(a) The tunneling spectra of several 2C-X class agonists as well as theirmolecular structures. (b) The inverse of the median effective concentration forthe 2C-X class agonists plotted against the tunneling probability within theregion at 1500 ± 35 cm−1. Thetrend of tunneling intensity follows roughly the trend of theagonist’s potency at the 5-HT2A receptor.
