Abstract
Negative connotations associated with the use of (-)-nicotine has limited medicinal chemistry research in the area of nAChRs [5]. However, recent evidence suggests that a diversity of nAChR subunits exist, that each subtype may be involved in mediating specific neurochemical/behaviors, and that these subtypes have a defined pharmacology that may be selectively targeted [1]. (+/-)-Epibatidine, GTS-21 and ABT-418 differentially interact with nAChR subtypes to elicit a diversity of behavioral effects including analgesia, neuroprotection and cognitive enhancement. These agents therefore represent important new pharmacological probes to dissect the nAChR subtype(s) mediating specific pharmacological responses to nAChR activation.
