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

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

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 ...

Tissue Factor-Independent Coagulation Correlates with Clinical Phenotype in Factor XI Deficiency and Replacement Therapy

Christian Heinis, Vanessa Carle, Alessandro Aliotta

Background In factor XI (FXI) deficiency, bleeding cannot be predicted by routine analyses. Since FXI is involved in tissue factor (TF)-independent propagation loop of coagulation, we hypothesized that investigating the spatiotemporal separated phases of c ...

Patchy Amphiphilic Dendrimers Bind Adenovirus and Control Its Host Interactions and in Vivo Distribution

Francesco Stellacci, Weina Liu

The surface of proteins is heterogeneous with sophisticated but precise hydrophobic and hydrophilic patches, which is essential for their diverse biological functions. To emulate such distinct surface patterns on macromolecules, we used rigid spherical syn ...

Development of cyclic peptide inhibitors of coagulation factor XIa for safer anticoagulation

Vanessa Carle

Hemostasis is a complex physiological process responsible for the prevention of blood loss caused by vascular injury. The dysregulation of this delicate mechanism can lead to thromboembolic diseases, the leading cause of death worldwide. Anticoagulants are ...

Development of cyclic peptide inhibitors of coagulation factor XII and matrix metalloproteinase 2

Jonas Alfred Karl Wilbs

Peptides represent a promising molecular class for drug development. They combine several strengths of small molecules (e.g. efficient tissue diffusion, low immunogenicity and access to chemical synthesis) and key properties of biologics such as monoclonal ...

Peptide macrocycle inhibitor of coagulation factor XII with subnanomolar affinity and high target selectivity

Christian Heinis, Jonas Alfred Karl Wilbs, Simon Jan Middendorp

Factor XII (FXII) is a plasma protease that has emerged in recent years as a potential target to treat or prevent pathological thrombosis, to inhibit contact activation in extracorporeal circulation, and to treat the swelling disorder hereditary angioedema ...

Improving the binding affinity of in-vitro-evolved cyclic peptides by inserting atoms into the macrocycle backbone

Christian Heinis, Jonas Alfred Karl Wilbs, Simon Jan Middendorp

Cyclic peptides binding to targets of interest can be generated efficiently with powerful in vitro display techniques, such as phage display or mRNA display. The cyclic peptide libraries screened with these methods are generated by altering in a combinator ...

Novel inhibitors of the enzyme activated factor xii (fxiia)

Christian Heinis, Jonas Alfred Karl Wilbs, Vanessa Baeriswyl, Simon Jan Middendorp

The present invention relates to a bicyclic inhibitor of the coagulation enzyme activated factor XII (FXIIa) comprising or consisting of the peptide (X1)(X2)(X3)n(X4)(X5)(X6)m(X7)(X9)l(X10)(X11)(X12)(X13)(X14)k(X15)(X16), wherein (X1) is present or absent ...

A Synthetic Factor XIIa Inhibitor Blocks Selectively Intrinsic Coagulation Initiation

Christian Heinis, Shiyu Chen, Alessandro Zorzi, Vanessa Baeriswyl, Luca Bologna

Coagulation factor XII (FXII) inhibitors are of interest for the study of the protease in the intrinsic coagulation pathway, for the suppression of contact activation in blood coagulation assays, and they have potential application in antithrombotic therap ...

Identification of target-binding peptide motifs by high-throughput sequencing of phage-selected peptides

Christian Heinis, Inmaculada Rentero Rebollo, Vanessa Baeriswyl, Michal Sabisz

High-throughput sequencing was previously applied to phage-selected peptides in order to gain insight into the abundance and diversity of isolated peptides. Herein we developed a procedure to efficiently compare the sequences of large numbers of phage-sele ...
