Scalable Azapeptide Macrocycles

Scalable Azapeptide Macrocycles

Lubell Lab

A convergent solution-phase strategy for a potent macrocyclic azapeptide CD36 modulator sidesteps preparative chromatography entirely, delivering 100 mg of >99%-pure material by swapping an oligomer-prone …

Activating Native Termini

Activating Native Termini

Raj Lab

Thiazoline and thiazole macrocycles embedded in bioactive marine peptides have long required pre-built specialty building blocks that slow synthesis and risk epimerization. A new palladium-mediated …

Bump-Gap Filaments

Bump-Gap Filaments

Chenoweth Lab

Natural collagen carries risks of immunogenicity and resists chemical modification, but synthetic collagen-mimetic peptides have struggled to match its continuous, mechanically robust fibrillar architecture. A …

Labeling Serine Selectively

Labeling Serine Selectively

Chen Lab

Serine and threonine hydroxyl groups are among the most difficult side chains to modify selectively in complex peptides, yet they govern phosphorylation, glycosylation, and enzyme …

Chaperone Orientation Rules

Chaperone Orientation Rules

Gierasch Lab

Three closely related Hsp70 molecular chaperones grip the same model peptides in strikingly different orientations: bacterial DnaK shows no directional preference, human Hsc70 leans toward …

Silencing Strep Signals

Silencing Strep Signals

Tal-Gan Lab

Streptococcus sinensis is an oral commensal that turns deadly when it reaches the bloodstream, causing infective endocarditis with roughly 25% mortality. A new mutational map …

Fragment Capping PDZ

Fragment Capping PDZ

Wilson Lab

β-strand-mediated protein–protein interactions are among the hardest targets in chemical biology, and PDZ domains are notoriously resistant to small-molecule ligands. A dynamic ligation screen against …

Stabilizing SNEW

Stabilizing SNEW

Sawyer Lab

The EphB2 receptor drives several cancers, yet its best peptide inhibitor, SNEW, has languished with modest potency and poor serum stability. Swapping its N-terminal serine …

Priming the Attack

Priming the Attack

Kimmel Lab

No peptide cancer vaccine has yet earned FDA approval, yet the field is converging on strategies that may finally close that gap. A new review …

Hunting Huntingtin

Hunting Huntingtin

Harding Lab

Huntingtin, the protein at the center of Huntington's disease, has long resisted selective chemical interrogation. A new suite of macrocyclic peptide tools now binds it …

Unlocking Small Macrocycles

Unlocking Small Macrocycles

VanVeller Lab

Short homochiral peptides routinely defeat macrocyclization attempts, either failing to close the ring or dissolving poorly enough to prevent even trying. A single backbone thioimidate …

Taming Bromine

Taming Bromine

Perrin Lab

For 35 years, the marine macrocycle orbiculamide A resisted total synthesis, largely because its 2-bromo-5-hydroxytryptophan residue defeats every conventional bromination strategy. Now, a chemoselective late-stage …

Mapping Hidden Enzymes

Mapping Hidden Enzymes

Wang Lab

Genome mining reliably maps biosynthetic gene clusters for ribosomally synthesized and post-translationally modified peptides, RiPPs, yet routinely misses enzymes encoded elsewhere in the genome. A …

Linkers Shape Collagen

Linkers Shape Collagen

Merg Lab

Covalently tethered collagen-mimetic peptides fold into triple helices and assemble into nanosheets, but how does the linker connecting each strand to its scaffold influence stability? …

Cornering RhoA G17V

Cornering RhoA G17V

Liu-Hampton Lab

RhoA G17V drives nearly 70% of angioimmunoblastic T-cell lymphoma cases yet has resisted every small-molecule effort for decades. Now, a phage-displayed macrocyclic peptide library yields …

Peptides on Demand

Peptides on Demand

Chatterjee Lab

Antibodies dominate biochemical research, but their context-dependent performance, reproducibility problems, and opaque binding determinants leave scientists wanting better tools. A new review from the Chatterjee …

Function-First Macrocycles

Function-First Macrocycles

Suga Lab

A new cell-based mRNA display platform bypasses affinity-only screening to discover a macrocyclic insulin receptor agonist that conventional methods would have missed...

Lighting Up Oligomers

Lighting Up Oligomers

Tonali Lab

A cyclopeptide-BODIPY conjugate built from Alzheimer's own amyloid sequence outperforms antibodies at spotting toxic prefibrillar aggregates inside neurons

Stabilizing Pseudouridimycin

Stabilizing Pseudouridimycin

Del Valle Group

Cryo-EM guided solid-phase synthesis yields 50 stabilized pseudouridimycin analogs, including a para-phenyl amidine that inhibits bacterial RNA polymerase fourfold better than the parent compound

Beyond the Membrane

Beyond the Membrane

Marcotte Lab

Researchers supervised by Professor Isabelle Marcotte at the Université du Québec à Montréal, published in J. Am. Chem. Soc., investigated three amphibian-derived AMPs with …

Activating Dehydroalanine

Activating Dehydroalanine

Liu and Wang Groups

A previously overlooked deprotonation of the dehydroalanine amide N–H unlocks selective arylation of peptides under mild conditions, with no metal catalyst required
