Energy components of the compounds calculated by the MM/GBSA and MM/PBSA in the PLpro. Energy components of GRL0617 in the MM/GBSA (A) and MM/PBSA (B) analysis and its binding free energy (ΔGb) decomposed to the enthalpy (ΔH) and entropy (-TΔS) terms in the MM/GBSA (C) and MM/PBSA (D) calculations. Correspondingly, energy components and binding free energy (ΔGb) terms for CHA-12 in the MM/GBSA and the MM/PBSA calculations are respectively illustrated in (E–H). Energy components and binding free energy (ΔGb) terms for CHA-37 in the MM/GBSA and MM/PBSA calculations are respectively illustrated in (I–L). Energy components and binding free energy (ΔGb) terms for hirsutenone in the MM/GBSA and MM/PBSA calculations are respectively illustrated in (M–P). VDWAALS: van der Waals energy, EEL: electrostatic energy, EGB: polar solvation energy calculated by the MM/GBSA, ESURF: non-polar solvation energy calculated by the MM/GBSA, EPB: polar solvation energy calculated by the MM/PBSA, ENPOLAR: non-polar solvation energy calculated by the MM/PBSA.
