A dihydroquinolinone moiety was found to be a potent serotonin reuptake inhibitor pharmacophore when combined with certain amines. This fragment was coupled with selected D2 ligands to prepare a series of dual acting compounds with attractive in vitro profiles as dopamine D2 partial agonists and serotonin reuptake inhibitors. Structure-activity studies revealed that the linker plays a key role in contributing to D2 affinity, function, and SRI activity.
- Dopamine D partial agonist
- Serotonin reuptake inhibitor
