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.
