1,3-dioxane carboxylic acid derivatives were prepared based on our previous studies directed towards identifying novel pharmacophore for the development of PPAR α/γ dual agonists. Based on the typical topology of PPAR agonists we focused our design approach on modifying lipophilic tail and prepared a series of compounds by replacing the oxazole moiety of our previously reported compound with optimized lipophilic groups. Compound 8a was found to be a weak PPAR activator but exhibited potent hypolipidemic and anti-hyperglycemic activities in vivo due to superior bioavailability, whereas 8f exhibited potent in vitro and invivo effects. The activity of 8f is further supported by molecular docking study.
1,3- 二氧六环羧酸衍生物的制备基于我们之前的研究,这些研究旨在为 PPAR α/γ 双激动剂的开发确定新的药理基础。根据 PPAR 激动剂的典型拓扑结构,我们将设计方法的重点放在了亲脂性尾部的修饰上,并用优化的亲脂基团取代了之前报道的化合物中的噁唑分子,制备了一系列化合物。研究发现,化合物 8a 是一种弱 PPAR 激活剂,但由于其生物利用度较高,在体内表现出了强效的降血脂和降血糖活性,而 8f 则在体外和体内都表现出了强效作用。分子对接研究进一步证实了 8f 的活性。
