McN-5558 is a drug which acts as a selective noradrenaline reuptake inhibitor. It was investigated for potential application as an antidepressant, but was never developed for clinical use.[1][2]
McN-5558 is described as a serotonin–norepinephrine reuptake inhibitor (SNRI) with equilibrium constants (Kis) for various neurotransmitter transporters:[2]
| Compound 37b | norepinephrine transporter (NE) |
dopamine transporter (DAT) |
serotonin transporter (SERT) |
|---|---|---|---|
| racemic | 1.0 | 54.3 | 23.0 |
| (+) | 1.5 | 25.7 | 9.1 |
| (-) | 2570 | 7690 | 2920 |
These data show that virtually all of the binding affinities resides in a single enantiomer. Consequently, the compound displays a very high eudysmic ratio.
