Abstract: E3 ubiquitin ligases are attractive targets in the ubiquitin–proteasome system, however, the development of small-molecule ligands has been rewarded with limited success. The von Hippel–Lindau protein (pVHL) is the substrate recognition subunit of the VHL E3 ligase that targets HIF-1α for degradation. We recently reported inhibitors of the pVHL:HIF-1α interaction, however they exhibited moderate potency. Herein, we report the design and optimization, guided by X-ray crystal structures, of a ligand series with nanomolar binding affinities.
