Phage Display Selection against a Mixture of Protein Targets

Affinity selections by phage display or other display techniques are typically performed against single targets immobilized as a purified protein. In order to develop cross-specific binders that engage with multiple proteins, such as members of a related f ...

Towards the Development of Orally Available Peptide Therapeutics

Christian Heinis, Xudong Kong

Peptides have a number of attractive properties that make them an interesting modality for drug development, including their ability to bind challenging targets, their high target specificity, and their non-toxic metabolic products. However, a major limita ...

Generation of a 100-billion cyclic peptide phage display library having a high skeletal diversity

Christian Heinis, Xudong Kong, Vanessa Carle, Alice Comberlato, Cristina Diaz Perlas

Phage display is a powerful technique routinely used for the generation of peptide- or protein-based ligands. The success of phage display selections critically depends on the size and structural diversity of the libraries, but the generation of large libr ...

A minimalistic cyclic ice-binding peptide from phage display

Harm-Anton Klok, Matthew Gibson, Luciano Andres Abriata, Xudong Kong, Corey Alfred Stevens

Developing molecules that emulate the properties of naturally occurring ice-binding proteins (IBPs) is a daunting challenge. Rather than relying on the (limited) existing structure–property relationships that have been established for IBPs, here we report ...

Development of Selective FXIa Inhibitors Based on Cyclic Peptides and Their Application for Safe Anticoagulation

Christian Heinis, Camille Villequey, Xudong Kong, Kaycie Marie Butler, Vanessa Carle, Christina Lamers, Tamara Maric, Chloé Rogg, Cristina Diaz Perlas

Coagulation factor XI (FXI) has emerged as a promising target for the development of safer anticoagulation drugs that limit the risk of severe and life-threatening bleeding. Herein, we report the first cyclic peptide-based FXI inhibitor that selectively an ...

Generation of a Large Peptide Phage Display Library by Self-Ligation of Whole-Plasmid PCR Product

Christian Heinis, Xudong Kong, Kaycie Marie Butler, Vanessa Carle, Cristina Diaz Perlas

The success of phage display, used for developing target-specific binders based on peptides and proteins, depends on the size and diversity of the library screened, but generating large libraries of phage-encoded polypeptides remains challenging. New pepti ...

Cyclic peptide FXII inhibitor provides safe anticoagulation in a thrombosis model and in artificial lungs

Christian Heinis, Jonas Alfred Karl Wilbs, Simon Jan Middendorp, Xudong Kong, Christina Lamers, Patrick Andreas Gonschorek

Inhibiting thrombosis without generating bleeding risks is a major challenge in medicine. A promising solution may be the inhibition of coagulation factor XII (FXII), because its knock-out or inhibition in animals reduced thrombosis without causing abnorma ...

De novo development of proteolytically resistant therapeutic peptides for oral administration

Christian Heinis, Florence Pojer, Luciano Andres Abriata, Xudong Kong, Kaycie Marie Butler, Vanessa Carle, Jun Moriya

The oral administration of peptide drugs is hampered by their metabolic instability and limited intestinal uptake. Here, we describe a method for the generation of small target-specific peptides (less than 1,600 Da in size) that resist gastrointestinal pro ...

Engineered peptide macrocycles can inhibit matrix metalloproteinases with high selectivity

Christian Heinis, Jeremy Touati, Maola Khan Mohammad Golam, Michal Sabisz, Alice Baumann, Jonas Alfred Karl Wilbs, Xudong Kong, Kaycie Marie Butler

Matrix metalloproteinases (MMPs) are zinc‐dependent endopeptidases at the intersection of health and disease due to their involvement in processes such as tissue repair and immunity as well as cancer and inflammation. Because of the high structural conserv ...

Thiol-to-amine cyclization reaction enables screening of large libraries of macrocyclic compounds and the generation of sub-kilodalton ligands

Gerardo Turcatti, Jonathan Patrice Vesin, Christian Heinis, Van Manh Pham, Julien Bortoli Chapalay, Sangram Shivdas Kale, Xudong Kong, Milan Bergeron-Brlek, Patrick Andreas Gonschorek, João Miguel Franco Machado

Macrocyclic compounds are an attractive modality for drug development, but the limited availability of large, structurally diverse macrocyclic libraries hampers the discovery of leads. Here, we describe the discovery of efficient macrocyclization reactions ...

Precisely Regulated and Efficient Locking of Linear Peptides into Stable Multicyclic Topologies through a One-Pot Reaction

Christian Heinis, Xudong Kong

We report the discovery of a small phenyl molecule with four isosteric thiolate-reactive groups of sequentially varied reactivity. This molecule was exploited in combination with cysteine/penicillamine thiolates of different nucleophilic reactivity for pre ...

Phage Selection of Cyclic Peptides for Application in Research and Drug Development

Christian Heinis, Xudong Kong, Kaycie Marie Butler

Cyclic peptides can bind to protein targets with high affinities and selectivities, which makes them an attractive modality for the development of research reagents and therapeutics. Additional properties, including low inherent toxicity, efficient chemica ...

Bypassing bacterial infection in phage display by sequencing DNA released from phage particles

Christian Heinis, Camille Villequey, Xudong Kong

Phage display relies on a bacterial infection step in which the phage particles are replicated to perform multiple affinity selection rounds and to enable the identification of isolated clones by DNA sequencing. While this process is efficient for wild-typ ...
