Oxygels: Tunable Phosphorescent Hydrogels for Cherenkov‐Excited Luminescence Imaging (CELI) of Oxygen

Advanced Healthcare Materials, EarlyView.
Biocompatible hydrogels with covalently embedded near‐infrared phosphorescent probes enable local tissue pO2 quantification by means of Cherenkov‐excited luminescence imaging (CELI), where optical excitation occurs within tissues upon irradiation with high‐energy electron beams.

A Fragment-Based Method to Discover Irreversible Covalent Inhibitors of Cysteine Proteases

Journal of Medicinal Chemistry, 2014
A novel fragment-based drug discovery approach is reported which irreversibly tethers drug-like fragments to catalytic cysteines. We attached an electrophile to 100 fragments without significant alterations in the reactivity of the electrophile. A mass spectrometry assay discovered three nonpeptidic inhibitors of the cysteine protease papain.

Mode of action of a DCAF16-recruiting targeted glue that can selectively degrade BRD9

Nature Communications
Molecular glue degraders for therapeutic target proteins are emerging as a strategy in drug discovery. Here, we modify a BRD9 ligand with specific chemical fragments to create degrader compounds that we call Targeted Glues.
