Polyanionic Amphiphilic Dendritic Polyglycerols as Broad-Spectrum Viral Inhibitors with a Virucidal Mechanism

Francesco Stellacci, Valeria Cagno, Matteo Gasbarri

Heparin has been known to be a broad-spectrum inhibitor of viral infection for almost 70 years, and it has been used as a medication for almost 90 years due to its anticoagulant effect. This nontoxic biocompatible polymer efficiently binds to many types of ...

Programmable DARPin-based receptors for the detection of thrombotic markers

Leo Scheller, Yujia Wang, Haifeng Ye

Cellular therapies remain constrained by the limited availability of sensors for disease markers. Here we present an integrated target-to-receptor pipeline for constructing a customizable advanced modular bispecific extracellular receptor (AMBER) that comb ...

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 ...

De novo development of proteolytically resistant therapeutic peptides for oral administration

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

Heart Rate Variability Triangular Index as a Predictor of Cardiovascular Mortality in Patients With Atrial Fibrillation

Jean-Marc Vesin, Vincent Schlageter

Background Impaired heart rate variability (HRV) is associated with increased mortality in sinus rhythm. However, HRV has not been systematically assessed in patients with atrial fibrillation (AF). We hypothesized that parameters of HRV may be predictive o ...

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 ...

From Patients to Platelets and Back Again: Pharmacological Approaches to Glycoprotein VI, a Thrilling Antithrombotic Target with Minor Bleeding Risks

Nikolaos Stergiopoulos, Augusto Martins Lima

Despite significant advances in the treatment of thrombogenic diseases, antiplatelet therapies are still associated with a high bleeding risk. Consequently, potential benefits of preventing thromboembolic events by pharmacological agents need to be balance ...

An optimized and validated 384-well plate assay to test platelet function in a high-throughput screening format

Nikolaos Stergiopoulos, Olivier Burri, Marc Chambon, Rodrigo Araujo Fraga Da Silva, Fabiana Pereira Da Costa Fraga, Julien Bortoli Chapalay, Augusto Martins Lima, Maiia Bragina

Despite significant advances in the treatment of cardiovascular diseases, antiplatelet therapies are still associated with a high risk of hemorrhage. In order to develop new drugs, methods to measure platelet function must be adapted for the high-throughpu ...

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 ...

Acylated heptapeptide binds albumin with high affinity and application as tag furnishes long-acting peptides

Christian Heinis, Alessandro Zorzi, Jonas Alfred Karl Wilbs, Simon Jan Middendorp, Kaycie Marie Butler

The rapid renal clearance of peptides in vivo limits this attractive platform for the treatment of a broad range of diseases that require prolonged drug half-lives. An intriguing approach for extending peptide circulation times works through a 'piggy-back' ...

Microdevice for Sedimentation-based Separation of Blood Microsamples at the Point of Collection

David Forchelet

Laboratory blood testing plays a central role in current diagnostics and therapeutical decisions. Thus, errors have a direct impact on care quality and cost. The majority of errors occur in the pre-analytical phase, when samples are collected, stored and p ...

Dual Targeting of the Autophagic Regulatory Circuitry in Gliomas with Repurposed Drugs Elicits Cell-Lethal Autophagy and Therapeutic Benefit

Douglas Hanahan, Aristea Massaras, Ksenya Shchors

The associations of tricyclic antidepressants (TCAs) with reduced incidence of gliomas and elevated autophagy in glioma cells motivated investigation in mouse models of gliomagenesis. First, we established that imipramine, a TCA, increased autophagy and co ...

Portable Technologies for Self-Monitoring of Coagulation Time: A Review

Philippe Renaud, Lynda Metref

Anti-coagulation treatments are required for medical conditions that become more and more frequent with the ageing of the population in developed countries (atrial fibrillation, deep-venous thrombosis, heart prosthetic valves, etc.). These treatments gener ...

Pattern-Based Sensing of Sulfated Glycosaminoglycans with a Dynamic Mixture of Iron Complexes

Kay Severin

A dynamic mixture of iron complexes was used as a colorimetric sensor for sulfated glycosaminoglycans. The sensing ensemble was prepared by mixing [FeCl2(H2O)4] with dipicolylamine, the functionalized bipyridyl ligand N-(6-aminohexyl)-4'-methyl-2,2'-bipyri ...

On-chip thermopneumatic actuation system for coagulation time measurement

Philippe Renaud, Lynda Metref, Pierre Lemaire, François Bianchi

This work reports the demonstration of a thermopneumatic microfluidic actuator used to determine blood coagulation time. In this new system, the detection principle is the obstruction of a microfluidic channel by clotted blood. The sample actuation is done ...
