Description

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).
