情報 Barasertib (AZD1152-HQPA)は、0.37nMのIC50による非常に選択的なオーロラB阻害剤です。
目標 Aurora B
IC50 0.37 nM [1]
In vitro試験 AZD1152 displays >3000-fold selectivity for Aurora B as compared with Aurora A which has an IC50 of 1.368 μM. AZD1152 has even less activity against 50 other serine-threonine and tyrosine kinases including FLT3, JAK2, and Abl. AZD1152 inhibits the proliferation of hematopoietic malignant cells such as HL-60, NB4, MOLM13, PALL-1, PALL-2, MV4-11, EOL-1, THP-1, and K562 cells with IC50 of 3-40 nM, displaying ~100-fold potency than another Aurora kinase inhibitor ZM334739 which has IC50 of 3-30 μM. AZD1152 inhibits the clonogenic growth of MOLM13 and MV4-11 cells with IC50 of 1 nM and 2.8 nM, respectively, as well as the freshly isolated imatinib-resistant leukemia cells with IC50 values of 1-3 nM, more significantly compared with bone marrow mononuclear cells with IC50 values of >10 nM. AZD1152 induces accumulation of cells with 4N/8N DNA content, followed by apoptosis in a dose- and time-dependent manner. [1]
In vivo試験 Administration of AZD1152 (25 mg/kg) alone markedly suppresses the growth of MOLM13 xenografts, confirmed by the observation of necrotic tissue with infiltration of phagocytic cells. [1] In addition, AZD1152 (10-150 mg/kg/day) significantly inhibits the growth of a variety of human solid tumor xenografts, including colon, breast, and lung cancers, in a dose-dependent manner. [2]
臨床試験 A Phase I study to assess the safety and tolerability of AZD1152-HQPA in combination with low dose cytosine arabinoside (LDAC) in patients with acute myeloid leukaemia (AML) has been completed.

細胞アッセイ: [1]

細胞系 HL-60, NB4, MOLM13, PALL-2, MV4-11, EOL-1, and K562 cells
濃度 Dissolved in DMSO, final concentrations ~100 nM
処理時間 24 or 48 hours
方法 Cells are exposed to various concentrations of AZD1152 for 24 or 48 hours. Cell proliferation is measured by 3H-thymidine uptake (isotope added 6 hours before harvest), and the concentration that induced 50% growth inhibition (IC50) is calculated from dose-response curves. Cell cycle analysis is performed by flow cytometry. Cell apoptosis is measured by annexin V–FITC apoptosis detection kit.

Method ELISA/Kinase Assays
Cell Lines Mice-bearing tumors
Concentrations 25 mg/kg
Incubation Time 0-7 day
Results ABT-348 inhibited the VEGF response with a potency (ED 50 = 0.2 mg/kg i.v.) that is comparable with another potent anti-VEGF agent, ABT-869, which has intrinsic VEGFR2 potency similar to ABT-348 (IC 50 = 4 and 3 nM, respectively). On-target VEGF receptor inhibition was also implicated by the observation that administration of ABT-348 to tumor-bearing mice resulted in increased plasma levels of the proangiogenic PLGF (Fig. B). acute changes in the MRI signal were observed during treatment with ABT-348 (Fig. C). After a sharp decrease in Ktrans that was apparent within 24 h after the first treatment cycle of ABT-348, the MRI signal returned to pretreatment levels by 6 days when reassessed longitudinally, which was reflective of the Q7D-dosing sequence. (Fig. D) the reduction in Ktrans (75%) was similar in magnitude to that previously reported for the selective EGFR/PDGFR inhibitor.

Results Further, although a >4N hyperploid population was induced by treatment of cells with inhibitors selective for AURKA (MLN8257) or AURKB (AZD1152), only the combination of dasatinib with MLN8257 selectively reduced this population of cells.

Results Proliferation of NB TICs is reduced following inhibition of AURKB, showing low micromolar EC50 values (1.5-4.6 μmol/L). In contrast to this, SKPs were less sensitive to AZD1152, exhibiting higher EC50 values (12.4 μmol/L).

Cell Lines U2OS cells, H1299 cells
Concentrations 0-120 nM
Incubation Time 12 h/16 h
Results As shown in Fig. A, whereas wild-type Aurora B efficiently suppressed p53 in a luciferase reporter assay, a kinase-inactive Aurora B mutant (K106R) had a minimal effect on p53 transcriptional activity. In line with this, treatment of U2OS cells, but not H1299 cells, with the Aurora B-specific inhibitor AZD1152 markedly induced Bax expression (Fig. B). As shown in Fig. C, AZD1152 significantly induced Bax expression in the cells released from mitosis, suggesting that Aurora B is required for p53 suppression in G 1 to early S-phase. To determine whether Aurora B directly phosphorylates p53, we performed an in vitro kinase assay using Aurora B protein expressed in insect cells as the kinase source and GST-p53 purified from bacteria as the substrate and confirmed that Aurora B directly phosphorylates p53 (Fig. D).
