General description

A cell-permeable indazolo-sulfonamide compound that displays broad-spectrum inhibitory activity against RNA Polymerase III (IC50 = 27 and 32 µM for human and S. cerevisiae RNA Pol III, respectively). Inhibits cell growth in yeast by preventing RNA Pol III-mediated tRNA transcription. Also available as a 25 mM solution in DMSO (Cat. No. 557404).

More than 98% of the human genome is comprised of non-protein coding sequences. Interestingly, a considerable fraction of these sequences is transcribed into non-protein coding RNA transcripts. These transcripts range in size from very small RNAs such as the miRNAs
