... AZD7325 is a high affinity, selective modulator of the GABAA receptor system, with differential binding and modulatory properties dependent on the particular GABAA subtype. Binding affinity is high at GABAA α1, α2 and α3 (Ki of 0.5, 0.3 and 1.3 nM, respectively), but not GABA Aα5 (230 nM). Using who ...

Nicotinic agonist
A nicotinic agonist is a drug that mimics the action of acetylcholine (ACh) at nicotinic acetylcholine receptors (nAChRs). The nAChR is named for its affinity for nicotine.Examples include nicotine (by definition), acetylcholine (the endogenous agonist of nAChRs), choline, epibatidine, lobeline, varenicline and cytisine.
