In addition to this discovery, a clear preference for the (S)-configuration was confirmed.

Vitamin K antagonists (VKA) are a group of substances that reduce blood clotting by reducing the action of vitamin K. The term "vitamin K antagonist" is technically a misnomer, as the drugs do not directly antagonize the action of ...
Andexanet alfa is a biologic agent, a recombinant modified version of human activated factor X (FXa). [17] Andexanet alfa differs from native FXa due to the removal of a 34 residue fragment that contains the Gla domain. This modification reduces andexanet alfa's anticoagulant potential.
