Values shown are means ± SEM. 5-HT transporter affinity was determined by competition with 3H-paroxetine binding in rat cortical membranes and function was determined by the ability of compounds to inhibit 3H-5-HT uptake into JAR cells expressing the human 5-HT transporter. 5-HT1A affinity and function were obtained using recombinant human 5-HT1A receptors. Receptor affinity was determined using 3H-8-OHDPAT binding and antagonism was assessed using both an adenylate cyclase assay and a GTPγS assay. See methods for full details.

SSRI, 5-HT selective reuptake inhibitor.
