PHA-543,613 is a drug that acts as a potent and selective agonist for the α7 subtype of neural nicotinic acetylcholine receptors, with a high level of brain penetration and good oral bioavailability. It is under development as a possible treatment for cognitive deficits in schizophrenia.[1] It reduces excitotoxicity[2] and protects striatal dopaminergic neurons in rat models.[3] It also potentiates cognitive enhancement from memantine,[4][5] decreases dynorphin release[6] and inhibits GSK-B3.[7]
