A new potent and selective peroxisome proliferator-activated receptor alpha partial agonist displays anti-steatotic effects In vitro and behaves as a safe hypolipidemic and hypoglycemic agent in a diabetic mouse model

A rational drug design approach led to the synthesis of three pairs of enantiomers derived from the peroxisome proliferator-activated receptor (PPAR) pan agonist AL29-26, identifying (S)-2 as a potent and selective PPAR alpha partial agonist. Molecular docking and molecular dynamics simulations elucidated the binding modes of (S)-2 within the ligand-binding domains of PPAR alpha and PPAR gamma. In vitro, (S)-2 demonstrated significant anti-steatotic effects, upregulating key PPAR alpha target genes involved in lipid metabolism. In vivo, (S)-2 exhibited hypolipidemic and antihyperglycemic activity in a diabetic mouse model, outperforming fenofibrate in lowering blood glucose and lipid levels, while showing no toxicity in major organs (artery, kidney, liver, pancreas). The therapeutic effects of ((S)-2 were attributed to its PPAR alpha selectivity, reduced activation of PPAR gamma, and mild protein tyrosine phosphatase 1B (PTP1B) inhibition. These findings highlight (S)-2 as a promising lead compound for the development of safer and more effective treatments for dyslipidemic type 2 diabetes.
