Furanoid sugar amino acid based peptidomimetics: well-defined solution conformations to gel-like structures

Furanoid sugar amino acid based peptide and a dimer fold into pseudo β-turn-like structures in DMSO-d6 with intramolecular H-bonds between LeuNH and sugarOH. In CDCl3, they display a repeating β-turn-type secondary structure at lower concentrations and start to form aggregates that gradually turn into excellent organogels as the concentrations are increased, a phenomenon observed for the first time in sugar amino acid containing peptides.
