blx3887

BLX3887 is a highly potent and selective inhibitor of 15-lipoxygenase type 1 (15-LO-1), exhibiting an IC50 of 32 nM in cell-free enzyme assays, with marked selectivity over 15-LO-2, which it does not inhibit, as well as over 5-LO (IC50 = 472 nM) and 12-LO (IC50 = 3,310 nM). BLX3887 selectively suppresses 15-LO metabolite production in eosinophils over neutrophils at 10 μM while additionally inhibiting endocytosis and migration of human peripheral blood mononuclear cell–derived dendritic cells in vitro, highlighting its utility in inflammatory and immune cell signaling research.
