Foldamers Fight Resistance

Foldamers Fight Resistance

Cai Lab

Natural antimicrobial peptides promise a way around drug resistance, but proteolytic instability and cytotoxicity have blocked their clinical path. A new class of right-handed D-sulfonyl-γ-AApeptide …

Editing Serine's Silence

Editing Serine's Silence

Li Lab

Serine and threonine dominate regulatory post-translational modifications in biology, yet chemical tools to edit them site-selectively in unprotected peptides have remained out of reach. A …

Shielding Thioacetals

Shielding Thioacetals

Li Lab

Aggregation-prone proteins have long defeated chemical synthesis because the protecting groups needed to suppress aggregation could not survive the acid deprotection step. A picolinoylation strategy …

Radical Ring Fusion

Radical Ring Fusion

Dong Lab

Lanthipeptides have never been found to carry an azepinoindole scaffold, and radical SAM enzymes have never been caught stitching together two adjacent residues in a …

Greening Peptide Math

Greening Peptide Math

Albericio and De La Torre Lab

Peptide APIs carry some of the highest process mass intensity values in pharmaceuticals, yet most labs still skip the calculation entirely because the mass accounting …

Untangling Interlocked Peptides

Untangling Interlocked Peptides

Link Lab

Mechanically interlocked peptides span lasso peptides, cysteine knots, and viral chainmail capsids, yet the fields studying them have run in parallel rather than together. A …

Siderophore Shape-Shifting

Siderophore Shape-Shifting

Hertweck Lab

Bacteria rarely repurpose a single metabolite to serve two opposing ecological needs, yet that is precisely what Pandoraea species do with their pandorachelin lipopeptides: an …

Nucleolar Droplets On Demand

Nucleolar Droplets On Demand

Department of Synthesis of Macromolecules at the Max Planck Institute for Polymer Research

Synthetic coacervates that form inside living cells and then dissolve on command would open a new class of reversible compartments, but reaching the concentrations needed …

Tuning Integrin Selectivity

Tuning Integrin Selectivity

Wang and Hu Lab

RGD peptides have long struggled to distinguish between closely related integrin subtypes, limiting their diagnostic precision. A new conformational tuning strategy, varying cross-linker length and …

Mining Biarylitides

Mining Biarylitides

Crüsemann and Cryle Groups

Biarylitides are bacterial RiPPs built from the smallest known genes in all of life, just 18 base pairs, making them nearly invisible to conventional genome …

Aldehyde Backbone Bending

Aldehyde Backbone Bending

Suga Lab

α-Amino-γ-lactam residues impose backbone constraints that can boost membrane permeability, yet no method existed for installing them post-translationally inside a display system. Now, an aldehyde-triggered …

Stapling With PMDA

Stapling With PMDA

Zhang and Li Groups

Peptide stapling typically demands exotic amino acids, cysteine handles, or metal catalysts, each carrying trade-offs in selectivity or modularity. A new pyromellitic dianhydride linker sidesteps …

Editing Lysine Radically

Editing Lysine Radically

Arora Lab

Lysine's aliphatic C–H bonds have long resisted selective functionalization, leaving a rich vein of branched unnatural amino acid motifs out of reach. A photoredox strategy …

Decoding HDAC Inhibitor Assembly

Decoding HDAC Inhibitor Assembly

Challis & Alkhalaf Labs

A family of depsipeptide HDAC inhibitors that includes the lymphoma drug romidepsin share a conserved pharmacophore fused to structurally diverse peptide caps, but the molecular …

Pores by Design

Pores by Design

Vácha Lab

Antibiotic-resistant bacteria are running out of places to hide. Researchers have now built a computational pipeline that designs synthetic peptides from scratch to punch stable, …

Angles Govern Assembly

Angles Govern Assembly

Ghosh Lab

Adding a single methylene spacer between a pyrene chromophore and a tetrapeptide backbone shifts the molecular angle from 128° to 68°, flipping the π-stacking mode …

Protein Space Illuminated

Protein Space Illuminated

DeGrado Lab

How often does a random sequence fold into a stable protein? Surprisingly often, if that sequence repeats itself. A large-scale computational survey of tandem-repeat proteins …

Foldamers in Membranes

Foldamers in Membranes

Clayden Lab

Synthetic foldamers that switch their internal hydrogen-bond direction could one day carry signals across cell membranes, but only if their conformational dynamics survive the lipid …

Groovy Foldamer Design

Groovy Foldamer Design

Huc Lab

Aromatic foldamers that mimic DNA can already outcompete the double helix for binding certain proteins, but their repetitive structure limits sequence-specific recognition. Now, four new …

Rethinking GPA Recognition

Rethinking GPA Recognition

Davis Lab

Glycopeptide antibiotics are thought to work by gripping a single peptidoglycan motif through five hydrogen bonds. But when researchers simulated a recently discovered antibiotic that …

Mushroom Toxins Decoded

Mushroom Toxins Decoded

Süssmuth Lab

Cortinarins are bicyclic peptides from toxic Cortinarius mushrooms that have resisted independent biological study for decades. A new total synthesis now unlocks milligram quantities of …

Bismuth Cyclisation Inside Living Cells

Bismuth Cyclisation Inside Living Cells

Jody Mason Lab

Cyclisation is one of the most dependable ways to make a peptide behave more like a drug, tightening its fold, sharpening target engagement, and slowing …

Tricycles from Display

Tricycles from Display

Jongkees Lab

Tricyclic peptides offer tighter binding, better selectivity, and longer serum lifetimes than simpler macrocycles, but generating single regioisomers at the high dilution of mRNA display …

Questioning Cation–π

Questioning Cation–π

Gellman Lab

A long-held hypothesis holds that cation–π interactions between arginine and tyrosine side chains drive protein condensate formation. A new two-component model system built from a …
