Cat.No. 5281 - AC 5216 | C23H23N5O2 | CAS No. 226954-04-7
Description: Selective TSPO ligand
Alternative Names: XBD173
Chemical Name: N-Ethyl-7,8-dihydro-7-methyl-8-oxo-2-phenyl-N-(phenylmethyl)-9H-purine-9-acetamide
Purity: ≥98% (HPLC)

Biological Activity

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.
