Solvent & Solubility
DMSO : 150 mg/mL (284.61 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 2 years; -20°C, 1 year (sealed storage, away from moisture). When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.

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 (4.74 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (4.74 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 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
Protocol
A homogeneous time-resolved fluorescence (HTRF)-based biochemical IC50 assay is used to test for the kinase activity of the three isoforms of Aurora (A, B, and C) in the presence of SNS-314. A biotin-conjugated histone H3 peptide is used as substrate. Aurora-A kinase (7.5 nM) is assayed in 10 mM Tris–HCl pH 7.2, 10 mM MgCl2, 0.1% BSA, 0.05% Tween 20, 1 mM DTT, 120 nM biotinylated peptide ARTKQTARKSTGGKAPRKQLA-GGK-biotin, 6 μM ATP (2×the Km for the enzyme) for 1 h at 25°C. The reaction is stopped with 200 mM EDTA. Aurora-B and Aurora-C are assayed at 5 nM enzyme concentration, 120 nM biotinylated peptide, and 300 lM ATP (29 the Km for the enzymes) for 1 h at 25°C[2].

HCT116 cells are treated with various concentrations of SNS-314 for 96 hours. cells are incubated with BrdU for 2 h at 37°C. Cell proliferation activity is evaluated by chemiluminescence detection of BrdU incorporated in DNA[2].

Mice: Tumor mice are treated with vehicle or SNS-314. Animals are weighed, monitored for signs or symptoms of toxic effects, and measured for tumor volumes twice weekly until an end point is met[2].
