Ligand of translocator protein (TSPO, peripheral benzodiazepine receptor)
Exhibits high affinity for TSPO in rat whole brain (Ki = 0.297 nM), and high potency against human and rat glial TSPO (IC50 values are 2.73 and 3.04 nM respectively)
Displays no noticeable binding to a number of other receptors, transporters or ion channels
Also displays anxiolytic and antidepressant effects in rodent models, without inducing benzodiazepine-like adverse effects.
