A fluorescent peptoid pH‐sensor
Peptide Science, 2013ABSTRACTPeptoids, N‐substituted glycine oligomers, can adopt stable three‐dimensional structures and have found diverse application as peptide surrogates and as nanomaterials. In this report, we have expanded peptoid function to include pH sensing by coupling pH‐induced peptoid conformational changes with fluorescence intensity changes.

Development of Spiroligomer–Peptoid Hybrids
The Journal of Organic Chemistry, 2017Creating functional macromolecules that possess the diversity and functionality of proteins poses an enormous challenge, as this requires large, preorganized macromolecules to facilitate interactions. Peptoids have been shown to interact with proteins, and combinatorial libraries of peptoids have been useful in discovering new ligands for protein ...

The search for novel, generally applicable and highly efficient delivery tools is a major activity in the biotechnology arena. Using highly optimized microwave based solid-phase chemistry a series of fluorescein-labelled cationic peptoid conjugates were synthesized within 24h and cellular uptake into HeLa, L929 and K562 cells examined via flow ...

Peptoid–Peptide Hybrid Backbone Architectures
ChemBioChem, 2010AbstractPeptidomimetic oligomers and foldamers have received considerable attention for over a decade, with β‐peptides and the so‐called peptoids (N‐alkylglycine oligomers) representing prominent examples of such architectures. Lately, hybrid or mixed backbones consisting of both α‐ and β‐amino acids (α/β‐peptides) have been investigated in some detail

Peptoid residues and beta-turn formation.
Journal of peptide science : an official publication of the European Peptide Society, 2002A set of terminally protected tripeptoids containing a residue of either N-methylglycine or N-isobutylglycine in position i + 1/i + 2 were synthesized and tested for intramolecularly H-bonded beta-turn formation. By exploiting FT-IR absorption and 1H NMR techniques, their folding tendencies were compared with those of a variety of reference peptides ...

Organic letters, 2008
The first synthesis of functionalized beta-peptoid macrocycles is reported. X-ray crystallographic structure of tetramer 9 reveals a C2-symmetrical derivative with unexpected all-cis-amide bonds and spatial disposition of the appendages toward the two opposite faces of the ring. Quantum calculations suggest that 9 is locked in this layout.
