Structural optimization identified triazole-based benzoic acids as optimal P2′ fragments.

Extensive molecular dynamics simulations and free energy calculations revealed that electrostatic interactions with varied residues near the binding site, particularly the loop at the bottom of the S2’ pocket (IP-loop), are critical factors contributing to the improved selectivity over PKa. Calculations of electrostatic potential (ESP) surfaces illustrated that FXIa forms a more positive ESP than PKa, thrombin, and FXa, which attracts the carboxylic acid group of the designed compounds, enhancing both potency and selectivity.
