Discovery of a potent, selective, and less flexible selective norepinephrine reuptake inhibitor (sNRI).

ABSTRACT

The design, synthesis, and SAR of a series of ring-constrained norepinephrine reuptake inhibitors are described. A substantially rigid inhibitor with potent functional activity at the transporter (IC(50)=8 nM) was used to develop a model for the distance and orientation of key features necessary for interaction with the norepinephrine transporter (NET).
