nM) is assayed in 50 mM Hepes (pH 7.5), 10 mM MgCl2, 5 mM DTT, 0.05% Tween 20, 2 μM peptide substrate, 3.3 μCi/mL [γ-33P]ATP at 2 μM, and increasing concentrations of MLN8237 by using Image FlashPlates.
Cell Assay:

[2]
  • Cell lines

    MM1.S, MM.1R, LR5, RPMI 8226, DOX40, OPM1, OPM2, INA6, and U266

  • Concentrations

    Dissolved in DMSO, final concentrations ~10 μM

  • Incubation Time

    24, 48, and 72 hours

  • Method

    Cells are exposed to various concentrations of MLN8237 for 24, 48, and 72 hours. Cells viability is measured using MTT assay, and cell proliferation is measured using 3[H]-thymidine incorporation. For cell cycle analysis, cells are permeabilized by 70% ethanol at -20 °C, and incubated with 50 μg/mL PI and 20 units/mL RNase-A. DNA content is analyzed by flow cytometry using BDFACS-Canto II and FlowJo software. For the detection of apoptosis and senescence, cells are stained with Resorcinolphthalein isothiocyanate-annexin V and PI. Apoptotic cells are determined by flow cytometric analysis using BDFACS-Canto II and FlowJo software.
Animal Study:

  • Animal Models

    Severe combined immune-deficient (SCID) mice inoculated subcutaneously with MM1.S cells

  • Dosages

Customer Product Validation

<p>Alisertib inhibits AURKA and AURKB in a concentration-dependent manner. (a) Alisertib induces G 2 /M delay or genome reduplication. HeLa cells were exposed to buffer or the indicated concentrations of Alisertib. After 24 h, the cells were harvested and analyzed with flow cytometry. The positions of 2N, 4N and 8N DNA contents are indicated. (b) Alisertib delays mitotic exit or induces slippage. HeLa cells stably expressing histone H2B-GFP were exposed to buffer or the indicated concentrations of Alisertib. Individual cells were then tracked for 24 h with time-lapse microscopy. Each horizontal bar represents one cell (n ¼ 50). Key: light gray ¼ interphase; black ¼ mitosis (from DNA condensation to anaphase or mitotic slippage); dark gray ¼ interphase after mitotic slippage; truncated bars ¼ cell death. (c) Different concentrations of Alisertib are involved in delaying mitotic exit and inducing slippage. Live-cell imaging of cells treated with Alisertib was described in panel (b). The duration of mitosis (mean±90% confidence interval) and the percentage of cells that underwent mitotic slippage during the imaging period was quantified. (d) Alisertib promotes apoptosis in a concentration-dependent manner. HeLa cells were incubated with the indicated concentrations of Alisertib for 48 h. The cells were then harvested and analyzed with flow cytometry. (e) Concentration-dependent cytotoxicity of Alisertib. HeLa cells were cultured in the presence of the indicated concentrations of Alisertib for 48 h. The number of live and dead cells was analyzed with trypan blue exclusion assay. (f) Concentration-dependent suppression of long-term survival by Alisertib. HeLa cells were seeded on 60-mm culture plates and grown in the presence of 250 n M or 1 m M of Alisertib. After 24 h, the cells were washed gently and propagated in normal medium for another 10–12 days. Colonies were fixed and stained with crystal violet solution (examples of the plates are shown). Average±s.d. from three independent experiments. (g) Both AURKA and AURKB are inhibited by Alisertib.Mitotic HeLa cells were obtained by exposure to nocodazole for 16 h followed by mechanical shake off. The cells were incubated with the indicated concentrations of Alisertib for 2 h. Lysates were then prepared and activated phospho-AURKAThr288 and AURKBThr232were detected with immunoblotting. The asterisk indicates the position of an AURKB-like protein (the same throughout this study). Uniform loading was confirmed by immunoblotting for actin. In this assay, nocodazole and MG132 (a proteasome inhibitor) were added to prevent the cells from exiting mitosis. Accordingly, the total AURKA and AURKB levels remained constant throughout the experiment. (h) Alisertib prevents activation of AURKA and AURKB. HeLa cells were incubated with the indicated concentrations of Alisertib for 8 h. Nocodazole was then added for another 6 h to trap cells that entered mitosis. Lysates were prepared and analyzed with immunoblotting. Actin analysis was included to assess loading and transfer.</p>
