showed that the presence of the 3-(4-piperidyl)-1H-indole group or its 5-methoxy derivative, as well as a para substitution with –OCH3 or –F in the aryl ring of 4-aryl-5,6,7,8-tetrahydro-pyrido[1,2-c]pyrimidine, results in an increased affinity for both the 5-HT1A receptors and SERT. In contrast, the presence of the 2-methyl-3-(4-piperidyl)-1H-indole group resulted in a considerable decrease in binding
合成了4-芳基-5,6,7,8-四氢吡啶并[1,2- c ]嘧啶的衍生物。这些化合物含有3-(4-哌啶基)-1H-吲哚残基或其5-甲氧基或2-甲基衍生物。进行了体外结合试验,以确定化合物对大鼠大脑皮层中5-HT 1A受体和血清素转运蛋白(SERT)的亲和力。进行了体内研究,特别是诱导性低温测试和强迫游泳测试,以确定突触前和突触后5-HT 1A受体的激动/拮抗活性。使用分子建模技术确定所选化合物在5-HT 1A的结合模式受体和SERT。特区分析表明,3-(4-哌啶基)的存在-1 ħ -吲哚基或它的5-甲氧基衍生物,以及一对位取代有-OCH 3或-F 4 -芳基的芳基环-5,6,7,8-四氢-吡啶并[1,2- c ]嘧啶对5-HT 1A受体和SERT的亲和力均增加。相反,2-甲基-3-(4-哌啶基)-1 H-吲哚基的存在导致结合亲和力显着降低。
