Description: 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.
