Abstract

2-Cyano-6-fluorophenylacetamide was explored as a novel P2 scaffold in the design of thrombin inhibitors. Optimization around this structural motif culminated in 14, which is a potent thrombin inhibitor (Ki= 1.2 nM) that exhibits robust efficacy in canine anticoagulation and thrombosis models upon oral administration.
