Lipoxygenase

AM679 is a potent and selective FLAP inhibitor with IC50s of 2.2 nM/0.6 nM/154 nM for FLAP binding/hLA/hWB respectively.

PF-4191834 is a novel, potent and selective non-redox 5-lipoxygenase inhibitor effective in inflammation and pain with an IC50=229 nM. displays ~300-fold selectivity for 5-LOX over 12-LOX and 15-LOX, shows no activity toward the cyclooxygenase enzymes.

PGS-IN-1 is a potent inhibitor of prostaglandin synthetase (PGS) with an IC50 of 0.28 μM; also inhibits 5-lipoxygenase with an IC50 of 1.05 μM.

LY 178002 is a potent inhibitor of 5-lipoxygenase, phospholipase A2, with IC50 of 0.6 μM for 5-1ipoxygenase, inhibits cellular production of LTB4 by human polymorphonuclear leukocytes, and shows relatively weak inhibition on cyclooxygenase.

AM 103 is a potent and selective FLAP inhibitor, with an IC50 value of 4.2 nM.
