Abstract
Herein, we describe the discovery
of inhibitors of norepinephrine
(NET) and dopamine (DAT) transporters with reduced activity relative
to serotonin transporters (SERT). Two compounds, <b>8b</b> and <b>21a</b>, along with nomifensine were tested in a rodent receptor
occupancy study and demonstrated dose-dependent displacement of radiolabeled
NET and DAT ligands. These compounds were efficacious in a rat forced
swim assay (model of depression) and also had activity in rat spontaneous
locomotion assay
