The peroxisome proliferator activated receptors PPARalpha, PPARgamma, and, PPARdelta are ligand-activated transcription factors that play a key role, in lipid homeostasis. The fibrates raise circulating levels of, high-density lipoprotein cholesterol and lower levels of triglycerides in, part through their activity as PPARalpha agonists; however, the low, potency and restricted selectivity of the fibrates may limit their, efficacy, and it would be desirable to develop more potent and selective, PPARalpha agonists. Modification of the selective PPARdelta agonist 1, (GW501516) so as to incorporate the 2-aryl-2-methylpropionic acid group of, the fibrates led to a marked shift in potency and selectivity toward, PPARalpha agonism. Optimization of the series gave 25a, which shows EC50 =, 4 nM on PPARalpha and at least 500-fold selectivity versus PPARdelta and, PPARgamma. Compound 25a (GW590735) has been progressed to clinical trials, for the treatment of diseases of lipid imbalance. | The peroxisome proliferator activated receptors PPARalpha, PPARgamma, and, PPARdelta are ligand-activated transcription factors that play a key role, in lipid homeostasis.
