Peptoids constitute a class of peptidomimetics with potential as protease resistant, biologically active ligands. To harness the full potential of such compounds, however, detailed predictive insight into their propensity to adopt well-defined secondary structures is highly desirable. In this work we present an investigation of the effects of thioamides and/or fluorides in peptoid monomer model systems

Joining the fold: A series of peptoids, or oligomers of N‐substituted glycines, adopt a novel secondarystructure, designated the “peptoidribbon”. This fold was stable at short chain lengths and in a variety of solvents (both organic and aqueous), and arose from a primary sequence of peptoid monomers designed to enforce an alternating pattern of cis and trans main‐chain amides.
