Description: Selective α4β2 nAChR partial agonist; orally active
Chemical Name: 7,8,9,10-Tetrahydro-6,10-methano-6H-pyrazino[2,3-h][3]benzazepine tartrate
Purity: ≥99% (HPLC)
Biological Activity for Varenicline tartrate
Varenicline tartrate is an orally active, subtype-selective partial agonist at α4β2 nicotinic receptors (Ki values are 0.06, 240, 322 and 3540 nM for α4β2, α3β4, α7, α1βγδ receptors respectively). Reduces nicotine-evoked dopamine release in vitro and decreases nicotine self-administration in vivo. Also potently activates PSAM4-5-HT3 and PSAM4-GlyR chimeric ion channels (EC50 values are 4 and 1.6 nM, respectively)
