  • Fresh human PMP tissue was exposed to HIF-1α inhibitor (BAY 87-2243) under hypoxic conditions in vitro for 24 hours. MUC2 mRNA levels as measured by real-time PCR (F) and MUC2 protein expression as measured by immunofluorescence staining (G) were significantly reduced by the inhibitor; for immunofluorescence assay slides were stained with MUC2 antibody (green IF) and SYTOX Orange for nucleic acid (blue IF). Confocal images were randomly taken of 10 different fields (X 63 magnification) and analyzed using Image-pro Premier Software to quantify the average intensity of MUC2 expression.

  • Quiescent VSMC were pretreated with 10 or 30 μM HIF inhibitor BAY 87-2243 and then stimulated with PDGF (10 ng/mL) for 6 h. Total cell lysates were subjected to immunoblot analysis for HK2 and actin. Representative blots and compiled densitometric data from three independent experiments are depicted (n = 3, mean + SD.; * p b 0.05; ANOVA, Bonferroni).

Biological Activity

Description BAY 87-2243 is a potent and selective hypoxia-inducible factor-1 (HIF-1) inhibitor. Phase 1.
HIF-1 [1]
(Cell-free assay)
In vitro

BAY 87-2243 inhibits HIF-1 reporter gene activity and CA9 protein expression with IC50 of 0.7 nM and 2 nM, respectively. In hypoxic lung cancer H460 cells, BAY 87-2243 suppresses HIF target gene expression, and inhibits HIF-1α protein accumulation. Under glucose depletion, BAY 87-2243 inhibits cell proliferation via interference with mitochondrial function. [1]

Cell viability; 

PubMed: 26500770     

BRAF wild type and mutant melanoma cells were treated with various concentrations of BAY 87-2243. Cell viability was measured after 72 h. IC50 values were calculated using GraphPad prism (n = 4).

In vivo In H460 xenograft mouse model, BAY 87-2243 (4 mg/kg p.o.) reduces tumor weight, HIF-1α protein, and HIF-1 target gene expression levels. [1]


Cell Research:[1]

  • Cell lines: Non-small cell lung cancer (NSCLC) cell line H460
  • Concentrations: 10 μM
  • Incubation Time: 48 hours
  • Method: To evaluate the cytotoxicity of BAY 87-2243, 2.000 cells of the respective cell lines are seeded in 96-well plates and cultured in the appropriate growth medium containing 10% FCS. BAY 87-2243 at various concentrations is added at 24 h after seeding for additional 48 h and cell viability is determined using Cell Titer Glow Assay.

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 in 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.

Frequently Asked Questions

  • Question 1:

    How to formulate the compound for mouse in vivo experiment? I noticed that "For in vivo studies, BAY 87-2243 was formulated in a 1% (v/v) solution of ethanol/solutol/water (10/40/50%). Animals were given BAY 87-2243 (0.5, 1, 2, and 4 mg/kg) or vehicle control once daily by oral gavage" referred from Cancer Medicine 2013; 2(5): 611–624. What is solutol?

  • Answer:

    Solutol is a non-ionic solubilizer and emulsifier used in making vehicle formulations.
