PNU-282,987 is a drug that acts as a potent and selective agonist for the α7 subtype of neural nicotinic acetylcholine receptors.[1][2] In animal studies, it shows nootropic effects, and derivatives may be useful in the treatment of schizophrenia,[3][4] although PNU-282,987 is not suitable for use in humans because of excessive inhibition of the hERG antitarget.[5]
