AWD 131-138 is a partial agonist of benzodiazepine receptor [1].

Benzodiazepine (BZD) is a psychoactive drug and acts as positive allosteric modulators of the inhibitory neurotransmitter GABA by binding to a recognition site (BZD receptor) of the GABAA receptor chloride ionophore complex [1].

AWD 131-138 is a partial benzodiazepine receptor agonist with anticonvulsant and anxiolytic activity [1]. In Xenopus oocytes expressed recombinant γ-aminobutyric acid A (GABAA) receptors of ɑ1β2γ2, ɑ1β3γ2, ɑ2β2γ2, ɑ3β2γ2 and ɑ5β2γ2, AWD 131-138 stimulated GABA currents in a dose-dependent way and acts at the binding site for benzodiazepines. AWD 131-138 (10 μM) stimulated GABA currents up to 12-21% of the maximal stimulation achieved by diazepam [2].

In a dog seizure model, AWD 131-138 increased the pentylenetetrazole (PTZ) seizure threshold. AWD 131-138 (5 or 40 mg/kg) caused relatively mild abstinence symptoms, particularly at the lower dosage. In dogs with newly diagnosed epilepsy, AWD 131-138 significantly reduced seizure frequency and severity [3].
