Application
5,6-Dichlorobenzimidazole 1-β-D-ribofuranoside (DRB): A Selective Inhibitor of Transcription Elongation by RNA Polymerase II
5,6-Dichlorobenzimidazole 1-β-D-ribofuranoside (DRB) is a selective inhibitor of transcription elongation by RNA polymerase II, and then it inhibits of mRNA synthesis in eukaryotic cells. The inhibition can trigger p53-dependent apotosis of tumor cells. DRB can also inhibit HIV transcription by targeting elongation enhanced by the HIV-encoded transactivator (Tat).
