Chemoenzymatic Synthesis of Well‐Defined α(2,8)‐ and α(2,9)‐Linked Oligosialosides

Angewandte Chemie, EarlyView.
Well‐defined α(2,8)‐ and α(2,9)‐linked oligosialic acids of different lengths can be prepared by employing recombinant bacterial polysialyltransferases in combination with chemically modified CMP‐Neu5Ac derivatives. After transfer, a sialoside is formed bearing an artificial entity, which blocks further glycosylation.

Discovery of a Reversible Sub‐Picomolar Thrombin Inhibitor Using DCC

Angewandte Chemie, EarlyView.
An ultrapotent yet fully reversible trivalent thrombin inhibitor discovered through screening a large dynamic combinatorial library (DCL) of 125 000 members of self‐assembled fragments. The innovative approach leverages size‐exclusion‐based affinity selection, coupled with MALDI‐TOF mass spectrometry readout, enabling the full workflow to be completed ...

Redirecting Excited‐State Proton Transfer Through Supramolecular Polymerization in Nanoconfinement

Angewandte Chemie, EarlyView.
Supramolecular confinement redirects the excited‐state proton transfer pathway of an amphoteric emitter. In water, the molecule undergoes ESPD, whereas co‐assembly with γ‐cyclodextrin forms nanotubes that template slip‐stacked emitter pairs and enable ESIMPT. Structural and photophysical characterization of the assemblies shows that the preorganization

Light and Dark Cycles Control the Structural Evolution of Photoresponsive Supramolecular Systems

Angewandte Chemie, EarlyView.
Here, we report a photoswitchable synthetic peptide that, under light energy cycles, exhibits supramolecular polymorphism coupled to darkness‐driven structural self‐selection. We demonstrate that light sustains a transient assembled state in the form of helical nanoribbons, hindering the system from undergoing a transition to the disassembled state ...

An Enzymatic Platform for Late‐Stage (Radio)isotope Labelling of Oligonucleotides With Methyltransferases

Angewandte Chemie, EarlyView.
State‐of‐the‐art synthesis of radiolabelled oligonucleotides involves multi‐step synthesis with high costs, extended timelines and significant radioactive waste generation. Herein, a dual‐methyltransferase platform enables late‐stage, site‐specific labelling, overcoming these limitations through reduced costs, faster turnaround and minimal radioactive ...
