U-89843A (PNU-89843) is a sedative drug which acts as an agonist at GABAA receptors, specifically acting as a positive allosteric modulator selective for the α1, α3 and α6 subtypes.[1] It has sedative effects in animals but without causing ataxia, and also acts as an antioxidant and may have neuroprotective effects.[2] It was developed by a team at Upjohn in the 1990s.[3]
