PWZ-029 is a benzodiazepine derivative drug with nootropic effects. It acts as a subtype-selective, mixed agonist-inverse agonist at the benzodiazepine binding site on the GABA_A receptor, acting as a partial inverse agonist at the α₅ subtype and a weak partial agonist at the α₃ subtype. This gives it a mixed pharmacological profile, producing at low doses memory-enhancing effects but with no convulsant or anxiogenic effects or muscle weakness, although at higher doses it produces some sedative effects.
