Abstract:
We report the structure-activity relationships of further analogues in a series of piperazine derivatives as dual inhibitors of serotonin and noradrenaline reuptake, that is, with additional substitution of the phenyl rings, or their replacement by heterocycles. The enantiomers of compounds 1 and 2 were also profiled, and possessed drug-like physicochemical properties. In particular, compound (-)-2 lacked potent inhibitory activity against any of the important cytochromes P(450) and high selectivity over a wide range of receptors, which is unusual for a compound that inhibits human amine transporters.

Aromatic ring substitutions: Substituting the aromatic ring with –OH groups at positions 3 and 4 yields catecholamines (e.g., epinephrine), which have a high affinity for adrenoceptors. Hydrogen bonding between –OH groups and receptors enhances adrenergic activity.
