BMH 21

BMH-21 is a small molecule DNA intercalator that binds ribosomal DNA and inhibits RNA polymerase I (Pol I) transcription; does not cause phosphorylation of H2AX.IC50 value: 10-90 nM(RPA195 IC50) [1]Target: RNA Pol I inhibitorin vitro: 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 [1].
