Oligomers of a new class of sugar amino acids (SAA) using a xylofuranoic acid has been shown to generate a robust 14-helix. The design involved the use of xylofuranose with a cis arrangement between the amine and carboxyl groups to promote the adoption of a 14-helix instead of a mixed 12/10-helix observed in a sugar oligomer using a ribofuranoic acid and β-Ala. The observation of a stable right-handed 14-helix in a cis-SAA is unprecedented. Copyright

The conformational control of a 14-helix nucleating template, cis-β-furanoid sugar amino acid (FSAA), over a flexible δ-amino acid, ornithine is studied in a FSAA-ornithine cyclic tetrapeptide. Extensive NMR and MD studies reveal that the cyclic peptide adopts a three-dimentional bowl-shape cavity, which promotes six- and seven-membered intra- and inter-residue H-bonding, in polar and nonpolar solvents, respectively.
