Novel Organic Proteasome Inhibitors Identified by Virtual and in Vitro Screening

Abstract excerpt

Proteasome inhibition is a promising strategy for treating cancers. Herein, we report the discovery of novel drug-like inhibitors of mammalian proteasome 20S using a multistep structure-based virtual ligand screening strategy. Sulfone- or piperazine-containing hits essentially belong to the under-represented class of noncovalent and nonpeptidic proteasome inhibitors. Several of our compounds act in the micromolar...
