L-669083 

L-669083 is a leukotriene biosynthesis inhibitor whose structure is based on a mixture of indole and quinoline. In this study, a potent radioiodinated photoaffinity analog of L-689,037, [125I] L-691,678, was developed and characterized for immunoprecipitation studies showing that the quindole series of leukotriene biosynthesis inhibitors directly interact with FLAP. In addition, the results showed that MK-886, L-674,573, and L-689,037 competed with [125I] L-691,678 and [125I] L-669083 for binding to FLAP in a concentration-dependent manner, indicating that these three leukotriene biosynthesis inhibitors share a binding site on FLAP, further demonstrating that FLAP is a suitable target for structurally diverse leukotriene biosynthesis inhibitors.
