Biological Activity
An inhibitor of leukotriene biosynthesis (IC50 = 3 nM in human polymorphonuclear leukocytes). Acts by inhibiting 5-lipoxygenase-activating protein (FLAP) (IC50 = 30 nM for inhibition of [125I]-L-691,678 photoaffinity labelling). Also moderately potent PPARα antagonist (IC50 = 0.5-1 μM). Orally active in vivo.
