Integrierte chemo‐enzymatische Synthese des mRNA‐Impfstoff‐Bausteins N1‐Methylpseudouridintriphosphat

Angewandte Chemie, EarlyView.
Pseudouridin‐5'‐triphosphat (ΨTP) und sein N1‐methyliertes Derivat (m1ΨTP) sind entscheidende Komponenten in der mRNA‐Impfstofftechnologie. Hier wird ein atomökonomischer, ertragreicher biokatalytischer Weg zur Synthese von ΨTP vorgestellt. Zudem wurde ein neuer chemo‐enzymatischer Weg für die m1ΨTP‐Synthese entwickelt.

Building a Bridge Between Ambient MS and LC‐MS by Non‐Exhaustive Microdesorption

Angewandte Chemie International Edition, Accepted Article.
Ambient mass spectrometry (AMS) offers rapid screening but faces challenges in analyzing complex samples due to high matrix effects and limited selectivity. The absence of a separation step can also lead to false positives due to the isomers or isobars.

Integrated Chemoenzymatic Synthesis of the mRNA Vaccine Building Block N1‐Methylpseudouridine Triphosphate

Angewandte Chemie International Edition, EarlyView.
Pseudouridine‐5′‐triphosphate (ΨTP) and its N1‐methylated derivative (m1ΨTP) are crucial components in mRNA vaccine technology. Here, an atom‐economic, high‐yielding biocatalytic route for ΨTP synthesis is presented. A new chemoenzymatic route for m1ΨTP synthesis was developed.

A Multistate Adaptive System of Topologically Distinct Chiral Assemblies

Angewandte Chemie International Edition, Accepted Article.
Biological systems exemplify the extraordinary adaptability of living organisms to their surroundings, demonstrating the capacity to reconfigure their structure, properties, and function in response to specific environmental signals. In this context, the exploration of multistate chemical systems designed to mimic natural counterparts, with the ...

Multisite Proton‐Coupled Electron Transfer Facilitates Oxidative Photocatalysis in a Molecular Zr‐Based Coordination Compound

Angewandte Chemie International Edition, Accepted Article.
The development of mediators that harness visible light to drive proton‐coupled electron transfer (PCET) offers a promising pathway to achieving challenging redox transformations in a more sustainable manner and with enhanced thermochemical efficiency.
