Product Description
Empesertib (also known as BAY 1161909) is a novel, potent, orally bioavailable, and selective inhibitor of serine/threonine kinase Mps1 (monopolar spindle 1) with an IC50 of < 1 nM. Empesertib binds to Mps1 and inhibits its activity, which results in accelerated mitosis, chromosomal misalignment, chromosomal missegregation, destabilization of the mitotic checkpoint complex, and increased aneuploidy. Empesertib has the potential to be antineoplastic. This causes cancer cells that overexpress Mps1 to undergo cell death.
Biological Activity I Assay Protocols (From Reference)
Targets
Mps1 (IC50 = 1 nM)
ln Vitro
Empesertib (BAY1161909) is a very potent Mps-1 inhibitor, showing an IC50 lower than 400 nM in a HeLa cell proliferation assay and an IC50 lower than or equal to 1 nM (more potent than 1 nM) in an Mps-1 kinase assay with a concentration of 1 μM/2 mM ATP.[1]
ln Vivo
Empesertib (BAY1161909) is an extremely potent Mps-1 inhibitor. Its maximum oral bioavailability (Fmax) in rats is greater than 70%, as measured by rat liver microsomes; similarly, its maximum oral bioavailability (Fmax) in dogs is greater than 50%, as measured by dog liver microsomes; and its maximum oral bioavailability in humans is greater than 60%, as measured by human liver microsomes.[1]
Cell Assay
On a 96-well multititer plate, cultured tumor cells are plated at densities of 5000 cells/well (MCF7, DU145, HeLa-MaTu-ADR), 3000 cells/well (NCI-H460, HeLa-MaTu, HeLa), or 1000 cells/well (B16F10) in 200 μl of each of their five growth media supplementsed with 10% fetal calf serum." The test substances are added to the fresh culture medium (200 μl) in the other plates, which has been replaced with varying concentrations (0 μM, as well as in the range of 0.01-30 μM). The cells are incubated for 4 days in the presence of the test substances. After 24 hours, the cells on one plate (the zero-point plate) are stained with crystal violet. Cell proliferation is assessed by staining the cells with crystal violet. To fix the cells, add 20 μl/measuring point of an 11% glutaric aldehyde solution and let it sit at room temperature for 15 minutes. The fixed cells 15 are washed three times with water, and then the plates are dried at room temperature. Staining the cells involves adding 100 μl/measuring point of a 0.1% crystal violet solution (pH 3.0). The plates are dried at room temperature following three rounds of water washing for the stained cells. To dissolve the dye, add 100 μl/measuring point of a 10% acetic acid 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.

*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
