Edoxaban (Savaysa): A Factor Xa Inhibitor.
INTRODUCTION Atrial fi brillation (AF), the most common cardiac arrhythmia, is encountered in clinical practice with ever-increasing frequency.1 Older data suggest that the lifetime risk of AF in men and women older than 40 years of age is approximately one in four.2 The prevalence of AF has most likely increased due to the aging of the “baby-boomers” (AF is overwhelmingly a disease of age) and...
متن کاملA New Oral Direct Factor Xa Inhibitor
Edoxaban is an oral direct factor Xa inhibitor that is currently undergoing investigation in phase III clinical trials for the prevention of stroke in patients with atrial fibrillation (AF) and for the prevention and treatment of venous thromboembolic events (VTE). Factor Xa is an attractive target for anticoagulant treatment, as it is the primary and rate-limiting source of amplification in th...
متن کاملSelective factor Xa inhibition by recombinant antistasin prevents vascular graft thrombosis in baboons.
A baboon model of high-shear, platelet-dependent vascular graft thrombosis was used to assess the antithrombotic effect of recombinant antistasin (rATS), a 119-amino acid protein with selective, subnanomolar inhibitory potency against coagulation factor Xa. In this model, a Dacron vascular graft segment of a femoral arteriovenous (AV) shunt provided the thrombogenic stimulus. Antithrombotic eff...
متن کاملAncylostoma caninum anticoagulant peptide: a hookworm-derived inhibitor of human coagulation factor Xa.
Human hookworm infection is a major cause of gastrointestinal blood loss and iron deficiency anemia, affecting up to one billion people in the developing world. These soil-transmitted helminths cause blood loss during attachment to the intestinal mucosa by lacerating capillaries and ingesting extravasated blood. We have isolated the major anticoagulant used by adult worms to facilitate feeding ...
متن کاملX-ray structure of antistasin at 1.9 A resolution and its modelled complex with blood coagulation factor Xa.
The three-dimensional structure of antistasin, a potent inhibitor of blood coagulation factor Xa, from the Mexican leech Haementeria officinalis was determined at 1.9 A resolution by X-ray crystallography. The structure reveals a novel protein fold composed of two homologous domains, each resembling the structure of hirustasin, a related 55-residue protease inhibitor. However, hirustasin has a ...
