Angewandte Chemie International Edition, EarlyView.An orthogonal click chemistry approach was used to synthesize a series of cationic surfactants. The results show that an optimal balance between positive charges and hydrophobicity is a crucial factor for the improvement of antibacterial properties.

Angewandte Chemie International Edition, EarlyView.Generating functionalized ubiquitin building blocks via expression in E. coli paves the way to different di‐, tri‐, and tetra‐ubiquitin chains. Light‐induced thiol‐ene click reactions, combined with a masking and protection strategy, are harnessed to establish controlled ubiquitin chain assembly and to allow the semisynthesis of site‐selectively ...
