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 …

[HTML][HTML] Two-colour live-cell nanoscale imaging of intracellular targets

…, S Wood Baguley, G Sirinakis, A Schepartz… - Nature …, 2016 - nature.com
Stimulated emission depletion (STED) nanoscopy allows observations of subcellular
dynamics at the nanoscale. Applications have, however, been severely limited by the lack of a …

[HTML][HTML] The ecstasy and agony of assay interference compounds

…, D Liotta, KM Merz Jr, A Schepartz… - ACS Chemical …, 2017 - ACS Publications
The ecstasy of discovering a new hit from screening can lead to a highly productive research
effort to discover new bioactive compounds. However, in too many cases this ecstasy is …

Structure of the bacterial ribosome at 2 Å resolution

ZL Watson, FR Ward, R Méheust, O Ad, A Schepartz… - elife, 2020 - elifesciences.org
Using cryo-electron microscopy (cryo-EM), we determined the structure of the Escherichia coli
70S ribosome with a global resolution of 2.0 Å. The maps reveal unambiguous positioning …

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 …

Selective recognition of protein tetraserine motifs with a cell-permeable, pro-fluorescent bis-boronic acid

…, EM Hobert, DM Balkin, A Schepartz - Journal of the …, 2009 - ACS Publications
There is considerable interest in novel cell imaging tools that avoid the use of fluorescent
proteins. One widely used class of such reagents are “pro-fluorescent” biarsenical dyes such …

[PDF][PDF] Arginine topology controls escape of minimally cationic proteins from early endosomes to the cytoplasm

…, BA Smith, DM Balkin, JM Holub, A Schepartz - Chemistry & biology, 2012 - cell.com
Proteins represent an expanding class of therapeutics, but their actions are limited primarily
to extracellular targets because most peptidic molecules fail to enter cells. Here we identified …

Inhibiting HIV fusion with a β-peptide foldamer

…, ME Hodsdon, MS Kay, A Schepartz - Journal of the …, 2005 - ACS Publications
Linear peptides derived from the HIV gp41 C-terminus (C-peptides), such as the 36-residue
Fuzeon, are potent HIV fusion inhibitors. These molecules bind to the N-peptide region of …

Long time-lapse nanoscopy with spontaneously blinking membrane probes

…, JE Rothman, J Bewersdorf, A Schepartz… - Nature …, 2017 - nature.com
Imaging cellular structures and organelles in living cells by long time-lapse super-resolution
microscopy is challenging, as it requires dense labeling, bright and highly photostable dyes, …
