Abstract

The identification of selective benzodiazepine site ligands, endowed with anxiolytic and anti‐hyperalgesic action, is a relevant opportunity for the treatment of pain syndromes. Previously, we selected a compound with a promising anti‐hyperalgesic profile, the 3‐iodo‐8‐benzylaminopyrazolo [5,1‐c][1,2,4]benzotriazine 5‐oxide. Aimed to verify the structure–activity relationship, the corresponding 7‐arylakylamino derivatives were synthesized. Compounds were tested for their affinity at GABAA‐receptor subtype; the compound 12 was further investigated in animal models of anxiety and persistent pain.
