Barasertib, previously known as AZD1152-hydroxyquinazoline pyrazol anilide (HQPA), is a potent aurora kinase inhibitor, which is resulted from rapid phosphatase-mediated cleavage of the precursor, AZD1152, in serum following parenteral administration in vivo. It 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. Barasertib has demonstrated anti-tumor activity against a range tumor cell lines including those of leukaemic acute myeloid leukemia (AML) origin.

General tips
We do not recommend long-term storage for the solution, please use it up soon.
Protocol
Cell experiment: [1]
Cell lines
HL-60 cells
Preparation method
The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while.Stock solution can be stored below -20°C for several months.
Reaction Conditions
25 nM, 72 hours
Applications
The cells exhibited increased DNA contents of 4N and 8N, indicative of polyploidy, within 24–48 h of treatment. After 48–72 h, barasertib-HQPA induced apoptotic cell death, as detected by an increased sub-G1 population compared for that of untreated cells. The induction of polyploidy was obvious at 24–48 h, and thereafter, the nuclei showed morphology typical of apoptosis, such as nuclear fragmentation and condensation. These observations were in accordance with the findings of the flow cytometric analysis.
Animal experiment: [2]
Animal models
Female nude mice injected with SW620, Colo205 or HCT116 cells
Dosage form

Applications
In SW620, HCT116 and Colo205 xenografts significant tumor growth inhibitions of 79% (P
Other notes
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.
