Product Data:

Biological target: α7 nicotinic acetylcholine receptor (nAChR) agonist.
In vitro activity: Alpha 7 nAChRs are expressed in brain regions associated with cognitive function, regulate cholinergic neurotransmission and have been shown to be down regulated in both schizophrenia and Alzheimer's disease. Herein a novel, potent small molecule agonist of the alpha 7 nAChR, SEN12333/WAY-317538 was reported. This compound is a selective agonist of the alpha(7) nAChR with excellent in vitro and in vivo profiles, excellent brain penetration and oral bioavailability, and demonstrates in vivo efficacy in multiple behavioural cognition models. The SAR and biological evaluation of this series of compounds are discussed.
