dose-dependently stimulated phosphatidylinositol turnover in rat brain slices. Moreover, the response to 1-(2-aminoethyl)-3-methyl-8,9-dihydropyrano[3,2-]indole (5, CP-132,484) and 1-(2-aminoethyl)-8,9-dihydropyrano[3,2-e]indole (4) is selectively antagonized by 5-HT2 receptor antagonists establishing these tryptamines as selective 5-HT2 receptor agonists. The high affinity and potency of 5 for 5-HT2 receptors suggests
合成了一系列神经递质5-羟色胺的旋转受限酚类似物,其中5-羟吲哚的5-羟吲哚部分被二氢吡喃[3,2-e]-吲哚(1、3、4和5)和二氢吡喃[2]取代。 ,3-f]吲哚(2)。已经研究了这些化合物的受体结合特征并将其与天然底物血清素进行了比较。二氢吡喃并[3,2-e]吲哚衍生物(1、3、4和5)对5-HT1受体的亲和力较低,但对5-HT2受体的亲和力相同或更高。像血清素一样,这些化合物剂量依赖性地刺激大鼠脑切片中的磷脂酰肌醇转换。此外,对1-(2-氨基乙基)-3-甲基-8,9-二氢吡喃[3,2-]吲哚(5,CP-132,484)和1-(2-氨基乙基)-8,9-二氢吡喃的响应[3,2-e]吲哚(4)被5-HT2受体拮抗剂选择性拮抗,确立了这些色胺为选择性5-HT2受体激动剂。5对5-HT2受体的高亲和力和效力表明,5-羟色胺中的C5-羟基可作为5-HT2受体中的氢键受体,其相互作用的方向向下且
