Abstract

Neuronal nicotinic receptors have been implicated in several diseases and disorders such as autism, Alzheimer's disease, Parkinson's disease, epilepsy, and various forms of addiction. To understand the role of nicotinic receptors in these conditions, it would be beneficial to have selective molecules that target specific nicotinic receptors in vitro and in vivo. Our laboratory has previously identified novel negative allosteric modulators of human alpha4beta2 (Halpha4beta2) and human alpha3beta4 (Halpha3beta4) nicotinic receptors. The effects of novel sulfonylpiperazine analogues that act as negative allosteric modulators on both Halpha4beta2 nAChRs and Halpha3beta4 nAChRs were investigated. This work, through structure-activity relationship (SAR) studies, describes the chemical features of these molecules that are important for both potency and selectivity on Halpha4beta2 nAChRs.
