Vibrational spectroscopy analysis of ligand efficacy in human M2 muscarinic acetylcholine receptor (M2R)

Abstract

Katayama et al. report a vibrational spectroscopic study using ATR–FTIR of the human M2 muscarinic acetylcholine receptor (M2R). Their work involves an extensive comparison of agonists, antagonists, and inverse agonists, in which they show that they C = O stretching amide–I band is correlated with the ligand binding efficiency.
