AZD1152-HQPA (Barasertib) is a highly potent and selective inhibitor of Aurora with Ki values of 0.36 and 1369 nM for Aurora B and Aurora A respectively.Consistent with inhibition of Aurora B kinase, addition of AZD1152-HQPA to tumor cells in vitro induces chromosome misalignment, prevents cell division, and consequently reduces cell viability and induces apoptosis.
|Cell lines||HL-60 and U937 cells line|
|Preparation method||Proliferation assay.
To evaluate the growth inhibition effects, the sodium 3′-(1-[(phenylamino)-carbonyl-3,4-tetrazolium])-bis (4-methoxy-6-nitro) benzene sulfonic acid hydrate (XTT) assay was performed according to the manufacturer’s instructions (Roche, Indianapolis, IN, USA) with slight modifications.Roche, Indianapolis, IN, USA) with slight modifications. Cell cycle distribution. Flow cytometric analysis was performed to evaluate the cell cycle distribution. The treated samples were fixed in 80% ethanol, stained with 20 lg ⁄mL propidium iodide (Beckman Coulter, Fullerton, CA, USA), and analyzed using FACSCanto II (BD Bioscience, Franklin Lakes, NJ, USA).
|Incubation time||0 h, 24 h, 48 h, and 72 h|
|Animal models||SW620, Colo205, HCT116 human colorectal tumor xenografts in nude mice|
|Formulation||in Tris buffer pH 9.0|
|Body Surface Area (m2)||0.007||0.025||0.15||0.05||0.02||0.5|
|Animal A (mg/kg) = Animal B (mg/kg) multiplied by||Animal B Km|
|Animal A Km|
For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
