Description BAY 1217389 is an effective and selective inhibitor of the monopolar spindle 1 (MPS1) kinase (IC50<10 nM).
Targets&IC50 Mps1:<10 nM
In vitro In biochemical assays, the IC50 value of BAY 1217389 is 0.63±0.27 nmol/L. It shows high selectivity against other kinases and found to bind to PDGFRβ (<10 nmol/L), Kit (between 10 and 100 nmol/L), CLK1, CLK2, CLK4, JNK1, JNK2, JNK3, LATS1, MAK, MAPKAP2, MERTK, p38β, PDGFRα, PIP5K1C, PRKD1, and RPS6KA5 (between 100 and 1,000 nmol/L). In cellular mechanistic assays, BAY1217389 abrogats nocodazole-induced SAC activity and induced premature exit from mitosis ("mitotic breakthrough"), resulting in multinuclearity and tumor cell death. It is found to inhibit cell proliferation with a median IC50 of 6.7 nmol/L (range 3 to >300 nmol/L)[1].
In vivo In vivo, BAY 1217389 achieves moderate efficacy in monotherapy in tumor xenograft studies. Its blood clearance is found to be low in the tested species. Vss is high and terminal half-lives were long. BAY 1217389 is administered orally to female NMRI mouse (1 mg/kg) and male Wistar rat (0.5 mg/kg). Peak plasma concentrations are observed between 1.5 and 7 hours. Oral bioavailability is high in rat and moderate in mouse[1].
Kinase Assay Inhibition of recombinant human Mps1 by BAY 1161909 or BAY 1217389 is assessed in TRFRET-based in vitro kinase assays via phosphorylation of a biotinylated peptide (Biotin-Ahx-PWDPDDADITEILG-NH2). Under standard assay conditions kinase and test compound are preincubated for 15 min before enzyme reaction is started by addition of substrate and ATP upon 10 μM[1].
Cell Research Cells are seeded into 96-well plates at densities ranging from 1,000 to 5,000 cells per well in the appropriate medium supplemented with 10% FCS. After 24 hours, cells are treated in quadruplicates with serial dilutions of compounds. After further 96 hours, adherent cells are fixed with glutaraldehyde and stained with crystal violet. IC50 values are calculated by means of a 4-parameter fit using the company's own software.(Only for Reference)

Molarity Calculator allows you to calculate the

  • Mass of a compound required to prepare a solution of known volume and concentration
  • Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Concentration of a solution resulting from a known mass of compound in a specific volume
See Example

An example of a molarity calculation using the molarity calculator
What is the mass of compound required to make a 10 mM stock solution in 10 ml of water given that the molecular weight of the compound is 197.13 g/mol?
Enter 197.13 into the Molecular Weight (MW) box
Enter 10 into the Concentration box and select the correct unit (millimolar)
Enter 10 into the Volume box and select the correct unit (milliliter)
Press calculate
The answer of 19.713 mg appears in the Mass box


Calculator the dilution required to prepare a stock solution

Calculate the dilution required to prepare a stock solution
The dilution calculator is a useful tool which allows you to calculate how to dilute a stock solution of known concentration. Enter C1, C2 & V2 to calculate V1.

See Example

An example of a dilution calculation using the Tocris dilution calculator
What volume of a given 10 mM stock solution is required to make 20ml of a 50 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=50 μM, V2=20 ml and V1 is the unknown:
Enter 10 into the Concentration (start) box and select the correct unit (millimolar)
Enter 50 into the Concentration (final) box and select the correct unit (micromolar)
Enter 20 into the Volume (final) box and select the correct unit (milliliter)
Press calculate
The answer of 100 microliter (0.1 ml) appears in the Volume (start) box

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed n the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
