Figure 1. (a) Chemical structure of TMC-95s including diastereomers A to D. (b) The lead structure segment of TMC-95s which contributes the most to proteasome inhibition. The S1 and S3 residues, shown in blue, mark specific amino acid residues that are major determinants for differential binding to proteasomal subunits.
