A series of 1-substituted pyrrolidin-2-one and pyrrolidine derivatives were synthesised and tested for electrocardiographic, antiarrhythmic, and antihypertensive activity as well as for alpha(1)- and alpha(2)-adrenoceptors binding affinities. Among the newly synthesised derivatives several compounds with 3-(4-arylpiperazin-1-yl)propyl moiety displayed strong antiarrhythmic (7a-12a) and antihypertensive
合成了一系列的1-取代的吡咯烷-2-酮和吡咯烷衍生物,并测试了其心电图,抗心律不齐和抗高血压活性以及α(1)-和α(2)-肾上腺素受体的结合亲和力。在新合成的衍生物中,几种具有3-(4-芳基哌嗪-1-基)丙基的化合物表现出很强的抗心律不齐(7a-12a)和抗高血压(7a-11a)活性。化合物11a,1- [2-乙酰氧基-3- [4-(2-甲氧基苯基)哌嗪-1-基]丙基]吡咯烷-2--2-是最有效的。药理结果和结合研究表明,它们的抗心律不齐和降压作用可能与其α-肾上腺皮质激素特性有关,
