Anticoagulation via anti-Factor Xa inhibition
Lupus, 2006Hospital-acquired deep vein thrombosis (DVT) affects 10-25% of medical patients and up to 60% of surgical patients. While thromboprophylaxis is without a doubt under utilized in the hospital setting, there is also a need for more efficacious agents. Fondaparinux, the first of a new class of agents Factor Xa inhibitiors, has recently come into clinical

Heterogeneity of Synthetic Factor Xa Inhibitors
Current Pharmaceutical Design, 2005Heparins and vitamin K antagonists are the landmarks of antithrombotic treatment. Both of them were discovered by serendipity; they are multi-targeted drugs and share several limitations. New molecules have been designed in order to be both more selective concerning their biological target and more homogeneous in their biochemical structure aiming at ...

Hämostaseologie, 2009
SummaryOral factor Xa (FXa) inhibitors are a promising alternative to current anticoagulants. This paper reviews the latest developments of oral direct FXa inhibitors and focuses on those which have been approved for the prevention of venous thromboembolism (VTE) after total hip or knee replacement or are in advanced development and have passed phase ...

Tetrahydro-isoquinoline-Based Factor Xa Inhibitors
Journal of Medicinal Chemistry, 1998Derivatives of (2-amidino-1,2,3, 4-tetrahydro-isoquinolin-7-yloxy)phenylacetic acid (TIPAC) were developed as inhibitors of factor Xa (fXa). The compounds are prepared using 15 synthetic steps on average. The most potent compounds (14, 17, 22-26) display inhibition constants of Ki = 21-55 nM but do not inhibit thrombin (Ki = 5->100 microM) and only ...

Phenyltriazolinones as potent factor Xa inhibitors
Bioorganic & Medicinal Chemistry Letters, 2010We have discovered that phenyltriazolinone is a novel and potent P1 moiety for coagulation factor Xa. X-ray structures of the inhibitors with a phenyltriazolinone in the P1 position revealed that the side chain of Asp189 has reoriented resulting in a novel S1 binding pocket which is larger in size to accommodate the phenyltriazolinone P1 substrate.

Thrombin occupies a central position in thrombus formation and recently has been a target for the development of anticoagulant agents. As is well known, blood coagulation operates as a cascade or multiple enzymatic amplification process. In the classical intrinsic pathway, factor (f) IXa in the presence of fVIIIa, Ca2+ and phospholipid converts fX to ...

Synthetic inhibitors of coagulation factor Xa
Expert Opinion on Investigational Drugs, 1999The antithrombotic efficacy of low molecular weight heparins suggest that specific inhibition of blood coagulation factor Xa (fXa) is an appropriate target for drug discovery. Clinical evidence also supports the effectiveness of warfarin, an orally bioavailable non-specific anticoagulant.

Heparin-Binding Exosite of Factor Xa
Trends in Cardiovascular Medicine, 2000Recent studies have indicated that the basic residues Arg(93), Lys(96), Arg(125), Arg(165), Lys(169), Lys(236), and Arg(240) (chymotrypsin numbering) constitute an exosite in the catalytic domain of factor Xa that can effectively bind heparin only if the acidic N-terminal Gla domain of the proteinase was neutralized by physiological levels of calcium ...
