title: Design, synthesis, and biological activity of novel purine and bicyclic pyrimidine factor Xa inhibitors.
abstract: The synthesis of amidinoaryloxy 9-benzyl-8-methyl-9H-purine, 7,8-dihydropteridine-6(5H)-one and 5,7-dihydropyrimido[4,5-b][1,4]oxazine-6-one inhibitors of Factor Xa is described. These compounds show nanomolar potency against FXa and maintain high selectivity over thrombin and trypsin.
