Biokatalysatoren für die Geranylierung von Peptiden mit Linearen und Zyklischen Prenylgruppen

Angewandte Chemie, EarlyView.
A combination of genome mining, synthetic biology, and biocatalytic assays revealed enzymes that install linear and cyclized prenyl moieties on ribosomally or chemically synthesized peptides. The promiscuity of both enzymes, while being specific for modification of C‐terminal tryptophans, enables enzymatic access to peptide terpenoid hybrids ...

Carbohydrate‐Directed Labeling Probes for UV‐Independent Chemoproteomic Profiling of Carbohydrate–Protein Interactions

Angewandte Chemie International Edition, Volume 65, Issue 44, 26 October 2026.
Modular carbohydrate‐directed labeling probes (CDLPs) convert weak carbohydrate–protein interactions into durable covalent tags in live cells without the need for multivalency or UV irradiation. Ligand binding triggers proximity‐enabled, glycan‐releasing acyl transfer to install a click handle for protein tagging and chemoproteomic profiling.

Aza‐Büchner–Curtius–Schlotterbeck Reaction Enables Selective Construction of Quaternary Carbon Centers

Angewandte Chemie International Edition, EarlyView.
We introduce the Aza‐Büchner–Curtius–Schlotterbeck (ABCS) reaction: A mild, catalyst‐free method for homologating aryl imines. Diverging from the traditional BCS mechanism, the diazo intermediate undergoes selective C─C insertion to form an all‐carbon quaternary center.

Activation of Metal Complexes With Ultrasound Waves for Targeted Anticancer Therapy

Angewandte Chemie International Edition, EarlyView.
Ultrasound enables non‐invasive activation of metal‐based therapeutics deep within tumors. Acoustic cavitation can drive sonodynamic reactive oxygen species generation or mechanochemical metal–ligand bond dissociation, enabling controlled release of bioactive payloads.

A Ruthenium(CAAC‐5) Olefin Metathesis Catalyst for Bioconjugation

Angewandte Chemie International Edition, EarlyView.
The aqueous instability of ruthenium catalysts restricts olefin metathesis in biological media. A Ru(CAAC‐5) complex bearing an aniline handle is reported that remains active under biologically relevant conditions and enables bioconjugation to proteins, peptides, and an artificial metalloenzyme, providing a robust platform for olefin metathesis in ...
