Chemical macrocyclization of peptides fused to antibody Fc fragments

Christian Heinis, David Hacker, Laure Menin, Alessandro Angelini, Philippe Diderich, Julia Morales Sanfrutos, Sarah Thurnheer

To extend the plasma half-life of a bicyclic peptide antagonist, we chose to link it to the Fc fragment of the long-lived serum protein IgG1. Instead of chemically conjugating the entire bicyclic peptide, we recombinantly expressed its peptide moiety as a ...

Synthesis of glycopeptide dendrimers, dimerization and affinity for Concanavalin A

Ronan Euzen, Jean-Louis Reymond

We described herein the synthesis of second generation glycopeptide dendrimers G2a-g presenting variable amino acids placed internally into the multivalent scaffold. The effect of such structural modulation on recognition processes by Concanavalin A (Con A ...

Post-translational modification of genetically encoded polypeptide libraries

Christian Heinis, Alessandro Angelini

The genetic encoding of polypeptides with biological display systems enables the facile generation and screening of very large combinatorial libraries of molecules. By post-translationally modifying the encoded polypeptides, chemically and structurally mor ...

Benzothiazinones: prodrugs that covalently modify the decaprenylphosphoryl-β-D-ribose 2'-epimerase DprE1 of Mycobacterium tuberculosis

Stewart Cole, Kai Johnsson, Marlon Hinner, Claudia Trefzer, Monica Rengifo Gonzalez

Benzothiazinones (BTZs) form a new class of potent antimycobacterial agents. Although the target of BTZs has been identified as decaprenylphosphoryl-β-D-ribose 2'-epimerase (DprE1), their detailed mechanism of action remains obscure. Here we demonstrate th ...

Photoactivatable Probes for Protein Labeling

Sambashiva Banala

Over the last decade, several protein tags have been developed for the specific and covalent labeling of fusion proteins with small organic probes. Among them, SNAP-tag has been used in many applications such as live cell imaging, protein microarrays and t ...

Phage-encoded combinatorial chemical libraries based on bicyclic peptides

Christian Heinis

Here we describe a phage strategy for the selection of ligands based on bicyclic or linear peptides attached covalently to an organic core. We designed peptide repertoires with three reactive cysteine residues, each spaced apart by several random amino aci ...

Biomimetic PEG hydrogels crosslinked with minimal plasmin-sensitive tri-amino acid peptides

Matthias Lütolf, Jeffrey Alan Hubbell, Simone Rizzi, Martin Ehrbar

Semi-synthetic, proteolytically degradable polymer hydrogels have proven effective as scaffolds to augment bone and skin regeneration in animals. However, high costs due to expensive peptide building blocks pose a significant hurdle towards broad clinical ...

Probing Cysteine Reactivity in Proteins by Mass Spectrometric EC-Tagging

Hubert Girault, Christophe Roussel, Loïc Dayon

The on-line electrochemical tagging (EC-tagging) of cysteine residues in proteins during mass spectrometry is studied to probe the cysteine environment. Benzoquinone probes electrogenerated at a microspray electrode react with the thiol functions of the pr ...

Thiol-targeted microspray mass spectrometry of peptides and proteins through on-line EC-tagging

Loïc Dayon

Modification strategies targeting specific amino acids in proteins are widespread in proteomic analysis. Cysteine residues have received deep consideration in view of their nucleophilic properties and their occurrence in the proteome. A recently developed ...

On-Line Counting of Cysteine Residues in Peptides during Electrospray Ionization by Electrogenerated Tags and Their Application to Protein Identification

Hubert Girault, Niels Erik Lion, Christophe Roussel, Loïc Dayon, Michel Prudent

The electrochemically induced mass spectrometric tagging of cysteines by substituted hydroquinones was studied for peptides in a classical electrospray solvent (i.e., MeOH/H2O/AcOH 50/49/1). The tagging efficiency was tested with different hydroquinone com ...
