Barasertib ( INH34; AZD1152 or AZD1152-HQPA) is a novel, potent, highly selective, orally bioavailable small-molecule Aurora B inhibitor with potential antitumor activity. It inhibits Aurora B with an IC50 of 0.37 nM in a cell-free assay. As a dihydrogen phosphate pro-drug of Barasertib-hQPA, it shows potent in vitro antiproliferative activity and high in vivo antitumor efficacy. Barasertib shows inhibitory effects against a broad range of aurora kinases, including aurora A kinase (AKB), aurora B kinase (ABK), and aurora C kinase (ACK) with inhibition constant (Ki) of 1369 nM, 0.36 nM, and 17.0 nM respectively, as well as the FMS-like tyrosine kinase 3 internal tandem duplication (FLT3-ITD) mutation.
ln Vitro |
In newly isolated leukemia cells, barasertib-HQPA (3 μM, 3 hours) dramatically lowers the expression of phosphorylated variants of histone H3 [1]. In plasma, barasertib-HQPA is quickly transformed into active barasertib-HQPA [2]. In the LNCaP cell line, barasertib-HQPA therapy causes suboptimal cell survival, polyploidy, and cell death [3]. Significant antiproliferative effects caused by barasertib-HQPA are accompanied by polyploid population emergence, which typically results in apoptosis [4].

ln Vivo |
The development and weight of tumors treated with AZD1152 were considerably decreased by barasertib-HQPA (AZD1152, 25 mg/kg) [1]. In human MOLM13 leukemia xenografts, barasertib-HQPA (AZD1152, 5 mg/kg) amplifies the suppression of proliferation caused by vincristine or daunorubicin [1]. Effectively inhibiting human colon, lung, and hematological tumor xenografts in immunodeficient mice, barasertib-HQPA (AZD1152, 10–150 mg/kg/d) (mean tumor growth inhibition range, 55% to z100%; P < 0.05) [2].

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration: mg/mL;
Method for preparing DMSO stock solution: mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation::Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O,mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
