MedKoo Cat#: 326878 | Name: Pazinaclone

Description:

WARNING: This product is for research use only, not for human or veterinary use.

Pazinaclone, also known as A-77000; DN-2327, is a sedative and anxiolytic drug in the cyclopyrrolone family of drugs. Some other cyclopyrrolone drugs include zopiclone and eszopiclone. Pazinaclone has a very similar pharmacological profile to the benzodiazepines including sedative and anxiolytic properties, but with less amnestic effects, and at low doses it is a relatively selective anxiolytic, with sedative effects only appearing at higher doses. Pazinaclone produces its sedative and anxiolytic effects by acting as a partial agonist at GABAA benzodiazepine receptors, although pazinaclone is more subtype-selective than most benzodiazepines.
