A series of N-[2-[(substituted chroman-8-yl)oxy]ethyl]-4-(4-methoxyphenyl)butylamines was prepared and examined for their 5-HT1A receptor antagonist activity. The parent compound 3a and seven analogs bearing five kinds of substituents on the chroman ring were prepared from the corresponding 8-hydroxychroman intermediates. Radioligand binding assays proved the compounds 3a-h to have high affinity for
制备了一系列的N- [2-[(取代的苯并吡喃-8-基)氧基]乙基] -4-(4-甲氧基苯基)丁胺,并检查了它们的5-HT1A受体拮抗剂活性。由相应的8-羟基苯并二氢吡喃中间体制备母体化合物3a和在苯并吡喃环上带有五种取代基的七个类似物。放射性配体结合试验证明化合物3a-h对大鼠海马5-HT1A受体具有高亲和力,对肾上腺素α1和多巴胺D2受体具有不同的选择性。在用表达人5-HT1A受体的CHO细胞进行的福斯科林刺激的腺苷酸环化酶测定中评估了它们的拮抗作用。在该系列中,C6-氟类似物3c对5-HT1A受体显示出极强的亲和力(Ki = 0.22 nM)和拮抗作用(EC50 = 13 nM)。
