Known limitations of the predictions mentioned above, include for example, fixed docking-cavities, eliminated water molecules, chemotypedependent unreliabilities, and docking discrepancies due to force-field energy minimization algorithms (despite selecting mmff94s and mmff94s+ force-fields to best maintain molecular geometries after docking). Additionally, any exploration of the vast chemical/chemotype space, including the ones reported here, will always be incomplete. Some of the limitations together with unexpected in vivo physiological variables, may still limit the accuracy of these predictions.
