title: Solid-phase synthesis of peptide vinyl sulfones as potential inhibitors and activity-based probes of cysteine proteases.
abstract: Peptide vinyl sulfones were prepared from 2-chlorotrityl resin-bound phenolic amino vinyl sulfones in high yield and purity. This method enables the convenient synthesis of peptide vinyl sulfones having different amino acids at the P(1) position. It also allows efficient synthesis of vinyl sulfone-containing, activity-based probes of cysteine proteases used in a proteomic experiment.
