Total Ligand Grid Free Energies (LGFE, kcal/mol) for JY-1-106 binding to Bcl-xL and Mcl-1 based on the minimization, Langevin Dynamics and Explicit Solvent MD simulation approaches along with LGFE group contributions summed over the aromatic and aliphatic functional groups for Bcl-xL and Mcl-1.
Results are presented for both forward (F) and backward (B) orientations of JY-1-106 and differences (Mcl-1 – Bcl-xL) are presented for all values. Values in paranthesis for the total LGFEs are standard errors.
