5,6-Dichloro-1-beta-D-ribofuranosylbenzimidazole


5,6-Dichloro-1-β--ribofuranosylbenzimidazole is a chemical compound that inhibits transcription elongation by RNA Polymerase II. Sensitivity to DRB is dependent on DRB sensitivity inducing factor, negative elongation factor, and positive transcription elongation factor b. DRB is a nucleoside analog and also inhibits some protein kinases.
