Facinicline (MEM-63908 or R-4996) is a selective nicotinic alpha-7 receptor (α7nAChR) partial agonist. It also has properties of a serotonin 3 receptor antagonist. It has hydrochloride form: RG3487 (formerly MEM3454). Facinicline enhances DA efflux by nAChR stimulation, whereas ACh efflux is primarily mediated via 5-HT3 receptor antagonism. It improves cognition and sensorimotor gating in rodents. It has been tested in Alzheimer's disease and cognitive symptoms of schizophrenia.
