The first chemical inhibitor of the 19S regulatory particle (RP) of the proteasome is described. The molecule was identified by screening a library of nucleoside-capped peptoids for binding to the yeast 26S proteasome in a crude extract. The hit was resynthesized and shown to block 19S RP-mediated protein unfolding in vitro and proteasome-mediated turnover of p27 in HeLa cells.
