  Design and Synthesis of Specific Probes for Human 5-HT₄ Receptor Dimerization Studies

  摘要：

  Recently, human 5-HT4 receptors have been demonstrated to form constitutive dimers in living cells. To evaluate the role of dimerization on the 5-HT4 receptor function, we investigated the conception and the synthesis of bivalent molecules able to influence the dimerization process. Their conception is based on a model of the 5-HT4 receptor dimer derived from protein/protein docking experiments. These bivalent ligands are constituted by two ML10302 units, a specific 5-HT4 ligand, linked through a spacer of different sizes and natures. These synthesized bivalent ligands were evaluated in binding assays and cyclic AMP production on the 5-HT4(e/g) receptor isoform stably transfected in C6 glial cells. Our data showed that bivalent ligands conserved a similar affinity compared to the basal ML10302 unit. Nevertheless, according to the nature and the size of the spacer, the pharmacological profile of ML10302 is more or less conserved. In view of the interest of bivalent ligands for investigating the GPCR dimerization process, these 5-HT4 specific bivalent ligands constitute valuable pharmacological tools for the study of 5-HT4 receptor dimerization.

  G-protein-coupled receptor dimerization directs the design of new drugs that specifically bind to receptor dimers. Here, we generated a targeted series of homobivalent ligands for serotonin 5-HT(4) receptor (5-HT(4)R) dimers composed of two 5-HT(4)R-specific ML10302 units linked by a spacer. The design of spacers was assisted by molecular modeling using our previously described 5-HT(4)R dimer model.

  G蛋白偶联受体二聚体指导了特异性结合受体二聚体的新药的设计。在这里，我们针对5-羟色胺5-HT（4）受体（5-HT（4）R）二聚体生成了一系列针对性的同二价配体，该二聚体由两个通过间隔子连接的5-HT（4）R特异性ML10302单元组成。使用我们之前描述的5-HT（4）R二聚体模型，通过分子建模来辅助间隔基的设计。它们的合成基于Sonogashira-Linstrumelle偶联方法。所有化合物保留与5-HT（4）R的高亲和力结合，但失去了单体ML10302化合物的激动特性。使用基于生物发光共振能量转移（BRET）的检测方法，可监测5-HT（4）二聚体中的构象变化，从而获得二价配体与5-HT（4）R的两个药效基团之间功能相互作用的直接证据。尽管一价ML10302在此测定中无活性，但几种二价衍生物剂量依赖性地增加了BRET信号，表明这两个药效团在功能上与5-HT（4）二聚体相互作用。这些二价
