Figure 1The syntheses of the ligands PR-924, 9, 14, 16, 17 and 18 have been described previously (de Bruin et al, 2014). All ligands share the peptide scaffold shown in the upper left corner with P1, P2 and P3 side chains and an N-cap; they are equipped with a l-Ala (stereochemistry (S)) or d-Ala (stereochemistry (R)) residue at P3 (red) and either an N-acylmorpholine or a 3-methyl-1H-indene group (green). Furthermore, compounds differ in their P2 residue (either methoxytyrosine or tryptophane; blue).
