PF-4191834 (PF-04191834) is an orally active, noniron chelating, and non-redox inhibitor of the 5-Lipoxygenase (LOX) (IC50=229 nM), displays ~300-fold selectivity for 5-LOX over 12-LOX and 15-LOX, shows no activity toward the cyclooxygenase enzymes, and is effective in inflammation and pain[1].

Target	IC50: 229 nM (5-LOX), 130 nM (human 5-LOX)[1]
In Vitro	PF-4191834 (PF-04191834) inhibits the synthesis of the 5-LOX products 5-HETE, 5-oxo-ETE, LTB4, and LTE4 with estimated IC50 values between 100 and 190 nM and do not inhibit significantly the COX-1/2 enzymes or the 12- or 15-LOX enzymes at concentrations up to 30 μM[1]. PF-4191834 (PF-04191834) exerts a concentration-dependent inhibition of human 5-LOX, with an IC50 value of 130 nM and an IC80 value of 370 nM[1].
