  4-Benzyl-1H-imidazoles with Oxazoline Termini as Histamine H₃ Receptor Agonists

  摘要：

  Research on the therapeutic applications of the histamine H-3 receptor (H3R) has traditionally focused on antagonists/inverse agonists. In contrast, H3R acyonists have received less attention despite their potential use in several disease areas. The lower availability of H3R agonists not only hampers their full therapeutic exploration, it also prevents an unequivocal understanding of the structural requirements for H3R activation. In the light of these important issues, we present our findings on 4-benzyl-1H-imidazole-based H3R agonists. Starting from two high throughput screen hits (10 and 11), the benzyl side chain was altered with lipophilic groups using combinatorial and classical chemical approaches (compounds 12-31). Alkyne- or oxazolino-substituents gave excellent affinities and agonist activities up to the single digit nM range. Our findings further substantiate the growing notion that basic ligand sidechains are not necessary for H3R activation and reveal the oxazolino group as a hitherto unexplored functional group in H3R research.
