Glide is also found to be more accurate than the Surflex method.
Dockovalent
Studies large virtual libraries of electrophilic small molecules. DOCKovalent exhaustively samples all poses and ligand conformations with respect to the covalent bond to the target nucleophile, constrained by ideal bond lengths and angles. DOCKovalent was used to prospectively screen compound libraries against three targets of therapeutic interest: AmpC β-lactamase, RSK2 kinase and JAK3 kinase. Multiple potent, reversible covalent inhibitors were found against all three targets. X-ray crystal structures of predicted ligands, and the occasional false negative, illuminated not only the method’s ability to prospectively identify ligands and to predict their structures, but also its limitations. Several of the new covalent ligands were tested in cell culture experiments that established biological efficacy and target engagement. To ensure that the method may be used by a broad community, it has been made available on an easy to use web server.

ProBiS-ligands
A web server for prediction of ligands based on detected local structural similarities in proteins. ProBiS-ligands requires a query protein structure or a query binding site, and this is first compared to proteins in the nr-PDB using the local structural alignment algorithm ProBiS, resulting in a list of similar representative protein structures that share similar 3D amino acid environments with the query protein. ProBiS-ligands provides an interactive environment in which users can explore the predicted protein–ligand complexes. One of the major advantages of ProBiS-ligands is that it allows transposition of ligands between protein structures irrespective of protein folding and with no prior knowledge of binding sites.
