Fig. 4From: Leveraging structural and 2D-QSAR to investigate the role of functional group substitutions, conserved surface residues and desolvation in triggering the small molecule-induced dimerization of hPD-L1The estimated total AMBER/MM-GBSA (kcal/mol) binding energies of the protein ligand complexes. The binding energies were estimated according to two different scenarios; a the small molecule ligand is binding to a receptor composed of the PD-L1 dimer and b the second chain of the dimer (chainB) is treated as a ligand whereas chainA complex with the small molecule was treated as the receptorBack to article page
