Background:

(±)-Epibatidine is an alkaloid that has been found in Ecuadoran poison frog (E. tricolor) skin extracts and an agonist of α4β2 subunit-containing nicotinic acetylcholine receptors (nAChRs; K_i= 43 pM).^1,2It is selective for α4β2 subunit-containing nAChRs over α7 nAChRs (K_i= 230 nM).¹(±)-Epibatidine enhances⁸⁶Rb⁺flux in IMR-32 cells (EC₅₀= 7 nM) and induces dopamine release from rat striatal slices (EC₅₀= 0.4 nM), effects that can be reduced by the nAChR antagonist mecamylamine .In vivo, (±)-epibatidine induces analgesia in the hot plate test and the Straub-tail response in mice (ED₅₀s = 0.005 and 0.02 mg/kg, respectively).²
