Popis: Factor XIa inhibitors have been identified to have potential as anticoagulants with robust efficacy and low bleeding risks. In light of their significance and the availability of their 3-D X-ray data in the PDB, we present molecular docking studies carried out with a view to obtain docking protocols that will successfully reproduce the experimentally observed protein-ligand interactions in the case of various X-ray ligands. In this context, we have specifically investigated the efficacy of various cross-docking protocols in reproducing experimental data. Our studies demonstrate that an ensemble of the three apo proteins is capable of accurately docking a majority of the X-ray ligands accurately without invoking any additional conformational flexibility than that present in their experimental structures. Further, we demonstrate that such an ensemble is successfully able to enrich a collection of known active factor XIa inhibitors embedded in a decoy database of drug-like molecules.
