New β-Strand Templates Constrained by Huisgen Cycloaddition
摘要:
New peptidic templates constrained into a beta-strand geometry by linking acetylene and azide containing P-1 and P-3 residues of a tripeptide by Huisgen cycloaddition are presented. The conformations of the macrocycles are defined by NMR studies and those that best define a beta-strand are shown to be potent inhibitors of the protease calpain. The beta-strand templates presented and defined here are prepared under optimized conditions that should be suitable for targeting a range of proteases and other applications requiring such a geometry.

Peptide‐derived proteaseinhibitors are an important class of compounds with the potential to treat a wide range of diseases. Herein, we describe the synthesis of a series of triazole‐containing macrocyclic proteaseinhibitors pre‐organized into a β‐strand conformation and an evaluation of their activity against a panel of proteases. Acyclic azido–alkyne‐based aldehydes are also evaluated for comparison
