The in vitro binding affinities of these compounds were also examined for 5-HT1A receptor sites. Structure-activity relationships within these series are discussed. One of these compounds, (1R*,2S*,-3R*,4S*)-N-[4-[4-(2-pyrimidinyl)-1-piperazinyl]butyl]-2,3- bicyclo[2.2.1]heptanedicarboximide (1: tandospirone), was found to be equipotent with buspirone in its anxiolytic activity and more anxio-selective
合成了一系列带有ω-(4-芳基和4-杂芳基-1-
哌嗪基)烷基的环状
酰亚胺,并在体内测试其抗焦虑活性。还检查了这些化合物的体外结合亲和力的5-HT1A受体位点。讨论了这些系列中的构效关系。这些化合物之一,(1R *,2S *,-3R *,4S *)-N- [4- [4-(4-
嘧啶基)-1-
哌嗪基]丁基] -2,3-双环[2.2.1已发现]
庚烷二甲
酰亚胺(1:tandospirone)与
丁螺环酮具有相同的抗焦虑活性,并且比
丁螺环酮和地西epa具有更高的选择性。Tandospirone(1)目前正在作为一种选择性
抗焦虑药进行临床评估。
