Biological Activity for TC 2559 difumarate

TC 2559 difumarate is a subtype-selective partial agonist for α4β2 nicotinic acetylcholine receptors (EC50 values are 0.18, 12.5, 14.0, > 30, > 100 and > 100 μM for α4β2, α4β4, α2β4, α3β4, α3β2 and α7 receptor subtypes respectively). Displays selectivity for (α4)2(β2)3 receptor stoichiometry and enhanced CNS-PNS selectivity ratio. Attenuates scopolamine-induced cognitive deficits in a step-through passive avoidance task.
