A high-capacity assay for PPARgamma ligand regulation of endogenous aP2 expression in 3T3-L1 cells.

A novel class of insulin-sensitizing agents, the thiazolidinedines (TZDs), has proven effective in the treatment of type 2 diabetes. These compounds, as well as a subclass of non-TZD insulin-sensitizing agents, have been shown to be peroxisome proliferator-activated receptor (PPAR) gamma agonists. PPARgamma plays a critical role in adipogenesis and PPARgamma agonists have been shown to induce adipocyte differentiation.

MK-0767, a novel dual PPARalpha/gamma agonist, displays robust antihyperglycemic and hypolipidemic activities.

Here, we characterize the actions of MK-0767, a dual ligand of the nuclear receptors peroxisome proliferator-activated receptor (PPAR)alpha and PPARgamma. In cell-based assays, MK-0767 produced potent activation of human PPARgamma and PPARalpha with a gamma:alpha potency ratio of approximately 2. The dual agonist induced high affinity interactions of PPARalpha and PPARgamma with the transcriptional coactivator CBP in vitro.

A novel peroxisome proliferator-activated receptor alpha/gamma dual agonist demonstrates favorable effects on lipid homeostasis.

Patients with type 2 diabetes mellitus exhibit hyperglycemia and dyslipidemia as well as a markedly increased incidence of atherosclerotic cardiovascular disease. Here we report the characterization of a novel arylthiazolidinedione capable of lowering both glucose and lipid levels in animal models. This compound, designated TZD18, is a potent agonist with dual human peroxisome proliferator-activated receptor (PPAR)-alpha/gamma activities.

Localization of PPARdelta in murine central nervous system: expression in oligodendrocytes and neurons.

The peroxisome proliferator-activated receptors (PPARs), PPARdelta, PPARgamma and PPARalpha, comprise a subclass of the supergene family of nuclear receptors. As such they are ligand-regulated transcription factors whose major effects are mediated by altering expression of target genes. PPARdelta has been shown to be ubiquitously expressed in mammals.

Distinct properties and advantages of a novel peroxisome proliferator-activated protein [gamma] selective modulator.

Antidiabetic thiazolidinediones (TZDs) and non-TZD compounds have been shown to serve as agonists of the peroxisome proliferator-activated receptor gamma (PPARgamma). Here, we report the identification and characterization of a novel non-TZD selective PPARgamma modulator (nTZDpa). nTZDpa bound potently to PPARgamma with high selectivity vs.
