Biological Activity

Description BMH-21 is a DNA intercalator, which binds ribosomal DNA and inhibits RNA polymerase I (Pol I) transcription.
Targets
RNA polymerase I [1]
In vitro

BMH-21 causes proteasome-dependent destruction of RPA194, the large catalytic subunit protein of Pol I holocomplex. [1]

In U2OS cancer cell line, BMH-21 results in degradation of RPA194 and translocation of NCL with IC50 of 0.05 μM and 0.07 μM, respectively. By causing nucleolar stress, BMH-21 also shows potent inhibition on cell viability. [2]
In vivo

BMH-21 reduces tumor growth in mouse xenografts. [1]

Protocol (from reference)

Cell Assay:

[2]
  • Cell lines

    U2OS osteosarcoma cells

  • Concentrations

    ~5 μM

  • Incubation Time

    48 hours

  • Method

    The cells are maintained at 37 °C in a humidified atmosphere containing 5% CO2. U2OS osteosarcoma cells are cultured in DMEM supplemented with 15% fetal bovine serum. Cells are plated in 96-well plates at a density of 10000 cells/well in triplicate and incubated for 48 h with the compounds. Viability is determined using WST-1 cell proliferation reagent.
Animal Study:

[3]
  • Animal Models

    Athymic NCr nu/nu mice

  • Dosages

    25 or 50 mg/kg

  • Administration

    i.p.
