Alternative Name: L-663,536

Chemical Name: 1-[(4-Chlorophenyl)methyl]-3-[(1,1-dimethylethyl)thio]-α,α-dimethyl-5-(1-methylethyl)-1H-Indole-2-propanoic acid

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.

Technical Data

Soluble to 5 mM in ethanol and to 100 mM in DMSO
>98 %
Store at RT
