Abstract:
Continuing our research aimed at obtaining new compounds with high affinity and selectivity toward alpha(1)-AR, a new series of arylpiperazine derivatives was designed, synthesized, and biologically tested. The new compounds 1-17 are characterized by a phenylphthalazin-1(2H)-one fragment connected through an alkyl chain to an arylpiperazine residue. The pharmacological profile of these compounds was evaluated for their affinity and selectivity toward alpha(1)-AR, alpha(2)-AR and toward 5HT(1A) serotoninergic receptor. A discussion on the structure-activity relationship (SAR) of these compounds is also reported.

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.
