T0070907 PPAR inhibitor

Cat.No.S2871

T0070907 is a potent inhibitor of PPARγ (peroxisome proliferator activator receptor γ ) that induces G2/M arrest and enhances the effect of radiation in human cervical cancer cells through mitotic catastrophe. It also acts as an antagonist of PPARγ that suppresses breast cancer cell proliferation and motility via both PPARgamma-dependent and -independent mechanisms.

Mechanism of Action

Targets/IC50/Ki
PPARγ [1]
In vitro

T0070907 is a potent and selective PPARγ antagonist. With an apparent binding affinity of 1 nM, this compound covalently modifies PPARγ on cysteine 313 in helix 3 of human PPARγ2. It blocks PPARγ function in both cell-based reporter gene and adipocyte differentiation assays. Consistent with its role as an antagonist of PPARγ, this chemical blocks agonist-induced recruitment of coactivator-derived peptides to PPARγ in a homogeneous time-resolved fluorescence-based assay and promotes recruitment of the transcriptional corepressor NCoR to PPARγ in both glutathione S-transferase pull-down assays and a PPARγ/retinoid X receptor (RXR) α-dependent gel shift assay. Studies with mutant receptors suggest that it modulates the interaction of PPARγ with these cofactor proteins by affecting the conformation of helix 12 of the PPARγ ligand-binding domain. Interestingly, whereas the T0070907-induced NCoR recruitment to PPARγ/RXRα heterodimer can be almost completely reversed by the simultaneous treatment with RXRα agonist LGD1069, this compound treatment has only modest effects on LGD1069-induced coactivator recruitment to the PPARγ/RXRα heterodimer. [1] This chemical treatment inhibits proliferation, invasion and migration but does not significantly affect apoptosis. Molecular inhibition using a dominant negative (Δ462) receptor yields similar results. It also mediates a dose-dependent decrease in phosphorylation of PPARγ, and its ability to bind to DNA, and may directly affect mitogen-activated protein kinase signaling. [2]

Kinase Assay
Ligand Binding Assay
To determine the binding affinity of T0070907 to the PPARs, scintillation proximity assay (SPA) is performed with the following modifications. A 90-μl reaction contains SPA buffer (10 mm KH2PO4, 10 mm KH2PO4, 2 mm EDTA, 50 mm NaCl, 1 mm dithiothreitol, 2 mmCHAPS, 10% (v/v) glycerol, pH 7.1), 50 ng of GST-PPARγ (or 150 ng of GST-PPARα, GST-PPARδ), 5 nm 3H-labeled radioligands, and 5 μl of this compound in Me2SO. After incubation for 1 h at room temperature, 10 μl of polylysine-coated SPA beads (at 20 mg/ml in SPA buffer) are added, and the mixtureis incubated for 1 h before reading in Packard Topcount.
In vivo

Lipopolysaccharide preconditioning significantly attenuates the development of renal dysfunction, hepatocellular injury, and circulatory failure as well as the increase in the plasma levels of interleukin-1 [beta] caused by severe endotoxemia. This compound can attenuate all of these beneficial effects afforded by preconditioning with lipopolysaccharide [3]
