Product Description

GW9662 (GW-9662; GW 9662) is an irreversible and selective inhibitor of PPAR (peroxisome proliferator-activated receptor) with potential anticancer activity. It inhibits PPARγ with an IC50 of 3.3 nM in a cell-free assay, and shows >100-fold selectivity for PPARγ over PPARα and PPARδ. GW9662 prevented activation of PPARgamma and inhibited growth of human mammary tumour cell lines. GW9662 may permit use of anti-ER strategies to inhibit breast cancer in ER- patients. GW9662 suppresses the cell viability with IC50 values ranging from 20-30μM.

Biological Activity I Assay Protocols (From Reference)
Targets
PPARγ: (IC50 = 3.3 nM)
PPARα: (IC50 = 32 nM)
PPARδ: (IC50 = 2000 nM)
ln Vitro
GW9662 has the ability to suppress radioligand binding to PPARγ, PPARα, and PPARδ, with corresponding pIC50 values of 8.48±0.27 (IC50=3.3 nM; n = 10), 7.49±0.17 (IC50=32 nM; n = 9), and 5.69±0.17 (IC50=2000 nM; n = 3). The binding studies with PPARα and PPARδ show that GW9662 is 10- and 600-fold less effective, respectively, with a nanomolar IC50 against PPARγ. GW9662 effectively and selectively blocks full-length PPARγ in cell-based reporter assays[1]. When paired with either 50 μM BRL 49653 (P=0.001) or 10 μM GW9662 (P=0.01) alone, co-treatment with both 50 μM BRL 49653 and 10 μM GW9662 leaves a significantly less number of viable cells after 7 days[2].
ln Vivo
Both BADGE- and GW9662(1 mg/kg, ip)-treated mice had significantly greater bone marrow (BM) nucleated cell counts than the aplastic anemia (AA) group[3]. In rats, GW9662 (1 mg/kg, ip) significantly reduces the renoprotective benefits of lipopolysaccharide (LPS)[4].
Enzyme Assay
Binding Assays. [1]
SPAs for all three PPARs were performed as previously described for PPARγ. In brief, the human PPARα, PPARγ, and PPARδ ligand binding domains (LBDs) were expressed in E. coli as polyhistidine-tagged fusion proteins. Receptors were immobilized on SPA beads (Amersham Pharmacia) by addition of the desired receptor (15 nM) to a slurry of streptavidin-modifed SPA beads (0.5 mg/mL) in assay buffer. The mixture was allowed to equilibrate for at least 1 h at room temperature, and the beads were pelleted by centrifugation at 1000g. The supernate was discarded, and the beads were resuspended in the original volume of fresh assay buffer with gentle mixing. The centrifugation/resuspension procedure was repeated, and the resulting slurry of receptor-coated beads was used immediately or stored at 4 °C for up to 1 week before use. [3H]GW2331, [3H]rosiglitazone, and [3H]GW2443 were used as radioligands for determination of competition binding to PPARα, PPARγ, and PPARδ, respectively. Unless otherwise indicated, the buffer used for all assays was 50 mM HEPES (pH 7), 50 mM NaCl, 5 mM CHAPS, 0.1 mg/mL BSA, and 10 mM DTT. For some experiments, the HEPES (pH 7) was replaced with 50 mM Tris (pH 8).
Preparation of GW9662-Modified PPARγ for Mass Spectral Analysis. [1]
A stock solution of GW9662 in dimethyl sulfoxide was added to a 20 μM solution of PPARγ in 50 mM Tris (pH 8), 50 mM NaCl, 5 mM CHAPS, 0.1 mg/mL BSA, and 10 mM DTT. The final concentration of GW9662 was 40 μM. The solution was incubated at 4 °C followed by mass spectral analysis as described below.
Cell Assay
Cell-Based Reporter Assays.[1]
The ability of GW9662 to activate PPAR-mediated reporter gene transcription was assessed using GAL4 chimeras of the human receptors and a (UAS)5-tk-SPAP reporter plasmid as previously described for PPARγ, PPARα, and PPARδ. GW9662 antagonism of ligand-induced gene transcription was measured as previously described. Antagonism of agonist-induced reporter gene transcription was done by titrating varying concentrations of GW9662 in the presence of a constant concentration of activating ligand. The activating ligands used were 100 nM rosiglitazone for PPARγ, 8 nM GW7647 for PPARα, and 0.55 μM GW2433 for PPARδ, respectively.
The effects of GW9662 on activation of PPARγ, PPARα, and PPARδ were also assessed using full-length human receptors and a reporter construct, (L-FABP)4-tk-Dual-LUC, containing four copies of the L-FABP PPRE upstream of the minimal herpesvirus thymidine kinase promoter and a luciferase reporter gene. The receptor plasmids contained the appropriate full-length PPAR cDNA plus 9 base pairs of Kozak consensus sequence cloned into the TOPO site of pcDNA3.1-TOPO. Briefly, HEK293 cells were cultured in Minimum Essential Media containing 10% fetal calf serum, 1% penicillin/streptomycin, and 1% fungizone in a humidified incubator (5% CO2 in air) at 37 °C. The cells were seeded at 2 × 104 cells per well in 96 well culture plates the day prior to assay execution. Transfection was accomplished using PolyFect according to the manufacturers' instructions. Transfection mixtures for each well contained 0.167 μg of PPAR plasmid, 0.167 μg of LFABP reporter, and 0.167 μg of a renilla luciferase plasmid as transfection control. Cells were incubated with the transfection mixture for 5 h before treatment with either compound or vehicle for 48 h. Culture plates were assayed using the Dual Luciferase assay system according to the manufacturers' instructions.
Animal Protocol
Treatment of mice[3]
PPARγ antagonists, BADGE or GW9662, were dissolved in dimethyl sulfoxide (DMSO) and stored at −20°C. The aliquots were diluted with PBS to a final concentration of 10% DMSO and administrated by daily intraperitoneal injection at 30 mg/kg for BADGE, or at 1 mg/kg for GW9662, from one day prior to the experiment and continued for up to 2 weeks. In the FVB AA model, some mice were injected with cyclosporine A (CsA, 50 mg/kg/day) starting 1 hour after the LN injection, and continued for 5 days as immunosuppression. At the end of the experiments, the mice were euthanized by CO2 inhalation.
Methods, including peripheral blood (PB) and BM cell counting, flow cytometry, RNA isolation and gene expression analysis by PCR array, protein extraction and immunoblotting, cytokine measurement, histology using confocal microscopy, calcium flux assay and cell culture are detailed in the Online Supplementary Methods.
