A small-molecule VHL molecular glue degrader for cysteine dioxygenase 1 - Nature Chemical Biology High-content protein arrays were used to identify cysteine dioxygenase (CDO1) as a small-molecule glue target for the von Hippel–Lindau (VHL) E3 ubiquitin ligase and induces VHL-dependent proteasomal ...

Excited to see this work in @natchembio.nature.com from our Novartis teams. They report the discovery of a small molecule that binds pVHL, functioning as a molecular glue degrader. The findings suggest new opportunities to leverage VHL molecular glues.
