Proximity-enabled bioreactivity to generate covalent peptide inhibitors of p53-Mdm4

Chem Commun (Camb). 2016 Apr 14;52(29):5140-3. doi: 10.1039/c6cc01226d. Epub 2016 Mar 21.

Abstract

Although small molecule covalent inhibitors have been widely explored, macromolecular covalent inhibitors are more difficult to design and implement. Here we present a strategy to enable a peptide to bind to its target protein covalently via proximity-enabled bioreactivity, improving its activity of inhibiting the p53-Mdm4 interaction by 10-fold.
