Discovery of a novel class of 1,3-dioxane-2-carboxylic acid derivatives as subtype-selective peroxisome proliferator-activated receptor α (PPARα) agonists

A new series of 1,3-dioxane-2-carboxylic acid derivatives was synthesized and evaluated for agonist activity at human peroxisome proliferator-activated receptor (PPAR) subtypes. Structure-activity relationship studies led to the identification of 2-methyl-c-5-[4-(5-methyl-2-phenyl-1,3-oxazol-4-yl)butyl]-1,3-dioxane-r-2-carboxylic acid 4b as a potent PPARα agonist with high subtype selectivity at human receptor subtypes. This compound exhibited a substantial hypolipidemic effect in type 2 diabetic KK-Ay mice.

A new series of 1,3-dioxane-2-carboxylic acid derivatives was identified as potent and subtype-selective human PPARα agonists. Compound 4b exhibits superior hypolipidemic activity in type 2 diabetic KK-Ay mice.Figure optionsDownload as PowerPoint slide
