Molecular Engineering Boosts Photon‐Activated Immunotherapy for Prostate Cancer Through Concurrent Pyroptosis and cGAS‐STING Pathway Activation

Angewandte Chemie, EarlyView.
The engineered DTSe‐based photosensitizer, DZTSe, emerges as an avant‐garde molecular entity, which can distribute to both the endoplasmic reticulum and mitochondria to concurrently trigger pyroptosis and activate the cGAS‐STING pathway. This dual‐action strategy effectively reprograms the tumor microenvironment, enabling potent eradication of primary ...

Harnessing the Reactivity of Sulfinate Salts With Cystine: An Umpolung Approach to Residue‐Specific Peptide Modification

Angewandte Chemie, EarlyView.
While cysteine is widely employed as a nucleophilic handle for peptide modification, the electrophilicity of the oxidized form, cystine, is rarely exploited. This study describes a mild, photochemical coupling of sulfinate salts with peptide disulfides.

Kinetically Stable Boron‐Heteroatom Bonds

Angewandte Chemie, EarlyView.
This study investigates the kinetic stability of boron‐heteroatom bonds in N‐methyliminodiacetic acid (MIDA) boronates. The hemilabile nature of the ligand enables the synthesis of molecules that would otherwise be considered too hydrolytically labile. Depending on the structure, acid‐promoted migration of the boryl group was found to produce compounds

Excited‐State Antiaromaticity in Nonbenzenoid Aromatics: Examining the Dynamics of Intramolecular Proton Transfer With a Small Driving Force

Angewandte Chemie, EarlyView.
The excited‐state antiaromaticity of hydroxybenzotropyliums (HBTs) can be tuned through substituent effects to bring the aromatic ‘enol’ (E) and keto (K) tautomers close in energy. This leads to abnormally slow excited‐state proton transfer (on the ns timescale), giving rise to dual fluorescence emission and weak photoacidity.
