Helical β-Peptide Inhibitors of the p53-hDM2 Interaction
Abstract
hDM2 is recognized in vivo by a short alpha-helix within the p53 trans-activation domain (p53AD). Disruption of the p53.hDM2 interaction is an important goal for cancer therapy. A functional epitope comprised of three residues on one face of the p53AD helix (F19, W23, and L26) contributes heavily to the binding free energy. We hypothesized that the p53AD functional epitope would be recapitulated if the side chains of F19, W23, and L26 were presented at successive positions three residues apart on a stabilized beta3-peptide 14-helix. Here, we report a set of beta3-peptides that possess significant 14-helix structure in water; one recognizes a cleft on the surface of hDM2 with nanomolar affinity. The strategy for beta3-peptide design that we describe is general and may have advantages over one in which individual or multiple beta-amino acid substitutions are introduced into a functional alpha-peptide, because it is based on homology at the level of secondary structure, not primary sequence.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
