Mechanism of Action

Information	Alisertib (MLN8237) is a potent and highly selective Aurora A kinase inhibitor. It affects DNA damage, PI3K/AKT, and cGAS/STING signaling pathways, by blocking AURKA phosphorylation and inducing G2/M cell cycle arrest, thereby inhibiting tumor cell proliferation and promoting apoptosis and senescence.

Frequently Asked Questions

Question 1:
What is the suggested formulation of this compound for mouse injection(i.p.)?

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration _(start) x Volume _(start) = Concentration _(final) x Volume _(final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

*When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).
