Product Description

GSK1070916 (also known as NMI-900 or GSK-1070916A) is a novel, potent, reversible and ATP-competitive inhibitor of Aurora B/C with potential antitumor activity. It inhibits Aurora B/C with IC50 of 3.5 nM/6.5 nM and displays >100-fold selectivity for Aurora B/C over the closely related Aurora A-TPX2 complex. It shows potent in vitro antiproliferative activity and high in vivo antitumor efficacy. GSK1070916 A binds to and inhibits the activity of Aurora kinases B and C, which may result in inhibition of cellular division and a decrease in the proliferation of tumor cells that overexpress the Aurora kinases B and C. Aurora kinases play essential roles in mitotic checkpoint control during mitosis, and are overexpressed by a wide variety of cancer cell types.

Biological Activity I Assay Protocols (From Reference)
ln Vitro
GSK-1070916 has a modest inhibitory impact on Aurora A/TPX2, with a Ki of 492±61 nM, while it significantly inhibits the kinases of Aurora B/INCENP and Aurora C/INCENP, with Ki of 0.38±0.29 and 1.45±0.35 nM, respectively. Additionally, FLT1, TIE2, SIK, FLT4, and FGFR1 are inhibited by GSK-1070916, with IC50 values of 42, 59, 70, 74, and 78 nM, respectively. GSK-1070916 treatment of human lung cancer A549 cells can result in a strong anti-proliferative impact (EC50=7 nM) [1]. GSK-1070916 has been demonstrated to suppress HH3-S10 phosphorylation in all tumor cell lines, with average EC50 values ranging from 8 to 118 nM [2]. The compound also inhibits a panel of tumor cell lines.
ln Vivo
GSK-1070916 injected intraperitoneally (i.p.) suppresses HH3-S10 phosphorylation in a dose-dependent manner in nude mice implanted with human colon tumor (HCT116) xenografts. Upon repeated intraperitoneal (i.p.) administration of GSK-1070916, four out of eight tumor types (lung, A549; colon, HCT116; acute myelogenous leukemia (AML), HL60; and chronic myelogenous leukemia, K562) exhibit complete or partial antitumor activity; three of the eight exhibit stable disease (colon, Colo205; lung, H460; and breast, MCF-7); and one of the eight tumor types (colon, SW620) exhibits tumor growth delay. In general, GSK-1070916 is well tolerated when taken daily[2].
Animal Protocol
Formulated in 2% Cremophor EL, 2% N,N-dimethylacetamide, and 96% acidified water (pH 5.0); 25, 50, or 100 mg/kg; i.p. injection.

*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.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
