Lewis‐Acidic Properties and Catalytic Behavior of Hydroboration‐ and Diolysis‐Derived NHC‐Stabilized Borenium Cations

Chemistry – A European Journal, EarlyView.
A series of thirteen (N‐heterocyclic carbene) NHC‐stabilized borenium cations is synthesized from NHC→BH3 complexes via hydroboration and condensation with diols. The novel compounds are fully characterized. Eight crystal structures are presented. Kinetic and NMR data show how the structural features translate to catalytic activity in hydrosilylation ...

Diffusion of Carbamazepine in Hydrophobic Zeolites: A Comparative Study Using Classical and Machine‐Learned Potentials

Chemistry – A European Journal, EarlyView.
Can hydrophobic, shape‐selective zeolites efficiently remove the persistent pharmaceutical CBZ from water? This work moves beyond the static picture of interaction energies by modeling diffusion with umbrella sampling and machine‐learned potentials. Even high intrinsic diffusion barriers can be overcome through exergonic adsorption from water, yielding

Organelle‐Resolved Tetrazine‐trans‐Cyclooctene Click Chemistry for Cargo Delivery and Release

Chemistry – A European Journal, EarlyView.
Bioorthogonal click chemistry tools provide a means for specific intracellular conjugation of molecules. In this study, we used reactive tetrazine (Tz) and TCO moieties for labeling of organelles and organelle‐specific delivery and activation of doxorubicin prodrugs.

Peptide Marriages: Modular Assembly of Multi‐Agonist Therapeutics

Chemistry – A European Journal, EarlyView.
A modular polyethylene glycol (PEG) scaffold enables rapid assembly of dual peptide agonists using strain‐promoted azide–alkyne cycloaddition (SPAAC) and copper‐catalysed azide–alkyne cycloaddition (CuAAC). Glucagon‐like peptide‐1 (GLP‐1) and amylin agonists were combined with controlled valency, yielding low‐picomolar activity and receptor‐selective ...
