Left: Best macrocyclic RMSD achieved by ETKDG and BRIKARD for each macrocyclic target ligand (BACE_1 to BACE_19). The color of the points reflects the “group” of the macrocycles. Right: Native structures of the macrocyclic target ligands, grouped by the properties of their main ring. “Green” ligands (BACE_2– 5, 11) have two peptide bonds (one of them near a small nitrogen-sidechain); “orange” ligands (BACE_1, 6, and 7) have two peptide bonds (one of them near a large nitrogen-sidechain); “blue” ligands (BACE_8, 9, 10, 12–19) have one peptide bond
