PWZ-029

PWZ-029 is a benzodiazepine derivative drug with nootropic effects developed by WiSys,[1] It acts as a subtype-selective, mixed agonist-inverse agonist at the benzodiazepine binding site on the GABAA 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.[2]
