Helical β-peptide inhibitors of the p53-hDM2 interaction
…, JD Lear, ME Hodsdon, A Schepartz - Journal of the American …, 2004 - ACS Publications
hDM2 is recognized in vivo by a short α-helix within the p53 trans-activation domain (p53AD).
Disruption of the p53·hDM2 interaction is an important goal for cancer therapy. A functional …

High-resolution structure of a β-peptide bundle
…, EJ Petersson, JX Qiu, A Schepartz - Journal of the American …, 2007 - ACS Publications
We recently reported that β-peptides can form discrete hetero-oligomers in aqueous solution.
Here we describe the structure of such an oligomer as determined by X-ray crystallography…

β-Peptides as inhibitors of protein–protein interactions
…, DA Guarracino, SK Reznik, A Schepartz - Bioorganic & medicinal …, 2005 - Elsevier
We became interested several years ago in exploring whether 14-helical β-peptide foldamers
could bind protein surfaces and inhibit protein–protein interactions, and if so, whether their …
