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。 GW9662 is a selective PPAR antagonist for PPARγ with IC50 of 3.3 nM, with at least 100 to 1000-fold functional selectivity in cells with PPARγ versus PPARα and PPARδ. A selective, irreversible, and effective PPARγ antagonist that also acts as a FXR and PXR agonist.
