To synthesize and evaluate new arylpiperazine derivatives for α1-adrenoreceptor blocking activity.
Synthetic approach to create arylpiperazine derivatives with acetophenone substituents.
In vitro screening of α1-adrenoreceptor activity using rabbit thoracic aorta and measuring relaxation response.
Evaluated diastolic effects in rabbit thoracic aorta, prostate, and bladder smooth muscle.
Characterized antagonistic effects on isolated rat vas deferens, spleen, and aorta to assess tissue selectivity.
Compounds 6 and 7 exhibited significant vasodilatory effects.
The S-enantiomer was more effective than the R-enantiomer in diastolic activity.
Compound 17 showed 18-fold higher selectivity for the α1D subtype compared to α1B, indicating reduced cardiovascular side effects.
