A novel approach to the α-mercaptodiketopiperazine nucleus is reported, which involved a three-component reaction of a number of amines with ethyl glyoxalate and para-methoxybenzylmercaptan. The subsequent products were readily elaborated to the monothiodiketopiperazine core structure.

substratein vitro. Further characterization revealed that ETPs inhibited proteasome function by targeting the essential proteasomal deubiquitinase Rpn11 (POH1/PSMD14). ETPs also inhibited other JAMM (JAB1/MPN/Mov34 metalloenzyme) proteases such as Csn5 and AMSH. An improved ETP with fewer non-specific effects, SOP11, stabilized a subset of proteasome substrates in cells, induced the unfolded protein response, and
