Structural Mechanism of an Efficacy Photoswitch Targeting the β2‐adrenergic Receptor
Angewandte Chemie International Edition, EarlyView.Time‐resolved structures from x‐ray free‐electron laser measurements combined with cellular assays demonstrate how the photoswitchable β‐blocker photoazolol‐1 acts as an efficacy switch of β2‐adrenergic receptor function. Light‐induced ligand repositioning shifts activity from inverse agonism toward neutral antagonism by altering local helical ...
