Description: Hesperadin is a novel, potent and ATP-competitive inhibitor of human aurora B kinase with potential antitumor activity. It inhibits Aurora B with IC50 of 250 nM in a cell-free assay. It markedly reduces the activity of AMPK, Lck, MKK1, MAPKAP-K1, CHK1 and PHK while it does not inhibit MKK1 activity in vivo. Hersperadin shows potent in vitro antiproliferative activity and high in vivo antitumor efficacy.
| ln Vitro |
Hesperadin (10-100 nM) suppresses Aurora kinase-1 (TbAUK1)-mediated phosphorylation of trypanosome histone H3 (TbH3) in a dose-dependent manner, with an IC50 of 40 nM [1]. Hesperadin (0.01-10 μM; 24 or 48 hours) reduces the growth of bloodstream (BF) and procyclic (PF) cultures [1]. Hesperadin (100-200 nM; 24-72 hours) affects cell shape and hinders cell cycle progression, similar to RNAi suppression of TbAUK1 [1].

| ln Vivo |
Hesperadin (20 mg/kg/d; IV) works in concert with temozolomide (TMZ) to extend the survival of xenograft mice[2].

| Cell Assay |
Cell Viability Assay[1]
Cell Types: M110 cells Tested Concentrations: 0.01, 0.1, 1, 10 μM Incubation Duration: 24 hrs (hours) or 48 hrs (hours) Experimental Results: Inhibiting growth of BF cultures with IC50 of 50 nM, while the inhibition of PF growth required approximately 11-fold more Hesperadin, with IC50 of 550 nM. Cell Cycle Analysis[1] Cell Types: M110 cells Tested Concentrations: 100, 200 nM Incubation Duration: 24, 48, 72 hrs (hours) Experimental Results: Had a strong effect on cell growth and mitotic progression at 100-200 nM. |
| Animal Protocol |
Animal/Disease Models: 6weeks old female nude mice injected GBM cells[2]
Doses: 20 mg /kg/d Route of Administration: Iv injection Experimental Results: Increased the survival of xenograft mice models. |

| Additional Infomation |
Hesperadin is an oxindole that is indolin-2-one which is substituted at position 5 by an (ethylsulfonyl)nitrilo group and at position 2 by a methylidene group, which is itself substituted by a phenyl group and a [4-(piperidin-1-ylmethyl)phenyl]amino group. An Aurora B kinase inhibitor, it is used to inhibit chromosome alignment and segregation. It has a role as an Aurora kinase inhibitor. It is a member of oxindoles, a member of piperidines, a sulfonamide, an enamine and a tertiary amino compound.

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (4.84 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (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 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (4.84 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. View More

*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.
