MLN82379 (Alisertib) is a second-generation, orally bioavailable, highly selective small molecule inhibitor of the serine/threonine protein kinase Aurora A kinase with potential antineoplastic activity. MLN8237 (Alisertib) binds to and inhibits Aurora A kinase, which may result in disruption of the assembly of the mitotic spindle apparatus, disruption of chromosome segregation, and inhibition of cell proliferation.
|Cell lines||HCT-116, SW480, DLD-1, H460, MDA-MB-231, PC3, SKOV3 cell lines|
|Preparation method||BrdU in vitro cell proliferation assay Thirteen tumor cell lines treated with increasing concentrations of alisertib over 96 hours were subjected to 5-bromo-2-deoxyuridine (BrdU) incorporation as a measurement of cellular proliferation. Proliferation of each cell line was measured using the cell proliferation ELISA, BrdU colorimetric kit according to the manufacturer's recommendations (Roche).|
|Animal models||Mice bearing the disseminated, CD20-positive, non-Hodgkin's lymphoma model OCI-LY19|
|Formulation||10% 2-hydroxypropyl-β-cyclodextrin and 1% sodium bicarbonate|
|Dosages||20 mg/kg twice daily or 30 mg/kg once daily|
|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.

|Incubation Time||48 h|
|Results||Treatment with two other aurora kinase inhibitors, AZD1152 and MLN8237, demonstrated similar results (Fig. 7d).|
