MBX-8025 is an agonist of peroxisome proliferator-activated receptor δ (PPARδ).1 It is greater than 750- and 2,500-fold selective for PPARδ over PPARα and PPARγ. MBX-8025 (10 mg/kg per day for eight weeks) reduces increases in fasting blood glucose and serum insulin levels, and decreases insulin resistance in Alms1 mutant (foz/foz) mice fed an atherogenic diet as a model of diet-induced obesity, type 2 diabetes, and non-alcoholic steatohepatitis (NASH).2 It also decreases serum alanine transaminase (ALT), as well as serum and hepatic cholesterol and triglyceride, levels and reduces markers of NASH in the same model.
