A number of 3-(phenylsulfonyl)thieno[2,3-e][1,2,3]triazolo[1,5-a]pyrimidines were prepared and their 5-HT6 receptor binding affinity and ability to inhibit the functional cellular responses to serotonin were evaluated. 3-[(3-Chlorophenyl)sulfonyl]-N-(tetrahydrofuran-2-ylmethyl)thieno[2,3-e][1,2,3]triazolo[1,5-a]pyrimidin-5-amine 25,26} appeared to be the most active in a functional assay (IC50 = 29
制备了许多3-(苯磺酰基)噻吩并[2,3- e ] [1,2,3]三唑并[1,5- a ]嘧啶,它们与5-HT 6受体的结合亲和力和抑制细胞功能的能力评估对5-羟色胺的反应。3-[(3-氯苯基)磺酰基] -N-(四氢呋喃-2-基甲基)噻吩并[2,3- e ] [1,2,3]三唑并[1,5 - a ]嘧啶-5-胺2 5,26 }似乎是最活跃的在功能测定法(IC 50 = 29.0纳米)和3-(苯基磺酰基) - ñ - (2-噻吩甲基)噻吩并[2,3- ë ] [1,2,3]三唑并[1,5- a ]嘧啶-5-胺2 1,28 }表明,在5-HT的最大亲和力6受体放射性配体结合测定法(ķ我 = 1.7纳米)。对5-HT 2A和5-HT 2B受体亲和力的筛选显示3-(苯磺酰基)噻吩并[2,3- e ] [1,2,3]三唑并[1,5- a ]嘧啶是高度选择性的5- HT 6受体配体。
