Daledalin (UK-3557-15) is an antidepressant which was synthesized and trialed for depression in the early 1970s, but was never marketed.[1][2][3] It is a selective norepinephrine reuptake inhibitor, with no significant effects on the reuptake of serotonin and dopamine, and no antihistamine or anticholinergic properties.[2][4]
