synthesized and evaluated for their binding affinity for α1- and α2-adrenoceptors (ARs), as well as their antiarrhythmic, and antihypertensive activities. The highest affinity for the α1-AR was displayed by 1-3-[4-(2-ethoxy-phenyl)-piperazin-1-yl]-2-hydroxy-propyl}-3,3-diphenylpyrrolidin-2-one (7), which binds with a pKi = 7.28. The highest affinity for the α2-AR was shown by 1-3-[4-(2-methoxy-ph
一系列新颖芳基哌嗪轴承3,3- diphenylpyrrolidin -2-酮片段的合成和评价了它们的结合亲和力为α 1 -和α 2 -肾上腺素受体(ARS),以及它们的抗心律失常和抗高血压活性。为α的最高亲和力1 -AR由1-显示3- [4-(2-乙氧基-苯基) -哌嗪-1-基] -2-羟基-丙基} -3,3- diphenylpyrrolidin -2-一个(7),与ap K i = 7.28绑定。为α的最高亲和力2 -AR用1-所示3- [4-(2-甲氧基-苯基) -哌嗪-1-基] -2-羟基-丙基} -3,3- diphenylpyrrolidin -2-一(5),其与ap K i = 6.68绑定。化合物7 中被加评价体外功能测试了其α亲和力1B -和α 1D -AR,这给了pA的2 α 1B = 6.55和PA 2 α 1D = 7.26。在所测试的化合物中,在麻醉
