Resumen:
Dual peroxisome proliferator-activated receptor-α/γ(PPARα/γ) agonists regulate both lipid and glucose homeostasisunder different metabolic conditions and can exert anti-inflammatoryactivity. We investigated the potential dual PPARα/γ agonism ofprenylated benzopyrans polycerasoidol (1) and polycerasoidin (2)and their derivatives for novel drug development. Nine semisyntheticderivatives were prepared from the natural polycerasoidol (1) andpolycerasoidin (2), which were evaluated for PPARα, -γ, -δ andretinoid X receptor-α activity in transactivation assays. Polycerasoidol(1) exhibited potent dual PPARα/γ agonism and low cytotoxicity.Structure−activity relationship studies revealed that a free phenolgroup at C-6 and a carboxylic acid at C-9′ were key features for dualPPARα/γ agonism activity. Molecular modeling indicated the relevance of these groups for optimal ligand binding to thePPARα and PPARγ domains. In addition, polycerasoidol (1) exhibited a potent anti-inflammatory effect by inhibitingmononuclear leukocyte adhesion to the dysfunctional endothelium in a concentration-dependent manner via RXRα/PPARγinteractions. Therefore, polycerasoidol (1) can be considered a hit-to-lead molecule for the further development of novel dualPPARα/γ agonists capable of preventing cardiovascular events associated with metabolic disorders.
