GW9662 Usage And Synthesis

Description

GW-9662 (22978-25-2) is a selective PPARγ antagonist (IC50 = 3.3, 32 and 2000 nM for PPARγ, PPARα and PPARδ respectively).1 Blocks the inhibition of osteoclast formation induced by IL-4 (1-2 μM).2 Displays anticancer activity inhibits growth of human mammary tumor cell lines.3 GW-9662 is a useful tool for dissecting the involvement of PPARγ in cellular physiology.4,5

Chemical Properties

Off-White Solid

Uses

An irreversible PPAR antagonist

Uses

GW9662 has been used as a peroxisome proliferator activated receptor γ (PPARγ) antagonist in human pluripotent stem cells, in phenylephrine stimulated cardiomyocytes and to inhibit the protective effect of telmisartan pheochromocytoma, PC12 cells.

Uses

A cell-permeable, selective and irreversible PPAR antagonist (IC50 = 3.3 nM, 32 nM, and 2 for PPAR, PPARa, and PPARd, respectively). Reported to covalently modify a cysteine residue in the binding site of PPAR. At a concentration of 10 , also

Definition

ChEBI: GW 9662 is a member of benzamides.

Biological Activity

Selective PPAR γ antagonist (IC 50 values are 3.3, 32 and 2000 nM for PPAR γ , PPAR α and PPAR δ respectively). Blocks the inhibition of osteoclast formation induced by IL-4 in the low micromolar range (1-2 μ M), therefore is more potent than BADGE (2,2-Bis[4-(2,3-epoxypropoxy)phenyl]propane ). Anticancer, inhibits growth of human mammary tumor cell lines.

Biochem/physiol Actions

GW9662 (2-chloro-5-nitrobenzanilide) binds to the ligand binding site of the peroxisome proliferator activated receptor γ (PPARγ) and results in the inhibition of adipocyte differentiation. It favors cell growth suppression in breast cancer cell lines even in the presence of PPARγ agonist rosiglitazone. It stimulates M2c macrophages differentiation and triggers growth arrest-specific 6 (Gas6) expression. GW9662 co treatment with other PPARγ ligands elicits antiproliferative effects on the glioblastoma stem cells and could be a potent therapeutic agent.
