Poses for all SYK ligands were generated successfully for all docking protocols. Use of both the fixed core constraint and MCS with Glide resulted in consistent ligand positioning (Figure ). The MCS protocol was able to further consistently predict the orientation of the phenol ring, whereas some ring flips were observed in the core-constrained protocol. Without a core constraint, the vanilla Glide poses showed larger diversity in core placement, in one case resulting in a flipped ligand. For AutoDock Vina, the vanilla protocol successfully placed the hinge in the orientation matching that of the docked/modelled poses in all cases, whilst the MCS filtering refined the overall alignment, in particular for the phenol ring placement.
