PubMed Abstract:
E3 ubiquitin ligases, such as the therapeutically relevant VHL, are challenging targets for traditional medicinal chemistry, as their modulation requires targeting protein-protein interactions. We report novel small-molecule inhibitors of the interaction between VHL and its molecular target HIF1α, a transcription factor involved in oxygen sensing.
