In an effort to identify a potential back-up to apixaban (Eliquie (R)), we explored a series of diversified P4 moieties. Several analogs with substituted gem-dimethyl moieties replacing the terminal lactam of apixaban were identified which demonstrated potent FXa binding affinity (FXa K-i), good human plasma anticoagulant activity (PT EC2x), cell permeability, and oral bioavailability.
