5-b']difuran-4-yl)-2-aminopropane 2, and their affinity, functional potency, and intrinsic activity were assessed using cells stably expressing the rat 5-HT(2A) receptor. The behavioral pharmacology of these new analogs was also evaluated in the two-lever drug discrimination paradigm. Although all of the hybrid isomers had similar, nanomolar range receptor affinities, those with the smaller furanyl ring at the arene
具有构象刚性的呋喃基部分代替烷氧基芳烃环取代基的苯基烷基胺先前已被证明在该化学类别中对血清素 5-HT(2A) 受体具有最高的亲和力和激动剂功能效力。此外,当两个呋喃环都扩展为更大的双吡喃环系统时,亲和力会下降。本论文报告了一系列“混合”苯并呋喃基-苯并吡喃基苯基烷基胺的合成和药理学评价,以进一步探测 5-羟色胺 5-HT(2A) 激动剂结合位点内结合口袋的大小。因此,制备了 4(ab)、5(ab) 和 6 作为母体化合物 8-溴-1-(2,3,6,7-四氢苯并[1,2-b:4,5- b']difuran-4-yl)-2-aminopropane 2,以及它们的亲和力、功能效力,使用稳定表达大鼠 5-HT(2A) 受体的细胞评估内在活性。这些新类似物的行为药理学也在两杆药物鉴别范式中进行了评估。尽管所有杂化异构体都具有相似的纳摩尔范围的受体亲和力,但在芳烃 2 位 (4a-b) 处具有较小
