In vitro

BAY-1895344 inhibits tumor cell growth and viability and exhibits potent antiproliferative activity in a broad spectrum of human tumor cell lines.[2]

In vivo

BAY 1895344 exhibits strong monotherapy efficacy in cancer xenograft models that carry DNA damage repair deficiencies.[2]

Protocol (from reference)

Cell Research:

[2]

  • Cell lines: HT-29 cells, M059J cells, 38 cancer cell lines
  • Concentrations: 3–300 nM
  • Incubation Time: 72 to 96 hours
  • Method:

    The antiproliferative activity of BAY 1895344 is evaluated against a panel of 38 cancer cell lines. Cell proliferation is measured after 72 to 96 hours of exposure to BAY1895344. Cell viability is determined using crystal violet staining or the CellTiter-Glo Cell Viability Assay.

Animal Research:

[2]

  • Animal Models: female SCID beige mice, female C.B-17 SCID mice, male NMRI nude mice, female NMRI nude mice
  • Dosages: 50 mg/kg
  • Administration: Oral gavage

Calculation results:

Working concentration: mg/ml;

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.
