nitrogen atom of common ligands, occupying what may be termed a “secondary” binding site. Using a multivalent approach to lead discovery, we have investigated how varying the position and nature of the secondary binding group can be used as a strategy to achieve the desired 5-HT4 agonist pharmacological profile. During this study, we discovered the ability of amine-based secondary binding groups to impart
5-HT 4受体激动剂(例如替加色罗)已证明可治疗便秘为主的肠易激综合症(IBS-C),该病症是一种高度流行的疾病,其特征在于慢性便秘和肠道推进功能受损,腹胀和疼痛。5-HT 4受体结合位点可以容纳连接至常见配体的胺氮原子的功能和空间上不同的基团,占据所谓的“第二”结合位点。使用多价方法进行前导发现,我们研究了如何将二级结合基团的位置和性质变化用作实现所需5-HT 4的策略。激动剂药理学资料。在这项研究过程中,我们发现了基于胺的二级结合基团能够在5-HT 4激动剂的结合亲和力,选择性和功能效能方面获得非凡的收益。通过这种方法产生的前导物的优化提供了化合物26,其为一种选择性的,口服有效的5-HT 4激动剂,可用于治疗胃肠动力相关的疾病。
