Peptide Thioester and Triazole Derivatives Through On‐Resin Dual‐Modification of Peptide Thiosulfonates

Angewandte Chemie International Edition, EarlyView.
An on‐resin dual‐modification strategy for peptides is presented, comprising S‐alkynylation of peptide thiosulfonates and regioselective iridium‐catalyzed azide–thioalkyne cycloaddition. This method reliably provides access to peptides with intricate non‐canonical modifications, being compatible with complex peptides, alkynes and azides.

Circular Photocaged mRNA for Light‐induced Late‐stage Activation of Translation

Angewandte Chemie International Edition, EarlyView.
A clickable photo‐caged 5′ cap (CyCliCap) allows to make Cyclic Click Cap‐containing mRNA (CyCliCap‐mRNA) which is remarkably stable and translationally muted until irradiated, allowing for late‐stage activation of translation in cells by light. ABSTRACT mRNA is a new medical modality as vaccine and raises hopes to become a protein replacement agent ...
