Biological Activity

Description BAY-1816032 is a potent and oral available inhibitor of budding uninhibited by benzimidazoles 1 (BUB1) kinase with IC50 of 6.1 nM for recombinant catalytic domain of human BUB1. BAY-1816032 has antitumor activity.
Targets
BUB1 [1]
(Cell-free assay)
6.1 nM
In vitro

BAY 1816032 is a novel, bioavailable inhibitor of the catalytical activity of the mitotic checkpoint protein BUB1, which is involved in centromere cohesion and attachment error correction. Inhibition of BUB1 sensitizes tumor cells towards paclitaxel and docetaxel, and towards ATR inhibitors and PARP inhibitiors.[1]

In vivo

In xenograft models of triple-negative breast cancer BAY 1816032 in combination with paclitaxel or olaparib strongly delays outgrowth of tumors under treatment as compared to paclitaxel or olaparib single agents.[1]

Protocol (from reference)

Cell Research:

[1]

  • Cell lines: HeLa, SUM-149, MDA-MB-436, NCI-H1299, 22RV1, H4 cells.
  • Concentrations: 0.1 μM to 10 μM
  • Incubation Time: 4 h, 24 h, 48 h, 72 h, 96 h
  • Method:

    Cells are plated into 384-well plates at densities between 600 and 800 cells per well. After 24 h, cells are treated with BAY 1816032 and the second compound either as single compound treatments, or in nine fixed compound ratios. Cell viability is assessed after 96 hour exposure, using the CellTiter-Glo Luminescent Cell Viability Assay.

Animal Research:

[1]

  • Animal Models: male Wistar rats, female CD1 mice, female Beagle dog
  • Dosages: 1.0 mg/kg, 0.5 mg/kg, 5 mg/kg, 10 mg/kg, 25 mg/kg, 40 mg/kg, 50 mg/kg, 100 mg/kg
  • Administration: Oral gavage, IV

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid 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 master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
