Several efforts have been described targeting the active form of the enzyme, FXIa. Herein we disclose our efforts to identify potent, selective, and orally bioavailable inhibitors of FXIa. Compound 1, identified from a diverse library of internal serine protease inhibitors, was originally designed as a complement Factor D inhibitor and exhibited sub-micromolar FXIa activity and an encouraging ADME profile while being devoid of peptidomimetic architecture. Optimization of interactions in the S1, S1beta, and S1` pockets of FXIa through a combination of structure-based drug design and traditional medicinal chemistry led to the discovery of compound 23 with sub-nanomolar potency on FXIa, enhanced selectivity over other coagulation proteases, and a pre-clinical PK profile consistent with bid dosing in patients.
