MK 0777 is a selective GABAA α2/3 receptor partial agonist, for potential use in the treatment of Schizophrenia, Anxiety Disorder, and Generalized Anxiety Disorder. MK-0777 is functionally selective for the α2 and α3 subunits, with virtually no activity for the α1 and α5 subunits. Therefore, MK-0777 cause less sedation, interact less with alcohol, and exhibit less abuse potential and physical dependence than benzodiazepines. Unfortunately, in clinical trials, MK-0777 has little benefit for cognitive impairments in people with schizophrenia and anxiety disorder.
