Flow chart of virtual screening methodology. The final docked binding energy, which consists of the final intermolecular energy of the complex plus the final internal energy of the ligand, was obtained from Autodock3. The average X-Score is an average of three similar scoring functions that calculate hydrophobic contribution differently. The following scoring functions were evaluated in SYBYL (G Score, PMF Score, D Score, and ChemScore), then CSCORE was used to obtain a consensus score.
