The race to an orally active Factor Xa inhibitor: recent advances

Current Opinion in Drug Discovery & Development

Abstract

Factor Xa (fXa) is a key enzyme in the coagulation cascade and an essential component of the prothrombinase complex, which activates prothrombin to thrombin, leading to fibrin clot formation. In the search for a more effective and safer orally active anticoagulant, fXa has emerged as a major target for potential therapeutic applications in the treatment and prevention of thrombosis. This review focuses on recent advances in the chemistry of drug design and lead optimization of orally bioavailable fXa inhibitors. Many of these orally active fXa inhibitors are currently in clinical trials and are anticipated to change the landscape of thrombosis therapy.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
