Abstract

Backbone modification by conformational restriction of amide bond is an attractive strategy to obtain useful information about bioactive conformation of peptides [1, 2]. Such modifications introduce local backbone constraints, eg N-α-alkylation greatly limits the φ torsional angle that restricts the affected residue and the amino acid preceding it to an extended conformation [3], eliminates the potential intramolecular hydrogen bonding ...
