Used in neuroscience research to study nicotinic acetylcholine receptors, particularly the β4 subtype. Helps investigate receptor function and signaling in neuronal pathways. Explored for potential cognitive enhancement and neuroprotection in models of neurodegenerative diseases. Also serves as a pharmacological tool to differentiate subtypes of nicotinic receptors in vitro and in vivo. Shows selectivity over other receptor types, making it valuable for targeted studies.
