Synthesis and evaluation of 5-benzylidenethiazolidine-2,4-dione derivatives for the treatment of non-alcoholic fatty liver disease.

Twenty-two 5-benzylidenethiazolidine-2,4-dione derivatives (TZDs) were synthesized and evaluated for their potency on adipogenesis of 3T3-L1 adipocytes by measuring the expression of adiponectin protein. Among them, compared to rosiglitazone, 3V was found to upregulate the adiponectin protein expression and downregulate the secretion of leptin protein in 3T3-L1 adipocytes at a respective concentration of 10 µM. With respect to high-fat/high-calorie (HF/HC) diet-induced non-alcoholic fatty liver disease (NAFLD) in Wistar rats, oral administration of 3V could reduce liver weight, visceral fat, and improve serum levels of biochemical markers.
