2、pared with Aurora A which has an IC50 of 1.368 M.Barasertib-HQPA (AZD2811) has even less activity against 50 other serine-threonine and tyrosinekinases including FLT3, JAK2, and Abl. Barasertib-HQPA (AZD2811) inhibits the proliferation of hematopoieticmalignant cells such as HL-60, NB4, MOLM13, PALL

3、-1, PALL-2, MV4-11, EOL-1, THP-1, and K562 cells with IC50 of 3-40 nM, displaying appr 100-fold potency than another Aurora kinase inhibitor ZM334739 which has IC50 of 3-30 M.Barasertib-HQPA (AZD2811) inhibits the clonogenic growth of MOLM13 and MV4-11 cells with IC50 of 1 nM and 2.8nM, respectively

4、, as well as the freshly isolated imatinib-resistant leukemia cells with IC50 values of 1-3 nM, moresignificantly compared with bone marrow mononuclear cells with IC50 values of 10 nM. Barasertib-HQPA (AZD2811)induces accumulation of cells with 4N/8N DNA content, followed by apoptosis in a dose- and

5、 time-dependentmanner2. Barasertib-HQPA (AZD2811) treatment induces defective cell survival, polyploidy, and cell death in LNCaPcell line. AZD1152-HQPA also decreases expression of AR3.體內研究 AZD1152 (10-150 mg/kg/day) significantly inhibits the growth of a variety of human solid tumor xenografts, inc

Administration of AZD1152 (25 mg/kg) alonemarkedly suppresses the growth of MOLM13 xenografts, confirmed by the observation of necrotic tissue withinfiltration of phagocytic cells2.PROTOCOLCell Assay 2 Cells are exposed to various c

7、oncentrations 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

8、apoptosis ismeasured by annexin VFITC apoptosis detection kit.MCE has not independently confirmed the accuracy of these methods. They are for reference only.Animal Human tumor xenografts are established by s.c. injecting 100 to 200 L tumor cells (between 1106 and 1107 cellsAdministration 2 mixed 50:

9、50 with Matrigel) on the flank. Animals are randomized into treatment groups (n=8-11 per group) whentumors reach a defined palpable size (0.2-0.3 cm3 and 0.5-1 cm3 for mice and rats, respectively). AZD1152 isprepared in Tris buffer (pH 9) and administered either as a bolus injection (i.v. or i.p.) o

Statistical analysis of any change in tumor volume is carried out using a Studentsone-tailed t test (P value of 0.05 is considered to be statistically significant).MCE has not independently conf
