  Design, Synthesis, and Structure–Activity Relationships of Highly Potent 5-HT₃ Receptor Ligands

  摘要：

  The 5-HT3 receptor, a pentameric ligand-gated ion channel (pLGIC), is an important therapeutic target. During a recent fragment screen, 6-chloro-N-methyl-2-(4-methyl-1,4-diazepan-1-yl)quinazolin-4-amine (1) was identified as a 5-HT3R hit fragment. Here we describe the synthesis and structure activity relationships (SAR) of a series of (iso)quinoline and quinazoline compounds that were synthesized and screened for 5-HT3R affinity using a [H-3]granisetron displacement assay. These studies resulted in the discovery of several high affinity ligands of which compound 22 showed the highest affinity (pK(i) > 10) for the 5-HT3 receptor. The observed SAR is in agreement with established pharmacophore models for 5-HT3 ligands and is used for ligand-receptor binding mode prediction using homology modeling and in silico docking approaches.

  From a series of small fragments that was designed to probe the histamine H-4 receptor (H4R), we previously described quinoxaline-containing fragments that were grown into high affinity H4R ligands in a process that was guided by pharmacophore modeling. With a scaffold hopping exercise and using the same in silico models, we now report the identification and optimization of a series of quinazoline-containing H4R compounds. This approach led to the discovery of 6-chloi-o-N-(furan-3-yl)methyl)2-(4-methylpiperzin-1-yl)quinazolin-4-amine (VUF10499, 54) and 6-chloro-2-(4-methylpiperazin-1-yl)-N-(thiophen-2-ylmethyl)quinazolin-4-amine (VUF10497, 55) as potent human H4R inverse agonists (pK(i) = 8.12 and 7.57, respectively). Interestingly, both compounds also possess considerable affinity for the human histamine Hi receptor (H1R) and therefore represent a novel class of dual action H1R/H4R ligands, a profile that potentially leads to added therapeutic benefit. Compounds from this novel series of quirlazolines are antagonists at the rat H4R and were found to possess anti-inflammatory properties in vivo in the rat.
