PROTAC-mediated degradation of class I histone deacetylase enzymes in corepressor complexes

Chem Commun (Camb). 2020 Apr 21;56(32):4476-4479. doi: 10.1039/d0cc01485k.

Abstract

We have identified a proteolysis targeting chimera (PROTAC) of class I HDACs 1, 2 and 3. The most active degrader consists of a benzamide HDAC inhibitor, an alkyl linker, and the von Hippel-Lindau E3 ligand. Our PROTAC increased histone acetylation levels and compromised colon cancer HCT116 cell viability, establishing a degradation strategy as an alternative to class I HDAC inhibition.
