Varenicline (Chantix®; Fig. 4) is prescribed as an adjunct medication in smoking cessation therapy and is thought to exert its effects as a partial agonist at α4β2 nAChRs and as a full agonist at α7 nAChRs [211, 212]. PubMed:28391535
For example, DHβE (at nM concentrations) blocks α4β2 and α3β2 nAChRs but is much less potent at α3β4 and α7 nAChRs expressed in Xenopus oocytes (e.g., [134–137]). PubMed:28391535
