Molecular docking for the interaction between the anti-PD-L1 peptides and human PD-L1 protein (PDB ID: 5C3T). a Modeling of the interaction between CLP001 and PD-L1. b Modeling of the interaction between CLP002 and PD-L1. c Modeling of the interaction between CLP003 and PD-L1. d Modeling of the interaction between CLP004 and PD-L1. The PD-L1 residues responsible for peptide binding are highlighted in green. The binding residues for human PD-1 protein is highlighted in yellow. The overlapping PD-L1 residues for binding both anti-PD-L1 peptide and PD-1 protein are highlighted in pink
