Pharmacophore-based design, synthesis, biological evaluation, and 3D-QSAR studies of aryl-piperazines as α1-adrenoceptor antagonists
摘要:
Phenyl-piperazines were designed and synthesized based on pharmacophore for uro-selective alpha(1)-adrenoceptor antagonists and 3D chemical database searching. Within this series, three compounds, 2, 3, and 13, showed similar or better alpha(1)-AR antagonistic activity compared with prazosin. The 3D-QSAR study of these compounds may provide useful information for the development of novel aryl-piperazines as uro-selective alpha(1)-adrenoceptor antagonists, which can be used for the treatment of BPH with fewer side effects.

Phenylpiperazinylalkylamino Substituted Pyridazinones as Potent α1 Adrenoceptor Antagonists
摘要:
QSAR models have been used for designing a series of compounds characterized by a N-phenylpiperazinylalkylamino moiety linked to substituted pyridazinones, which have been synthesized. Measurements of the binding affinities of the new compounds toward the alpha (1a)-, alpha (1b)-, and alpha (1d)-AR cloned subtypes as well as the 5-HT1A receptor have been done validating, at least in part, the estimations of the theoretical models. This study provides insight into the structure activity relationships of the alpha (1)-ARs ligands and their alpha (1)-AR/5-HT1A selectivity.
