Figure 4.

600 MHz ¹H NMR STD spectra obtained for a 50:1 mixture of 1–3 with WGA (conditions: 30 μm protein and 1.5 mm ligand at 310 K). The extracted STD values are gathered in the schematic drawings of 1 and 2 (top). The epitope mapping is also described with the corresponding color code. The STD control of the ligand without WGA is shown in the bottom right panel. The on‐resonance frequency for generation of the STD effects was set at δ=7.3 ppm, which corresponds to the aromatic protein resonance region.
