Abstract
Glide is a ligand docking program for predicting protein?ligand binding modes and ranking ligands via high?throughput virtual screening. Glide utilizes two different scoring functions, SP and XP GlideScore, to rank?order compounds. Three modes of sampling ligand conformational and positional degrees of freedom are available to determine the optimal ligand orientation relative to a rigid protein receptor geometry. This unit presents protocols for flexible ligand docking with Glide, optionally including ligand constraints or ligand molecular similarities.
Keywords: ligand docking; protein?ligand interactions; protein?ligand binding

Figure 8.12.19 Examples of well‐docked and poorly‐docked ligands from docking co‐crystallized ligands back into their prepared proteins. Ligands in blue are the native structures and those in green are the top‐ranked docked structures. RMSDs for docked 3tpi, 1apt, 1tmn, and 1dhf ligands are 0.44, 1.26, 1.97, and 5.44 Å, respectively.

Figure 8.12.20 Three hypothetical enrichment curves. In the high early enrichment example 90% of known active ligands are found before 10% of the known decoy ligands were recovered. In the moderate early enrichment example 30% of known active ligands were found before 10% of the known decoy ligands were recovered. These results stand in contrast to what would be expected by chance, shown in the even distribution curve. View Image
