Importance of dipole moments and ambient polarity for the conformation of Xaa–Pro moieties – a combined experimental and theoretical study

The trans : cis isomer ratio of Xaa–Pro bonds is significantly affected by the polarity of the environment. Computational and NMR spectroscopic studies revealed an intricate balance between polarity effects and interactions of carbonyl groups.

Bridged bicyclic peptides as potential drug scaffolds: synthesis, structure, protein binding and stability

Diastereomeric norbornapeptides represent globular scaffolds with geometries determined by the chirality of amino acid residues and sharing structural features of β-turns and α-helices.

Spontaneous head-to-tail cyclization of unprotected linear peptides with the KAHA ligation

The α-ketoacid–hydroxylamine (KAHA) ligation enables the direct cyclization of unprotected peptides upon cleavage, without coupling reagents or purification of precursors. We report the synthesis of a library of 24 cyclic peptides and a detailed mechanistic study.

Harnessing selenocysteine reactivity for oxidative protein folding

Turbo-charged folding with selenium: targeted replacement of cysteines in proteins with selenocysteines is a valuable strategy for increasing the rates of oxidative protein folding, altering folding mechanisms, and rescuing kinetically trapped intermediates.

About this collection

We are delighted to present this web collection which contains selected contributions from the ISACS16: Challenges in Chemical Biology held in Zurich, Switzerland in June 2015. Delegates from ~25 countries around the world gathered to hear from leading researchers in this exciting field and now we have the opportunity to share with you exciting new research from a number of our plenary speakers and scientific committee members. All the articles are fully Open Access so anyone can read them. We hope you enjoy the collection.
