生物活性 | Barasertib (AZD1152), a pro-drug of Barasertib-hQPA, is a highly selectiveAurora Binhibitor with anIC50of 0.37 nM in a cell-free assay. Barasertib (AZD1152) induces growth arrest andapoptosisincancercells[1]. |

体外研究 (In Vitro) | Barasertib-HQPA (3 μM, 3 hours) significantly decreases expression of the phosphorylated forms of histone H3 in freshly isolated leukemia cells[1]. Barasertib-hydroxyquinazoline pyrazol anilide (HQPA)] is converted rapidly to the active Barasertib-HQPA in plasma[2]. Barasertib-HQPA is used for the in vitro experiments[3]. Barasertib-HQPA induces a marked anti-propliferative effect accompanied by the appearance of a polyploid population, which in most cases led to apoptosis[4].

体内研究 (In Vivo) | Barasertib (AZD1152, 25 mg/kg) markedly suppresses the growth and weights of AZD1152-treated tumors[1]. Barasertib (AZD1152, 5 mg/kg) enhances the ability of vincristine or daunorubicin to inhibit the proliferation of human MOLM13 leukemic xenografts[1]. Barasertib (AZD1152, (10-150 mg/kg/d) potently inhibited the growth of human colon, lung, and hematologic tumor xenografts (mean tumor growth inhibition range, 55% to z100%; P< 0.05) in immunodeficient mice[2].
Animal Model: | Female immune-deficient BALB/c nude mice (MOLM13 cells injected)[1]. | Dosage: | 5 or 25 mg/kg. | Administration: | Intraperitoneal injection 4 times a week or every another day. | Result: | Inhibited the growth of human MOLM13 cells growing as xenografts using an immunodeficient murine model. |
