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.
本文描述了蛋白酶体19S调节颗粒（RP）的首个化学抑制剂。该分子是通过筛选核苷封端的类肽文库，以寻找能与粗提物中的酵母26S蛋白酶体结合的物质而鉴定出来的。对筛选出的活性物质进行了重新合成，并证明其在体外可阻断19S RP介导的蛋白质解折叠，在HeLa细胞中可阻断蛋白酶体介导的p27周转。
