In conclusion, we investigated the crystallographic signatures
of the self-assembled supramolecular helical architectures of
Boc-Gly-Phe-Phe-OMe (1) and Boc-Gly-Phg-Phe-OMe (2). SC-
XRD revealed that 1 formed a distorted type II β-turn confor-
mation, called the open turn, which further self-assembled
through intermolecular C–H⋯O bonding to form a herring-
bone helical architecture along the crystallographic c-axis.
Such open turn formation is unusual for a standard amino
acid containing the designed tripeptide without a kink-
forming element like proline or Aib. Alternatively, 2 exhibited
a β-sheet structure which further self-assembled through
intermolecular C–H⋯O and C–H⋯π bonding to form a heli-
cal architecture along the c-axis in the solid state. However,
in solution, both 1 and 2 exhibited a mixture of β-turn and
β-strand structures, supported by NMR and CD experiments.
Further, they self-associated to form two different flower-like
architectures in 30% acetonitrile–water medium. The differ-
ences in molecular and supramolecular level structural
arrangements of these two peptides are due to the presence
of the methylene group at the side chain of only one amino
acid (Phe), which is the only difference in their chemical
structures. This work may open up an avenue for the design
of open turn structures without using any pre-organized
kink inducing moieties. Formation of such a type of assembly
may be useful for designing nanostructures for nanotechnol-
ogy and materials chemistry. Furthermore, as 1 contain
C-terminal phenylalanylphenylalanine (–Phe-Phe–) residues,
identical with the core hydrophobic self-recognizing unit of
the amyloid-β peptide, such structural insight may be useful
for amyloid research.
