The present invention relates to a method for preparing a peptide having a stable, internally constrained alpha-helical, beta-sheet/beta-turn, 310-helical, or pi-helical region and a method of stabilizing an alpha-helical, beta-sheet/beta-turn, 310-helical, or pi-helical region within a peptide structure. The resulting peptides and methods of using them are also disclosed.

Amino acid derived 2-nitrobenzenesulfonamides were successfully condensed under Mitsunobu conditions with the primary alcohol of various saccharide and nucleoside derivatives to furnish the fully protected hybrids in excellent yield. One such hybrid was incorporated into a short peptide sequence in good overall yield. (C) 2001 Elsevier Science Ltd. All rights reserved.

Herein we describe a strategy for the preparation of artificial alpha-helices involving replacement of one of the main-chain hydrogen bonds with a covalent linkage. To mimic the C=O...H-N hydrogen bond as closely as possible, we envisioned a covalent bond of the type C=X-Y-N, where X and Y are two carbon atoms connected through an olefin metathesis reaction. Our results demonstrate that the replacement of a hydrogen bond between the i and i + 4 residues at the N-terminus of a short peptide with a carbon-carbon bond results in a highly stable constrained alpha-helix at physiological conditions as indicated by CD and NMR spectroscopies. The advantage of this strategy is that it allows access to short alpha-helices with strict preservation of molecular recognition surfaces required for biomolecular interactions.
