متن کاملSynthesis and pharmacological evaluation of pyrrolidin-2-one derivatives as antiarrhythmic, antihypertensive and alpha-adrenolytic agents.
A series of novel arylpiperazines bearing a pyrrolidin-2-one fragment were synthesized and evaluated for their binding affinity for alpha1- and alpha2-adrenoceptors (ARs) as well as their antiarrhythmic and antihypertensive activities. The highest affinity for the alpha1-AR was displayed by 1-{3-[4-(2-chloro-phenyl)-piperazin-1-yl]-propyl}-pyrrolidin-2-one 7, which binds with a pKi = 7.13. The ...
