GW9662是一种选择性PPAR拮抗剂,作用于PPARγ,IC50为3.3 nM,作用于PPARγ比作用于PPARα和PPARδ选择性强100到1000倍。A selective, irreversible, and effective PPARγ antagonist that also acts as a FXR and PXR agonist.
Information
GW9662 is a selective PPAR antagonist forPPARγwithIC50of 3.3 nM in a cell-free assay, with at least 10- to 600-fold functional selectivity in cells with PPARγ versus PPARα and PPARδ.
In vitro
GW9662 binds to Cys(285) on PPARgamma which is conserved among all three PPARs. GW9662 acts as an antagonist of PPARgamma which is confirmed in an assay of adipocyte differentiation inhibition. GW9662 prevents activation of PPARγ and inhibits growth of human mammary tumour cell lines (MCF7, MDA-MB-468, MDA-MB-231) with IC50 of 20 μM-30 μM, suggesting either the existence of PPARγ agonistic properties of GW9662 or growth-inhibitory mechanisms independent of PPARγ. Co-treatment with both Rosiglitazone (50 μM) and GW9662 (10 μM) results in statistically lower viable cell numbers after 7 days in MDA-MB-231 cells. PPARγ1 ligands could suppress RANKL-induced osteoclast formation in primary murine myeloid (BMs) and RAW264.7 cells. Importantly, suppression by these ligands is reversed in a concentration-dependent fashion with GW 9662 (2 μM). GW 9662 (2 μM) blocks IL-4 suppression of osteoclast formation in BMs. GW 9662 (1 μM) blocks RANKL activation of NF-κB in RAW264.7 cells. GW9662 (10 μM) inhibits hormone- and agonist-induced adipogenesis of primary preadipocytes from patients with thyroid eye disease.
In vivo
Pretreatment with LPS (1 mg/kg i.p.) significantly attenuates all markers of renal injury and dysfunction caused by ischemia/reperfusion (I/R) injury in rats. Most notably, GW9662 (1 mg/kg i.p.) abolishes the protective effects of LPS.
