SP-96 is a very strong, focused, and non-ATP competitive inhibitor of Aurora B (IC50=0.316 nM) that exhibits >2000 fold selectivity against KIT (IC50=1307.6 nM) and FLT3 (IC50=1475.6 nM) [1]. While SP-96 (0-1 μM; 24 hours) is not promiscuous, it is selective for certain cell lines, as evidenced by its GI50 values of 107 nM, 47.4 nM, 50.3 nM, and 53.2 nM for MDA-MB-468, CCRF-CEM, COLO 205, and A498 cells, respectively[1]. By raising the DNA content and causing the cell volume and nucleus to enlarge, SP-96 (63.2 nM) suppresses the Aurora B activity of H460 cells [1]. The enzyme activity of Aurora B is inhibited by SP-96 (0-2 μM) at an IC50 of 0.316 nM, while Aurora A enzyme activity is inhibited at an IC50 of 18.975 nM. More than 2000-fold selectivity is shown by SP-96 for both KIT (IC50=1307.6 nM) and FLT3 (IC50=1475.6 nM). Moreover, it has an IC50 value of less than 2 μM and inhibits the activity of EGFR, RET, and HER2 receptor tyrosine kinases (RTKs) [1].

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (5.51 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly. (Please use freshly prepared in vivo formulations for optimal results.) |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
