  Synthesis and Characterization of trans-2-Aminocyclohexanecarboxylic Acid Oligomers:  An Unnatural Helical Secondary Structure and Implications for β-Peptide Tertiary Structure

  摘要：

  The preperation, crystal structures, and circular dichroism(CD)spectra of two oligomers of optically active trans-2-aminocyclohexanecarboxylic acid are reported. In the solid state, both the tetramer and the hexamer of this beta-amino acid display a helical conformation that involves 14-membered-ring hydrogen bonds between a carbonyl oxygen and the amide proton of the second residue toward the N-terminus. (For comparison, the familiar cc-helix observed in conventional peptides is associated with a 13-membered-ring hydrogen, bond between a carbonyl oxygen and the amide proton of the fourth residue toward the C-terminus.) These. :crystallographic data, along with CD data obtained in methanol, suggest that the 14-helix constitutes a stable secondary structure for beta-amino acid oligomers ("beta-peptides"). In addition, the cryst al packing pattern observed for the hexamer offers a blueprint for the design of beta-peptides that might adopt a helical bundle tertiary structure.

  Disclosed are isolated, unnatural polypeptides containing cyclically-constrained β-amino acid residues and cyclically-constrained γ-amino acid residues. The compounds are unnatural and because they contain rotationally constrained residues that are not amenable to enzymatic degradation, the compounds are useful to probe protein-protein and other large molecule interactions.

  本发明涉及一种孤立的、非天然的多肽，其中包含有环限制的β-氨基酸残基和环限制的γ-氨基酸残基。这些化合物是非天然的，因为它们包含有旋转限制的残基，不易于酶降解，因此这些化合物可用于探究蛋白质-蛋白质和其他大分子相互作用。
