Toward a Novel Class of Antithrombotic Compounds with Dual Function. Discovery of 1,4-Benzoxazin-3(4H)-one Derivatives Possessing Thrombin Inhibitory and Fibrinogen Receptor Antagonistic Activities

A novel class of potential antithrombotic compounds with moderate thrombin inhibitory and fibrinogen receptor antagonistic activity is described. Combination of anticoagulant and antiaggregatory activity in the same molecular entity is presented as a new promising approach in the search for novel antithrombotic agents.
