Fig. 6. Representative bimane emission spectra of selected peptidomimetics with significant effects in the cAMP assay. The responses of the linear and cyclic peptidomimetic pairs 6C/10C, 7C/11C, 8C/12C, 8B/12B and 9B/13B were normalised to that of the unliganded β2AR alone (black solid line). The peptides were tested at 20 μM (n = 2 of measurements in triplicate) in the absence (pink solid line) and the presence (blue solid line) of ISO 10 μM (grey solid line).
