Based on 3 publication(s) in Google Scholar
LY3295668 (AK-01) is a highly specific and orally active inhibitor of Aurora-A kinase with a Ki values for AurA and AurB of 0.8 nM and 1038 nM respectively. LY3295668 can effectively inhibit the autophosphorylation of AurA, induce mitotic arrest and apoptosis. LY3295668 avoids the formation of polyploids related to AurB inhibition. LY3295668 can be used for the study of small cell lung cancer.

Aurora A 0.8 nM (Ki) |
Aurora B 1038 nM (Ki) |
LY3295668 is a highly specific Aurora-A kinase inhibitor, with Ki values of 0.8 nM and 1038 nM for AurA and AurB, respectively. LY3295668, a highly specific AurA inhibitor, can kill Rb-deficient cancer cells at doses that have minimal effects on normal cells. In a kinome-wide survey, only 5 of 386 kinases are potently inhibited by LY3295668 (<10 nM)[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (5.10 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
