aim to develop new potent and selective ligands of 5‐HT3‐type serotonin receptors and to acquire more information on their structure‐affinity relationships, new thieno[2,3‐d]pyrimidine derivatives 32–39 were synthesized and their binding to 5‐HT3 versus 5‐HT4 receptors was studied. Some of these new compounds exhibit good affinity for cortical 5‐HT3 receptors, but not for 5‐HT4 receptors. Among these
为了开发 5-HT3 型 5-羟色胺受体的新型强效选择性配体并获得更多关于其结构亲和关系的信息,合成了新的噻吩并 [2,3-d] 嘧啶衍生物 32-39 并将它们与研究了 5-HT3 与 5-HT4 受体。其中一些新化合物对皮质 5-HT3 受体表现出良好的亲和力,但对 5-HT4 受体则不然。在这些衍生物中,6-乙基-4-(4-甲基-1-哌嗪基)-2-(甲硫基)噻吩并[2,3-d]嘧啶32是最有效的配体(Ki = 67 nM);它在豚鼠结肠中充当 5-HT3 受体功能的竞争性拮抗剂。通过使用受体建模和比较对接分析其与 5-HT3A 受体的结合相互作用。
