製品説明 Alisertib (MLN8237)は、1.2nMのIC50による選択的なオーロラA阻害剤です。
ターゲット Aurora A
IC50 1.2 nM [1]
In vitro試験 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 dexamethasone, as well as additive effect with doxorubicin and bortezomib. [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 cisplatin (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試験 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]
臨床試験 A Phase II study of MLN8237 for treatment of patients with ovarian, fallopian tube, or peritoneal carcinoma has been completed.
特集 First orally available inhibitor of Aurora A.

キナーゼアッセイ: [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.

細胞株 MM1.S, MM.1R, LR5, RPMI 8226, DOX40, OPM1, OPM2, INA6, and U266
濃度 Dissolved in DMSO, final concentrations ~10 μM
反応時間 24, 48, and 72 hours
実験の流れ 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 fluorescein isothiocyanate-annexin V and PI. Apoptotic cells are determined by flow cytometric analysis using BDFACS-Canto II and FlowJo software.

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.

Results Depletion of PPP6C resulted in a twofold increase in the pT288 form of Aurora A at prometaphase and metaphase spindles compared with control cells, and addition of 10 nM MLN8237 reversed this increase (Fig. A). Importantly, this partial Aurora A inhibition with 10 nM MLN8237 also reduced the micronucleation seen in PPP6C-depleted cells from 40 to 5% (Fig. B).

Results MLN8237 treatment lasted 4 hours and yielded the induction of spindle abnormalities. Spindles with multiple poles represented 15-20 % of all PM/Ms in M LN8237-treated cultures, comparable to the occurrence in Aurora-Ai cultures. When MON was added, Eg5 was inhibited, and the generation of spindles with fragmented poles in MLN8237-treated cultures was abolished, with a parallel increase in mono polar figures.
