Bradanicline is a highly selective α7 nicotinic acetylcholine receptor (nAChR) agonist (humanα7 nAChR: EC50=17 nM; Ki= 1.4 nM). Bradanicline is used for the research of cognitive disorders[1][2].
Bradanicline is more than a thousand-fold separation between the affinities for the α7 and α4β2 receptor subtypes and has no detectable effects on muscle or ganglionic nicotinic receptor subtypes, indicating a marked selectivity for the central nervous system over the peripheral nervous system[1].
Bradanicline (0.1-1 mg/kg) shows efficacy in animal models of the positive and negative symptoms and cognitive dysfunction of schizophrenia[2].
