Abstract

Unique ε-helical organizations (11-helices) from β,γ-hybrid peptides composed of chiral β3-amino acids along with achiral 3,3- or 4,4-dimethyl substituted γ-amino acids are disclosed.

Abstract

We are reporting the influence of foldamer structures on their self-assembled architectures. In a sharp contrast to the ordered α,γ-hybrid 12-helix obtained from 1 : 1 alternating Aib and γ-Phe, the α,γ-hybrid peptides constituted with α-Phe and 4,4-dimethyl γ-amino acid (Aic) displayed the extended sheet type of conformations in solution and spontaneously self-assembled into thermally and proteolytically stable capsules. In contrast, the conformationally ordered 12-helix self-assembled into a three-dimensional supramolecular polyhedron.
