In this study, a series of fused-heterocyclic derivatives were systematically designed and synthesized using an efficient route, and evaluated in terms of GLP-1R agonist activity. We employed short synthetic steps and reactions that are tolerant of the presence of various functional groups and suitable for parallel operations to enable the rapid generation of libraries of diverse and structurally complex small molecules. Of the compounds synthesized, 3-(8-chloro-6-(trifluoromethyl)imidazo[1,2-a] pyridin-2-yl)phenyl methanesulfonate (8e) was the most potent agonist with an EC50 of 7.89 μM, and thus is the compound with the greatest potential for application. These findings represent a valuable starting point for the design and discovery of small-molecule GLP-1R agonists that can be administered orally.
在这项研究中,我们系统地设计并合成了一系列融合杂环衍生物,并评估其作为GLP-1R激动剂的活性。我们采用了简短的合成步骤和可以容忍各种功能团的反应,适合平行操作,从而快速生成多样化和结构复杂的小分子库。在合成的化合物中,3-(8-氯-6-(三氟甲基)咪唑[1,2-a]吡啶-2-基)苯甲烷磺酸酯(8e)是最强的激动剂,EC50为7.89μM,因而是应用潜力最大的化合物。这些发现为设计和发现可口服给药的小分子GLP-1R激动剂提供了宝贵的起点。
