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.

hydroamination of unactivated olefins with primary alkyl amines to selectively furnish secondary amine products. These reactions proceed through aminium radical cation (ARC) intermediates and occur at room temperature undervisiblelight irradiation in the presence of an iridium-based photocatalyst and an aryl thiol hydrogen atom donor. Despite the presence of excess olefin, high selectivities are observed for

Herein we describe the synthesis of a series of new potenttachykinin NK2 receptor antagonists by the modulation of the C‐ and N‐terminal moieties of ibodutant (MEN 15596, 1). The N‐terminal benzo[b]thiophene ring was replaced by different substituted naphthalenes and benzofurans, while further modifications were evaluated at the C‐terminal tetrahydropyran moiety. Most compounds demonstrated a high affinity
本文中,我们描述了一系列新的有效速激肽NK的合成2通过ibodutant的C-和N-末端部分的调制(MEN 15596,受体拮抗剂1)。N末端的苯并[ b ]噻吩环被不同的取代萘和苯并呋喃取代,同时在C末端的四氢吡喃部分评估了进一步的修饰。大多数化合物表现出对人NK 2受体的高亲和力和体外拮抗剂的高效力,表明可以在分子的两个末端引入广泛的取代基,而不会影响与NK 2受体的相互作用。对选定的化合物进行了体内测试,证实了其作为NK的活性2个拮抗剂。特别是,对豚鼠静脉内和静脉内给药后,化合物61b能够拮抗NK 2诱导的结肠收缩,其作用力和作用持续时间与参考化合物1(MEN 15596,ibodutant)完全相同。
