RJR-2429 is a drug that acts as an agonist at neural nicotinic acetylcholine receptors, binding to both the α3β4 and the α4β2 subtypes. RJR-2429 is stronger than nicotine but weaker than epibatidine in most assays, and with high affinity for both α3β4 and α4β2 subtypes, as well as the less studied α1βγδ subtype.[1][2][3]
