Abstract

A variety of P4 motifs have been examined to increase the binding affinity and in vitro anticoagulant potency of our biphenyl 1-(2-naphthyl)-1H-pyrazole-5-carboxylamide-based fXa inhibitors. Highly potent 2-naphthyl-P1 fXa inhibitors (Ki≤ 2 nM) with improved in vitro anticoagulant activity (2× TG≤ 1 μM) and respectable pharmacokinetic properties have been discovered.
