Product Information

BMH-21 is a potent small molecule DNA intercalator. BMH-21 binds ribosomal DNA and inhibits RNA polymerase I (Pol I) transcription. BMH-21 does not cause phosphorylation of H2AX, a key biomarker activated in DNA damage stress. BMH-21 effects on the nucleolar stress response were independent of major DNA damage associated PI3-kinase pathways, ATM, ATR and DNA-PKcs. BMH-21 is a chemically unique DNA intercalator that has high bioactivity towards Pol I inhibition without activation or dependence of DNA damage stress. The findings also show that interference with DNA and DNA metabolic processes can be exploited therapeutically without causing DNA damage.

In Vitro

BMH-21 binds ribosomal DNA and inhibits RNA polymerase I (Pol I) transcription.

BMH-21 inhibits RNA polymerase I independent of DNA damage response.

BMH-21 inhibits transcription of RNA polymerase I (Pol I) by binding to ribosomal (r) DNA that caused Pol I blockade and degradation of the large catalytic subunit of Pol I, RPA194.

BMH-21 intercalates into double strand (ds) DNA and has binding preference towards GC-rich DNA sequences.

BMH-21 (1 μM; 3 h ours) acts in a DNA damage independent manner to activate nucleolar stress and RPA194 degradation.

 

In Vivo

BMH-21 (50 mg/kg; i.p.; daily, for 6 days) inhibits HCT116 colon cancer tumor growth in vivo.
