Design, synthesis, and crystal structure of self-assembling norbornene (NBE)-supported two-helix bundles: a unique example of Janus helicity in the solid-state structure of NBE(Aib(5))(2)

Conformation-specific spectroscopy of capped, gas-phase Aib oligomers: tests of the Aib residue as a 310-helix former

Single-conformation spectroscopy is used to probe the preference for helical structural in Aib-homopeptides.

Super-secondary structure peptidomimetics: design and synthesis of an α-α hairpin analogue

The α-α helix motif presents key recognition domains in protein-protein and protein-oligonucleotide binding, and is one of the most common super-secondary structures. Herein we describe the design, synthesis and structural characterization of an α-α hairpin analogue based on a tetra-coordinated Pd(II) bis-(iminoisoquinoline) complex as a template for the display of two α-helix mimics. This approach is exemplified by the attachment of two biphenyl peptidomimetics to reproduce the side-chains of the i and i+4 residues of two helices.
